ECG Blog #458 — Complete Heart Block?

Ken Grauer, MD

I was sent this tracing — and told that providers thought that the rhythm was 3rd-degree ( ie, complete ) AV block. Do YOU agree? Figure-1: The initial ECG in today’s case. NOTE: The tracing in Figure-1 is an 8-lead rhythm strip ( and not a complete 12-lead ECG ). This offers the advantage of providing 8 leads with simultaneously-recorded viewpoints of the same 7 beats that we see in this tracing.

Transcription factor KROX20 marks epithelial stem cell ancestors for hair follicle formation

Journal of Clinical Investigation - Cardiology

Epidermal stem cells control homeostasis and regeneration of skin and hair. In the hair follicle (HF) bulge of mammals, populations of slow-cycling stem cells regenerate the HF during cyclical rounds of anagen (growth), catagen (regression), and telogen (quiescence). Multipotent epidermal cells are also present in the HF above the bulge area, contributing to the formation and maintenance of sebaceous gland and upper and middle portions of the HF.

Finally – the end (of the trial process)

Dr. Malcolm Kendrick

And so, we reach the final end to the court case. You may think it all finished months ago, not so. The final, final act is when we have the reading of the Statement in Open Court (SIOC). This took place Thursday the 5 th of December 2024. Which is five years and nine months after the articles in the Mail on Sunday were published. I could not talk or write about the SIOC before it happened, or the Judge would be most upset and angry.

PCDH15 dual-AAV gene therapy for deafness and blindness in Usher syndrome type 1F models

Journal of Clinical Investigation - Cardiology

Usher syndrome type 1F (USH1F), resulting from mutations in the protocadherin-15 (PCDH15) gene, is characterized by congenital lack of hearing and balance, and progressive blindness in the form of retinitis pigmentosa. In this study, we explore an approach for USH1F gene therapy, exceeding the single AAV packaging limit by employing a dual–adeno-associated virus (dual-AAV) strategy to deliver the full-length PCDH15 coding sequence.

Reactive microglia partially envelop viable neurons in prion diseases

Journal of Clinical Investigation - Cardiology

Microglia are recognized as the main cells in the central nervous system responsible for phagocytosis. The current study demonstrates that in prion disease, microglia effectively phagocytose prions or PrPSc during early preclinical stages. However, a critical shift occurred in microglial activity during the late preclinical stage, transitioning from PrPSc uptake to establishing extensive neuron-microglia body-to-body cell contacts.

Higher ratio of plant protein to animal protein may improve heart health

Science Daily - Heart Disease

Eating a diet with a higher ratio of plant-based protein to animal-based protein may reduce the risk of cardiovascular disease (CVD) and coronary heart disease (CHD), according to a new study. According to the researchers, these risk reductions are likely driven by the replacement of red and processed meats with plant proteins. The researchers also observed that a combination of consuming more plant protein and higher protein intake overall provided the most heart health benefits.

Reduced thymic IL-4 impairs negative T cell selection in nonobese diabetic mice

Journal of Clinical Investigation - Cardiology

Type 1 diabetes (T1D) develops spontaneously despite functional antigen presentation machinery in the thymus and a perceptible central tolerance process. We found that intrathymic enrichment with IL-4 fine tunes signaling through the IL-4/IL-13 heteroreceptor (HR) in early thymic progenitors (ETPs), augments negative selection of self-reactive T cells, sustains a diverse T cell repertoire devoid of clones expressing disease-associated T cell receptor (TCR) genes, and protects the nonobese diabet

Newfound mechanism may explain why some cancer treatments boost risk of heart disease
