Cystic fibrosis (CF) is the major genetic inherited disease in Caucasian populations. The respiratory tract of CF patients displays a sticky viscous mucus, which allows for the entrapment of airborne bacteria and fungal spores and provides a suitable environment for growth of microorganisms, including numerous yeast and filamentous fungal species. As a consequence, respiratory infections are the major cause of morbidity and mortality in this clinical context. Although bacteria remain the most common agents of these infections, fungal respiratory infections have emerged as an important cause of disease...

BACKGROUND: TKA pain management protocols vary widely with no current consensus on a standardized pain management regimen. Multimodal TKA pain management protocols aim to address pain control, facilitate functional recovery, and maintain patient satisfaction. QUESTIONS/PURPOSES: (1) Did changes to our pain management protocol, specifically adding liposomal bupivacaine, eliminating patient-controlled analgesia (PCA), and discontinuing femoral nerve blocks (FNBs), affect narcotic consumption after TKA? (2) Did these changes to our pain management protocols affect patient-reported pain scores? (3) Does the use of an immediate postoperative PCA affect rapid rehabilitation and functional recovery? (4) How did changes to our pain management regimen affect discharge disposition and pain-related Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores? METHODS: We retrospectively analyzed an institutional arthroplasty database between September 2013 and September 2015 containing 1808 patients who underwent primary TKA...

Patients suffering from neuronal degenerative diseases are increasingly being equipped with neural implants to treat symptoms or restore functions and increase their quality of life. Magnetic resonance imaging (MRI) would be the modality of choice for diagnosis and compulsory post-operative monitoring of such patients. However, interactions between the MR environment and implants pose severe health risks to the patient. Nevertheless, neural implant recipients regularly underwent MRI examinations, and adverse events were reported rarely...

BACKGROUND: Non-steroidal anti-inflammatory drug use has been shown to increase blood pressure in non-pregnant adults. Because of this, the American College of Obstetricians and Gynecologists suggests avoiding their use in women with postpartum hypertension; however, evidence to support this recommendation is lacking. OBJECTIVES: Our goal was to test the hypothesis that non-steroidal anti-inflammatory drugs, such as ibuprofen, adversely affect postpartum blood pressure control in women with preeclampsia with severe features...

From the war on drug resistance, through cancer biology, even to agricultural and environmental protection: there is a huge demand for rapid and effective solutions to control infections and diseases. The development of small molecule inhibitors was once an accepted "one-size fits all" approach to these varied problems, but persistence and resistance threaten to return society to a pre-antibiotic era. Only five essential cellular targets in bacteria have been developed for the majority of our clinically-relevant antibiotics...

The social gradient for cardiovascular disease (CVD) onset and outcomes is well established. The American Heart Association's Social Determinants of Risk and Outcomes of Cardiovascular Disease Scientific Statement advocates looking beyond breakthroughs in biological science toward a social determinants approach that focuses on socioeconomic position, race and ethnicity, social support, culture and access to medical care, and residential environments to curb the burden of CVD going forward. Indeed, the benefits of this approach are likely to be far reaching, enhancing the positive effects of advances in CVD related to prevention and treatment while reducing health inequities that contribute to CVD onset and outcomes...

The US National Academy of Sciences has called for the development of a Learning Healthcare System in which patients and clinicians work together to choose care, based on best evidence, and to drive discovery as a natural outgrowth of every clinical encounter to ensure innovation, quality and value at the point of care. However, the vision of a Learning Healthcare System has remained largely aspirational. Over the last 13 years, researchers, clinicians and families, with support from our paediatric medical centre, have designed, developed and implemented a network organisational model to achieve the Learning Healthcare System vision...

Nerve and muscle signalling is controlled by voltage-gated sodium (Nav) channels which are the targets of local anesthetics, anti-epileptics and anti-arrythmics. Current medications do not selectively target specific types of Nav found in the body, but compounds that do so have the potential to be breakthrough treatments for chronic pain, epilepsy and other neuronal disorders. We use long computer simulations totaling more than 26 μs to show how a promising lead compound can target one Nav implicated in pain perception and specific channels found in bacteria, and accurately predict the affinity of the compound to different channel types...

Medical management of caries is a distinct treatment philosophy that employs topical minimally invasive therapies that treat the disease and is not merely prevention. This strategy is justified as an alternative or supplement to traditional care by significant disease recurrence rates following comprehensive operative treatment under general anesthesia. Silver diamine fluoride (SDF) is one agent to enable effective noninvasive treatment. The announcement of breakthrough therapy designation by the Food and Drug Administration (FDA) suggests that SDF may become the first FDA-approved drug for treating caries...
