Cochrane acute respiratory infections group's stakeholder engagement project identified systematic review priority areas

Objective: Cochrane acute respiratory infections (ARIs) group conducts systematic reviews of the evidence for treatment and prevention of ARIs. We report the results of a prioritization project, aiming to identify highest priority systematic review topics. Study Design/Setting: The project consisted of two phases. Phase 1 analyzed the gap between existing randomized controlled trials and Cochrane systematic reviews (reported previously). Phase 2 (reported here) consisted of a two-round survey. In round 1, respondents prioritized 68 topics and suggested up to 10 additional topics; in round 2, respondents prioritized top 25 topics from round 1. Results: Respondents included clinicians, researchers, systematic reviewers, allied health, patients, and carers, from 33 different countries. In round 1, 154 respondents identified 20 priority topics, most commonly selecting topics in nonspecific ARIs, influenza, and common cold. Fifty respondents also collectively suggested 134 additional topics. In round 2, 78 respondents prioritized top 25 topics, most commonly in the areas of nonspecific ARIs, pneumonia, and influenza. Conclusion: We generated a list of priority systematic review topics to guide the Cochrane ARI group's systematic review work for the next 24 months. Stakeholder involvement enhanced the transparency of the process and will increase the usability and relevance of the group's work to stakeholders

Delayed antibiotic prescriptions for respiratory infections

Background: Concerns exist regarding antibiotic prescribing for respiratory tract infections (RTIs) owing to adverse reactions, cost, and antibacterial resistance. One proposed strategy to reduce antibiotic prescribing is to provide prescriptions, but to advise delay in antibiotic use with the expectation that symptoms will resolve first. This is an update of a Cochrane Review originally published in 2007, and updated in 2010 and 2013. Objectives: To evaluate the effects on clinical outcomes, antibiotic use, antibiotic resistance, and patient satisfaction of advising a delayed prescription of antibiotics in respiratory tract infections. Search methods: For this 2017 update we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, Issue 4, 2017), which includes the Cochrane Acute Respiratory Infection Group's Specialised Register; Ovid MEDLINE (2013 to 25 May 2017); Ovid Embase (2013 to 2017 Week 21); EBSCO CINAHL Plus (1984 to 25 May 2017); Web of Science (2013 to 25 May 2017); WHO International Clinical Trials Registry Platform (1 September 2017); and ClinicalTrials.gov (1 September 2017). Selection criteria: Randomised controlled trials involving participants of all ages defined as having an RTI, where delayed antibiotics were compared to immediate antibiotics or no antibiotics. We defined a delayed antibiotic as advice to delay the filling of an antibiotic prescription by at least 48 hours. We considered all RTIs regardless of whether antibiotics were recommended or not. Data collection and analysis: We used standard Cochrane methodological procedures. Three review authors independently extracted and collated data. We assessed the risk of bias of all included trials. We contacted trial authors to obtain missing information. Main results: For this 2017 update we added one new trial involving 405 participants with uncomplicated acute respiratory infection. Overall, this review included 11 studies with a total of 3555 participants. These 11 studies involved acute respiratory infections including acute otitis media (three studies), streptococcal pharyngitis (three studies), cough (two studies), sore throat (one study), common cold (one study), and a variety of RTIs (one study). Five studies involved only children, two only adults, and four included both adults and children. Six studies were conducted in a primary care setting, three in paediatric clinics, and two in emergency departments. Studies were well reported, and appeared to be of moderate quality. Randomisation was not adequately described in two trials. Four trials blinded the outcomes assessor, and three included blinding of participants and doctors. We conducted meta-analysis for antibiotic use and patient satisfaction. We found no differences among delayed, immediate, and no prescribed antibiotics for clinical outcomes in the three studies that recruited participants with cough. For the outcome of fever with sore throat, three of the five studies favoured immediate antibiotics, and two found no difference. For the outcome of pain related to sore throat, two studies favoured immediate antibiotics, and three found no difference. One study compared delayed antibiotics with no antibiotic for sore throat, and found no difference in clinical outcomes. Three studies included participants with acute otitis media. Of the two studies with an immediate antibiotic arm, one study found no difference for fever, and the other study favoured immediate antibiotics for pain and malaise severity on Day 3. One study including participants with acute otitis media compared delayed antibiotics with no antibiotics and found no difference for pain and fever on Day 3. Two studies recruited participants with common cold. Neither study found differences for clinical outcomes between delayed and immediate antibiotic groups. One study favoured delayed antibiotics over no antibiotics for pain, fever, and cough duration (moderate quality evidence for all clinical outcomes - GRADE assessment). There were either no differences for adverse effects or results favoured delayed antibiotics over immediate antibiotics (low quality evidence - to GRADE assessment) with no significant differences in complication rates. Delayed antibiotics resulted in a significant reduction in antibiotic use compared to immediate antibiotics prescription (odds ratio (OR) 0.04, 95% confidence interval (CI) 0.03 to 0.05). However, a delayed antibiotic was more likely to result in reported antibiotic use than no antibiotics (OR 2.55, 95% CI 1.59 to 4.08) (moderate quality evidence - GRADE assessment). Patient satisfaction favoured delayed over no antibiotics (OR 1.49, 95% CI 1.08 to 2.06). There was no significant difference in patient satisfaction between delayed antibiotics and immediate antibiotics (OR 0.65, 95% CI 0.39 to 1.10) (moderate quality evidence - GRADE assessment). None of the included studies evaluated antibiotic resistance. Authors' conclusions: For many clinical outcomes, there were no differences between prescribing strategies. Symptoms for acute otitis media and sore throat were modestly improved by immediate antibiotics compared with delayed antibiotics. There were no differences in complication rates. Delaying prescribing did not result in significantly different levels of patient satisfaction compared with immediate provision of antibiotics (86% versus 91%) (moderate quality evidence). However, delay was favoured over no antibiotics (87% versus 82%). Delayed antibiotics achieved lower rates of antibiotic use compared to immediate antibiotics (31% versus 93%) (moderate quality evidence). The strategy of no antibiotics further reduced antibiotic use compared to delaying prescription for antibiotics (14% versus 28%). Delayed antibiotics for people with acute respiratory infection reduced antibiotic use compared to immediate antibiotics, but was not shown to be different to no antibiotics in terms of symptom control and disease complications. Where clinicians feel it is safe not to prescribe antibiotics immediately for people with respiratory infections, no antibiotics with advice to return if symptoms do not resolve is likely to result in the least antibiotic use while maintaining similar patient satisfaction and clinical outcomes to delaying prescription of antibiotics. Where clinicians are not confident in using a no antibiotic strategy, a delayed antibiotics strategy may be an acceptable compromise in place of immediate prescribing to significantly reduce unnecessary antibiotic use for RTIs, and thereby reduce antibiotic resistance, while maintaining patient safety and satisfaction levels. Editorial note: As a living systematic review, this review is continually updated, incorporating relevant new evidence as it becomes available.

