OBJECTIVES: To investigate the opinions of lung cancer clinicians concerning shared decision making (SDM) in early-stage non-small-cell lung cancer patients. METHODS: A survey was conducted among Dutch cardiothoracic surgeons and lung surgeons, pulmonologists and radiation oncologists. The opinions of clinicians on the involvement of patients in treatment decision making was assessed using a 1-5 Likert-type scale. Through open questions, we queried barriers to and drivers of SDM in clinical practice...

In dual-tasks, characteristics of Task 2 responses can already affect performance in the preceding Task 1. This is called the backward crosstalk effect (BCE). To account for the BCE, it has been suggested that the appearance of the Task 2 stimulus automatically projects activation onto the corresponding response through (transient or direct) stimulus-response (S-R) links. One way to investigate this claim is to compare the size of the BCE for tasks where S-R links are differently strong. To this end, we here compared BCEs for forced- vs...

Paracetamol (acetaminophen) is a widely used non-prescription drug with analgesic and antipyretic properties. Among pregnant women and young children, paracetamol is one of the most frequently used drugs and is considered the first-choice treatment for pain and/or fever. Recent findings in both human and animal studies have shown associations between paracetamol intake during brain development and adverse behavioral outcomes later in life. The present study was undertaken to investigate if the induction of these effects depend on when the exposure occurs during a critical period of brain development and if male and female mice are equally affected...

Replacing hydroxyl anions OH¯ by fluorine anions F¯ in borates can cause the blue shift of the UV cutoff edge and also exhibits apparent differences in nonlinear optical (NLO) properties. To clarify the intrinsic difference between OH¯ anions and F¯ anions, several typical borates with different types of cations (p-cations with lone-pair electrons, trivalent rare-earth, and alkaline earth metals) have been studied. The theoretical studies reveal that the blue shift in the band gap of borates with fluorine as compared to those with hydroxyl can be assumed to be the result of weaker interaction of the cation-fluoride (La/Bi/B-F) bonds compared to that of the cation-oxygen and hydroxyl bonds...

In this work, we report a newly observed isotope shift between (162)Dy and (164)Dy isotopes for the 0 → 16 717.79 cm(-1) (598.003 nm) optical transition. We compared the newly observed results against two other lines (597.452 nm and 598.859 nm), which we measured in this work, and were already reported in the literature. The newly observed 162-164 Dy isotope shift, shows at least a 20% larger isotope shift than the isotope shifts for the other two lines investigated. The larger 162-164 isotope shift observed for the 598...

INTRODUCTION: The most common primary tumors of brain are gliomas and tumor grading is essential for designing proper treatment strategies. The gold standard choice to determine grade of glial tumor is biopsy which is an invasive method. The purpose of this study was to investigate the role of fiber density index (FDi) by means of diffusion tensor imaging (DTI) (as a noninvasive method) in glial tumor grading. METHODS: A group of 20 patients with histologically confirmed diagnosis of gliomas were evaluated in this study...

PURPOSE OF REVIEW: Cost-effective care pathways are integral to delivering sustainable healthcare programmes. Due to the overestimation of coronary artery disease using traditional risk tables, non-invasive testing has been utilised to improve risk stratification and initiate appropriate management to reduce the dependence on invasive investigations. In line with recent technological improvements, cardiac CT is a modality that offers a detailed anatomical assessment of coronary artery disease comparable to invasive coronary angiography...

Establishing a cure for HIV is hindered by the persistence of latently infected cells which constitute the viral reservoir. Real-time qPCR, used for quantification of this reservoir by measuring HIV DNA, requires external calibration; a common choice of calibrator is the 8E5 cell line, which is assumed to be stable and to contain one HIV provirus per cell. In contrast, digital PCR requires no external calibration and potentially provides 'absolute' quantification. We compared the performance of qPCR and dPCR in quantifying HIV DNA in 18 patient samples...

BACKGROUND: Pancreatic cancer is a highly lethal disease with a poor prognosis while metformin has been associated with a decreased risk of pancreatic cancer. Although the benefit of metformin was observed for pancreatic cancer prevention, it is not clear whether it can also affect the survival of pancreatic cancer patients with type 2 diabetes mellitus. A systematic review and meta-analysis was conducted to assess the effect of metformin on the survival of pancreatic cancer patients with type 2 diabetes mellitus...

