RESUMEN

Exposure to high temperatures can have detrimental effects on cognitive processing and this is concerning for firefighters who routinely work in extreme temperatures. Whilst past research has studied the effects of heat on firefighter cognition, findings are mixed, and no work has measured the time course of cognitive recovery. This study compared working memory, vigilance, and cognitive flexibility of 37 firefighters before and after they engaged in a live-fire training exercise with temperatures exceeding 115 °C. To assess recovery, cognition was measured on exiting the fire, then 20- and 40-minutes post-fire. Results showed impaired vigilance and cognitive flexibility (increased errors, slower responses) immediately after the fire, but recovery at 20-minutes. These findings indicate that a live indoor fire negatively impacts cognitive processing, but this effect is relatively short-lived and return to baseline functioning is seen 20-minutes after exiting the fire. The findings could be used to inform re-entry and cooling decisions.


Acute heat stress may affect cognitive processing, posing a health and safety risk to firefighters. This study demonstrates impaired cognition following a firefighter training exercise in temperatures exceeding 115 °C. Cognition recovered as core body temperature returned to normal, providing evidence for a 20-minute cooling period following exposure to extreme heat.

RESUMEN

BACKGROUND: Neurogenic detrusor overactivity incontinence (NDOI) is often inadequately managed with oral therapy. OBJECTIVE: To assess efficacy and safety of abobotulinumtoxinA (aboBoNT-A; Dysport®; Ipsen Ltd.) according to etiology of NDOI. DESIGN, SETTING, AND PARTICIPANTS: Two phase III, randomized, double-blind studies (CONTENT1 [NCT02660138] conducted in Asia, Europe and North America; CONTENT2 [NCT02660359] conducted in the Americas, Asia, Europe and Oceania) both included patients with spinal cord injury (SCI) or multiple sclerosis (MS), with inadequately managed NDOI, regularly performing clean intermittent catheterization (CIC). INTERVENTION: Patients in CONTENT1 and CONTENT2 received aboBoNT-A injections 600 U (n = 162)/800 U (n = 161), or placebo (n = 162) into the detrusor muscle. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary endpoint: mean change from baseline in number of NDOI episodes/week at Week 6. Secondary endpoints: proportion of patients with no NDOI episodes; incontinence-related quality of life (I-QoL); urodynamic parameters; and time-to-retreatment. Safety was also assessed. Statistical analyses were conducted for pooled populations by etiology (aboBoNT-A doses vs. placebo). RESULTS AND LIMITATIONS: Of 485 randomized patients, 341 (70%) and 144 (30%) had SCI and MS etiologies, respectively. A significant reduction was observed in mean NDOI episodes/week at Week 6 with both aboBoNT-A doses versus placebo in the SCI (all p < 0.001) and MS (all p < 0.01) groups, as well as significant improvements in I-QoL and urodynamic parameters. Median time-to-retreatment was longer in patients with MS (48-62 weeks across doses) than those with SCI (39-44 weeks). Safety data were similar between etiologies. Urinary tract infection was the most frequent adverse event; similar numbers were reported across treatment groups. CONCLUSIONS: AboBoNT-A was well tolerated and significantly improved continence and bladder function, and QoL, in patients with SCI or MS with NDOI performing regular CIC. PATIENT SUMMARY: AboBoNT-A injections improved QoL, symptoms, and bladder function in patients with SCI or MS with bladder muscle overactivity that causes incontinence.

