Canada's Defence Intelligence Toolkit

On November 22, 2022, Lane Anker, Acting Assistant Chief of Defence Intelligence (ACDI) Canadian Forces Intelligence Command (CFINTCOM), presented on Canada's Defence Intelligence Toolkit. The key points discussed were the role and structure of CFINTCOM, the major global disruption points impacting Canada, and the means available to Canadian defence intelligence to address these challenges.

Hybridization of Atlantic puffins in the Arctic coincides with 20th-century climate change

The Arctic is experiencingthe fastest rates of globalwarming,leadingto shiftsin the distributionof its biotaandincreasingthe potentialfor hybridization. However, genomicevidenceof recenthybridization events in theArctic remainsunexpectedlyrare. Here, we use whole-genomesequencingof contemporary and 122-year-oldhistoricalspecimensto investigate the originof an Arctic hybridpopulation of Atlanticpuffins(Fr aterculaarctica)on Bjørnøya, Norway. We show that the hybridization between the High Arctic, large-bodiedsubspeciesF. a. naumanniand the temperate, smaller-sizedsubspeciesF. a. arcticabeganas recentlyas six generationsagodue to an unexpectedsouthward rangeexpansionofF. a. naumanni.Moreover, we find a significanttemporalloss of geneticdiversityacross Arctic and temperate puffinpopulations.Our observationsprovide compellinggenomicevidenceof the impacts of recentdistributionalshiftsand loss of diversityin Arctic communitiesduringthe 20th century.publishedVersio

EHRA expert consensus document on the management of arrhythmias in frailty syndrome, endorsed by the Heart Rhythm Society (HRS), Asia Pacific Heart Rhythm Society (APHRS), Latin America Heart Rhythm Society (LAHRS), and Cardiac Arrhythmia Society of Southern Africa (CASSA)

There is an increasing proportion of the general population surviving to old age with significant chronic disease, multimorbidity, and disability. The prevalence of pre-frail state and frailty syndrome increases exponentially with advancing age and is associated with greater morbidity, disability, hospitalization, institutionalization, mortality, and health care resource use. Frailty represents a global problem, making early identification, evaluation, and treatment to prevent the cascade of events leading from functional decline to disability and death, one of the challenges of geriatric and general medicine. Cardiac arrhythmias are common in advancing age, chronic illness, and frailty and include a broad spectrum of rhythm and conduction abnormalities. However, no systematic studies or recommendations on the management of arrhythmias are available specifically for the elderly and frail population, and the uptake of many effective antiarrhythmic therapies in these patients remains the slowest. This European Heart Rhythm Association (EHRA) consensus document focuses on the biology of frailty, common comorbidities, and methods of assessing frailty, in respect to a specific issue of arrhythmias and conduction disease, provide evidence base advice on the management of arrhythmias in patients with frailty syndrome, and identifies knowledge gaps and directions for future research

Medicinal importance of grapefruit juice and its interaction with various drugs

Grapefruit juice is consumed widely in today's health conscious world as a protector against cardiovascular diseases and cancers. It has however, been found to be an inhibitor of the intestinal cytochrome P – 450 3A4 system, which is responsible for the first pass metabolism of many drugs. The P – glycoprotein pump, found in the brush border of the intestinal wall which transports many of these cytochrome P – 450 3A4 substrates, has also been implicated to be inhibited by grapefruit juice. By inhibiting these enzyme systems, grapefruit juice alters the pharmacokinetics of a variety of medications, leading to elevation of their serum concentrations. Most notable are its effects on the calcium channel antagonist and the statin group of drugs. In the case of many drugs, the increased serum concentration has been found to be associated with increased frequency of dose dependent adverse effects. In this review, we have discussed the phytochemistry of grapefruit juice, the various drugs involved in the drug – grapefruit juice eraction with their mechanisms of action and have presented the clinical implications of these interactions
