Impact of Vanessa's Law on the Reporting of Serious Adverse Events: A Retrospective Study Among Antiplatelet Users in a Tertiary-Care Cardiology Centre.

Background: Antiplatelet drugs, such as clopidogrel, ticagrelor, prasugrel, and acetylsalicylic acid, may be associated with a risk of adverse events (AEs). Vanessa's Law was enacted to strengthen regulations to protect Canadians from drug-related side effects (with mandatory reporting of serious adverse events [SAEs]).

Objective: To determine whether Vanessa's Law has led to an increase in SAE reporting among antiplatelet users.

Underreporting of adverse events to health authorities by healthcare professionals: a red flag-raising descriptive study.

Background: An adverse event (AE) is any undesirable medical manifestation in an individual who has received pharmacological treatment. To be considered serious (SAE), it needs to meet minimally one of the severity criteria by Health Canada. The most recent data (2006) suggested that AEs were underreported (<6%) to health authorities.

Causality assessment of adverse drug reaction: A narrative review to find the most exhaustive and easy-to-use tool in post-authorization settings.

Background: The core motive of pharmacovigilance is the detection and prevention of adverse drug reactions (ADRs), to improve the risk-benefit balance of the drug. However, the causality assessment of ADRs remains a major challenge among clinicians, and none of the available tools of causality assessment used for assessing ADRs have been universally accepted.

Objective: To provide an up-to-date overview of the different causality assessment tools.

Impact of COVID-19 on the Prescribing Pattern of Oral Anticoagulants for Atrial Fibrillation After Cardiac Surgery.

Background: Because of logistic challenges associated with the COVID-19 pandemic, direct oral anticoagulants (DOAC) were favored over warfarin in patients presenting postoperative atrial fibrillation (AF) after cardiac surgery in our institution. Considering the limited evidence supporting the use of DOAC in this context, we sought to evaluate the safety and efficacy of this practice change.

Methods: A retrospective study was performed with patients from the Quebec City metropolitan area who were hospitalized at the Institut universitaire de cardiologie et de pneumologie de Québec-Université Laval following cardiac surgery and who required oral anticoagulant (OAC) for postoperative AF.

Reporting Rates of Opioid-Related Adverse Events Since 1965 in Canada: A Descriptive Retrospective Study.

Background: Patients with chronic or acute/postoperative pain frequently use opioids. However, opioids may cause considerable adverse reactions (ARs), such as respiratory depression, which could be lethal. Unfortunately, only 5% of drug-related ARs (including those to opioids) are reported to health authorities.

Long-Term Retrospective Analysis of Gene Therapy with Alipogene Tiparvovec and Its Effect on Lipoprotein Lipase Deficiency-Induced Pancreatitis.

Alipogene tiparvovec (Glybera) is a gene therapy product approved in Europe under the "exceptional circumstances" pathway as a treatment for lipoprotein lipase deficiency (LPLD), a rare genetic disease resulting in chylomicronemia and a concomitantly increased risk of acute and recurrent pancreatitis, with potentially lethal outcome. This retrospective study analyzed the frequency and severity of pancreatitis in 19 patients with LPLD up to 6 years after a single treatment with alipogene tiparvovec. An independent adjudication board of three pancreas experts, blinded to patient identification and to pre- or post-gene therapy period, performed a retrospective review of data extracted from the patients' medical records and categorized LPLD-related acute abdominal pain events requiring hospital visits and/or hospitalizations based on the adapted 2012 Atlanta diagnostic criteria for pancreatitis.

Immune responses to intramuscular administration of alipogene tiparvovec (AAV1-LPL(S447X)) in a phase II clinical trial of lipoprotein lipase deficiency gene therapy.

Cellular immune responses to adeno-associated viral (AAV) vectors used for gene therapy have been linked to attenuated transgene expression and loss of efficacy. The impact of such cellular immune responses on the clinical efficacy of alipogene tiparvovec (Glybera; AAV1-LPL(S447X); uniQure), a gene therapy consisting of intramuscular administration of a recombinant AAV1 mediating muscle-directed expression of lipoprotein lipase (LPL), was investigated. Five subjects with LPL deficiency (LPLD) were administered intramuscularly with a dose of 1 × 10(12) gc/kg alipogene tiparvovec.

Gene therapy for lipoprotein lipase deficiency.

Purpose Of Review: The present review summarizes the clinical development of adeno-associated viral vector (AAV)1-lipoprotein lipase (LPL)S447X gene therapy (alipogene tiparvovec) for lipoprotein lipase deficiency. Lipoprotein lipase deficiency is a rare inherited disease characterized by severe hypertriglyceridaemia, chylomicronaemia and risk of recurrent pancreatitis or other complications. AAV1-LPLS447X gene therapy is based on the rationale that by adding episomal copies of functional LPL genes into muscle cells lacking active LPL, metabolic function could be improved or restored.

