This survey provided insights into what BC health authority staff perceive as important when utilizing a drug information database. Those considering either renewing or initiating a subscription to an online drug information database can use these results to better understand the preferences of health care professionals. Survey respondents ranked dosing information and ease of use as the 2 most important factors in selecting a drug information database. Pharmacists were more particular about using their preferred database than were other health professionals.
Many medications given to children have no commercially available, age-appropriate formulations. This leads to manipulation of dosage forms designed for adults (compounding), which can result in an increased risk of dosing errors and adverse events, lack of medication adherence because of taste issues, and suboptimal dosing with therapeutic failure.

To determine which drugs required compounding for oral administration to children in a Canadian hospital and, for each compounded drug, to determine whether it was available as licensed oral pediatric formulations in the United States or the European Union.

Drugs requiring compounded liquid formulations for oral administration, dispensed from January 1 to December 31, 2015, at a Canadian university-affiliated tertiary pediatric hospital, and prepared in a quantity exceeding 0.5 L per year, were retrospectively identified. The online drug databases of Health Canada, the US Food and Drug Administration, the European Medicines Agency (EMA), and the UK Medicines well as reimbursement policies, to address these unmet needs.
Canada is lagging behind the United States and the European Union in ensuring availability of and access to suitable pediatric formulations. Potential explanations for this gap include small market size, regulatory uncertainties, and reimbursement shortcomings. Steps must be taken to implement pediatric-sensitive regulations and incentives, as well as reimbursement policies, to address these unmet needs.Manufacturers experienced significant disruptions in their operations and demand in 2020, as businesses struggled to cope with COVID-19 and its implications. To control the spread of the virus, governments initiated stay-at-home orders, and many firms were forced to close or limit operations. As a result, there were severe declines in production and employment, both in the United States and in global markets, often at record paces or rivaling the decreases seen in the Great Recession. While activity has started to rebound somewhat in this latest downturn, it will take time for output and hiring to return to pre-recessionary levels-perhaps not until at least 2022-with uncertainties in the outlook pervasive.A hypothesis is proposed that the cytokine storm syndrome, which complicates COVID-19 in some patients, is a consequence of antibody-dependent enhancement of virus infection, which is in turn happens due to a change in dominant antigenic determinants of SARS-CoV-2 S-protein. The antibody-dependent enhancement of virus infection is a phenomenon in which virus-specific antibodies that are not neutralizing enhance the entry of infectious virus into immune cells causing their death. Antibody-dependent enhancement has been reported for different coronaviruses. This phenomenon happens due to a decrease in the binding strength of neutralizing antibodies to the virus, which converts these antibodies into suboptimal-not neutralizing ones. According to our hypothesis, such a decrease in affinity may be associated with a change in the conformation of the viral S-protein. We believe that this conformational change is the major factor in the switching of antibodies affinity, which triggers antibody-dependent enhancement. However, other factors that contribute to antigen drift and antigenic determinant changes may also play a role.The appropriateness of verification of the possible antiviral effect of dinitrosyl iron complexes with thiol-containing ligands as donors of nitrosonium cations (NO+) is argued. There is reason to hope that treatment of the human respiratory tract and lungs with sprayed solutions of dinitrosyl iron complexes with glutathione or N-acetylcysteine (NAC) as NO+ donors during COVID-19 infection can initiate S-nitrosylation of cellular proteases and thereby suppress viral infection.We develop a Bayesian methodology aimed at simultaneously estimating low-rank and row-sparse matrices in a high-dimensional multiple-response linear regression model. We consider a carefully devised shrinkage prior on the matrix of regression coefficients which obviates the need to specify a prior on the rank, and shrinks the regression matrix towards low-rank and row-sparse structures. We provide theoretical support to the proposed methodology by proving minimax optimality of the posterior mean under the prediction risk in ultra-high dimensional settings where the number of predictors can grow sub-exponentially relative to the sample size. A one-step post-processing scheme induced by group lasso penalties on the rows of the estimated coefficient matrix is proposed for variable selection, with default choices of tuning parameters. We additionally provide an estimate of the rank using a novel optimization function achieving dimension reduction in the covariate space. We exhibit the performance of the proposed methodology in an extensive simulation study and a real data example.The potential habitability of known exoplanets is often categorized by a nominal equilibrium temperature assuming a Bond albedo of either ∼0.3, similar to Earth, or 0. CAY10585 As an indicator of habitability, this leaves much to be desired, because albedos of other planets can be very different, and because surface temperature exceeds equilibrium temperature due to the atmospheric greenhouse effect. We use an ensemble of general circulation model simulations to show that for a range of habitable planets, much of the variability of Bond albedo, equilibrium temperature and even surface temperature can be predicted with useful accuracy from incident stellar flux and stellar temperature, two known parameters for every confirmed exoplanet. Earth's Bond albedo is near the minimum possible for habitable planets orbiting G stars, because of increasing contributions from clouds and sea ice/snow at higher and lower instellations, respectively. link2 For habitable M star planets, Bond albedo is usually lower than Earth's because of near-IR H2O absorption, except at high instellation where clouds are important. We apply relationships derived from this behavior to several known exoplanets to derive zeroth-order estimates of their potential habitability. More expansive multivariate statistical models that include currently non-observable parameters show that greenhouse gas variations produce significant variance in albedo and surface temperature, while increasing length of day and land fraction decrease surface temperature; insights for other parameters are limited by our sampling. We discuss how emerging information from global climate models might resolve some degeneracies and help focus scarce observing resources on the most promising planets.The forensic psychiatric expertise of homicide perpetrators is a standard practice in criminal justice matters. Its validity relies heavily on the knowledge, professional experience and methodology of forensic psychiatrist experts. In the present interview, Daniel Zagury, an important figure of forensic psychiatric expertise in France, shares his clinical practice. In addition, he describes his experience with homicide perpetrators, particularly with serial killers and Islamic terrorist attackers on French soil. Finally, he addresses the recurring and crucial controversy of criminal responsibility, or the lack of it, in perpetrators.Seafood could be a solution to meet global food demand that will double by 2050. Seafood includes a wide variety of edible marine organisms, except fish and mammals. These are molluscs, crustaceans, echinoderms and algae. Like any food, seafood can involve hazards transmitted to humans through food, which affect the health of the consumer. These hazards are both biological (viruses, bacteria, parasites) and chemical (toxins, allergens, chemicals, microplastics). The exposure of populations to these hazards through seafood consumption can be notably explained by their mode of production and the dietary habits. Firstly, the sanitary quality of products reflects the quality of the aquatic environment from which they are taken, which can be contaminated by various types of pollution (faecal or chemical, chronic or accidental). The products are then handled, often treated without using additives or chemical preservatives, and finally distributed without any other means of preservation than refrigeration or freezing. Finally, the dietary habits of seafood favour exposure to certain hazards. Seafood safety must be integrated throughout the food chain, under the responsibility shared by all stakeholders. Seafood safety appears to be an emerging public health issue of global scope, because the sea does not stop at borders.
Albinism is a clinically and genetically heterogeneous condition. Despite analysis of the 20 known genes, ~30% patients remain unsolved. We aimed to identify new genes involved in albinism.

