The link between childhood obesity and both television viewing and television advertising have previously been examined. We sought to investigate the frequency and type of food and beverage placements in children-specific television broadcasts and, in particular, differences between programme genres.

Content of five weekdays of children-specific television broadcasting on both UK (BBC) and Irish (RTE) television channels was summarized. Food and beverage placements were coded based on type of product, product placement, product use and characters involved. A comparison was made between different programme genres: animated, cartoon, child-specific, film, quiz, tween and young persons’ programming.

A total of 1155 (BBC=450; RTE=705) cues were recorded giving a cue every 4·2 min, an average of 12·3 s/cue. The genre with most cues recorded was cartoon programming (30·8 %). For the majority of genres, cues related to sweet snacks (range 1·8–23·3 %) and sweets/candy (range 3·6–25·8 %) featured highly. Fast-food (18·0 %) and sugar-sweetened beverage (42·3 %) cues were observed in a high proportion of tween programming. Celebratory/social motivation factors (range 10–40 %) were most common across all genres while there were low proportions of cues based on reward, punishment or health-related motivating factors.

The study provides evidence for the prominence of energy-dense/nutrient-poor foods and beverages in children’s programming. Of particular interest is the high prevalence of fast-food and sugar-sweetened beverage cues associated with tween programming. These results further emphasize the need for programme makers to provide a healthier image of foods and beverages in children’s television.

Delirium affects all higher cortical functions supporting complex information processing consistent with widespread neural network impairment. We evaluated the relative prominence of delirium symptoms throughout episodes to assess whether impaired consciousness is selectively affecting certain brain functions at different timepoints.

Twice-weekly assessments of 100 consecutive patients with DSM-IV delirium in a palliative care unit used the Delirium Rating Scale Revised-98 (DRS-R98) and Cognitive Test for Delirium (CTD). A mixed-effects model was employed to estimate changes in severity of individual symptoms over time.

Mean age = 7 0.2 ± 10.5 years, 51% were male, and 27 had a comorbid dementia. A total of 323 assessments (range 2–9 per case) were conducted, but up to 6 are reported herein. Frequency and severity of individual DRS-R98 symptoms was very consistent over time even though the majority of patients (80%) experienced fluctuation in symptom severity over the course of hours or minutes. Over time, DRS-R98 items for attention (88–100%), sleep–wake cycle disturbance (90–100%), and any motor disturbance (87–100%), and CTD attention and vigilance were most frequently and consistently impaired. Mixed-effects regression modeling identified only very small magnitudes of change in individual symptoms over time, including the three core domains.

Attention is disproportionately impaired during the entire episode of delirium, consistent with thalamic dysfunction underlying both an impaired state of consciousness and well-known EEG slowing. All individual symptoms and three core domains remain relatively stable despite small fluctuations in symptom severity for a given day, which supports a consistent state of impaired higher cortical functions throughout an episode of delirium.

Delirium phenomenology is understudied.

To investigate the relationship between cognitive and non-cognitive delirium symptoms and test the primacy of inattention in delirium.

People with delirium (n=100) were assessed using the Delirium Rating Scale-Revised-98(DRS-R98)and Cognitive Test for Delirium (CTD).

Sleep-wake cycle abnormalities and inattention were most frequent, while disorientation was the least frequent cognitive deficit. Patients with psychosis had either perceptual disturbances or delusions but not both. Neither delusions nor hallucinations were associated with cognitive impairments. Inattention was associated with severity of other cognitive disturbances but not with non-cognitive items. CTD comprehension correlated most closely with non-cognitive features of delirium.

Delirium phenomenology is consistent with broad dysfunction of higher cortical centres, characterised in particular by inattention and sleep-wake cycle disturbance. Attention and comprehension together are the cognitive items that best account for the syndrome of delirium. Psychosis in delirium differs from that in functional psychoses.

Prescribing in everyday practice frequently deviates from evidence-based guidelines. Previous work compared practice in a community mental health service with evidence-based guidelines and identified factors related to suboptimal prescribing. This study reports the impact of a multifaceted intervention on prescribing practice. A Prescribing Practice Quality (PPQ) score was generated from six key aspects of prescribing at initial assessment and again 1 year later after an intervention to reduce suboptimal prescribing practices.

A total of 264 patients were attending the service at both the initial and follow-up phase and were thus exposed to the prescribing intervention. In this population, PPQ scores were significantly lower at follow-up (0.96 v. 0.67, P<0.001). Improved prescribing practice was predicted by receipt of adjunctive supportive inputs, such as anxiety management (P=0.003).

Similarly, mean PPQ scores substantially decreased when the total patient population was considered at each time point (0.75 in 2001 and 0.52 in 2002). These results suggest a reduction in both the initiation and continuation of suboptimal practices.

Prescribing in real-world settings can be improved by interventions that target multiple aspects of service activity. The provision of supportive inputs is a key factor in improving practice.
