BACKGROUND: Bill C-14 allows for medical assistance in dying (MAID) for patients who have intolerable physical or psychological suffering that occurs in the context of a reasonably foreseeable death. In Canada, psychiatrist support for MAID on the basis of mental illness and beliefs influencing level of support are unknown. The objectives of this research were to 1) determine if psychiatrists are supportive of MAID under certain conditions and on the basis of mental illness and 2) determine what factors are related to psychiatrist support for MAID on the basis of mental illness...

Although ibrutinib is highly effective in Waldenstrom macroglobulinemia (WM), no complete remissions in WM patients treated with ibrutinib have been reported to date. Moreover, ibrutinib-resistant disease is being steadily reported and is associated with dismal clinical outcome (overall survival of 2.9-3.1 months). To understand mechanisms of ibrutinib resistance in WM, we established ibrutinib-resistant in vitro models using validated WM cell lines. Characterization of these models revealed the absence of BTK(C481S) and CXCR4(WHIM-like) mutations...

We review current findings associating socioeconomic status (SES), development of neurocognitive functions, and neurobiological pathways. A sizeable interdisciplinary literature was organized through a bifurcated developmental trajectory (BiDeT) framework, an account of the external and internal variables associated with low SES that may lead to difficulties with attention and learning, along with buffers that may protect against negative outcomes. A consistent neurocognitive finding is that low-SES children attend to information nonselectively, and engage in late filtering out of task-irrelevant information...

Adenocarcinoma (ADC) and squamous cell carcinoma (SqCC) are the two predominant subtypes of non-small cell lung cancer (NSCLC) and are distinct in their histological, molecular and clinical presentation. However, metabolic signatures specific to individual NSCLC subtypes remain unknown. Here, we perform an integrative analysis of human NSCLC tumour samples, patient-derived xenografts, murine model of NSCLC, NSCLC cell lines and The Cancer Genome Atlas (TCGA) and reveal a markedly elevated expression of the GLUT1 glucose transporter in lung SqCC, which augments glucose uptake and glycolytic flux...

Memory is lost by the increased influx of extracellular Zn(2+) into neurons. It is possible that intracellular Zn(2+) dynamics is modified even at non-zincergic medial perforant pathway-dentate granule cell synapses along with aging and that vulnerability to the modification is linked to age-related cognitive decline. To examine these possibilities, vulnerability of long-term potentiation (LTP) maintenance, which underlies memory retention, to modification of synaptic Zn(2+) dynamics was compared between young and aged rats...

Biodiversity conservation is one of the grand challenges facing society. Many people interested in biodiversity conservation have a background in wildlife biology. However, the diverse social, cultural, political, and historical factors that influence the lives of people and wildlife can be investigated fully only by incorporating social science methods, ideally within an interdisciplinary framework. Cultural hierarchies of knowledge and the hegemony of the natural sciences create a barrier to interdisciplinary understandings...

In Italy healthcare is provided for all Italian citizens and residents and it is delivered mainly by public providers, with some private or private-public entities. Italy's public healthcare system - the Servizio Sanitario Nazionale (SSN) - is organised by the Ministry of Health and administered on a devolved regional basis. It is financed by general taxation that provides universal coverage, largely free of charge at the point of service. The central government establishes the basic national health benefits package, which must be uniformly provided throughout the country, through services guaranteed under the NHS provision called LEA - (Livelli Essenziali di Assistenza [Essential Level of Assistance]) and allocates national funds to the regions...

In sensory hair cells of auditory and vestibular organs, the ribbon synapse is required for the precise encoding of a wide range of complex stimuli. Hair cells have a unique presynaptic structure-the synaptic ribbon-that organizes both synaptic vesicles and calcium channels at the active zone. Previous work has shown that hair-cell ribbon size is correlated with differences in postsynaptic activity. However, additional variability in postsynapse size presents a challenge to determining the specific role of ribbon size in sensory encoding...

Dystonia is a movement disorder characterized by sustained or intermittent muscle contractions. Its pathophysiological mechanisms are still poorly understood. Dominant mutations of the GNAL gene are a cause of isolated dystonia (DYT25) in patients. Some mutations result in a complete loss of function of the encoded protein, Gαolf, an adenylyl-cyclase-stimulatory G protein highly enriched in striatal projection neurons, in which it mediates the actions of dopamine and adenosine. We used male and female heterozygous Gnal knockout mice (Gnal+/-) to study how GNAL haplodeficiency is implicated in dystonia...

