Schizophrenia is a debilitating psychiatric condition often associated with poor quality of life and decreased life expectancy. Lack of progress in improving treatment outcomes has been attributed to limited knowledge of the underlying biology, although large-scale genomic studies have begun to provide insights. We report a new genome-wide association study of schizophrenia (11,260 cases and 24,542 controls), and through meta-analysis with existing data we identify 50 novel associated loci and 145 loci in total...

Toronto has the largest absolute number of food insecure households for any metropolitan census area in Canada: of its 2.1 million households, roughly 252 000 households (or 12%) experience some level of food insecurity. Community organizations (including social agencies, school programs, and child care centres) serve millions of meals per year to the city's most vulnerable citizens, but often face challenges accessing fresh produce at affordable prices. Therefore in 2015, Toronto Public Health, in collaboration with public- and private-sector partners, launched the FoodReach program to improve the efficiency of food procurement among community organizations by consolidating their purchasing power...

Human corneal endothelial cells (HCEnCs) are terminally differentiated cells that have limited regenerative potential. The large numbers of mitochondria in HCEnCs are critical for pump and barrier function required for corneal hydration and transparency. Fuchs Endothelial Corneal Dystrophy (FECD) is a highly prevalent late-onset oxidative stress disorder characterized by progressive loss of HCEnCs. We previously reported increased mitochondrial fragmentation and reduced ATP and mtDNA copy number in FECD. Herein, carbonyl cyanide m-chlorophenyl hydrazone (CCCP)-induced mitochondrial depolarization decreased mitochondrial mass and Mfn2 levels, which were rescued with mitophagy blocker, bafilomycin, in FECD...

PURPOSE: To evaluate whether donor and/or recipient diabetes status affects the outcomes of Descemet membrane endothelial keratoplasty (DMEK). METHODS: A consecutive, single-center DMEK case series was reviewed. The outcome measures were success of surgeon tissue preparation, air reinjection rate, Kaplan-Meier 4-year graft replacement/failure rate for any reason, and endothelial cell loss. RESULTS: The donor had a history of diabetes in 504 of 1791 cases (28%) and the recipient in 14%...

PURPOSE: To describe the recurrence of granular corneal dystrophy type 1 (GCD1) after penetrating keratoplasty (PKP), anterior lamellar keratoplasty (ALK), deep anterior lamellar keratoplasty (DALK), and phototherapeutic keratectomy (PTK) in a single population. The time required to achieve best-corrected visual acuity (BCVA) after each intervention was also analyzed. METHODS: Retrospective review of all patients with GCD1 from a single center between 1989 and 2016...

Endothelial keratoplasty (EK) has revolutionized corneal transplant surgery by providing rapid visual recovery and improved visual outcomes. In parts of the world with Fuchs endothelial dystrophy, many patients may present with both cataracts and corneal degeneration requiring surgery. Other forms of endothelial decompensation may also present with cataracts. The staging or combination of transplant surgery and cataract surgery depend on both the abilities of the surgeon and the surgical techniques being considered...

Endothelial keratoplasty (EK) has revolutionized treatment of corneal endothelial dysfunction. Compared with penetrating keratoplasty (PK), EK provides faster and more reliable visual rehabilitation while maintaining the eye's structural integrity. The number of EK procedures is growing annually and surpassed PK in the United States in 2012. The most widely used iteration, Descemet stripping endothelial keratoplasty (DSEK), implants healthy donor endothelium, Descemet membrane, and posterior stroma. Descemet membrane endothelial keratoplasty (DMEK) eliminates the donor stromal layer...

Little is known about the price sensitivity of demand for home care of the disabled elderly. We partially fill this knowledge gap by using administrative data on the beneficiaries of the main French home care subsidy program in a department and exploiting interindividual variation in provider prices. We address the potential endogeneity of prices by taking advantage of the unequal spatial coverage of providers and instrumenting price by the number of municipalities served by a provider. We estimate a price elasticity of around -0...

PURPOSE: To examine the stability of postmortem glycated hemoglobin (HbA1c) measurement and its relationship to premortem glycemia. METHODS: Postmortem blood samples were obtained from 32 donors (8 known diabetic) and shipped on ice to a central laboratory to examine the stability of HbA1c measurements during the first 9 postmortem days. Thirty-nine other suspected diabetic donors underwent comparison of premortem and postmortem HbA1c measurements. RESULTS: Postmortem HbA1c measurements remained stable after 9 postmortem days (all measurements within ±0...

The price volatility of fossil resources, the uncertainty of their long-term availability and the environmental, climatic and societal problems posed by their operation lead to the need of an energy transition enabling the development and utilization of other alternative and sustainable resources. Acknowledging that indirect land-use change can increase greenhouse gas emission, the European Union (EU) has reshaped its biofuel policy. It has set criteria for sustainability to ensure that the use of biofuels guarantees real carbon savings and protects biodiversity...

The advent of interferon-free direct-acting antiviral therapy for hepatitis C virus (HCV) infection has heightened discussion of treatment as prevention. Rapid scale-up in many settings, and the prospect of further treatment simplification have extended therapeutic optimism towards HCV elimination. However, questions remain regarding the feasability of HCV treatment as prevention, including real world efficacy of direct-acting antiviral therapy, particularly among people who inject drugs, and whether expanded treatment access will be sufficient to reduce HCV transmission...

The structure of the cornea is vital to its transparency, and dystrophies that disrupt corneal organization are highly heritable. To understand the genetic aetiology of Fuchs endothelial corneal dystrophy (FECD), the most prevalent corneal disorder requiring transplantation, we conducted a genome-wide association study (GWAS) on 1,404 FECD cases and 2,564 controls of European ancestry, followed by replication and meta-analysis, for a total of 2,075 cases and 3,342 controls. We identify three novel loci meeting genome-wide significance (P<5 × 10(-8)): KANK4 rs79742895, LAMC1 rs3768617 and LINC00970/ATP1B1 rs1200114...
