Vascular smooth muscle cells (VSMCs) phenotype switching plays a crucial role in vein graft restenosis following coronary artery bypass grafting (CABG) surgery. To discover novel clinically relevant therapeutic targets for vein graft restenosis after CABG, we therefore investigated whether miRNA-18a-5p mediated phenotype switching plays a critical role in the development of vein graft restenosis. We studied miRNA-18a-5p expression in plasma samples of patients with or without vein graft restenosis at 1, 3 and 5 years after coronary artery bypass graft surgery, and in normal vs.

Epidemiology of myocarditis following COVID-19 or influenza and use of diagnostic assessments.

Open Heart

November 2024

Greenberg Division of Cardiology, Department of Medicine, Weill Cornell Medicine, New York, New York, USA.

Article Synopsis
  • Previous studies indicated a higher risk of acute myocarditis after COVID-19 infection, but it was unclear if this risk was greater than after other viral infections like influenza.
  • A retrospective cohort study analyzed health claims in the U.S. to compare myocarditis rates post-COVID-19 and influenza infections, finding increased rates of myocarditis in COVID-19 patients.
  • The study showed that 0.06% of COVID-19 patients were diagnosed with myocarditis compared to 0.02% in influenza patients, suggesting a notable risk increase associated with COVID-19, especially in younger males with cardiac conditions.

Article Synopsis
  • Mothers in Africa face a significantly higher risk of dying from complications after cesarean deliveries compared to high-income countries, primarily due to postpartum hemorrhage (PPH).
  • A survey conducted among anesthesiologists and obstetricians in 140 hospitals across Africa aimed to assess the readiness of these facilities to implement World Health Organization (WHO) guidelines for preventing and treating PPH.
  • The survey found that while many hospitals had access to key medications like oxytocin and crystalloids, there were gaps in the availability of some critical treatments, such as heat-stable carbetocin and intrauterine balloon tamponades, highlighting the need for improved resources and training in PPH management.

Purpose: As part of the 100,000 Genomes Project, we set out to assess the potential viability and clinical impact of reporting genetic variants associated with drug-induced toxicity for patients with cancer recruited for whole-genome sequencing (WGS) as part of a genomic medicine service.

Methods: Germline WGS from 76,805 participants was analyzed for pharmacogenetic (PGx) variants in four genes (, , , ) associated with toxicity induced by five drugs used in cancer treatment (capecitabine, fluorouracil, mercaptopurine, thioguanine, irinotecan). Linking genomic data with prescribing and hospital incidence records, a phenome-wide association study (PheWAS) was performed to identify whether phenotypes indicative of adverse drug reactions (ADRs) were enriched in drug-exposed individuals with the relevant PGx variants.

In human breast cancer the mitochondrial translocator protein (TSPO) aids pro-survival cellular response by facilitating the formation of mitochondrial contact sites with the nucleus termed Nucleus Associated Mitochondria (NAM). Here, we show that TSPO positively associates with the aggressiveness of tissues and cells isolated from Canine Mammary Tumours (CMTs). TSPO is also readily upregulated in reprogrammed mammary tumour cells following long-term deprivation of oestrogen or exposure to the endocrine chemotherapeutic (ET) agent Tamoxifen.

Background: In randomised controlled trials with efficacy-related primary outcomes, adverse events are collected to monitor potential intervention harms. The analysis of adverse event data is challenging, due to the complex nature of the data and the large number of unprespecified outcomes. This is compounded by a lack of guidance on best analysis approaches, resulting in widespread inadequate practices and the use of overly simplistic methods; leading to sub-optimal exploitation of these rich datasets.

The neuroendocrine control of puberty and reproduction is fascinatingly complex, with up- and down-regulation of key reproductive hormones during fetal, infantile, and later childhood periods that determine the correct function of the hypothalamic-pituitary-gonadal axis and the timing of puberty. Neuronal development is a vital element of these processes, and multiple conditions of disordered puberty and reproduction have their etiology in abnormal neuronal migration or function. Although there are numerous documented cases across multiple conditions wherein patients have both neurodevelopmental disorders and pubertal abnormalities, this has mostly been described ad hoc and the associations are not clearly documented.
