Reading Camps and Travelling Libraries in New Ontario, 1900-1905

AbstractIn 1900, the Ontario Department of Education and Alfred Fitzpatrick engaged in an experiment to supply books to reading camps for lumber, mining, and railway workers in Northern Ontario. The center-periphery interplay between education officials and Fitzpatrick gave birth to two important adult education agencies: Frontier College and Ontario’s travelling library system. Although the Department partially accepted Fitzpatrick’s original plan for library extension, he garnered enough public support and employer endorsements to leverage government action on key issues related to a systematic book supply, the reduction of illiteracy, and non-formal adult learning techniques. This paper uses primary sources to examine the differing objectives held by Fitzpatrick and the Department during their initial joint venture prior to the Ontario election of 1905. The study highlights why travelling libraries became a provincial responsibility; as well, it shows Fitzpatrick reshaped his original plans by practical interactions with resource workers that led to new approaches for adult learning at the outset of the 20th century.RésuméEn 1900, le Département de l’éducation de l’Ontario et Alfred Fitzpatrick se lancent dans une expérience : celle d’approvisionner en livres les camps des travailleurs forestiers, des mines et des chemins de fer dans le Nord ontarien. Cette interaction « centre-périphérie », des fonctionnaires et de Fitzpatrick, a donné naissance à deux agences importantes d’éducation aux adultes : le Frontier College et le système ontarien de bibliothèques ambulantes. Bien que le Département ait accepté partiellement le plan originel de Fitzpatrick pour l’expansion du système de bibliothèques, ce dernier a pu compter sur un soutien suffisant de la part du public et des employeurs pour motiver le gouvernement à agir sur des questions clés comme l’approvisionnement en livres, la diminution de l’analphabétisme et l’application de techniques d’apprentissage non-formelles pour les adultes. Cet article s’appuie sur des sources primaires afin d’examiner les objectifs divergents de Fitzpatrick et du Département au début de leur entreprise commune, et ce, avant l’élection provinciale de 1905. L’auteur expose pourquoi les bibliothèques ambulantes sont passées sous la responsabilité provinciale. Il montre également que Fitzpatrick a adapté ses plans originaux à la suite d’interactions avec des travailleurs-ressources qui menèrent à de nouvelles approches en éducation aux adultes au début du vingtième siècle

The Carnegie Corporation Advisory Group on Canadian College Libraries, 1930–35

The Carnegie Corporation of New York (CCNY) contributed signi cantly to the development of Canadian university and college libraries during the Great Depression. From 1932 to 1935, thirty-four institutions of higher education shared in library book grants totalling $214,800 as a result of a national (Canada and Newfoundland) examination conducted by an advisory group established by the CCNY. The ways in which the advisory group investigated and inspected potential recipients, evaluated whether they complied with conditions set, and distributed grants typically followed the policies and procedures established by an earlier American advisory group funded by the CCNY. Carnegie and university records document how nancial aid was awarded and used for the advancement of undergraduate print collections. Sources can also be used to study the Canadian group in relation to the role of American philanthropic college library work, attempts by Canadian administrators to adapt library collections and organization to local circumstances, and trends in the improvement of undergraduate library services on a national scale. RÉSUMÉ L’organisme The Carnegie Corporation of New York (CCNY) a contribué d’une manière signi- cative au développement des bibliothèques des universités et des collèges canadiens durant la grande dépression. De 1932 à 1935, trente-quatre institutions d’éducation supérieure se sont partagé des octrois totalisant 214 800$ pour l’achat de livres. Ce montant a été établi lors d’une enquête nationale menée conjointement au Canada et à Terre-Neuve par un groupe de travail consultatif établi par le CCNY. Les manières de procéder de ce comité quant à l’inves- tigation et à la surveillance des institutions récipiendaires, l’évaluation du respect des conditions xées ainsi que la distribution des subventions s’appuient sur les politiques et procédures établies précédemment par un comité consultatif américain créé par le CCNY. Les documents provenant de la corporation Carnegie et des universités exposent comment l’aide nancière était accordée et utilisée pour l’enrichissement des collections des imprimés pour les étudiants du premier cycle. Ces sources peuvent aussi servir à étudier les relations du groupe canadien avec la philanthropie américaine en regard des bibliothèques. D’autres questions comme les tentatives des administrateurs canadiens pour harmoniser les collections des bibliothèques et les adapter aux besoins spéci ques de leur milieu, ainsi que la tendance à améliorer les services fournis par les bibliothèques aux étudiants de premier cycle à l’échelle canadienne, pourraient faire l’objet d’études ultérieures.

