Olga Koubrak: Protecting the Caribbean Sawfish
Student editor Patrick Sheppard sits down with Professor Olga Koubrak of the Schulich School of Law to discuss her work on the legal frameworks to protect sawfish in the Caribbean. Olga is the author of a 2018 paper titled “A Future for a Forgotten Predator: An Assessment of International Legal Frameworks for Protection and Recovery of the Caribbean Sawfishes,” and co-author of the more recent 2022 article titled “Strengthening Marine Species Protections in Cuba: A Case Study on the Critically Endangered Smalltooth Sawfish.” Patrick and Olga discuss the sawfish, means of protecting the animal domestically and internationally, problems in enforcement and international cooperation, and how the public perception of an animal affects how it is protected by authorities.

The space in the literary work of Olga Tokarczuk
The article presents and analyses types of space existing in the literary output of Olga Tokarczuk. The author focuses on exploring two triple divisions of this phenomenon. First division deals with an area understood as both open and closed sites, and objects. The second division distinguishes realistic space (specific events and places), internal (a hero’s psychology and a relationship between a human being and a place) and mythical (placing reality in myth)

Blood pressure response to standing is a strong determinant of masked hypertension in young to middle-age individuals
Reproducibility of daytime hypertension, night-time hypertension, and nocturnal blood pressure dipping patterns in young to middle age patients with stage 1 hypertension
Objective: To investigate the reproducibility of ambulatory BP sub-periods and nocturnal dipping phenotypes assessed twice 3 months apart in young-to-middle-age untreated individuals screened for stage 1 hypertension. Design and methods: We investigated 1096, 18-to-45-year old participants from the HARVEST. Their office BP was 145.8 ± 10.4/93.7 ± 5.7 mmHg. Office BP and 24 h BP were measured at baseline and after 3 months. Office, 24-h, daytime and night-time hypertensions, and nocturnal dipping patterns were defined according to the 2023 ESH guidelines. Between-recording agreement was evaluated with kappa statistics. Results: Reproducibility evaluated with weighted kappa was moderate for both 24 h hypertension (K = 0.48) and daytime hypertension (K = 0.50) and was only fair for night-time hypertension (K = 0.36). Between-measurement agreement was even worse for isolated night-time hypertension (K = 0.24), and was poor for office hypertension (K = 0.14). The better reproducibility of daytime than night-time period was confirmed by the analysis of BP as continuous variable (all between-period differences, P < 0.001). Nondipping was present in 31.8%, and showed a fair agreement (K = 0.28,). Poorer agreement was shown by extreme dipping (K = 0.18) and reverse dipping (K = 0.07). Conclusions: These data show that within the ambulatory sub-periods, daytime hypertension has a better reproducibility than night-time hypertension. This suggests that the better association with adverse outcomes shown by sleep BP compared to wake BP in observational studies is not due to a better reproducibility of the former. The between-measurement agreement is even worse for isolated nocturnal hypertension and dipping patterns, especially for extreme and reverse dipping. Thus, these BP phenotypes should be confirmed with repeat ambulatory BP monitoring
Dipping pattern and short-term blood pressure variability are stronger predictors of cardiovascular events than average 24-hour blood pressure in young hypertensive subjects
Aims The role of increased blood pressure (BP) variability and a blunted day-night BP drop is still being debated, particularly in young hypertensive subjects. We investigated the contribution of BP variability and day-night BP changes combined to cardiovascular events in initially untreated young hypertensive individuals. Methods and results We selected 1794 subjects aged <= 45 years from the HARVEST and the PIUMA studies, two long-term observational studies in subjects with hypertension. The outcome was a composite pool of non-fatal myocardial infarction or stroke, heart failure needing hospitalization, death from cardiovascular causes, and myocardial or limb revascularization procedures. During an 11.3-year follow-up, 140 cardiovascular events were accrued. A multivariable Cox model which included BP variability and non-dipping was more informative (Akaike Information Criterion = 1536.9) than the model which included average of 24-h BP (Akaike Information Criterion = 1553.6). A higher hazard ratio (HR) was observed for non-dipping [HR 2.22; 95% confidence interval (CI): 1.55-3.17; P < 0.0001] and for high BP variability (HR 1.84; 95% CI: 1.26-2.65; P = 0.0015) than for high average 24-h BP (HR 1.58; 95% CI: 1.07-2.33; P = 0.020). When average 24-h ambulatory BP was included in a nested model, the -2log likelihood decreased from 1524.9 to 1519.3, and there was a tendency for an interactive effect between 24-h BP and non-dipping on risk of cardiovascular events (P = 0.092). Conclusion In young hypertensive individuals, prognostic models including BP variability and non-dipping pattern provide better information than models with average 24-h ambulatory BP alone. More consideration should be given to BP variability and the day-night BP pattern beyond the average 24-h ambulatory BP in young hypertensive subjects
