INTRODUCTION: Low-dose computed tomography (LDCT) lung cancer screening is recommended in the United States. While new solid nodules after baseline screening have a high lung cancer probability at small size and require lower size cutoff values than baseline nodules, there only is limited evidence on management of new subsolid nodules. METHODS: Within the Dutch-Belgian randomized controlled LDCT lung cancer screening trial (NELSON), 7557 participants underwent baseline screening between April 2004 and December 2006...

Cell survival to replication stress depends on the activation of the Mec1ATR -Rad53 checkpoint response that protects the integrity of stalled forks and controls the origin firing program. Here we found that Mad2, a member of the spindle assembly checkpoint (SAC), contributes to efficient origin firing and to cell survival in response to replication stress. We show that Rad53 and Mad2 promote S-phase cyclin expression through different mechanisms: while Rad53 influences Clb5,6 degradation, Mad2 promotes their protein synthesis...

To realize carriers for drug delivery, cationic containers are required for anionic guests. Nevertheless, the toxicity of cationic carriers limits their practical use. In this study, we investigate a model system of polyampholyte N-isopropylacrylamide (NIPAM)-based microgels with a cationic core and an anionic shell to study whether the presence of a negative shell allows the cationic core to be shielded while still enabling the uptake and release of the anionic guest polyelectrolytes. These microgels are loaded with polystyrene sulfonate of different molecular weights to investigate the influence of their chain length on the uptake and release process...

Limbic encephalitis is commonly regarded as an autoimmune-mediated disease. However, after the recent detection of zoonotic variegated squirrel bornavirus 1 in a Prevost's squirrel (Callosciurus prevostii) in a zoo in northern Germany, we retrospectively investigated a fatal case in an autoantibody-seronegative animal caretaker who had worked at that zoo. The virus had been discovered in 2015 as the cause of a cluster of cases of fatal encephalitis among breeders of variegated squirrels (Sciurus variegatoides) in eastern Germany...

The physical behavior of glass-forming liquids presents complex features of both dynamic and thermodynamic nature. Some studies indicate the presence of thermodynamic anomalies and of crossovers in the dynamic properties, but their origin and degree of universality is difficult to assess. Moreover, conventional simulations are barely able to cover the range of temperatures at which these crossovers usually occur. To address these issues, we simulate the Kob-Andersen Lennard-Jones mixture using efficient protocols based on multi-CPU and multi-GPU parallel tempering...

Background: Duchenne muscular dystrophy (DMD) causes progressive pathologic changes to muscle secondary to a cascade of inflammation, lipid deposition, and fibrosis. Clinically, this manifests as progressive weakness, functional loss, and premature mortality. Though insult to whole muscle groups is well established, less is known about the relationship between intramuscular pathology and function. Objective: Differences of intramuscular heterogeneity across muscle length were assessed using an ordinal MRI grading scale in lower leg muscles of boys with DMD and correlated to patient's functional status...

Background: Peripheral blood-derived inflammation-based markers, such as Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Fibrinogen have been identified as prognostic markers in various solid malignancies. Here we aimed to investigate the prognostic and diagnostic impact of NLR, PLR, and Fibrinogen in patients with thymic epithelial tumors (TETs). Results: Pretreatment Fibrinogen serum concentrations, NLRs and PLRs were highest in patients with TCs and advanced tumor stages...

BACKGROUND: Vaccine hesitancy has been recognized as a major global health threat. Having access to any type of information in social media has been suggested as a potential influence on the growth of anti-vaccination groups. Recent studies w.r.t. other topics than vaccination show that access to a wide amount of content through the Internet without intermediaries resolved into major segregation of the users in polarized groups. Users select information adhering to theirs system of beliefs and tend to ignore dissenting information...

BACKGROUND: The age-specific association between blood pressure and vascular disease has been studied mostly in high-income countries, and before the widespread use of brain imaging for diagnosis of the main stroke types (ischaemic stroke and intracerebral haemorrhage). We aimed to investigate this relationship among adults in China. METHODS: 512 891 adults (59% women) aged 30-79 years were recruited into a prospective study from ten areas of China between June 25, 2004, and July 15, 2008...

