A new scientific statement identifies the risks and benefits of novel interventional devices compared to anticoagulation alone in the treatment of patients with pulmonary embolism. Authors conclude there is little data — particularly, as it pertains to the treatment of patients with 'intermediate-risk PE' — that suggests these interventional approaches are more safe and effective than the use of anticoagulation alone.

Weak spot in pathogenic bacteria

Antibiotics are still the most important weapon for combatting bacterial infections. But medical science is running out of ''ammunition'' because of more and more frequently occurring resistances. Research teams have now elucidated the structure of the proteolytic complex ClpX-ClpP. This is a key to development of innovative antibiotics which target the degradation process of defective proteins in bacteria.

New defensive mechanism against bacterial wound infections

Wound inflammation which results in impaired wound healing can have serious consequences for patients. Researchers have discovered a new defensive mechanism which enables our skin to actively kill bacteria. Central to this mechanism is a cellular messenger molecule known as 'interleukin 6', whose mode of action may be used in the future to prevent wound infections.
