Recent advances in cellular profiling have demonstrated substantial heterogeneity in the behaviour of cells once deemed 'identical', challenging fundamental notions of cell 'type' and 'state'. Not ...surprisingly, these findings have elicited substantial interest in deeply characterizing the diversity, interrelationships and plasticity among cellular phenotypes. To explore these questions, experimental platforms are needed that can extensively and controllably profile many individual cells. Here, microfluidic structures - whether valve-, droplet- or nanowell-based - have an important role because they can facilitate easy capture and processing of single cells and their components, reducing labour and costs relative to conventional plate-based methods while also improving consistency. In this article, we review the current state-of-the-art methodologies with respect to microfluidics for mammalian single-cell 'omics' and discuss challenges and future opportunities.
In recent years, digital technology and wearable devices applied to seizure detection have progressively become available. In this study, we investigated the perspectives of people with epilepsy ...(PWE), caregivers (CG), and healthcare professionals (HP). We were interested in their current use of digital technology as well as their willingness to use wearables to monitor seizures. We also explored the role of factors influencing engagement with technology, including demographic and clinical characteristics, data confidentiality, need for technical support, and concerns about strain or increased workload.
An online survey drawing on previous data collected via focus groups was constructed and distributed via a web link. Using logistic regression analyses, demographic, clinical, and other factors identified to influence engagement with technology were correlated with reported use and willingness to use digital technology and wearables for seizure tracking.
Eighty-seven surveys were completed, fifty-two (59.7%) by PWE, 13 (14.4%) by CG, and 22 (25.3%) by HP. Responders were familiar with multiple digital technologies, including the Internet, smartphones, and personal computers, and the use of digital services was similar to the UK average. Moreover, age and disease-related factors did not influence access to digital technology. The majority of PWE were willing to use a wearable device for long-term seizure tracking. However, only a limited number of PWE reported current regular use of wearables, and nonusers attributed their choice to uncertainty about the usefulness of this technology in epilepsy care. People with epilepsy envisaged the possibility of understanding their condition better through wearables and considered, with caution, the option to send automatic emergency calls. Despite concerns around accuracy, data confidentiality, and technical support, these factors did not limit PWE's willingness to use digital technology. Caregivers appeared willing to provide support to PWE using wearables and perceived a reduction of their workload and anxiety. Healthcare professionals identified areas of application for digital technologies in their clinical practice, pending an appropriate reorganization of the clinical team to share the burden of data reviewing and handling.
Unlike people who have other chronic health conditions, PWE appeared not to be at risk of digital exclusion. This study highlighted a great interest in the use of wearable technology across epilepsy service users, carers, and healthcare professionals, which was independent of demographic and clinical factors and outpaced data security and technology usability concerns.
•Epilepsy service users are interested in the application of wearables in routine care.•Uncertainty about the usefulness of wearable devices limited their current use.•Commonly used, discrete multimodal devices were preferred for long-term use.•An automated device-generated alarm feature should be considered with caution.•Specific epilepsy care team personnel should be dedicated to digital data handling.
Gender bias and discrimination have profound and far-reaching effects on the health care workforce, delivery of patient care, and advancement of science and are antithetical to the principles of ...professionalism. In the quest for gender equity, medicine, with its abundance of highly educated and qualified women, should be leading the way. The sheer number of women who comprise the majority of pediatricians in the United States suggests this specialty has a unique opportunity to stand out as progressively equitable. Indeed, there has been much progress to celebrate for women in medicine and pediatrics. However, many challenges remain, and there are areas in which progress is too slow, stalled, or even regressing. The fair treatment of women pediatricians will require enhanced and simultaneous commitment from leaders in 4 key gatekeeper groups: academic medical centers, hospitals, health care organizations, and practices; medical societies; journals; and funding agencies. In this report, we describe the 6-step equity, diversity, and inclusion cycle, which provides a strategic methodology to (1) examine equity, diversity, and inclusion data; (2) share results with stakeholders; (3) investigate causality; (4) implement strategic interventions; (5) track outcomes and adjust strategies; and (6) disseminate results. Next steps include the enforcement of a climate of transparency and accountability, with leaders prioritizing and financially supporting workforce gender equity. This scientific and data-driven approach will accelerate progress and help pave a pathway to better health care and science.
•Youth are using JUUL as a discreet way to use nicotine in and around school.•JUUL does not appear to be thought of by its users as a cessation device.•Data from social media can serve as an early ...warning system to inform public health.
As vaping rapidly becomes more prevalent, social media data can be harnessed to capture individuals’ discussions of e-cigarette products quickly. The JUUL vaporizer is the latest advancement in e-cigarette technology, which delivers nicotine to the user from a device that is the size and shape of a thumb drive. Despite JUUL’s growing popularity, little research has been conducted on JUUL. Here we utilized Twitter data to determine the public’s early experiences with JUUL describing topics of posts.
Twitter posts containing the term “JUUL” were obtained for 1 April 2107 to 14 December 2017. Text classifiers were used to identify topics in posts (n = 81,689).
The most prevalent topic wasPerson Tagging (use of @username to tag someone in a post) at 20.48% followed by Pods (mentions of JUUL’s refill cartridge) at 14.72% and Buying (mentions of purchases) at 10.49%. The topic School (posts indicative of using JUUL or seeing someone use JUUL while at elementary, middle, or high school) comprised 3.66% of posts. The topic of Quit Smoking was rare at 0.29%.
