Epidemiology, Patterns of Care, and Mortality for Patients With Acute Respiratory Distress Syndrome in Intensive Care Units in 50 Countries

Importance Limited information exists about the epidemiology, recognition, management, and outcomes of patients with the acute respiratory distress syndrome (ARDS).

Objectives To evaluate intensive care unit (ICU) incidence and outcome of ARDS and to assess clinician recognition, ventilation management, and use of adjuncts—for example prone positioning—in routine clinical practice for patients fulfilling the ARDS Berlin Definition.

Design, Setting, and Participants The Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE) was an international, multicenter, prospective cohort study of patients undergoing invasive or noninvasive ventilation, conducted during 4 consecutive weeks in the winter of 2014 in a convenience sample of 459 ICUs from 50 countries across 5 continents.

Exposures Acute respiratory distress syndrome.

Main Outcomes and Measures The primary outcome was ICU incidence of ARDS. Secondary outcomes included assessment of clinician recognition of ARDS, the application of ventilatory management, the use of adjunctive interventions in routine clinical practice, and clinical outcomes from ARDS.

Results Of 29 144 patients admitted to participating ICUs, 3022 (10.4%) fulfilled ARDS criteria. Of these, 2377 patients developed ARDS in the first 48 hours and whose respiratory failure was managed with invasive mechanical ventilation. The period prevalence of mild ARDS was 30.0% (95% CI, 28.2%-31.9%); of moderate ARDS, 46.6% (95% CI, 44.5%-48.6%); and of severe ARDS, 23.4% (95% CI, 21.7%-25.2%). ARDS represented 0.42 cases per ICU bed over 4 weeks and represented 10.4% (95% CI, 10.0%-10.7%) of ICU admissions and 23.4% of patients requiring mechanical ventilation. Clinical recognition of ARDS ranged from 51.3% (95% CI, 47.5%-55.0%) in mild to 78.5% (95% CI, 74.8%-81.8%) in severe ARDS. Less than two-thirds of patients with ARDS received a tidal volume 8 of mL/kg or less of predicted body weight. Plateau pressure was measured in 40.1% (95% CI, 38.2-42.1), whereas 82.6% (95% CI, 81.0%-84.1%) received a positive end-expository pressure (PEEP) of less than 12 cm H2O. Prone positioning was used in 16.3% (95% CI, 13.7%-19.2%) of patients with severe ARDS. Clinician recognition of ARDS was associated with higher PEEP, greater use of neuromuscular blockade, and prone positioning. Hospital mortality was 34.9% (95% CI, 31.4%-38.5%) for those with mild, 40.3% (95% CI, 37.4%-43.3%) for those with moderate, and 46.1% (95% CI, 41.9%-50.4%) for those with severe ARDS.

Conclusions and Relevance Among ICUs in 50 countries, the period prevalence of ARDS was 10.4% of ICU admissions. This syndrome appeared to be underrecognized and undertreated and associated with a high mortality rate. These findings indicate the potential for improvement in the management of patients with ARDS.

A comparison of endoscopy versus pathology sizing of colorectal adenomas and potential implications for surveillance colonoscopy

Background and AimsTo compare endoscopy and pathology sizing in a large population-based series of colorectal adenomas and to evaluate the implications for patient stratification into surveillance colonoscopy.MethodsEndoscopy and pathology sizes available from intact adenomas removed at colonoscopies performed as part of the Northern Ireland Bowel Cancer Screening Programme, from 2010 to 2015, were included in this study. Chi-squared tests were applied to compare size categories in relation to clinicopathological parameters and colonoscopy surveillance strata according to current American Gastroenterology Association and British Society of Gastroenterology guidelines.ResultsA total of 2521 adenomas from 1467 individuals were included. There was a trend toward larger endoscopy than pathology sizing in 4 of the 5 study centers, but overall sizing concordance was good. Significantly greater clustering with sizing to the nearest 5 mm was evident in endoscopy versus pathology sizing (30% vs 19%, p<0.001), which may result in lower accuracy. Applying a 10-mm cut-off relevant to guidelines on risk stratification, 7.3% of all adenomas and 28.3% of those 8 to 12 mm in size had discordant endoscopy and pathology size categorization. Depending upon which guidelines are applied, 4.8% to 9.1% of individuals had differing risk stratification for surveillance recommendations, with the use of pathology sizing resulting in marginally fewer recommended surveillance colonoscopies.ConclusionsChoice of pathology or endoscopy approaches to determine adenoma size will potentially influence surveillance colonoscopy follow-up in 4.8% to 9.1% of individuals. Pathology sizing appears more accurate than endoscopy sizing, and preferential use of pathology size would result in a small, but clinically important, decreased burden on surveillance colonoscopy demand. Careful endoscopy sizing is required for adenomas removed piecemeal.