BACKGROUND: China has high stroke rates despite the population being relatively lean. Uncertainty persists about the relevance of adiposity to risk of stroke types. We aimed to assess the associations of adiposity with incidence of stroke types and effect mediation by blood pressure in Chinese men and women. METHODS: The China Kadoorie Biobank enrolled 512 891 adults aged 30-79 years from ten areas (five urban and five rural) during 2004-08. During a median 9 years (IQR 8-10) of follow-up, 32 448 strokes (about 90% confirmed by neuroimaging) were recorded among 489 301 participants without previous cardiovascular disease...

Children with disabilities utilize more health-care services and incur higher costs than other children do. Medicaid Buy-In programs for children with disabilities have the potential to increase access to benefits while reducing out-of-pocket costs for families whose income exceeds Medicaid eligibility. This study sought to understand how parents and caregivers of Massachusetts children with disabilities perceive access to care under CommonHealth, Massachusetts's Medicaid Buy-In program. Parents and caregivers ( n = 615) whose children were enrolled in CommonHealth participated in a survey assessing the impact of the program...

BACKGROUND: Aortic abdominal aneurysms are a potentially deathly disease, needing surgical or endovascular treatment. To evaluate potentially new diagnostic tools and treatments a large animal model, which not only resembles the morphological characteristics but also the pathophysiological background, would be useful. MATERIALS AND METHODS: Rodent animal aneurysm models were extrapolated to sheep. Four groups were created: intraluminal infusion with an elastase-collagenase solution (n=4), infusion with elastase-collagenase solution combined with proximal stenosis (n=7), aortic xenograft (n=3), and elastase-collagenase treated xenograft (n=4)...

BACKGROUND: Mutations in the Recombinase Activating Gene 1 and 2 (RAG1, RAG2) are associated with a broad range of clinical and immunological phenotypes in humans. OBJECTIVE: Using a flow cytometry-based assay, we aimed to measure the recombinase activity of naturally occurring RAG2 mutant proteins, and to correlate results with the severity of the clinical and immunological phenotype. METHODS: Abelson virus-transformed Rag2-/- pro-B cells engineered to contain an inverted GFP cassette flanked by recombination signal sequences (RSS) were transduced with retroviruses encoding either wild-type or 41 naturally occurring RAG2 variants...

The authors present a case of a pregnant woman with uveal melanoma treated with plaque brachytherapy. Her calculated fetal radiation dose was significantly below accepted levels. The use of the authors' novel, custom-made lead chin shield further diminished irradiation of the fetus. This patient had uncomplicated treatment course, delivered a healthy child full term, achieved local tumor control, and maintained 20/25 vision at 1-year follow-up.

INTRODUCTION: The isometric force attained after active stretch is greater than that attained in a purely isometric contraction. This property is referred to as residual force enhancement (RFE). Although RFE is thought to contribute to the enhanced force and power in stretch-shortening cycles (SSCs), it is unclear whether shortening that occurs after active stretch eliminates the RFE induced by active stretch. Therefore, we evaluated the influence of shortening on RFE. METHODS: Skinned rabbit soleus fibers (N = 43) were used for all tests...

Although many nursing programs provide diversity training to enhance the understanding of cultural influences on health care, little is known about outcomes. This is due in part to a lack of consensus regarding definitions and measures. The purpose of this study was to examine a set of self-perceptions defined as personal growth, attributed by graduate nursing students (N = 41) to an eight-week diversity course. Participants reported modest levels of personal growth. Educators can adapt the instrument and method of this study to measure student attributions of growth to any aspect of nursing education...

Till Wüstemann, Uwe Haberkorn, John Babich, Walter Mier
The high incidence rates of prostate cancer (PCa) raise demand for improved therapeutic strategies. Prostate tumors specifically express the prostate-specific membrane antigen (PSMA), a membrane-bound protease. As PSMA is highly overexpressed on malignant prostate tumor cells and as its expression rate correlates with the aggressiveness of the disease, this tumor-associated biomarker provides the possibility to develop new strategies for diagnostics and therapy of PCa. Major advances have been made in PSMA targeting, ranging from immunotherapeutic approaches to therapeutic small molecules...
