Direct-to-consumer (DTC) genetic tests (GT) have provoked criticism over their potential adverse impact on public health. The European Parliament called for a ban on DTC advertising of GT during the debate for the adoption of a European Regulation on in vitro diagnostic medical devices. This proposal, however, was not ultimately retained in the final text. Instead, the regulation includes an article prohibiting misleading claims for this kind of advertising. These two different approaches raise questions about the optimal degree of regulation...

OBJECTIVES: This study sought to evaluate the prognostic value of mean pressure gradient (MPG) increase and peak systolic pulmonary artery pressure (SPAP) measured during exercise stress echocardiography in asymptomatic patients with aortic stenosis (AS). BACKGROUND: Exercise testing is recommended in asymptomatic AS patients, but the additional value of exercise-stress echocardiography, especially the prognostic value of MPG increase and peak SPAP, is still debated...

There is a consensus that visual working memory (WM) resources are sharply limited, but debate persists regarding the simple question of whether there is a limit to the total number of items that can be stored concurrently. Zhang and Luck (2008) advanced this debate with an analytic procedure that provided strong evidence for random guessing responses, but their findings can also be described by models that deny guessing while asserting a high prevalence of low precision memories. Here, we used a whole report memory procedure in which subjects reported all items in each trial and indicated whether they were guessing with each response...

There is an ongoing public debate on the diagnosis of attention deficit hyperactivity disorder (ADHD) in which critics have claimed that the disorder is over-diagnosed, while the potential under-diagnosis of children with ADHD has received little attention. In this study we estimate the number of children with parent-reported ADHD behaviour at age 7 and absence of recorded ADHD diagnosis through adolescence, and investigate whether socio-demographic characteristics of this group differed from the children diagnosed with ADHD during follow-up...

Most treatment guidelines, including those from the American Diabetes Association/European Association for the Study of Diabetes and the International Diabetes Federation, suggest metformin be used as the first-line therapy after diet and exercise. This recommendation is based on the considerable body of evidence that has accumulated over the last 30 years, but it is also supported on clinical grounds based on metformin's affordability and tolerability. As such, metformin is the most commonly used oral antihyperglycemic agent in the U...

Denosumab (Dmab) is a humanized monoclonal antibody that blocks RANKL (receptor activator for nuclear factor κB ligand), thereby exerting a potent bone antiresorptive action. Dmab treatment leads to a dramatic and sustained increase in bone mass through mechanisms that are currently under debate. It is also a matter of controversy whether this potent action of Dmab could lead to intrabone dystrophic mineralization. Recent research has uncovered a possible anabolic role of Dmab involving RANKL-dependent reverse signaling in osteoblasts, and that bone marrow adipocytes can modulate osteoclastogenesis through the production of RANKL...

This paper examines inter-bureaucracy tension, negotiation, and resolution in the case of the oversight of beverage room sanitation in Ontario in the 1930s and 1940s. Both the Liquor Control Board of Ontario (LCBO) and various public health authorities claimed authority over the health status of public drinking spaces. But the LCBO had legislative priority. The ensuing debates regarding health and cleanliness linked issues of beverage room glass sanitation to a biopolitical approach to public drinking. Developing a more scientifically sophisticated approach to beverage glass cleaning required a balancing of administrative priorities...

Scenarios summarize evolutionary patterns and processes by interpreting organismal traits and their natural history correlates in a phylogenetic context. They are constructed by (1) describing phenotypes (including physiology and behavior), ideally with attention to formative roles of development, experience, and culture; (2) inferring homologies, homoplasies, ancestral character states, and their transformations with phylogenetic analyses; and (3) integrating those components with ecological and other ancillary data...

AIM: The association of sodium (Na) and potassium (K) intake with blood pressure (BP) is an ongoing debate, especially in central Iran. We aimed to examine the mean Na and K intake, major sources of Na and the relationship between BP and dietary and urinary Na and K. METHODS: This cross-sectional study was performed in central Iran in 2013-2014. A total of 796 non-hypertensive adults aged >18 years were randomly recruited. The semi-quantitative food frequency questionnaire was used to assess dietary Na and K intake...

