Are Caregivers' Feeding Competence and Autonomy Associated with Healthier Restaurant Food Purchases for Their Child at Fast Food or Counter Service Restaurants? A Cross-Sectional Study in a Diverse Sample of U.S. Caregivers.

This study examined the cross-sectional relationship between caregivers' perceived competence and autonomy (as defined by the Self-Determination Theory) and their fast food or counter service restaurant food purchases (side dishes, beverage, and dessert) for their child. A U.S. national convenience sample of caregivers with at least one 3-12-year-old child completed an online survey with questions adapted from the Intrinsic Motivation Inventory that measured perceived competence and autonomy for feeding fruits and vegetables and limiting sugar-sweetened beverages (SSBs) and desserts. The survey included four questions asking about their fast food or counter service restaurant food purchases (side dish, beverage, and dessert). We applied logistic and multinomial logistic regression models to examine the associations between competence or autonomy and restaurant orders. Competence and autonomy were associated with ordering fruits and vegetables as side dishes (OR [95% CI], 1.14 [1.06, 1.24] and 1.09 [1.03, 1.14], respectively). However, higher competence was also associated with ordering desserts at restaurants and higher autonomy was associated with lower odds of ordering water. These findings will inform interventions and programs that aim to support caregivers' psychological needs, like competence and autonomy, to promote supportive environments and healthier restaurant purchases for their children.

The longitudinal association between caregivers' perceived competence and autonomy and children's dietary consumption before and 10 months into the COVID-19 pandemic.

The COVID-19 pandemic has been stressful, potentially affecting caregivers' feeding choices. Caregivers play a role in shaping children's diets, yet few studies have explored how their competence and autonomy, defined by the Self-Determination Theory, impact children's diets. We examined the relationship between caregivers' autonomy and competence and their feeding practices before and during the first year of the pandemic. A national convenience sample of caregivers with 3-12-year-old children completed an online survey during two time-periods. Questions adapted from the Intrinsic Motivation Inventory measured perceived competence and autonomy for feeding fruits and vegetables (F/V) and limiting sugar-sweetened beverages (SSBs) and desserts. National Health and Nutrition Examination Survey Dietary Screener questions measured children's consumption of F/V, SSBs, and desserts. Paired t-tests examined how child consumption and caregiver's perceived competence and autonomy changed, and logistic regressions examined whether caregivers' competence and autonomy predicted the change in child consumption and if changes in competence and autonomy were associated with changes in child consumption. Caregivers (n = 597) were mostly Black/African American (33.0%) or Latina/o/x (42.7%) and older than 30 years (84.1%). Children's consumption did not change overall, but caregivers' competence for feeding F/V increased, and their competence for limiting SSBs and desserts decreased. Caregiver competence and autonomy before COVID-19 did not predict child dietary consumption during the pandemic. However, change in competence was a significant predictor of the change in child consumption of F/V [OR (95%CI): 0.70 (0.57, 0.86)]. The association between caregiver's perceived competence for feeding F/V and child consumption remained positive and significant in both periods [OR (95%CI) pre and during COVID: 2.09 (1.69, 2.57) - 2.40 (1.88, 3.06)]. This study can inform behavioral interventions supporting caregivers' competence and autonomy around feeding choices.

The application of precision dosing in the use of sertraline throughout pregnancy for poor and ultrarapid metabolizer CYP 2C19 subjects: A virtual clinical trial pharmacokinetics study.

Sertraline is known to undergo changes in pharmacokinetics during pregnancy. CYP 2C19 has been implicated in the interindividual variation in clinical effect associated with sertraline activity. However, knowledge of suitable dose titrations during pregnancy and within CYP 2C19 phenotypes is lacking. A pharmacokinetic modeling virtual clinical trials approach was implemented to: (i) assess gestational changes in sertraline trough plasma concentrations for CYP 2C19 phenotypes, and (ii) identify appropriate dose titration strategies to stabilize sertraline levels within a defined therapeutic range throughout gestation. Sertraline trough plasma concentrations decreased throughout gestation, with maternal volume expansion and reduction in plasma albumin being identified as possible causative reasons. All CYP 2C19 phenotypes required a dose increase throughout gestation. For extensive metabolizer (EM) and ultrarapid metabolizer (UM) phenotypes, doses of 100-150 mg daily are required throughout gestation. For poor metabolizers (PM), 50 mg daily during trimester 1 followed by a dose of 100 mg daily in trimesters 2 and 3 are required.