RESUMEN

BACKGROUND: AbobotulinumtoxinA (aboBoNT-A) solution is a new ready-to-use formulation developed to reduce preparation time and improve reproducibility of injections. OBJECTIVE: To further evaluate treatment of moderate-to-severe glabellar lines (GLs) using pooled data from 2 Phase III studies. METHODS: Following double-blind treatment with 50 U aboBoNT-A solution (n = 251) or placebo (n = 123), GL severity was assessed by investigators (ILA) and subjects (SSA). Other assessments included subject-reported time to onset, subject satisfaction, FACE-Q, and adverse events. RESULTS: One month after aboBoNT-A solution treatment, 88% had none-or-mild GLs at maximum frown and 93% had ≥1-grade improvement in ILA (similar for SSA), 24% to 27% remaining improved at Month 6. Glabellar lines responder rates remained higher than placebo throughout Month 6 ( p < .001). Almost two-thirds of subjects reported onset within 3 days, nearly a quarter reporting effect by Day 1. Subject satisfaction with GL appearance, and FACE-Q satisfaction with facial appearance overall and psychological well-being were also improved over placebo throughout Month 6, p < .05. Treatment-related adverse events were nonserious and mild or moderate. CONCLUSION: Pooled analysis confirmed a duration of effect on GLs of up to 6 months for aboBoNT-A solution, with onset starting within 24 hours, high subject satisfaction, and improved psychological well-being. The treatment was well tolerated.

RESUMEN

BACKGROUND: A ready-to-use liquid formulation of abobotulinumtoxinA (aboBoNT-A solution) has been developed. OBJECTIVES: The aim of this study was to assess the long-term efficacy and safety of aboBoNT-A solution for the treatment of glabellar lines. METHODS: This was a multicenter, multinational, Phase III study (NCT02493946), with randomized double-blind placebo-controlled (DBPC; 2:1 aboBoNT-A solution 50 U/placebo) and open-label (4 cycles aboBoNT-A solution) periods; additional patients were recruited into the open-label period. Patients were 18 to 65 years old, BoNT-naïve, and dissatisfied/very dissatisfied with moderate/severe glabellar lines at maximum frown. Investigator's live assessment (primary endpoint)/subject's self-assessment of glabellar line severity at maximum frown, patient satisfaction with glabellar line appearance, and FACE-Q patient-reported scales (facial appearance overall, psychological well-being, aging) were assessed. Adverse events were monitored. Analyses were performed on DBPC and long-term analysis (LTA; all patients receiving ≥1 aboBoNT-A solution injection) populations. RESULTS: Responder rates for the investigator's live assessment, the subject's self-assessment, and patient satisfaction were consistent at Day 29 postinjection across repeat LTA cycles (82.2%-87.8%, 62.8%-80.6%, and 72.2%-87.8%, respectively), with statistically significantly higher responder rates vs placebo (DBPC cycle: 81.6% vs 0.8%, 68.1% vs 2.3%, and 83.1% vs 5.7%, respectively; all P < 0.0001). Consistent improvements on FACE-Q scales occurred with repeat cycles (DBPC cycle: aboBoNT-A solution vs placebo, P < 0.0001). No new or unexpected adverse events, or neutralizing antibodies, were observed. CONCLUSIONS: These results support the long-term efficacy and safety of aboBoNT-A solution, and its superiority over placebo, for treatment of glabellar lines in adults.

RESUMEN

We report a large epidemic (n = 126) of keratoconjunctivitis predominantly with two lineages of adenovirus (AdV) type D8 in patients seen in eye casualty between march and August 2019. Other AdV species identified by viral sequencing included B, C, and E. Despite various features of more severe eye disease being present, these were not significantly different between the different AdV species, with similar rates of pseudomembrane formation and keratitis observed in patients with AdV species B as for those with AdV species D.

RESUMEN

Top-down attentional settings can persist between two unrelated tasks, influencing visual attention and performance. This study investigated whether top-down contextual information in a second task could moderate this "attentional inertia" effect. Forty participants searched through letter strings arranged horizontally, vertically, or randomly and then made a judgement about road, nature, or fractal images. Eye movements were recorded to the picture search and findings showed greater horizontal search in the pictures following horizontal letter strings and narrower horizontal search following vertical letter strings, but only in the first 1000 ms. This shows a brief persistence of attentional settings, consistent with past findings. Crucially, attentional inertia did not vary according to image type. This indicates that top-down contextual biases within a scene have limited impact on the persistence of previously relevant, but now irrelevant, attentional settings.

