Staphylococcus aureus (S. aureus) is one of the most common etiological agents in hospital-acquired infections and food-borne illness. S. aureus toxins and virulence proteases often circulate in host blood vessels leading to life-threatening diseases. Standard identification approaches include bacterial culturing method, which takes several days. Other nucleic acid-based methods were expensive and required trained personnel. To surmount these limitations, a paper-based biosensor was developed. The sensing mechanism was based on the proteolytic activity of S...

Recovery-oriented practices that promote client-centered care, collaboration, and functional outcome have been recommended to improve treatment engagement, especially for individuals with serious mental illness (SMI). Psychological well-being (PWB) is related to recovery and refers to experiencing purpose and meaning in life through realizing one's potential. The recently completed Recovery After an Initial Schizophrenia Episode Early Treatment Program (RAISE ETP) study sought to improve quality of life, functional outcome, and well-being in individuals with first episode psychosis (FEP)...

Viral foodborne illness continues to be a health-concern globally, with numerous fruit and juice outbreaks of Hepatitis A virus (HAV) reported worldwide. Aichi virus (AiV) is an emerging pathogen with limited epidemiological data. Both, HAV and AiV are resistant to low pH and can survive under adverse environmental conditions leading to transmission ease. The objective of this study was to evaluate the survival of HAV and AiV in commercially-available cranberry-based juices (Cranberry juice cocktail, CJ and a 100% juice with cranberry, MJ) over 21 days at refrigeration (4 °C)...

: Spore germination of 17 Bacillus cereus food isolates and reference strains was evaluated using flow cytometry analysis in combination with fluorescent staining at a single spore level. This approach allowed for rapid collection of germination data in more than 20 conditions including heat activation of spores, germination in complex media (BHI and TSB), and exposure to saturating concentrations of single amino acids and the combination of alanine and inosine. Whole genome sequence comparison revealed a total of eleven clusters of operons encoded germinant receptors (GRs); GerK, GerI and GerL were present in all strains, whereas GerR, GerS, GerG, GerQ, GerX, GerF, GerW and GerZ (sub)clusters showed a more diverse presence/absence in different strains...

Criminal prosecutions of individuals in the asbestos industry are reviewed, particularly the case of asbestos owner-executive Stephan Schmidheiny. Italian courts sentenced Schmidheiny to sixteen to eighteen years in jail for creating an environmental disaster causing three thousand deaths. The convictions were overturned on a technicality, and a murder case against Schmidheiny has started. His firm, Eternit, made asbestos-cement building products in many countries. Schmidheiny directed a cover-up that the Italian Court of Appeal blamed for delaying the ban of asbestos in Italy by ten years...

Strong familial aggregation of schizophrenia has been reported but there is uncertainty concerning the degree of genetic contribution to the phenotypic variance of the disease. This study aimed to examine the familial aggregation and heritability of schizophrenia, and the relative risks (RRs) of other psychiatric diseases, in relatives of people with schizophrenia using the Taiwan National Health Insurance Database. The study population included individuals with affected first-degree or second-degree relatives identified from all beneficiaries (n = 23 422 955) registered in 2013...

Schizophrenia is characterized by neuropsychological deficits across many cognitive domains. Cognitive phenotypes with high heritability and genetic overlap with schizophrenia liability can help elucidate the mechanisms leading from genes to psychopathology. We performed a meta-analysis of 170 published twin and family heritability studies of >800 000 nonpsychiatric and schizophrenia subjects to accurately estimate heritability across many neuropsychological tests and cognitive domains. The proportion of total variance of each phenotype due to additive genetic effects (A), shared environment (C), and unshared environment and error (E), was calculated by averaging A, C, and E estimates across studies and weighting by sample size...

BACKGROUND: Because the pattern of illnesses changes in an aging population and many people manage to live well with chronic diseases, a group of health care professionals recently proposed reformulating the static WHO definition of health towards a dynamic one based on the ability to physically, mentally and socially adapt and self-manage. This paper is the result of a collaborative action of the INTERDEM Social Health Taskforce to operationalize this new health concept for people with dementia, more specifically the social domain, and to formulate directions for research and practice to promote social health in dementia...

Schizophrenia and other major mental illnesses result from a complex interplay of genetic and environmental factors. We previously identified a mutation in NPAS3 that results in a valine to isoleucine (V304I) amino acid substitution segregating with schizophrenia in a small family. The amino acid change occurs in a potentially critical region for protein function. Furthermore, the same amino acid substitution in proteins related to familial Alzheimer's disease and transthyretin amyloidosis has been associated with protein aggregation...