Salivary pH as a marker of plasma adiponectin concentrations in Women.

Background: Plasma adiponectin is a significant correlate of the pro-inflammatory cardiometabolic risk profile associated with obesity and type 2 diabetes. Salivary pH is influenced by several cardiometabolic risk components such as inflammation, oxidation and numerous oral and systemic health modulators, including the menopausal status. This study aimed to assess the association between plasma adiponectin concentrations and salivary pH in women according to the menopausal status.

On-site management of investigational products and drug delivery systems in conformity with Good Clinical Practices (GCPs).

Background: Investigators and research teams participating in clinical trials have to deal with complex investigational products, study designs, and research environments. The emergence of new drug delivery systems and investigational products combining more than one drug and the development of biodrugs such as monoclonal antibodies, peptides, siRNA, and gene therapy to treat orphan or common diseases constitute a new challenge for investigators and clinical sites.

Purpose: We describe the requirements and challenges of drug management in conformity with Good Clinical Practices (GCPs) for investigators and sites participating in clinical trials.

Etiology and risk of lactescent plasma and severe hypertriglyceridemia.

Background: Plasma lactescence is a clinical sign of severe hypertriglyceridemia (hyperTG; TG >10 mmol/L), which is likely to be observed more frequently in the next decades because of the growing prevalence of obesity and diabetes worldwide.

Objective: The objective of this study was to describe the clinical expression of plasma lactescence.

Methods: A total of 354 subjects with lactescent plasma hyperTG (mean TG ± SD: 17.

Contribution of adiponectin to the cardiometabolic risk of postmenopausal women with loss-of-function lipoprotein lipase gene mutations.

Objective: Cardiovascular risk significantly increases after menopause. Lipoprotein lipase (LPL) is a key enzyme in the metabolism of triglyceride (TG)-rich lipoproteins, which contributes to cardiometabolic homeostasis. Adiponectin is an adipocytokine, which also influences the cardiometabolic status.

Comparison of the efficacy of fibrates on hypertriglyceridemic phenotypes with different genetic and clinical characteristics.

Unlabelled: Hypertriglyceridemia is a frequent and heterogeneous clinical trait, which modulates the risk of disease. Fibrates constitute an effective class of triglyceride-lowering agents.

Objective: To evaluate the effect of fibrates on fasting plasma triglycerides and other lipids levels in hypertriglyceridemia phenotypes with different genetic and clinical characteristics.

Review of the clinical development of alipogene tiparvovec gene therapy for lipoprotein lipase deficiency.

Alipogene tiparvovec (AAV1-LPL(S447X)) gene therapy is developed to prevent complications and decrease the clinical morbidity of lipoprotein lipase deficiency (LPLD). LPLD is an autosomal recessive disease associated with severe hypertriglyceridemia (hyperTG), severe chylomicronaemia, and low HDL. Acute pancreatitis, the most frequent serious clinical LPLD complication, is a complex and heterogeneous inflammatory condition having many causes including hyperTG and chylomicronaemia.

The ACE-DD genotype is associated with endothelial dysfunction in postmenopausal women.

Objective: To evaluate the effects of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D), the angiotensinogen M235T and the angiotensin II type 1 receptor A1166C polymorphisms, and hormone therapy used on endothelial function in postmenopausal women without manifestation of coronary artery disease.

Design: Sixty-four postmenopausal women (42 hormone therapy users and 22 hormone therapy nonusers) without clinical manifestation of coronary artery disease were evaluated using external vascular ultrasonography to measure endothelium-dependent (hyperemic response, flow-mediated dilatation) and -independent (nitroglycerin) dilatation. Genotypes were determined by polymerase chain reaction amplification.

ACE-DD genotype is associated with the occurrence of acute coronary syndrome in postmenopausal women.

The insertion/deletion (I/D) polymorphism of the angiotensin converting enzyme (ACE), the A1166C polymorphism in the angiotensin type 1 receptor (AT1R), and the M235T polymorphism of the angiotensinogen gene are associated with cardiovascular disease mostly in men. Few data are available on the effects of these genetic variations in postmenopausal women according to hormone replacement therapy (HRT) use. In this case-control study, we determine the frequency of mutant alleles in the ACE I/D, M235T and A1166C polymorphisms in postmenopausal Caucasian women with and without a diagnosis of acute coronary syndrome (ACS).

Does hormonal status influence the clinical presentation of acute coronary syndromes in women?

Background: Previous studies suggest that the clinical presentation of acute coronary syndromes (ACS) may differ between women and men. It is not known if different clinical presentations may be explained by hormonal status in women with ACS. Our objective was to compare the clinical presentation of ACS between premenopausal (PRE) women and post-menopausal women with hormone replacement therapy (HRT) and without (POST).