Ozanimod in relapsing multiple sclerosis : Pooled safety results from the clinical development program

Background: Ozanimod, an oral sphingosine 1-phosphate receptor 1 and 5 modulator, is approved in multiple countries for the treatment of relapsing multiple sclerosis (RMS). In phase 3 trials, ozanimod was well tolerated and superior to interferon beta-1a 30 µg once-weekly in reducing clinical and radiologic disease activity. The objective of this integrated safety analysis was to evaluate the safety of extended ozanimod exposure in participants with RMS from all clinical trials and compare it with phase 3 trial data. Methods: We report pooled incidence and study duration‒adjusted incidence rates (IR) of treatment-emergent adverse events (TEAEs) from an interim data cut (January 31, 2019) of RMS participants treated with ozanimod. Data were pooled from a phase 1 pharmacokinetic/pharmacodynamic trial, a placebo-controlled phase 2 trial with dose-blinded extension, 2 large active-controlled phase 3 trials, and an open-label extension (OLE). Results were compared with pooled phase 3 trial data. Results: At the data cutoff, 2631 RMS participants had exposure to ozanimod 0.92 mg (mean 32.0 months) and 2787 had exposure to either ozanimod 0.46 or 0.92 mg (mean 37.1 months). The IRs per 1000 person-years (PY) for any TEAE (772.2) and serious TEAEs (33.2) in the overall population were similar to those in the phase 3 population (896.1 and 31.2, respectively). There were no serious opportunistic infections. There were no second-degree or higher atrioventricular blocks on electrocardiogram. Hepatic enzyme elevations declined over time. Malignancy rates remained low with longer exposure. Pulmonary function tests showed minimal reductions in lung function. Seven ozanimod-treated participants with comorbid risk factors had confirmed macular edema, including 3 in the ongoing OLE. Conclusions: Safety results in this larger RMS population with greater ozanimod exposure demonstrated no new safety concerns and were consistent with phase 3 trial results

Long-term safety and efficacy of ozanimod in relapsing multiple sclerosis : Up to 5 years of follow-up in the DAYBREAK open-label extension trial

Background: Ozanimod, an oral sphingosine 1-phosphate receptor 1 and 5 modulator, is approved in multiple countries for treatment of relapsing forms of MS. Objective: To characterize long-term safety and efficacy of ozanimod. Methods: Patients with relapsing MS who completed a phase 1‒3 ozanimod trial were eligible for an open-label extension study (DAYBREAK) of ozanimod 0.92 mg/d. DAYBREAK began 16 October 2015; cutoff for this interim analysis was 2 February 2021. Results: This analysis included 2494 participants with mean 46.8 (SD 11.9; range 0.033‒62.7) months of ozanimod exposure in DAYBREAK. During DAYBREAK, 2143 patients (85.9%) had treatment-emergent adverse events (TEAEs; similar in nature to those in the parent trials), 298 (11.9%) had a serious TEAE, and 75 (3.0%) discontinued treatment due to TEAEs. Serious infections (2.8%), herpes zoster infections (1.7%), confirmed macular edema cases (0.2%), and cardiac TEAEs (2.8%) were infrequent. Adjusted annualized relapse rate was 0.103 (95% confidence interval, 0.086‒0.123). Over 48 months, 71% of patients remained relapse free. Adjusted mean numbers of new/enlarging T2 lesions/scan and gadolinium-enhancing lesions were low and similar across parent trial treatment subgroups. Conclusions: This long-term extension of ozanimod trials confirmed a favorable safety/tolerability profile and sustained benefit on clinical and magnetic resonance imaging measures of disease activity

Downregulation of exosomal miR-204-5p and miR-632 as a biomarker for FTD: a GENFI study.

OBJECTIVE: To determine whether exosomal microRNAs (miRNAs) in cerebrospinal fluid (CSF) of patients with frontotemporal dementia (FTD) can serve as diagnostic biomarkers, we assessed miRNA expression in the Genetic Frontotemporal Dementia Initiative (GENFI) cohort and in sporadic FTD. METHODS: GENFI participants were either carriers of a pathogenic mutation in progranulin, chromosome 9 open reading frame 72 or microtubule-associated protein tau or were at risk of carrying a mutation because a first-degree relative was a known symptomatic mutation carrier. Exosomes were isolated from CSF of 23 presymptomatic and 15 symptomatic mutation carriers and 11 healthy non-mutation carriers. Expression of 752 miRNAs was measured using quantitative PCR (qPCR) arrays and validated by qPCR using individual primers. MiRNAs found differentially expressed in symptomatic compared with presymptomatic mutation carriers were further evaluated in a cohort of 17 patients with sporadic FTD, 13 patients with sporadic Alzheimer's disease (AD) and 10 healthy controls (HCs) of similar age. RESULTS: In the GENFI cohort, miR-204-5p and miR-632 were significantly decreased in symptomatic compared with presymptomatic mutation carriers. Decrease of miR-204-5p and miR-632 revealed receiver operator characteristics with an area of 0.89 (90% CI 0.79 to 0.98) and 0.81 (90% CI 0.68 to 0.93), respectively, and when combined an area of 0.93 (90% CI 0.87 to 0.99). In sporadic FTD, only miR-632 was significantly decreased compared with AD and HCs. Decrease of miR-632 revealed an area of 0.90 (90% CI 0.81 to 0.98). CONCLUSIONS: Exosomal miR-204-5p and miR-632 have potential as diagnostic biomarkers for genetic FTD and miR-632 also for sporadic FTD