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by a wide spectrum of deficits in social interaction, communication, and behavior. There is a significant genetic component to ASD, yet no single gene variant accounts for >1% of incidence. Posttranscriptional mechanisms such as microRNAs (miRNAs) regulate gene expression without altering the genetic code. They are abundant in the developing brain and are dysregulated in children with ASD. Patterns of miRNA expression are altered in the brain, blood, saliva, and olfactory precursor cells of ASD subjects...

BACKGROUND: For women of refugee background, the increased risk of mental illness associated with pregnancy is compounded by pre- and post-settlement stressors. In Australia, antenatal screening for depression and anxiety symptoms using the Edinburgh Postnatal Depression Scale is recommended for all women. Despite this, screening is not routinely implemented and little is known about barriers and enablers to implementation for women of refugee background. METHODS: Semi-structured interviews were conducted with a range of health professionals (n = 28: midwives, obstetricians, perinatal mental health and refugee health experts, interpreters) and women of refugee background (n = 9)...

Age-related macular degeneration in its neovascular form (NV AMD) is the leading cause of vision loss among adults above the age of 60. Epidemiological data suggest that in men, overall abdominal obesity is the second most important environmental risk factor after smoking for progression to late-stage NV AMD To date, the mechanisms that underscore this observation remain ill-defined. Given the impact of high-fat diets on gut microbiota, we investigated whether commensal microbes influence the evolution of AMD Using mouse models of NV AMD, microbiotal transplants, and other paradigms that modify the gut microbiome, we uncoupled weight gain from confounding factors and demonstrate that high-fat diets exacerbate choroidal neovascularization (CNV) by altering gut microbiota...

Fifty-five years after the concept of dopamine replacement therapy was introduced, Parkinson disease (PD) remains an incurable neurological disorder. To date, no disease-modifying therapeutic has been approved. The inability to predict PD incidence risk in healthy adults is seen as one limitation in drug development, because by the time of clinical diagnosis >60% of dopamine neurons have been lost. We have designed an incidence prediction model founded on the concept that the pathogenesis of PD is similar to that of many disorders observed in ageing humans, i...

BACKGROUND: Global prioritization of single-disease eradication programs over improvements to basic diagnostic capacity in the Global South have left the world unprepared for epidemics of chikungunya, Ebola, Zika, and whatever lies on the horizon. The medical establishment is slowly realizing that in many parts of sub-Saharan Africa (SSA), particularly urban areas, up to a third of patients suffering from acute fever do not receive a correct diagnosis of their infection. MAIN BODY: Malaria is the most common diagnosis for febrile patients in low-resource health care settings, and malaria misdiagnosis has soared due to the institutionalization of malaria as the primary febrile illness of SSA by international development organizations and national malaria control programs...

This paper examined care-seeking behaviour and its associated risk factors when a family member had diarrhoea. Data was obtained from a survey conducted in Chikwawa, a district in Southern Malawi. Chikwawa is faced with a number of environmental and socioeconomic problems and currently diarrhoea morbidity in the district is estimated at 24.4%, statistically higher than the national average of 17%. Using hierarchically built data from a survey of 1403 households nested within 33 communities, a series of two level binary logistic regression models with Bayesian estimation were used to determine predictors of care-seeking behaviour...

Background: Health care needs of mentally ill patients make special demands on cross-sectoral health care structures. § 64b SGB V enables care of mentally ill patients through model projects that are multi-professional, work across treatment periods and sectors and implement new forms of financing. These model projects in their hospitals (case hospitals) need to be evaluated and compared with standard treatment methods. Objectives: The aim of this analysis is to identify matching hospitals according to a priori defined criteria for the establishment of a control group (control hospitals) using secondary data...

BACKGROUND: Autism spectrum disorder (ASD) is a common neurodevelopmental disorder that tends to co-occur with other diseases, including asthma, inflammatory bowel disease, infections, cerebral palsy, dilated cardiomyopathy, muscular dystrophy, and schizophrenia. However, the molecular basis of this co-occurrence, and whether it is due to a shared component that influences both pathophysiology and environmental triggering of illness, has not been elucidated. To address this, we deploy a three-tiered transcriptomic meta-analysis that functions at the gene, pathway, and disease levels across ASD and its co-morbidities...

BACKGROUND: Patients with co-existence of psychiatric disorders and substance use have an increased risk of premature death. This is attributable to a higher prevalence of physical comorbidities and a lifestyle related to substance use. Furthermore, they experience low quality-of-life (QoL). Studies addressing lifestyle interventions for these patients are warranted. AIMS: To investigate the physical health and QoL in patients with co-existence of psychiatric disorders and substance use, and to analyse for changes in their (a) health, (b) substance use, and (c) QoL after a 24-month health-promotion programme...