Generating plants with increased yields while maintaining low production and maintenance costs is highly important since plants are the major food source for humans and animals, as well as important producers of chemicals, pharmaceuticals, and fuels. Gene editing approaches, particularly the CRISPR-Cas system, are the preferred methods for improving crops, enabling quick, robust, and accurate gene manipulation. Nevertheless, new breeds of genetically-modified crops have initiated substantial debates concerning their biosafety, commercial use, and regulation...

Unraveling the mechanistic details of copper-catalyzed arylation of nucleophiles (Ullmann-type couplings) is a very challenging task. It is a matter of intense debate whether it is a radical-based process or an organometallic redox-based process. The ancillary ligand choice in Ullmann-type couplings plays a key role in such transformations and can strongly influence the catalytic efficiency as well as the mechanism. Here, we show how a predesigned tridentate pincer-like catalyst undergoes a deactivation pathway through a Cu(I)/Cu(III) prototypical mechanism as demonstrated by helium-tagging infrared photodissociation (IRPD) spectroscopy and DFT studies, lending a strong support to the existence of an aryl-Cu(III) species in the Ullmann couplings using this tridentate ligand...

Food contact materials (FCM) contain chemicals which can migrate into food and result in human exposure. Although it is mandatory to ensure that migration does not endanger human health, there is still no consensus on how to pragmatically assess the safety of FCM since traditional approaches would require extensive toxicological and analytical testing which are expensive and time consuming. Recently, the combination of bioassays, analytical chemistry and risk assessment has been promoted as a new paradigm to identify toxicologically relevant molecules and address safety issues...

PURPOSE: Prostate specific antigen (PSA) has been widely used as the unique serum biomarker for the diagnosis and/ or pre-diagnosis of prostate cancer (PCa). However, the diagnostic value of PSA is a subject of ongoing debate owing to its lack of specificity, especially when the PSA level is moderately increased (e.g., 4-10 ng/ml). Thus, we suggest the need for identification of a new biomarker to discriminate PCa cases from benign prostatic hyperplasia (BPH) and normal controls (N). METHODS: Urine or tissue samples of PCa patients, BPH patients, and normal controls were systematically collected...

Given that more than 30% of healthcare costs are wasted on inappropriate care, suboptimal care is increasingly connected to the quality of medical decisions. It has been argued that personal decisions are the leading cause of death, and 80% of healthcare expenditures result from physicians' decisions. Therefore, improving healthcare necessitates improving medical decisions, ie, making decisions (more) rational. Drawing on writings from The Great Rationality Debate from the fields of philosophy, economics, and psychology, we identify core ingredients of rationality commonly encountered across various theoretical models...

Although the roles of introns have been much debated in eukaryotic organisms, none of them have been functionally characterized in Fusarium graminearum. In this study, we characterized the roles of introns in regulation of fungicide-sensitivity of F. graminearum. β2 tub, cyp51A and myosin-5 are important target genes of benzimidazoles, triazoles and cyanoacrylates, respectively. To explore the sensitivity regulation functions of introns in target genes, several detailed deletion studies were completed on the intronic regions of β2 tub, cyp51A, myosin-5...

M Nasiri Sarvi, Y Luo
Osteoporotic hip fracture, mostly induced in falls among the elderly, is a major health burden over the world. The impact force applied to the hip is an important factor in determining the risk of hip fracture. However, biomechanical researches have yielded conflicting conclusions about whether the fall-induced impact force can be accurately predicted by the available models. It also has been debated whether or not the effect of impact force has been considered appropriately in hip fracture risk assessment tools...

"Everyone's right to life shall be protected by law", states the article 2 of the European Convention of Human Rights (1950). This article guarantees the protection of life of all persons. The human embryo, however, does not seem to be under the protection of this article, or, at least not always. The human embryo does not have a nature clearly defined and it is not considered always as person. The law protects only two categories by its ordinary regulations: things and persons. Our main objective is to find out if the human embryo is or not protected, according to the legal framework in Romania...

BACKGROUND: A decade has passed since South Africa signed and ratified the Convention on the Rights of Persons with Disabilities, a human rights treaty that protects the rights and dignity of people with disabilities. However, not much have changed for students with disabilities. OBJECTIVES: The aim of this study was to explore lecturers' experiences with, and perspectives on, disability as well as with students with disabilities. It was hoped that this would contribute to the ongoing policy debates about diversity, inclusion and support for students with disabilities at universities...