As China becomes the world's largest energy consumer and CO2 emitter, there has been a rapidly emerging literature on estimating China's abatement cost for CO2 using a distance function approach. However, the existing studies have mostly focused on the cost estimates at macro levels (provinces or industries) with few examining firm-level abatement costs. No work has attempted to estimate the abatement cost of CO2 emissions in the iron and steel industry. Although some have argued that the directional distance function (DDF) is more appropriate in the presence of bad output under regulation, the choice of directions is largely arbitrary...

BACKGROUND: In the past decade, the minimally invasive repair of pectus excavatum (MIRPE) has become the treatment of choice for severe pectus excavatum (PE), proving acceptable to excellent cosmetic results. Recently, autologous fat grafting (FG) has been identified in aesthetic and reconstructive surgery to ideally handle volume and contour defects. We report our experience about FG in the treatment of residual minor defects after MIRPE and a proposal for a new indication of this largely adopted technique...

Purpose: Biliary tract cancer (BTC)is an aggressive disease with a poor prognosis. Most patients are diagnosed at an advanced stage for which curative surgery is not possible and gemcitabine-platinum chemotherapy is the treatment of choice for advanced cases. Several studies had focused on biomarkers to predict response from platinum drugs in lung cancer, but information is limited for BTC. In this study, two single nucleotide polymorphisms (SNPs) in the copper transporter (CTR1) and excision repair cross-complementary group 1 (ERCC1) genes were investigated as predictive biomarkers of objective response to gemcitabine-platinum...

INTRODUCTION: The number of distractors needed for high quality multiple choice questions (MCQs) will be determined by many factors. These include firstly whether English language is their mother tongue or a foreign language; secondly whether the instructors who construct the questions are experts or not; thirdly the time spent on constructing the options is also an important factor. It has been observed by Tarrant et al that more time is often spent on constructing questions than on tailoring sound, reliable, and valid distractors...

Following the rapid expansion of the proteomics field, the investigation of post translational modifications (PTM) has become extremely popular changing our perspective of how proteins constantly fine tune cellular functions. Reversible protein phosphorylation plays a pivotal role in virtually all biological processes in the cell and it is one the most characterized PTM up to date. During the last decade, the development of phosphoprotein/phosphopeptide enrichment strategies and mass spectrometry (MS) technology has revolutionized the field of phosphoproteomics discovering thousands of new site-specific phosphorylations and unveiling unprecedented evidence about their modulation under distinct cellular conditions...

Choices about when to transition between two modes of behaviour are determined by the fit between action capabilities and environmental properties. However, such transitions typically occur not at the absolute limits of action capabilities but rather based on the relative stability of each mode. People transition from an arm-only to an arm-plus-torso-reach, not when object distance exceeds arm length but when the stability of reaching with the arm-plus-torso exceeds that of reaching with the arm only. To the extent that perception is supported by detection of invariant stimulation patterns, such a transition ought to reflect both the fit between action capabilities and environmental properties and the relative stability of modes regardless of species...

Damage of retinal ganglion cells (RGCs) is the major consequence of glaucoma and regeneration of RGCs is extremely difficult once the damage has occurred. Retinal stem cells (RSCs) are considered an ideal choice for RGC regeneration. Pigmented cells from the ciliary margin (PCMs) have great retinal differentiation potential and may be an ideal RSC candidate. However, the ciliary margin is too small, so the number of cells that can be obtained is limited. Bone marrow‑derived mesenchymal stem cells (BMMSCs) are another type of stem cell that have been previously investigated for RGC regeneration...

This paper examines the decline in non-numeric responses to questions about fertility preferences among women in the developing world. These types of response-such as 'don't know' or 'it's up to God'-have often been interpreted through the lens of fertility transition theory as an indication that reproduction has not yet entered women's 'calculus of conscious choice'. However, this has yet to be investigated cross-nationally and over time. Using 19 years of data from 32 countries, we find that non-numeric fertility preferences decline most substantially in the early stages of a country's fertility transition...