Recruiting people with severe mental illness through community pharmacies: real-world experiences from a UK study.

BACKGROUND: Proxy recruitment of patient participants through community pharmacies may be a valuable strategy to maximise participation. This paper focuses on the feasibility of such a recruitment strategy for research involving people who experience severe mental illness. METHODS: Fifty-three community pharmacies, including 50 'Research Ready' pharmacies, were asked to recruit people with severe mental illness for participation in research. Pharmacists were asked to provide participant information to anyone presenting a prescription meeting specific criteria. RESULTS: Thirteen recruitment sites (25%) (from 4 distinct organisations) were approved to recruit patient participants. Eighty-five percent (n = 11) failed to recruit any potential participants. CONCLUSIONS: Proxy recruitment of people with severe mental illness through community pharmacies was challenging with challenges in both pharmacy- and participant-recruitment. Further investigation into supporting community pharmacists' engagement with recruiting patients with SMI as research participants is required.

Precision dosing-based optimisation of paroxetine during pregnancy for poor and ultrarapid CYP2D6 metabolisers: a virtual clinical trial pharmacokinetics study.

OBJECTIVE: Paroxetine has been demonstrated to undergo gestation-related reductions in plasma concentrations, to an extent which is dictated by the polymorphic state of CYP 2D6. However, knowledge of appropriate dose titrations is lacking. METHODS: A pharmacokinetic modelling approach was applied to examine gestational changes in trough plasma concentrations for CYP 2D6 phenotypes, followed by necessary dose adjustment strategies to maintain paroxetine levels within a therapeutic range of 20-60 ng/ml. KEY FINDINGS: A decrease in trough plasma concentrations was simulated throughout gestation for all phenotypes. A significant number of ultrarapid (UM) phenotype subjects possessed trough levels below 20 ng/ml (73-76%) compared to extensive metabolisers (EM) (51-53%). CONCLUSIONS: For all phenotypes studied, there was a requirement for daily doses in excess of the standard 20 mg dose throughout gestation. For EM, a dose of 30 mg daily in trimester 1 followed by 40 mg daily in trimesters 2 and 3 is suggested to be optimal. For poor metabolisers (PM), a 20 mg daily dose in trimester 1 followed by 30 mg daily in trimesters 2 and 3 is suggested to be optimal. For UM, a 40 mg daily dose throughout gestation is suggested to be optimal.

Evaluation of the effectiveness and acceptability of intramuscular clozapine injection: illustrative case series.

AIMS AND METHOD: A series of eleven patients prescribed intramuscular clozapine at five UK sites is presented. Using routinely collected clinical data, we describe the use, efficacy and safety of this treatment modality. RESULTS: We administered 188 doses of intramuscular clozapine to eight patients. The remaining three patients accepted oral medication. With the exception of minor injection site pain and nodules, side-effects were as expected with oral clozapine, and there were no serious untoward events. Nine patients were successfully established on oral clozapine with significant improvement in their clinical presentations. CLINICAL IMPLICATIONS: Although a novel formulation in the UK, we have shown that intramuscular clozapine can be used safely and effectively when the oral route is initially refused.

Quetiapine dose optimisation during gestation: a pharmacokinetic modelling study.

OBJECTIVES: The second-generation antipsychotic quetiapine has been demonstrated to undergo gestation-related changes in pharmacokinetics. This study applied pharmacokinetic modelling principles to investigate the mechanism of these changes and to propose new dosing strategies to counteract these changes. METHODS: A pharmacokinetic modelling approach was implemented using virtual population groups. Changes in quetiapine trough plasma concentration during gestation were quantified across all trimesters, and dose adjustment strategies were applied to counteract these changes by targeting a therapeutic range of 50-500 ng/ml throughout gestation. KEY FINDINGS: The application of the model during gestation predicted a decrease in trough concentration. A maximum decrease of 58% was predicted during trimester 2, and being associated with a statistically significant decrease in oral clearance at gestation week 25, 204 l/h ± 100.8 l/h compared with non-pregnant subjects, 121.9 l/h ± 51.8 l/h. A dosing optimisation strategy identified that dose increases to 500-700 mg twice daily would result in 32-55% of subjects possessing trough concentration in excess of 50 ng/ml. CONCLUSIONS: Quetiapine doses in pregnancy should be increased to 500-700 mg twice daily to counteract a concomitant increase in metabolic clearance, increase in volume of distribution and decrease in plasma protein binding.
