The respiratory microbiome after lung transplantation: Reflection or driver of respiratory disease?

With the introduction of high-throughput sequencing methods, our understanding of the human lower respiratory tract's inhabitants has expanded significantly in recent years. What is now termed the “lung microbiome” has been described for healthy patients, as well as people with chronic lung diseases and lung transplants. The lung microbiome of lung transplant recipients (LTRs) has proven to be unique compared with nontransplant patients, with characteristic findings associated with disease states, such as pneumonia, acute rejection, and graft failure. In this review, we summarize the current understanding of the lung microbiome in LTRs, not only focusing on bacteria but also highlighting key findings of the viral and the fungal community. Based on our knowledge of the lung microbiome in LTRs, we propose multiple opportunities for clinical use of the microbiome to improve outcomes in this population.     

Factors influencing routine cognitive impairment screening in older at-risk drinkers: Findings from a qualitative study in the United Kingdom

Cognitive Impairment (CI) screening is recommended for those engaged in harmful levels of alcohol use. However, there is a lack of evidence on implementation. This paper explores the barriers and facilitators to CI screening experienced across a service specifically for older drinkers. The findings draw on data gathered as part of an evaluation of a multilevel programme to reduce alcohol-related harm in adults aged 50 and over in five demonstration areas across the United Kingdom. It is based on qualitative interviews and focus groups with 14 service providers and 22 service users. Findings are presented thematically under the section headings: acceptability of screening, interpretation and making sense of screening and treatment options. It is suggested that engagement with CI screening is most likely when its fit with agency culture and its purpose is clear; where service providers have the technical skills to administer and discuss the results of screening with service users; and where those undertaking screening have had the opportunity to reflect on their own experience of being screened. Engagement with CI screening is also most likely where specific intervention pathways and engagement practices can be accessed to respond to assessed need.     

Cardiovascular Effects of Medical Marijuana: A Systematic Review

Utilization of marijuana as a medicinal agent is becoming increasingly popular, and so far, 25 states have legalized it for medical purposes. However, there is emerging evidence that marijuana use can result in cardiovascular side effects, such as rhythm abnormalities, syncope/dizziness, and myocardial infarction, among others. Further, there are currently no stringent national standards or approval processes, like Food and Drug Administration (FDA) evaluation, in place to assess medical marijuana products. This review includes the largest up-to-date pooled population of patients with exposure to marijuana and reported cardiovascular effects. Although purported as benign by many seeking to advance the use of marijuana as an adjunctive medical therapy across the country, marijuana is associated with its own set of cardiovascular risks and deserves further definitive study and the same level of scrutiny we apply in research of all other types of medications. When used as a medicinal agent, marijuana should be regarded accordingly, and both clinical providers and patients must be aware of potential adverse effects associated with its use for early recognition and management.     

11p15 duplication and 13q34 deletion with Beckwith–Wiedemann syndrome and factor VII deficiency

Here we report a patient with 11p15.4p15.5 duplication and 13q34 deletion presenting with Beckwith–Wiedemann syndrome (BWS) and moderate deficiency of factor VII (FVII). The duplication was initially diagnosed on methylation‐sensitive multiplex ligation‐dependent probe amplification. Array comparative genome hybridization confirmed its presence and indicated a 13q34 distal deletion. The patient's clinical symptoms, including developmental delay and facial dysmorphism, were typical of BWS with paternal 11p15 trisomy. Partial 13q monosomy in this patient is associated with moderate deficiency of FVII and may also overlap with a few symptoms of paternal 11p15 trisomy such as developmental delay and some facial features. To our knowledge this is the first report of 11p15.4p15.5 duplication associated with deletion of 13q34 and FVII deficiency. Moreover, this report emphasizes the importance of detailed clinical as well as molecular examinations in patients with BWS features and developmental delay.     

An analysis of the first implementation and impact of the World Health Organisation’s health promoting school model within disadvantaged city schools in Ireland

While knowledge about the World Health Organisation’s (WHO) healthy schools model has been developed in recent years, process implementation and outcomes for school children have not improved in line with these advances. This deficit has become known as the ‘implementation gap’ and refers to the difference between the evidence of what works in theory and what is delivered in practice. The aim of this research was to evaluate the first implementation and impact of the WHO model among urban disadvantaged school children in Ireland from 2008 to 2012. A concurrent mixed methods study design was used. A process evaluation-mapped implementation and a three-year cohort study measured the impact. Data comprised of semi-structured interviews, focus groups and documentary analysis. Instruments included the Kidscreen-27 and the Child Depression Inventory (CDI). Over 600 children in five intervention and two comparison schools were recruited. The process evaluation revealed that top-down decision making based on the communities rather than each individual school’s needs and a lack of understanding of the concept of the whole school approach inhibited implementation. No significant differences were found between intervention and comparison of schools over three years post implementation. The successful implementation within an urban disadvantaged region requires not an analysis of the regional needs but a development of the individual school needs and sufficient lead-in time to ensure that each school is ready in terms of its understanding. Furthermore, healthy schools coordinators roles need to be clarified as facilitators of development and change rather than as unsustainable providers of health activities.
