    Abstract The numbers of organ donors in Canada and the USA fall short of increasing demand, resulting in increased morbidity, poor health outcomes, higher medical costs and death of many individuals waitlisted for transplantation. In the US, since 2013 when the US HIV Organ Policy Equity (HOPE) Act lifted the ban on organ donation between people living with HIV, the option of using organs from People with HIV became a reality. In Canada, HIV diagnosis was an exclusion criterion to organ donation until 2017, when permission was granted if requirements for 'exceptional distribution' could be met. Still, donation of organs from people with HIV poses challenges. Herein, we overview policies involving donors with HIV in Canada in order to inform healthcare providers, researchers and the community. We also advocate for the need to reassess these policies, highlight educational needs and engage interest in advancing research to inform policy reforms.

    Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by low-grade chronic inflammation, which could be exacerbated by type 2 diabetes mellitus (DM). We hypothesized that neutrophils in patients with DM and patients with HFpEF with/without DM contribute to low-grade inflammation through the release of pro-inflammatory cytokines. Venous blood was withdrawn from patients with DM (n = 22), HFpEF (n = 15), HFpEF with DM (n = 13), and healthy controls (CTL) (n = 21). Levels of circulating cytokines and in vitro cytokines released by isolated neutrophils were assessed by enzyme-linked immunosorbent assay. Compared with CTL, there was a significant decrease in circulating nitric oxide in patients with DM (p ≤0.001), HFpEF (p ≤0.05), and HFpEF with DM (p ≤0.001) up to 44%. Circulating soluble intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 levels increased (up to 2.5-fold and 1.9-fold, respectively; p ≤0.001) in patients with HFpEF and patients with HFpEF and DM, whereas soluble E-selectin only increased in patients with HFpEF and DM (1.4-fold, p ≤0.001). Circulating vascular endothelial growth factor levels were similar in CTL and patients with DM but were decreased in patients with HFpEF with/without DM (up to 94%; p ≤0.001). Circulating C-reactive protein, interleukin (IL)-8, IL-6, and IL-receptor antagonist increased in all patient groups with a maximum of 3.3-fold, 4.7-fold, 4.8-fold, and 1.6-fold, respectively, in patients with HFpEF and patients with DM. In vitro, lipopolysaccharide increased neutrophils IL-6 release from HFpEF with DM (3.7-fold; p ≤0.001), and IL-8 release from DM and HFpEF with DM versus CTL (2.8-fold and 10.1-fold, respectively; p ≤0.001). IL-1 receptor antagonist and vascular endothelial growth factor release from HFpEF neutrophils significantly decreased up to 87.0% and 92.2%, respectively, versus CTL. Neutrophils from patients with DM and HFpEF release more cytokines than CTL. This increase in pro-inflammatory status may explain the greater event rate in patients with HFpEF and DM.

    Abstract Mice systemically lacking dipeptidyl peptidase-4 (DPP4) have improved islet health, glucoregulation, and reduced obesity with high-fat diet (HFD) feeding compared to wild-type mice. Some, but not all, of this improvement can be linked to the loss of DPP4 in endothelial cells (ECs), pointing to the contribution of non-EC types. The importance of intra-islet signaling mediated by α to β cell communication is becoming increasingly clear; thus, our objective was to determine if β cell DPP4 regulates insulin secretion and glucose tolerance in HFD-fed mice by regulating the local concentrations of insulinotropic peptides. Using β cell double incretin receptor knockout mice, β cell- and pancreas-specific

