Based on the definition by the WHO from 1998, palliative care for children is the active, total care of the childs body, mind and spirit, and involves giving care to the family. It begins when the illness is diagnosed and continues regardless of whether a child receives treatment directed at the disease. The World Health Organization (WHO) definition of pediatric palliative care was adopted by IMPaCCT (International Meeting for Palliative Care in Children, Trento) and became the key point of document, which defines and determines standards for care of children with life-limiting and life-threatening disease and recommends that these standards should be implemented in all European countries...

Despite the advances in dialysis technology over the past decades, patients with advanced chronic kidney disease (CKD) have a high symptom burden, shortened survival and substantial physical, emotional and spiritual suffering. Number of frailty patients with advanced chronic kidney disease is growing and for many of them the beginning or continuation of dialysis is associated with a high risk of short-term mortality or worsening of functional status. Identifying these fragile patients and integrating palliative care into standard nephrological care improves patients quality of life and has the potential to prolong their lives without demanding dialysis treatment...

Chronic heart failure is a progressive disease with an increasing prevalence. In spite of all medical progress (or thanks to it), it is finally one of the most common causes of death. Palliative care is an approach aimed to improve the quality of life of patients and their families in cases of life-threatening illness. Therefore, the use of palliative care in cardiology is entirely relevant. Estimating the course and prognosis of a patient with chronic heart failure is difficult despite many prognostic tools...

Water analysis has been an important area since the beginning of analytical chemistry. The focus though has shifted substantially: from minerals and the main constituents of water in the time of Carl Remigius Fresenius to a multitude of, in particular, organic compounds at concentrations down to the sub-nanogram per liter level nowadays. This was possible only because of numerous innovations in instrumentation in recent decades, drivers of which are briefly discussed. In addition to the high demands on sensitivity, high throughput by automation and short analysis times are major requirements...

Isolated landscapes largely shaped by aeolian processes can occur on Earth, while the majority of Mars' recent history has been dominated by wind-driven activity. Resultantly, Martian landscapes often exhibit large-scale aeolian features, including yardang landforms carved from sedimentary-layered deposits. High-resolution orbital monitoring has revealed that persistent bedform activity is occurring with dune and ripple migration implying ongoing abrasion of the surface. However, little is known about the interaction between dunes and the topography surrounding them...

Diagnosing vertical root fracture (VRF) is difficult. Here, we retrospectively investigated the duration from initial symptoms to a definite diagnosis of VRF in dental offices. Data were collected on patients with VRF between July 2013 and June 2015. Initial symptoms were ascertained from clinical records. The focus was on the maxillary second premolars and mesial roots of the mandibular first molars, where VRF is most frequent. All VRF in the bilateral dentition was analyzed. Only cases in which the buccal-lingual plane of the root was fractured were included...

While the treatment of inflammatory disorders is generally based on inhibiting factors that drive onset of inflammation, these therapies can compromise healing (NSAIDs) or dampen immunity against infections (biologics). In search of new antiinflammatories, efforts have focused on harnessing endogenous pathways that drive resolution of inflammation for therapeutic gain. Identification of specialized pro-resolving mediators (SPMs) (lipoxins, resolvins, protectins, maresins) as effector molecules of resolution has shown promise in this regard...

Miscible liquids can phase separate in response to a composition change. In bulk fluids, the demixing begins on molecular-length scales, which coarsen into macroscopic phases. By contrast, confining a mixture in microfluidic droplets causes sequential phase separation bursts, which self-organize into rings of oil and water to make multilayered emulsions. The spacing in these nonequilibrium patterns is self-similar and scale-free over a range of droplet sizes. We develop a modified Cahn-Hilliard model, in which an immiscibility front with stretched exponential dynamics quantitatively predicts the spacing of the layers...

BACKGROUND: Grip strength in early adulthood and midlife is an important predictor of disability, morbidity and mortality in later life. Understanding social patterning in grip strength at different life stages could improve insight into inequalities in age-related decline and when in the life course interventions could prevent the emergence of inequalities. METHODS: Using United Kingdom Household Longitudinal Study (UKHLS) data on 19,292 people aged 16 to 99, fractional polynomial models were fitted to identify which function of age best described its association with grip strength...

BK polyomavirus (BKPyV; hereafter referred to as BK) causes a lifelong chronic infection and is associated with debilitating disease in kidney transplant recipients. Despite its importance, aspects of the virus life cycle remain poorly understood. In addition to the structural proteins, the late region of the BK genome encodes for an auxiliary protein called agnoprotein. Studies on other polyomavirus agnoproteins have suggested that the protein may contribute to virion infectivity. Here, we demonstrate an essential role for agnoprotein in BK virus release...
