Targeting proteoglycan receptor PTPσ restores sensory function after spinal cord dorsal root injury by activation of Erks/CREB signaling pathway.

Dorsal root injury commonly results in irreversible loss of sensory functions because of the limited intrinsic regenerative capacity of adult sensory axons and the growth-inhibitory environment at the dorsal root entry zone (DREZ) between the dorsal root and the spinal cord. Chondroitin sulfate proteoglycans (CSPGs) are the dominant suppressors of axonal regeneration, acting via neuronal receptors including protein tyrosine phosphatase-σ (PTPσ). ISP (Intracellular Sigma Peptide) is a small peptide mimetic of the PTPσ wedge region that has been developed to target PTPσ and relieve CSPG inhibition.

New Hong Kong statute protects factual statements in medical apologies from use in litigation.

Providing an apology which contains a factual explanation following a medical adverse incident may facilitate an amicable settlement and improve patient experience. Numerous apology laws exist with the aim of encouraging an apology but the lack of explicit and specific protection for factual admissions included in "full" apologies can give rise to legal disputes and deter their use. The new Hong Kong Apology Ordinance expressly prohibits the admission of a statement of fact in an apology as evidence of fault in a wide range of applicable proceedings and thus provides the clearest and most comprehensive apology protection to date.

Malpractice litigation in acute stroke care - where are we now?

Acute stroke care has undergone momentous changes in recent years with the introduction of intravenous thrombolysis, mechanical thrombectomy and integrated stroke services. While these are welcome developments, they also carry unique medico-legal challenges. In 2015, a patient from Greater Manchester was awarded over £1 million in compensation after ambulance paramedics failed to admit her to a specialist unit.