    Abstract Few studies have examined preventative behaviour practices with respect to COVID-19 among people living with HIV (human immunodeficiency virus). Using a cross-sectional survey from a Canadian Institutes of Health Research Canadian HIV Trials Network study (CTN 328) of people living with HIV on vaccine immunogenicity, we examined the relationships between participant characteristics and behavioural practices intended to prevent COVID-19 infection. Participants living in four Canadian urban centers were enrolled between April 2021-January 2022, at which time they responded to a questionnaire on preventative behaviour practices. Questionnaire and clinical data were combined to explore relationships between preventive behaviours and (1) known COVID-19 infection pre-enrolment, (2) multimorbidity, (3) developing symptomatic COVID-19 infection, and (4) developing symptomatic COVID-19 infection during the Omicron wave. Among 375 participants, 49 had COVID-19 infection pre-enrolment and 88 post-enrolment. The proportion of participants reporting always engaging in preventative behaviours included 87% masking, 79% physical distancing, 70% limiting social gatherings, 65% limiting contact with at-risk individuals, 33% self-isolating due to symptoms, and 26% self-quarantining after possible exposure. Participants with known COVID-19 infection pre-enrolment were more likely to self-quarantine after possible exposure although asymptomatic (65.0% vs 23.4%, p < 0.001; Chi-square test). Participants with multiple comorbidities more likely endorsed physical distancing (85.7% vs 75.5%, p = 0.044; Chi-square test), although this was not significant in logistic regression analysis adjusted for age, sex, race, number of household members, number of bedrooms/bathrooms in the household per person, influenza immunization, and working in close physical proximity to others. Overall, participants reported frequent practice of preventative behaviours.

    Abstract Aims: Heart failure with reduced ejection fraction (HFrEF) is characterized by sub-clinical inflammation. Changes in selected biomarkers of inflammation concomitant with the release of pro-inflammatory and anti-inflammatory cytokines by neutrophils have not been investigated in patients with HFrEF.
    Methods and results: Fifty-two patients, aged 68.8 ± 1.7 years, with HFrEF and left ventricular ejection fraction 28.7 ± 1.0%, and 21 healthy controls (CTL) were recruited. Twenty-five HF patients had type 2 diabetes. Venous blood samples from HF and CTL were collected once. Neutrophil-derived pro-inflammatory and anti-inflammatory cytokine levels were assessed in plasma by ELISA. Plasma biomarkers assessed included: C-reactive protein (CRP), vascular endothelial growth factor (VEGF), interleukins (IL)-6, -8, -1 receptor antagonist (-1RA), nitric oxide (NO), soluble intercellular adhesion molecule-1 (sICAM-1), vascular cell adhesion molecule 1 (sVCAM-1) and E-Selectin (sE-Sel). Neutrophils were isolated and stimulated with various agonists to promote VEGF, IL-6, IL-8, and IL-1RA release. Compared with CTL, HFrEF patients showed a marked decrease in circulating VEGF [178.0 (interquartile range; IQR 99.6; 239.2) vs. 16.2 (IQR 9.3; 20.2) pg/mL, P ≤ 0.001] and NO [45.2 (IQR 42.1; 57.6) vs. 40.6 (IQR 30.4; 47.1) pg/mL, P = 0.0234]. All other circulating biomarkers were significantly elevated. Neutrophils isolated from patients with HFrEF exhibited a greater IL-8 release in response to LPS [1.2 ± 0.1 (CTL); 10.4 ± 1.6 ng/mL (HFrEF) and 12.4 ± 1.6 ng/mL (HFrEF and DM), P ≤ 0.001]. IL-6 release in response to LPS was not changed in HFrEF patients without diabetes, whereas it was significantly increased in patients with HFrEF and diabetes [46.7 ± 3.9 (CTL) vs. 165.8 ± 48.0 pg/mL (HFrEF), P = 0.1713 and vs. 397.7 ± 67.4 pg/mL (HFrEF and DM), P ≤ 0.001]. In contrast, the release of VEGF and IL-1RA was significantly reduced in HFrEF (VEGF; TNF-α: 38.6 ± 3.1 and LPS: 25.3 ± 2.6 pg/mL; IL1RA; TNF-α: 0.6 ± 0.04 and LPS: 0.3 ± 0.02 ng/mL) compared with CTL (VEGF; TNF-α: 60.0 ± 9.4 and LPS: 41.2 ± 5.9 pg/mL; IL1RA; TNF-α: 3.3 ± 0.2 and LPS: 2.3 ± 0.1 ng/mL).
    Conclusions: Patients with HFrEF exhibit a significant decrease in circulating VEGF. The release of VEGF and both pro-inflammatory and anti-inflammatory cytokines from the stimulated neutrophils is markedly altered in these patients. The clinical significance of these findings deserves further investigation.