RESUMEN

This paper By Ward et al. (Journal of Child Psychology and Psychiatry, 2019) in the issue of the JCPP, is an excellent example of preparing a new programme for parents with children at high risk of present and future behaviour problems. It was to be delivered in a very deprived population in a township in South Africa. We discuss the paper but also raise questions about developing new programmes when they are already successful programmes available and discuss whether it is time for programme developers to meet to discuss what works best and for whom.

RESUMEN

Research shows that emotional stimuli can capture attention, and this can benefit or impair performance, depending on the characteristics of a task. Additionally, whilst some findings show that attention expands under positive conditions, others show that emotion has no influence on the broadening of attention. The current study investigated whether emotional real-world scenes influence attention in a visual search task. Participants were asked to identify a target letter embedded in the centre or periphery of emotional images. Identification accuracy was lower in positive images compared to neutral images, and response times were slower in negative images. This suggests that real-world emotional stimuli have a distracting effect on visual attention and search. There was no evidence that emotional images influenced the spatial spread of attention. Instead, it is suggested that findings may provide support for the argument that positive emotion encourages a global processing style and negative emotion promotes local processing.

RESUMEN

PURPOSE: Overactive bladder affects 12% to 17% of the general population and almost a third experience urinary incontinence, which may severely impact health related quality of life. Oral anticholinergics are the mainstay of pharmacological treatment but they are limited by inadequate efficacy or side effects, leading to a high discontinuation rate. We report the results of the first large (557 patients), phase 3, placebo controlled trial of onabotulinumtoxinA in patients with overactive bladder and urinary incontinence inadequately managed with anticholinergics. MATERIALS AND METHODS: Eligible patients with overactive bladder, 3 or more urgency urinary incontinence episodes in 3 days and 8 or more micturitions per day were randomized 1:1 to receive intradetrusor injection of onabotulinumtoxinA 100 U or placebo. Co-primary end points were the change from baseline in the number of urinary incontinence episodes per day and the proportion of patients with a positive response on the treatment benefit scale at posttreatment week 12. Secondary end points included other overactive bladder symptoms and health related quality of life. Adverse events were assessed. RESULTS: OnabotulinumtoxinA significantly decreased the daily frequency of urinary incontinence episodes vs placebo (-2.65 vs -0.87, p <0.001) and 22.9% vs 6.5% of patients became completely continent. A larger proportion of onabotulinumtoxinA than placebo treated patients reported a positive response on the treatment benefit scale (60.8% vs 29.2%, p <0.001). All other overactive bladder symptoms improved vs placebo (p ≤0.05). OnabotulinumtoxinA improved patient health related quality of life across multiple measures (p <0.001). Uncomplicated urinary tract infection was the most common adverse event. A 5.4% rate of urinary retention was observed. CONCLUSIONS: OnabotulinumtoxinA 100 U showed significant, clinically relevant improvement in all overactive bladder symptoms and health related quality of life in patients inadequately treated with anticholinergics and was well tolerated.

RESUMEN

IntroductionThe United Kingdom is in the fourth season of introducing a universal childhood influenza vaccine programme. The 2016/17 season saw early influenza A(H3N2) virus circulation with care home outbreaks and increased excess mortality particularly in those 65 years or older. Virus characterisation data indicated emergence of genetic clusters within the A(H3N2) 3C.2a group which the 2016/17 vaccine strain belonged to. Methods: The test-negative case-control (TNCC) design was used to estimate vaccine effectiveness (VE) against laboratory confirmed influenza in primary care. Results: Adjusted end-of-season vaccine effectiveness (aVE) estimates were 39.8% (95% confidence interval (CI): 23.1 to 52.8) against all influenza and 40.6% (95% CI: 19.0 to 56.3) in 18-64-year-olds, but no significant aVE in ≥ 65-year-olds. aVE was 65.8% (95% CI: 30.3 to 83.2) for 2-17-year-olds receiving quadrivalent live attenuated influenza vaccine. Discussion: The findings continue to provide support for the ongoing roll-out of the paediatric vaccine programme, with a need for ongoing evaluation. The importance of effective interventions to protect the ≥ 65-year-olds remains.
