Inter-individual coordination in walking chimpanzees.

Humans, like many other animals, live in groups and coordinate actions with others in social settings. Such interpersonal coordination may emerge unconsciously and when the goal is not the coordination of movements, as when falling into the same rhythm when walking together. Although one of our closest living relatives, the chimpanzee (Pan troglodytes), shows the ability to succeed in complex joint action tasks where coordination is the goal, little is known about simpler forms of joint action.

An engaged approach to exploring issues around poverty and mental health: A reflective evaluation of the research process from researchers and community partners involved in the DeStress study.

Background: Involving patients, service users, carers and members of the public in research has been part of health policy and practice in the UK for the last 15 years. However, low-income communities tend to remain marginalized from the co-design and delivery of mental health research, perpetuating the potential for health inequalities. Greater understanding is therefore needed on how to meaningfully engage low-income communities in mental health research.

The J-Curve for Navigating the Nasolacrimal Outflow Tract.

Purpose: To describe the technique of J-shaped manipulation of the metallic stent for instrument-free intubation of the nasolacrimal outflow tract after dacryocystorhinostomy.

Methods: The internal diameter of the J-shaped curve placed in the intubation stents was measured and the technique of intubation of the nasolacrimal outflow tract and out the external naris is described. In addition, the anatomic relationships of the nasolacrimal system are illustrated and videographed in relation to the described procedure.

Relapsing acute lymphoblastic leukemia presenting with a rapidly enlarging and vision-threatening orbital mass.

This case report describes a patient with known acute lymphoblastic leukemia (ALL) presenting with a rapidly enlarging and vision-threatening orbital mass. Orbital disease is rare in patients with ALL, and to our knowledge only six cases have been previously described, five of which are in children. We describe a 36-year-old Caucasian female with known acute lymphoblastic leukemia who developed markedly decreased visual acuity, proptosis, and elevated intraocular pressure over the course of 12 h.