We sequenced a panel of genes with known or predicted involvement in melanogenesis in 230 unsolved albinism patients.

We identified variants in the Dopachrome tautomerase (DCT) gene in two patients. link3 One was compound heterozygous for a 14-bp deletion in exon 9 and c.118T>A p.(Cys40Ser). The second was homozygous for c.183C>G p.(Cys61Trp). Both patients had mild hair and skin hypopigmentation, and classical ocular features. CRISPR-Cas9 was used in C57BL/6J mice to create mutations identical to the missense variants carried by the patients, along with one loss-of-function indel. When bred to homozygosity the three mutations revealed hypopigmentation of the coat, milder for Cys40Ser compared with Cys61Trp or the frameshift mutation. Histological analysis identified significant hypopigmentation of the retinal pigmented epithelium (RPE) indicating that defective RPE melanogenesis could be associated with eye and vision defects. DCT loss of function in zebrafish embryos elicited hypopigmentation both in melanophoresand RPE cells.

DCT is the gene for a new type of oculocutaneous albinism that we propose to name OCA8.

Pregnancy loss ranging from spontaneous abortion (SAB) to stillbirth can result from monogenic causes of Mendelian inheritance. This study evaluated the clinical application of exome sequencing (ES) in identifying the genetic etiology for pregnancy loss.

A cohort of 102 specimens from products of conception (POC) with normal karyotype and absence of pathogenic copy-number variants were selected for ES. Abnormality detection rate (ADR) and variants of diagnostic value correlated with SAB and stillbirth were evaluated.

ES detected 6 pathogenic variants, 16 likely pathogenic variants, and 17 variants of uncertain significance favor pathogenic (VUSfp) from this cohort. The ADR for pathogenic and likely pathogenic variants was 22% and reached 35% with the inclusion of VUSfp. The ADRs of SAB and stillbirth were 36% and 33%, respectively. Affected genes included those associated with multisystem abnormalities, neurodevelopmental disorders, cardiac anomalies, skeletal dysplasia, metabolic disorders, and renal diseases.