“I just can’t, I am frightened for my safety, I don’t know how to work with her” Practitioners’ experiences of client violence and recommendations for future practice

To what extent is the therapist-client relationship damaged following client perpetuated violence and what steps can we take to diminish its impact? Much of the information we have on client violence comes from multiple mental health disciplines in the US and the UK over the last 20-30 years and has formed a useful, though sometimes dated and sporadic, quantitative baseline to delineate a range of issues. However, there is limited systematic research on how practitioner psychologists process the violence in the course of their everyday practice and how this impacts the therapist-client dynamic. Using Interpretative Phenomenological Analysis (IPA), we explored seven therapists’ experiences of client violence across a range of work sites – acute psychiatric hospital wards, forensic hospital wards and community mental health teams. Three main themes were documented: processing the moment-to-moment experience of client violence; professional vulnerabilities and needs as a result of client violence; and the ruptured therapeutic relationship. Strategies for supporting practicing psychologists and providing continuing professional care for clients include challenging self-doubt and re-energizing professional competencies as well as repairing ourselves and repairing the therapeutic relationship. Recommendations for credentialing and regulatory bodies in relation to client violence are also highlighted.

Digital Technologies and the Museum Experience

This co-edited book focuses on core theories and research on technologies, from the first audio guides to contemporary and future mobile digital devices, which inform practical design considerations. It is framed in case studies and focuses generally on informal learning by museum and gallery visitors. The book fills a significant gap in the literature on museum practice with regard to uses of digital technologies, which are not generally grounded in rigorous research, and is intended to retain its relevance as technologies evolve and emerge. The book includes chapters by invited authors from the USA, UK and Europe who contribute expertise in a number of areas of museum research and practice. The research resulted in invited keynote speeches in France (‘Technologie de l’apprentissage humain dans les musées’ seminar at Laboratoire d’Informatique de Grenoble on 5 March 2009), Iceland (keynote at ‘NODEM Network of Design and Digital Heritage’ conference on 3 December 2008) and London (Keynote at ‘Mobile Learning Conference’ on 26 January 2009). The book was given the highest recommendation ('Essential') by the American Library Association, and was reviewed in MedieKultur (2011, 50, 185–92). Walker’s chapter includes some of the initial findings from his PhD research on visitor-constructed trails in museums, which shifts focus from the design of technologies to the design of activities intended to structure the use of technologies, and constitutes some of the first published research on visitor-generated trails using mobile technologies. Structures such as trails are shown to act as effective mental models for museum visitors, especially structures with a narrow subject focus and manageable amount of data capture; those created as a narrative or a conversation; and those that emphasise construction, rather than data capture. Walker also selected most of the other chapter authors, suggested their topics and led the editing of the publication.

Le rapport à la formation infirmière continue chez des infirmières en soutien à domicile

Les changements dans le réseau de la santé tel que le virage des soins vers le soutien à domicile (SAD) pour les aînés en perte d'autonomie, exigent des infirmières qu'elles mettent à jour leurs connaissances. Cette étude qualitative réalisée au moyen d'entrevues semi-dirigées s'intéresse au rapport à la formation infirmière continue (FIC) chez des infirmières en SAD au Québec. Son cadre de référence s'inspire des modèles de l'American Nurses Association (1994), de Cervero (1985) et de Hegge (1985). Les résultats révèlent que les infirmières sont engagées en FIC, qu'elles réalisent des activités de formation continue (AFC) diversifiées et qu'elles perçoivent certaines retombées dans leur pratique clinique. Cependant, des contraintes de temps, de coûts et d'accessibilité des AFC pertinentes demeurent des enjeux à prendre en considération. Finalement, des recommandations concernant la pratique clinique, l'enseignement, la gestion et la recherche sont proposées.