OBJECTIVE: Adverse life events may contribute to the emergence of suicidality. We aimed to test the relationship between the impact of the Greek recession and suicidal risk in people with long-term conditions (LTCs) and to determine whether this relationship is moderated by the presence of a mental disorder. METHODS: Suicidal risk (RASS) and crisis parameters were assessed in a cross-sectional survey including 376 patients with LTCs (type-II diabetes mellitus, rheumatological disorders and chronic obstructive pulmonary disease) attending the Emergency Department or specialty clinics...

Amid increased attention to quality of obstetric care and respectful maternity care globally, insufficient focus has been given to quality of care and respectful care for newborns in the postnatal period. Especially in low and middle income countries, where low utilisation of obstetric and neonatal services is of concern, it is plausible that poor quality of care or mistreatment of newborns or stillborn infants will influence future care seeking, both for the health care needs of the growing infant and for subsequent pregnancies...

BACKGROUND: The police and others in occupations where they come into close contact with people experiencing/with mental ill health, often have to manage difficult and complex situations. Training is needed to equip them to recognise and assist when someone has a mental health issue or learning/intellectual disability. We undertook a systematic review of the effectiveness of training programmes aimed at increasing knowledge, changing behaviour and/or attitudes of the trainees with regard to mental ill health, mental vulnerability, and learning disabilities...

BACKGROUND: Lower respiratory illnesses (LRIs) and asthma are common diseases in children <5 years of age. Few studies have investigated the relationships between multiple, home-based social and environmental risk factors and asthma and LRIs in children. Of those that have, none have focused exclusively on children <5 years of age, who are more physiologically vulnerable and spend more time at home compared to older children. Further, no studies have done so at the community level...

In order to identify victims of child neglect, social service workers rely heavily on referrals from concerned friends, neighbors, and others in the community. Little is known, however, about how lay individuals perceive child neglect and what factors influence their decision to make a referral. This study explored the effects of child, parent, and participant gender on laypersons' evaluations of child neglect. Participants read a case of neglect of a child by a custodial and absent parent and then rated the parents' culpability and intentionality and decided whether the parents' behavior met the legal definition of neglect...

Depression currently affects 350 million people worldwide and 19 million Americans each year. Women are 2.5 times more likely to experience major depression than men, with some women appearing to be at a heightened risk during the menopausal transition. Estrogen signaling has been implicated in the pathophysiology of mood disorders including depression; however, the underlying mechanisms are poorly understood. In this study, the role of estrogen receptor (ER) subtypes, ERα and ERβ, in the regulation of brain-derived neurotrophic factor (BDNF) and serotonin (5-HT) signaling was investigated; two pathways that have been hypothesized to be interrelated in the etiology of depression...

Intolerance of uncertainty is an empirically supported transdiagnostic construct that may have relevance in understanding eating disorders. We conducted a meta-analysis and systematic review of intolerance of uncertainty in eating disorders using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We calculated random-effects standardised mean differences (SMD) for studies utilising the Intolerance of Uncertainty Scale (IUS) and summarised additional studies descriptively...

Conditions experienced early in life can shape brain development and later cognition. Altricial songbirds are particularly vulnerable to early environmental perturbations. Research on "Developmental Stress" in songbirds has addressed how early-life conditions may impair song learning and has been extended to consider other components of adult phenotype. Early-life challenges ranging from ectoparasites to competition with siblings have been shown to compromise song learning and other measures of cognition, as well as behavioral strategy...

BACKGROUND: Older people are sometimes challenged in maintaining a healthy diet but, because of age and disadvantage, are also more vulnerable to the adverse health consequences of poor nutrition. It has been claimed that older adults have low levels of health literacy regarding food and struggle to discern which foods are healthy from the vast range available in developed counties (Br Herne 1995;97:12). However, nutrition and eating behaviour are modifiable risk factors for health in old age (Appl Physiol Nutr Keller 2007;32:991) and health benefits can accrue from promoting healthy eating later in life...

Species endemic to the tropical regions are expected to be vulnerable to future climate change due in part to their relatively narrow climatic niches. In addition, these species are more likely to have responded strongly to past climatic change, and this can be explored through phylogeographic analyses. To test the hypothesis that tropical specialists are more sensitive to climate change than climate generalists, we generated and analyze sequence data from mtDNA and ~2500 exons to compare scales of historical persistence and population fluctuation in two sister species of Australian rainbow skinks: the tropical specialist Carlia johnstonei and the climate generalist C...