‘C’était moi mais ce n’était pas moi’: portrayal of the disabled body in Catherine Breillat’s Abus de faiblesse (2013)

Writer/director Catherine Breillat’s most recent film, Abus de faiblesse (2013), explores an important moment of bodily transition: the change from able to disabled body. This semi-autobiographic film follows the story of film director Maud (Breillat’s alter ego), who forms a destructive relationship with a conman, Vilko, after she suffers a disabling stroke. This film shows consistency with Breillat’s previous work in its exploration of the constructed nature of the female body onscreen. In the past the filmmaker has portrayed moments of trauma and transition (such as childbirth, loss of virginity or rape) to subvert processes of objectification. The article argues that Abus de faiblesse challenges and subverts representation of the post-menopausal and disabled body onscreen. The film interrogates binary oppositions such as able/disabled and independence/dependency to challenge representations of the disabled body as ‘other’. With reference to scholarly work on disability and the ageing female body, the article suggests that Maud’s sadomasochistic relationship with Vilko is driven by a quest to retain her subjectivity after her stroke. The article demonstrates that the film dissects the feared and the unknown territory of the ageing female body

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder

Neuraminidase inhibitors for preventing and treating influenza in healthy adults

BACKGROUND: Neuraminidase inhibitors (NI) are recommended for use against influenza and its complications in inter-pandemic years and during pandemics. OBJECTIVES: To assess the effects of NIs in preventing and treating influenza, its transmission, and its complications in otherwise healthy adults, and to estimate the frequency of adverse effects. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009, issue 3) which contains the Acute Respiratory Infections Group's Specialised Register, MEDLINE (1950 to August 2009) and EMBASE (1980 to August 2009). SELECTION CRITERIA: Randomised controlled trials (RCTs) or quasi-randomised placebo-controlled trials of NIs in healthy adults exposed to naturally occurring influenza. DATA COLLECTION AND ANALYSIS: Two review authors independently applied inclusion criteria, assessed trial quality, and extracted data. We structured the comparisons into prophylaxis, treatment, and adverse events, with further subdivision by outcome and dose. MAIN RESULTS: We identified four prophylaxis, 12 treatment and four post-exposure prophylaxis trials. In prophylaxis compared to placebo, NIs had no effect against influenza-like illnesses (ILI) (risk ratio (RR) ranging from 1.28 for oral oseltamivir 75 mg daily to 0.76 for inhaled zanamivir 10 mg daily). The efficacy of oral oseltamivir against symptomatic influenza was 76% (at 75 mg daily), and 73% (at 150 mg daily). Inhaled zanamivir 10 mg daily performed similarly. Neither NI had a significant effect on asymptomatic influenza. Oseltamivir induced nausea (odds ratio (OR) 1.79, 95% CI 1.10 to 2.93). Oseltamivir for post-exposure prophylaxis had an efficacy of 58% and 84% in two trials for households. Zanamivir performed similarly. The hazard ratios for time to alleviation of symptoms were in favour of the treated group 1.20 (1.06 to 1.35) for oseltamivir and 1.24 (1.13 to 1.36) for zanamivir. Because of the exclusion of a review of mainly unpublished trials of oseltamivir, insufficient evidence remained to reach a conclusion on the prevention of complications requiring antibiotics in influenza cases (RR 0.57, 95% CI 0.23 to 1.37). Analysis of the US FDA and Japan's PMDA regulators' pharmacovigilance dataset, revealed incomplete reporting and description of harms preventing us from reaching firm conclusions on the central nervous system toxicity of neuraminidase inhibitors. AUTHORS' CONCLUSIONS: Numerous inconsistencies detected in the available evidence, followed by an inability to adequately access the data, has undermined confidence in our previous conclusions for oseltamivir. Independent RCTs to resolve these uncertainties are needed