Effet ajouté et participation des pères à un programme d'entraînement aux habiletés parentales

Selon l'American Psychiatric Association (APA, 2004), les troubles du comportement perturbateur (TCP) se divisent en trois diagnostics : le trouble d'attention avec ou sans hyperactivité (TDA/H), le trouble d'opposition avec ou sans provocation (TOP) et le trouble des conduites (TC). Les programmes d'entraînement aux habiletés parentales (PEHP) sont reconnus comme étant des pratiques probantes dans le traitement de ces troubles (Hartman, Stage et Webster-Stratton, 2003; Kazdin, 2001; Nock & Kazdin, 2001; Webster-Stratton, 2007; Weersing & Weisz, 2000). Toutefois, les pères s'impliquent généralement moins que les mères dans ce type d'intervention alors que leur implication dans la vie de l'enfant est associée à de nombreux bénéfices (Coplin & Houts, 1991; Lamb, 2004). Les objectifs de cette étude sont de vérifier si la participation des pères au programme est similaire à celle des mères et de vérifier quel est l'effet ajouté de leur participation à l'efficacité d'un PEHP sur l'enfant, les parents et la famille. Au total, 33 familles ont participé au programme et leur présence est justifiée par le TDA/H de leur enfant. Le groupe "sans père" (SP) est formé de 9 mères qui sont venues seules aux rencontres et le groupe "avec pères" (AP) est formé de 24 pères et mères venus ensemble. Ils ont participé au programme Ces années incroyables qui inclut 16 rencontres de groupe de deux heures chacune. L'évaluation est faite avant le programme (pré-test, Tl), à la fin (post-test, T2) et 6 mois plus tard (suivi, T3) et inclut des mesures du comportement de l'enfant, des pratiques éducatives parentales, du stress parental, du sentiment d'autoefficacité parental et du fonctionnement familial. Les résultats démontrent que les pères accompagnés sont moins assidus que les mères accompagnées, mais ne se distinguent pas des mères qui sont venues seules. Leur engagement dans les rencontres est toutefois similaire à celui des mères. Les analyses de variance à mesures répétées démontrent une amélioration plus immédiate des comportements extériorisés chez l'enfant dont le père était présent au programme. Suite au programme (post-test), sa présence n'a pas d'effet sur le stress parental, mais six mois après la fin de ce dernier (suivi), les mères qui y étaient seules se sentent plus stressée [i.e. stressées] que celles qui étaient accompagnées du père. Toutefois, très peu d'effets ont été décelés sur les pratiques éducatives parentales et le fonctionnement familial. La discussion analyse ces résultats et y fait suivre des retombées cliniques.

Should cash transfer be conditional? Condition, preventive care, and health outcomes

We study a Conditional Cash Transfer program in which the cash transfers to the mother only depends on the fulfillment of the national preventive visit schedule by her children born before she registered in the program. We estimate that preventive visits of children born after the mother registered in the program are 50% lower because they are excluded from the conditionality requirement. Using the same variation, we also show that attendance to preventive care improves children's health.

The effects of parental sensitivity and involvement in caregiving on mother–infant and father–infant attachment in a portuguese sample

In the present longitudinal study, we investigated attachment quality in Portuguese mother–infant and in father–infant dyads, and evaluated whether attachment quality was related to parental sensitivity during parent–infant social interaction or to the amount of time each parent spent with the infant during play and in routine caregiving activities (e.g., feeding, bathing, play). The sample consisted of 82 healthy full-term infants (30 girls, 53 boys, 48 first born), and their mothers and fathers from mostly middle-class households. To assess parental sensitivity, mothers and fathers were independently observed during free play interactions with their infants when infants were 9 and 15 months old. The videotaped interactions were scored by masked coders using the Crittenden’s CARE-Index. When infants were 12 and 18 months old, mother–infant and father–infant dyads were videotaped during an adaptation of Ainsworth’s Strange Situation. Parents also described their level of involvement in infant caregiving activities using a Portuguese version of the McBride and Mills Parent Responsibility Scale. Mothers were rated as being more sensitive than fathers during parent–infant free play at both 9 and 15 months. There also was a higher prevalence of secure attachment in mother–infant versus father–infant dyads at both 12 and 18 months. Attachment security was predicted by the amount of time mothers and fathers were involved in caregiving and play with the infant, and with parents’ behavior during parent–infant free play.

