The consequences of the 2013-16 Ebola Zaire virus disease epidemic in West Africa were grave. The economies, healthcare systems and communities of Guinea, Sierra Leone and Liberia were devastated by over 18 months of active Ebola virus transmission, followed by sporadic resurgences potentially related to sexual transmission by survivors with viral persistence in body fluids following recovery. The need to develop and implement strategies to prevent and mitigate future outbreaks is now beyond dispute. The potential for unpredictable outbreaks of indeterminate duration, and control challenges posed by the possibility of sporadic re-emergence, mean that implementation of an effective vaccination programme for outbreak containment necessitates a vaccine providing durable immunity...

Arthroereisis is a rare and disputed procedure, where an implant screw is inserted into the sinus tarsi to treat flatfoot deformity. Weight-bearing radiographs are the most essential examinations to assess the correct localization and related measurements. Hardware loosening is the most common complication seen as localized lucency and as dislocation of the implant. Computed tomography yields superior resolution with reconstruction capabilities. On magnetic resonance imaging, the implant appears as a dark signal focus on T1 and T2-weighted images with a hyperintense T2-signal rim...

PREMISE OF THE STUDY: Revealing the relative roles of gradual and abrupt transformations of morphological characters is an important topic of evolutionary biology. Gynoecia apparently consisting of one carpel have evolved from pluricarpellate syncarpous gynoecia in several angiosperm clades. The process of reduction can involve intermediate stages, with one fertile and one or more sterile carpels (pseudomonomery). The possible origin of monomery directly via an abrupt change of gynoecium merism has been a matter of dispute...

REVIEW
Byron B Lamont, Tianhua He
Fire as a major evolutionary force has been disputed because it is considered to lack supporting evidence. If a trait has evolved in response to selection by fire then the environment of the plant must have been fire-prone before the appearance of that trait. Using outcomes of trait assignments applied to molecular phylogenies for fire-stimulated flowering, seed-release, and germination, in this Opinion article we show that fire-proneness precedes, or rarely coincides with, the evolution of these fire-adapted traits...

Catheter ablation for rhythm control in atrial fibrillation has been recognized as an established treatment. Patients with atrial fibrillation suffer from an increased risk from thromboembolic events. Long-term stroke risk and mortality has been shown to be reduced after catheter ablation, still the procedure per se is associated with an additive peri-procedural thromboembolic risk. Maintenance of the thrombotic - bleeding equilibrium in such patients during interventional procedures is compelling. Lack of data from randomized studies along with the recent introduction of novel oral anticoagulants in clinical practice has resulted in a wide variance of antithrombotic treatment approaches...

The interferon-inducible protein Z-DNA binding protein 1 (ZBP1, also known as DNA-dependent activator of IFN-regulatory factors (DAI) and DLM-1) was identified as a dsDNA sensor, which instigates innate immune responses. However, this classification has been disputed and whether ZBP1 functions as a pathogen sensor during an infection has remained unknown. Herein, we demonstrated ZBP1-mediated sensing of the influenza A virus (IAV) proteins NP and PB1, triggering cell death and inflammatory responses via the RIPK1-RIPK3-Caspase-8 axis...

OBJECTIVE: The aim of this study was to use subjective and objective methods to investigate the effects of total or nearly total nasal obstruction due to nasal polyposis on nasal resonance and voice perception. PATIENTS AND METHODS: A total of 63 nasal polyposis patients (53 men and 10 women), aged between 19 and 72 years (mean age 37.01 ± 13.70), were included in the study. The severity of the nasal obstruction was assessed using a visual analog scale. Nasal resonance and voice perception were evaluated subjectively by the voice handicap index (VHI)-10 questionnaire and objectively by computerized analysis (nasometry) before and after treatment of patients with nasal polyposis...

The epidural space is frequently used for placement of the epidural needle, catheter, and various pharmacological agents. The presence of structures in the epidural space such as epidural fat, venous plexus, or ligaments that may lead to uneven distribution of agents within the epidural space have been described.(1-3) Whether these structures are anatomical (such as connective tissue) or functional (due to distortions of actual anatomy secondary to injection of agents epidurally) has been disputed.(2-5) We describe our management of a patient who presented with bilateral radicular symptoms and severe low back pain...

The introduction of a certification / diploma program in Minimal Invasive Surgery (MIS) is expected to improve surgical performance, patient's safety and outcome. The Gynaecological Endoscopic Surgical Education and Assessment programme (GESEA) and the ESHRE Certification for Reproductive Endoscopic Surgery (ECRES) provides a structured learning path, recognising different pillars of competence. In order to achieve a high level of competence a two steps validation is necessary: (a) the individual should be certified of having the appropriate theoretical knowledge and (b) the endoscopic psychomotor skills before entering in the diploma programme reflecting the surgical competence...