    Abstract Background: The natural history of mitral annular calcification (MAC) and risk for developing calcific mitral valve disease (CMVD) have been poorly defined. The aim of this study was to evaluate the progression rate of MAC and of the development of CMVD.
    Methods: Patients with MAC and paired echocardiograms ≥1 year apart between 2005 and 2019 were included. Progression rates from mild or moderate to severe MAC and to CMVD (defined as severe MAC and significant mitral stenosis and/or regurgitation) were assessed, along with potential association with sex.
    Results: A total of 11,605 patients (mean age, 73 ± 10 years; 51% men) with MAC (78% mild, 17% moderate, 5% severe) were included and underwent follow-up echocardiography at 4.2 ± 2.7 years. Among patients with mild or moderate MAC, 33% presented with severe MAC at 10 years. The rate of severe MAC was higher in women than in men (41% vs 24% [P < .001]; hazard ratio, 1.3; P < .001) and in patients with moderate versus mild MAC (71% vs 22% [P < .001]; hazard ratio, 6.1; P < .001). At 10 years, 10% presented with CMVD (4%, 23%, and 60% in patients with mild, moderate, and severe MAC, respectively), which was predicted by female sex (15% vs 5%; P < .0001), even after adjustment for MAC severity (hazard ratio, 1.9; P < .001).
    Conclusion: In this large cohort of patients with MAC, progression to severe MAC was common and frequently resulted in CMVD. Female sex was associated with higher progression rates. MAC and CMVD are expected to dramatically increase as the population ages, highlighting the importance of a better understanding of the pathophysiology of MAC to develop effective preventive medical therapies.

    Abstract Although it is widely recognized that inflammation plays a critical role in the development and pathology of heart failure (HF), very little is known about the involvement of one of the most abundant immune cells in the blood, a primary immune response cell: the neutrophil. This review summarizes the current literature on the role of subclinical inflammation, with a focus on the neutrophil in the pathophysiology of the HF syndrome. Some emerging therapeutic strategies are also discussed.

    Abstract Understanding the roots of Covid-19 vaccine hesitancy in at-risk groups, such as persons living with HIV (PLWH), is of utmost importance. We developed a modified Vaccine Hesitancy Scale (VHS) questionnaire using items from the National Advisory Committee on Immunization Acceptability Matrix. To examine factors associated with receiving COVID-19 vaccine and the link between vaccine attitudes and beliefs with vaccine behavior, PLWH were recruited via social media and community-based organizations (February-May 2022). Descriptive statistics were used to summarize results. Total VHS score was generated by adding Likert scale scores and linear regression models used to compare results between participants who received or did not receive COVID-19 vaccines. Logistic regression models were used to identify factors associated with vaccine uptake. A total of 246 PLWH indicated whether they received a COVID-19 vaccine. 89% received ≥ 1 dose. Mean total VHS(SD) for persons having received ≥ 1 COVID-19 vaccine was 17.8(6.2) vs. 35.4(9.4) for participants not having received any COVID-19 vaccine. Persons who received ≥ 1 dose were significantly older than those who had not received any (48.4 ± 13.8 vs. 34.0 ± 7.7 years, p < 0.0001). The majority of participants considered COVID-19 vaccination important for their health(81.3%) and the health of others(84.4%). Multivariate logistic regression revealed the odds of taking ≥ 1dose were increased 2.4-fold [95% CI 1.6, 3.5] with each increase in age of 10 years (p < 0.0001). Sex and ethnicity were not different between groups. In conclusion, PLWH accept COVID-19 vaccines for both altruistic and individual reasons. With evolving recommendations and increasing numbers of booster vaccines, we must re-examine the needs of PLWH regularly.
