Whether and how delirium and sleep quality in the intensive care unit (ICU) are linked remains unclear. A recent randomised trial reported nocturnal low-dose dexmedetomidine (DEX) significantly reduces incident ICU delirium. Leeds Sleep Evaluation Questionnaire (LSEQ) scores were similar between intervention (DEX; n=50) and control (placebo (PLA); n=50) groups. We measured the association between morning LSEQ and delirium occurrence in the prior 24 hours (retrospective analysis) and the association between morning LSEQ and delirium occurrence in the following 24 hours (predictive analysis).

Post hoc analysis of randomised controlled trial data.

Adult ICU patients (n=100) underwent delirium screening twice a day using the Intensive Care Delirium Screening Checklist (ICDSC) if Richmond Agitation Sedation Scale (RASS) was ≥-3 and patient-reported sleep quality evaluations at 0900 daily with the LSEQ if RASS was ≥-1.

The analysis included all 24-hour study periods with LSEQ documentation and matched delirdelirium occurrence (OR (per 1 point LSEQ change) 1.02, 95% CI 0.99 to 1.05).

The sleep quality ICU patients perceive neither affects nor predicts delirium occurrence.

To assess the health impacts and environmental consequences of adherence to national dietary recommendations (the Eatwell Guide (EWG)) in the UK.

A secondary analysis of multiple observational studies in the UK.

Adults from the European Prospective Investigation into Cancer - Oxford(EPIC-Oxford), UK Biobank and Million Women Study, and adults and children aged 5 and over from the National Diet and Nutrition Survey (NDNS).Primary and secondary outcome measures risk of total mortality from Cox proportional hazards regression models, total greenhouse gas emissions (GHGe) and blue water footprint (WF) associated with 'very low' (0-2 recommendations), 'low' (3-4 recommendations) or 'intermediate-to-high' (5-9 recommendations) adherence to EWG recommendations.

Less than 0.1% of the NDNS sample adhere to all nine EWG recommendations and 30.6% adhere to at least five recommendations. Polyethylenimine mouse Compared with 'very low' adherence to EWG recommendations, 'intermediate-to-high adherence' was associated with a reduced risk diets in the UK that are essential for the health of people and the planet in the Anthropocene.The Pacific Islands are estimated to have among the highest global burdens of hearing loss, however, hearing health services are limited throughout this region. The provision of hearing aid is desirable, but should be delivered in accordance with WHO recommendations of appropriate and locally sustainable services. Large-scale hearing aid donation programmes to the Pacific Islands raise ethical questions that challenge these recommendations.The aim of this paper is to consider the ethical implications of large-scale hearing aid donation programmes to Samoa, a nation of the Pacific Islands. Evaluation of both 'Western' and 'Pacific Island' perspectives reveals important cross-cultural differences regarding attitudes to donation programmes. We attempt to offer possible solutions that satisfy both ethical frameworks, and which should enable us to deliver an effective hearing health service for Samoa. These solutions may be translational and benefit other Pacific Island nations in a similar context.In their recent article, 'Why lockdown of the elderly is not ageist and why levelling down equality is wrong', Savulescu and Cameron argue for selective isolation of the elderly as an alternative to general lockdown. An important part of their argument is the claim that the latter amounts to 'levelling down equality' and that this is 'unethical' or even 'morally repugnant'. This response argues that they fail to justify either part of this claim the claim that levelling down is always morally wrong is subject to challenges that Savulescu and Cameron do not consider; and a policy of maintaining general lockdown does not constitute levelling down, as it provides absolute benefits to those who would be worse off under selective isolation.Infective endocarditis (IE) is uncommon and has, in the past, been most often caused by viridans group streptococci (VGS). Due to the indolent nature of these organisms, the phrase 'subacute bacterial endocarditis', so-called 'SBE', was routinely used as it characterised the clinical course of most patients that extended for weeks to months. However, in more recent years, there has been a significant shift in the microbiology of IE with the emergence of staphylococci as the most frequent pathogens, and for IE due to Staphylococcus aureus, the clinical course is acute and can be associated with sepsis. Moreover, increases in IE due to enterococci have occurred and have been characterised by treatment-related complications and worse outcomes. These changes in pathogen distribution have been attributed to a diversification in the target population at risk of IE. While prosthetic valve endocarditis and history of IE remain at highest risk of IE, the rise in prevalence of injection drug use, intracardiac device implantations and other healthcare exposures have heavily contributed to the existing pool of at-risk patients. This review focuses on common IE pathogens and their impact on the clinical profile of IE.Agonistic antibodies targeting CD137 have been clinically unsuccessful due to systemic toxicity. Because conferring tumor selectivity through tumor-associated antigen limits its clinical use to cancers that highly express such antigens, we exploited extracellular adenosine triphosphate (exATP), which is a hallmark of the tumor microenvironment and highly elevated in solid tumors, as a broadly tumor-selective switch. We generated a novel anti-CD137 switch antibody, STA551, which exerts agonistic activity only in the presence of exATP. STA551 demonstrated potent and broad antitumor efficacy against all mouse and human tumors tested and a wide therapeutic window without systemic immune activation in mice. STA551 was well tolerated even at 150 mg/kg/week in cynomolgus monkeys. These results provide a strong rationale for the clinical testing of STA551 against a broad variety of cancers regardless of antigen expression, and for the further application of this novel platform to other targets in cancer therapy. SIGNIFICANCE Reported CD137 agonists suffer from either systemic toxicity or limited efficacy against antigen-specific cancers.