The issue of medical futility requires a well-defined process in which both sides of the dispute can be heard and a resolution reached in a fair and ethical manner. Procedural approaches to medical futility cases provide all parties involved with a process-driven framework for resolving these disputes. Medical paternalism or the belief in the absolute rightness of the medical model will not serve to resolve these disputes. Although medical futility is first determined by medicine, in order for the determination to meet legal criteria, it must be subject to review...

RNA binding motif, single stranded interacting protein 3 (RBMS3) has been reported as a tumor suppressor gene (TSG) in some squamous carcinoma. However, its expression levels and clinical significance in gastric cancer (GC) remains unclear. Secreted frizzled-related protein 1 (SFRP1) plays a role of tumor suppressor in many cancers by inhibiting Wnt/β-catenin pathway. Nevertheless, its expression levels and clinical significance in GC are in dispute. In this study, quantitative real-time PCR and Western Blot were used to measure the mRNA and protein level of RBMS3 and SFRP1 in 23 fresh GC and corresponding normal tissues...

BACKGROUND: The sawtooth sign in spirometry is associated with redundant upper airway tissue and snoring, but its predictive value for identifying obstructive sleep apnea (OSA) is disputed. We retrospectively assessed the predictive value of the spirometric sawtooth sign in terms of the odds ratio (OR) of association with a diagnosis of OSA compared to those without the sign. METHODS: Consecutive spirometry reports showing a sawtooth sign were identified from our laboratory...

The role of androgen and androgen receptor (AR) in breast carcinogenesis has long been a disputed issue. This report provides a mechanistic insight into how androgen and AR contributes to invasion and metastasis of breast cancer. We find that dihydrotestosterone (DHT) is able to induce the epithelial-to-mesenchymal transition in breast cancer cells in an AR-dependent/estrogen receptor-independent manner. This process is dependent on the demethylation activity of lysine-specific demethylase 1A (LSD1) by epigenetically regulating the target genes E-cadherin and vimentin...

The association between pre-hematopoietic stem cell transplantation (HSCT) vancomycin-resistant Enterococcus (VRE) colonization, HSCT associated VRE bacteremia, and HSCT mortality is disputed. We studied 161 consecutive patients with acute leukemia who underwent HSCT at our hospital between 2006 and 2014, of whom 109 also received leukemia induction/consolidation on our unit. All inpatients had weekly VRE stool surveillance. Pre-HSCT colonization was not associated with increases in HSCT mortality but did identify a subgroup of HSCT recipients with a higher risk for VRE bacteremia and possibly bacteremia from other organisms...

REVIEW

Homonymous hemianopia from stroke causes visual disability. Although some patients experience spontaneous improvement, others have limited to no change and may be left with a severe disability. Current rehabilitation strategies are compensatory and cannot restore function. Animal studies suggest that central nervous system plasticity could allow for redirection of lost visual function into undamaged areas of cortex. A commercial therapy system was developed, from which claims of visual field expansion were disputed by independent researchers...

Pr(3+)/Yb(3+) doped materials have been widely reported as quantum-cutting materials in recent times. However, the question of the energy transfer mechanism in the Pr(3+)/Yb(3+) pair in light of the quantum-cutting phenomenon still remains unanswered. In view of that, we explored a series of Pr(3+)/Yb(3+) co-doped low phonon fluorotellurite glass systems to estimate the probability of different energy transfer mechanisms. Indeed, a novel and simple way to predict the probability of the proper energy transfer mechanism in the Pr(3+)/Yb(3+) pair is possible by considering the donor Pr(3+) ion emission intensities and the relative ratio dependence in the presence of acceptor Yb(3+) ions...

After UV excitation, gas phase thymine returns to a ground state in 5 to 7 ps, showing multiple time constants. There is no consensus on the assignment of these processes, with a dispute between models claiming that thymine is trapped either in the first (S₁) or in the second (S₂) excited states. In the present study, a nonadiabatic dynamics simulation of thymine is performed on the basis of ADC(2) surfaces, to understand the role of dynamic electron correlation on the deactivation pathways. The results show that trapping in S₂ is strongly reduced in comparison to previous simulations considering only non-dynamic electron correlation on CASSCF surfaces...

There is both individual and collective widespread concern in society about the impact of human activity and the effects of our decisions on the physical and social environment. This concern is included within the idea of sustainability. The meaning of the concept is still ambiguous and its practical effectiveness disputed. Like many other authors, this article uses as a starting point the definition proposed by the World Commission on Environment and Development (Our common future, Oxford University Press, Oxford, 1987), considering it to be a proposal for changing the assessment of the effects of decisions, from at least two perspectives: (1) what effects we should consider and (2) how we should assess them...