Long-term miR-669a therapy alleviates chronic dilated cardiomyopathy in dystrophic mice.

BACKGROUND: Dilated cardiomyopathy (DCM) is a leading cause of chronic morbidity and mortality in muscular dystrophy (MD) patients. Current pharmacological treatments are not yet able to counteract chronic myocardial wastage, thus novel therapies are being intensely explored. MicroRNAs have been implicated as fine regulators of cardiomyopathic progression. Previously, miR-669a downregulation has been linked to the severe DCM progression displayed by Sgcb-null dystrophic mice. However, the impact of long-term overexpression of miR-669a on muscle structure and functionality of the dystrophic heart is yet unknown. METHODS AND RESULTS: Here, we demonstrate that intraventricular delivery of adeno-associated viral (AAV) vectors induces long-term (18 months) miR-669a overexpression and improves survival of Sgcb-null mice. Treated hearts display significant decrease in hypertrophic remodeling, fibrosis, and cardiomyocyte apoptosis. Moreover, miR-669a treatment increases sarcomere organization, reduces ventricular atrial natriuretic peptide (ANP) levels, and ameliorates gene/miRNA profile of DCM markers. Furthermore, long-term miR-669a overexpression significantly reduces adverse remodeling and enhances systolic fractional shortening of the left ventricle in treated dystrophic mice, without significant detrimental consequences on skeletal muscle wastage. CONCLUSIONS: Our findings provide the first evidence of long-term beneficial impact of AAV-mediated miRNA therapy in a transgenic model of severe, chronic MD-associated DCM.

Elevated blood pressure prevalence in children did not follow the increase in overweight: results from a school-based study in a rapidly developing country, 1998-2006

Background: Blood pressure (BP) is strongly associated with body weight and there is concern that the pediatric overweight epidemic could lead to an increase in children's mean BP. Objectives: We analyzed BP trends from 1998 to 2006 among children of the Seychelles, a rapidly developing middle-income country in Africa. Methods: Serial school-based surveys of weight, height and BP were conducted yearly between 1998-2006 among all students of the country in four school grades (kindergarten, 4th, 7th and 10th years of compulsory school). We used the CDC criteria to define "overweight" (BMI _95th sex-, and age-specific percentile) and the NHBPEP criteria for "elevated BP" (BP _95th sex-, age-, and height specific percentile). Methods for height, weight, and BP measurements were identical over the study period. The trends in mean BMI and mean systolic/diastolic BP were assessed with linear regression. Results: 27,703 children aged 4-18 years (participation rate: 79%) contributed 43,927 observations on weight, height, and BP. The prevalence of overweight increased from 5.1% in 1998-2000 to 8.1% in 2004-2006 among boys, and from 6.1% to 9.1% among girls, respectively. The prevalence of elevated BP was 8.4% in 1998-2000 and 6.9% in 2004-2006 among boys; 9.8% and 7.8% among girls, respectively. Over the 9-years study period, age-adjusted body mass index (BMI) increased by 0.078 kg/m2/year in boys and by 0.083 kg/m2/year in girls (both sexes, P_0.001). Age- and height-adjusted systolic BP decreased by -0.37 mmHg/year in boys and by -0.34 mmHg/year in girls (both sexes, P_0.001). Diastolic BP did not change in boys (-0.02 mmHg/year, P: 0.40) and slightly increased in girls (0.07 mmHg/year, P: 0.003). These trend estimates were altered modestly upon further adjustment for BMI or if analyses were based on median rather than mean values. Conclusion: Although body weight increased markedly between 1998 and 2006 in this population, systolic BP decreased and diastolic BP changed only marginally. This suggests that population increases in body weight are not necessarily associated with corresponding rises in BP in children.