Data from social media may be used to extend the surveillance of newly introduced vaping products. Findings suggest Twitter users are bonding around, and inquiring about, JUUL on social media. JUUL’s discreetness may facilitate its use in places where vaping is prohibited. Educators may be in need of training on how to identify JUUL in the classroom. Despite JUUL’s branding as a smoking alternative, very few Twitter users mentioned smoking cessation with JUUL.
•Understanding the existing drug repositioning methods with a top-down flowchart.•Prioritizing repositioning methods using their integrated knowledge and information.•A general drug-repositioning ...pipeline with a fishbone flowchart.•Guidance for customizing and generating new drug-repositioning pipelines.
Recycling old drugs, rescuing shelved drugs and extending patents’ lives make drug repositioning an attractive form of drug discovery. Drug repositioning accounts for approximately 30% of the newly US Food and Drug Administration (FDA)-approved drugs and vaccines in recent years. The prevalence of drug-repositioning studies has resulted in a variety of innovative computational methods for the identification of new opportunities for the use of old drugs. Questions often arise from customizing or optimizing these methods into efficient drug-repositioning pipelines for alternative applications. It requires a comprehensive understanding of the available methods gained by evaluating both biological and pharmaceutical knowledge and the elucidated mechanism-of-action of drugs. Here, we provide guidance for prioritizing and integrating drug-repositioning methods for specific drug-repositioning pipelines.
Pediatricians are an important source of health care for adolescents and young adults and can play a significant role in addressing their patients' sexual and reproductive health needs, including ...preventing unintended pregnancies and sexually transmitted infections (STIs), including HIV, and promoting healthy relationships. STIs, HIV, and unintended pregnancy are all preventable health outcomes with potentially serious permanent sequelae; the highest rates of STIs, HIV, and unintended pregnancy are reported among adolescents and young adults. Office visits present opportunities to provide comprehensive education and health care services to adolescents and young adults to prevent STIs, HIV, and unintended pregnancies. The American Academy of Pediatrics, other professional medical organizations, and the government have guidelines and recommendations regarding the provision of sexual and reproductive health information and services. However, despite these recommendations, recent studies have revealed that there is substantial room for improvement in actually delivering the recommended services. The purpose of this clinical report is to assist pediatricians to operationalize the provision of various aspects of sexual and reproductive health care into their practices and to provide guidance on overcoming barriers to providing this care routinely while maximizing opportunities for confidential health services delivery in their offices.
Background
There are sparse clinical data on the procedural trends, outcomes and readmission rates following FDA approval and expansion of Transcatheter mitral valve repair/MitraClip®. Whether a ...complex new technology can be disseminated safely and quickly is controversial.
Methods
The study cohort was derived from the National Readmission Data (NRD) 2013–14. MitraClip® was identified using appropriate International Classification of Diseases, 9th Revision, Clinical Modification (ICD‐9‐CM) codes. The primary outcome was a composite of in‐hospital mortality + procedural complications. Secondary outcome included 30‐day readmissions. Hierarchical two level logistic models were used to evaluate study outcomes.
Results
Our analysis included 2003 MitraClip® procedures. Overall in‐hospital mortality was 3.9%. As expected, there was a significant increase in procedural volume post‐FDA approval. Importantly, a corresponding downward trend in mortality and procedural complications was observed. Significant predictors of in‐hospital mortality and procedural complications included the use of vasopressors (P <0.001) and hemodynamic support (P < 0.001). Higher hospital volume (≥10 MitraClips/year) was associated with lower in‐hospital mortality and complications (P = 0.02). There were 304 (15.1%) 30‐day readmissions, with heart failure being the most common cause of readmission. Elective procedures had lower in‐hospital mortality (P < 0.001) and lower readmission rates (P = 0.011) compared with nonelective procedures.
Conclusion
A significant increase in MitraClip® procedural volumes occurred post‐FDA approval. Overall morbidity and mortality were low and trended downwards. Hospital procedure volume ≥10 cases were associated with lower mortality and overall complication rates. These data suggest a successful roll out of a very complex novel structural heart procedure.
Background:
The creation and maintenance of dialysis vascular access is associated with significant morbidity. Structured management pathways can reduce this morbidity, yet practice patterns in ...Australia and New Zealand are not known. We aimed to describe the arteriovenous access practices in dialysis units in Australia and New Zealand.
Methods:
An online survey comprising 51 questions was completed by representatives from dialysis units from both countries. In addition to descriptive analysis, responses were compared between units inside and outside of major cities.
Results:
Of 64 contacted units, 48 (75%) responded (Australia 43, New Zealand 5), representing 38% of dialysis units in Australia and New Zealand. While 94% of units provided pre-dialysis education, only 60% reported a structured pre-dialysis pathway and 69% had a dedicated vascular access nurse. Most units routinely monitored fistula/graft function using flow rate measurement (73%) or recirculation studies (63%). A minority used routine ultrasound (35%). Thrombectomy, fistuloplasty and peritoneal dialysis catheter insertion were rarely performed by nephrologists (4%, 4% and 17% of units, respectively). Units outside of a major city were less likely to have access to a local vascular access surgeon (6/13 (46%) vs 35/35 (100%), P < 0.001). There were no other significant differences between units on the basis of location.
Conclusion:
Much variation exists in unit management of arteriovenous access. Structured pre-dialysis pathways and dedicated vascular access nurses may be underutilised in Australia and New Zealand. The use of regular access blood flow measurement and ultrasound is common in both countries despite a lack of data supporting its effectiveness. There is room for both practice improvement and a need for further evidence to ensure optimal arteriovenous access care.
