Mostly Microbes and Infection

Chlamydia est un micro-organisme responsable d'une maladie sexuellement transmissible ; cette bactérie peut aussi causer cécité, maladies cardiaques et pulmonaires. Améliorer son dépistage pour en limiter la propagation et traiter à un stade précoce sont deux enjeux essentiels.

  The climate crisis is caused by rising atmospheric levels of greenhouse gases, in particular carbon dioxide, methane and nitric oxide. While major industries and agriculture are the largest contributors to global climate change, ostensibly benign professions such as dentistry also play a role. The articles in this special collection of the   CDA Journal   explore the impact of climate change on dentistry and offer insights into how dental professionals can reduce their carbon footprint while maintaining safe high-quality care. Like other healthcare delivery settings, dental practices rely on a range of materials, resources and methods that contribute to greenhouse gas emissions. In the United States, emissions from the healthcare sector account for 8.5% of national emissions and continue to increase. Citation 1 , Citation 2  Dentistry, like other healthcare professions, is thus faced with the challenge of balancing patient care and safety with increasing environmen...

  This commentary describes the changes taking place in dentistry and speculates on improvements that could happen soon. Advances in health care will have an impact on the integration and delivery of oral care; conversely, there is growing acceptance that oral health impacts systemic health. Technological innovations are changing the face of medical care and are quickly becoming integrated into dentistry. Advances in novel antimicrobials, genomics, robotics and artificial intelligence are transforming our ability to diagnose and manage disease.

The circadian rhythm controls a wide range of functions in the human body and is required for optimal health. Disruption of the circadian rhythm can produce inflammation and initiate or aggravate chronic diseases. The modern lifestyle involves long indoor hours under artificial lighting conditions as well as eating, working, and sleeping at irregular times, which can disrupt the circadian rhythm and lead to poor health outcomes. Seasonal solar variations, the sunspot cycle and anthropogenic electromagnetic fields can also influence biological rhythms. The possible mechanisms underlying these effects are discussed, which include resonance, radical-pair formation in retina cryptochromes, ion cyclotron resonance, and interference, ultimately leading to variations in melatonin and cortisol. Intracellular water, which represents a coherent, ordered phase that is sensitive to infrared light and electromagnetic fields, may also respond to solar variations and man-made electromagnetic fields. ...