Concerns over use of glyphosate-based herbicides and risks associated with exposures: a consensus statement

Abstract The broad-spectrum herbicide glyphosate (common trade name "Roundup") was first sold to farmers in 1974. Since the late 1970s, the volume of glyphosate-based herbicides (GBHs) applied has increased approximately 100-fold. Further increases in the volume applied are likely due to more and higher rates of application in response to the widespread emergence of glyphosate-resistant weeds and new, pre-harvest, dessicant use patterns. GBHs were developed to replace or reduce reliance on herbicides causing well-documented problems associated with drift and crop damage, slipping efficacy, and human health risks. Initial industry toxicity testing suggested that GBHs posed relatively low risks to non-target species, including mammals, leading regulatory authorities worldwide to set high acceptable exposure limits. To accommodate changes in GBH use patterns associated with genetically engineered, herbicide-tolerant crops, regulators have dramatically increased tolerance levels in maize, oilseed (soybeans and canola), and alfalfa crops and related livestock feeds. Animal and epidemiology studies published in the last decade, however, point to the need for a fresh look at glyphosate toxicity. Furthermore, the World Health Organization's International Agency for Research on Cancer recently concluded that glyphosate is "probably carcinogenic to humans." In response to changing GBH use patterns and advances in scientific understanding of their potential hazards, we have produced a Statement of Concern drawing on emerging science relevant to the safety of GBHs. Our Statement of Concern considers current published literature describing GBH uses, mechanisms of action, toxicity in laboratory animals, and epidemiological studies. It also examines the derivation of current human safety standards. We conclude that: (1) GBHs are the most heavily applied herbicide in the world and usage continues to rise; (2) Worldwide, GBHs often contaminate drinking water sources, precipitation, and air, especially in agricultural regions; (3) The half-life of glyphosate in water and soil is longer than previously recognized; (4) Glyphosate and its metabolites are widely present in the global soybean supply; (5) Human exposures to GBHs are rising; (6) Glyphosate is now authoritatively classified as a probable human carcinogen; (7) Regulatory estimates of tolerable daily intakes for glyphosate in the United States and European Union are based on outdated science. We offer a series of recommendations related to the need for new investments in epidemiological studies, biomonitoring, and toxicology studies that draw on the principles of endocrinology to determine whether the effects of GBHs are due to endocrine disrupting activities. We suggest that common commercial formulations of GBHs should be prioritized for inclusion in government-led toxicology testing programs such as the U.S. National (Continued on next page

Targeted copy number variant identification across the neurodegenerative disease spectrum

Background: Although genetic factors are known to contribute to neurodegenerative disease susceptibility, there remains a large amount of heritability unaccounted for across the diagnoses. Copy number variants (CNVs) contribute to these phenotypes, but their presence and influence on disease state remains relatively understudied. Methods: Here, we applied a depth of coverage approach to detect CNVs in 80 genes previously associated with neurodegenerative disease within participants of the Ontario Neurodegenerative Disease Research Initiative (n = 519). Results: In total, we identified and validated four CNVs in the cohort, including: (1) a heterozygous deletion of exon 5 in OPTN in an Alzheimer\u27s disease participant; (2) a duplication of exons 1–5 in PARK7 in an amyotrophic lateral sclerosis participant; (3) a duplication of \u3e3 Mb, which encompassed ABCC6, in a cerebrovascular disease (CVD) participant; and (4) a duplication of exons 7–11 in SAMHD1 in a mild cognitive impairment participant. We also identified 43 additional CNVs that may be candidates for future replication studies. Conclusion: The identification of the CNVs suggests a portion of the apparent missing heritability of the phenotypes may be due to these structural variants, and their assessment is imperative for a thorough understanding of the genetic spectrum of neurodegeneration
