Safe use of master-slave robots for endoscopic surgery requires autonomous motions to avert contact with vital organs, blood vessels, and nerves. Here we describe an avoidance control algorithm with delay compensation that takes the dynamic characteristics of the robot into account. To determine the operating parameters, we measured frequency characteristics of each joint of the slave-manipulator. The results suggest this delay compensation program improves avoidance performance.

Background: Dementia represents a significant health challenge, with evidence suggesting that it can be potentially delayed or prevented through non-pharmacological interventions. There are different types of non-pharmacological interventions for Mild Cognitive Impairment (MCI). The Aging Well through Interaction and Scientific Education (AgeWISE) Program is a notable cognitive intervention designed to educate both individuals experiencing normal aging and those with age-related diseases.

Background: The PANORAMA survey aimed to assess current treatment practice for individuals with new diagnoses of relapsing-remitting multiple sclerosis (RRMS) in the United Kingdom and to explore variations in treatment approaches with an emphasis on escalation vs early high-efficacy treatment (HET) and treatment goals.
Methods: Health care professionals (HCPs) from the UK treating patients with RRMS took part in interviews facilitated by a structured questionnaire. Data were analyzed descriptively using quantitative or qualitative methods, as appropriate.

Dysfunctional lymphatic drainage from the central nervous system (CNS) has been linked to neuroinflammatory and neurodegenerative disorders, but our understanding of the lymphatic contribution to CNS fluid autoregulation remains limited. Here, we studied forces that drive the outflow of the cerebrospinal fluid (CSF) into the deep and superficial cervical lymph nodes (dcLN and scLN) and tested how the blockade of lymphatic networks affects CNS fluid homeostasis. Outflow to the dcLN occurred spontaneously in the absence of lymphatic pumping and was coupled to intracranial pressure (ICP), whereas scLN drainage was driven by pumping.

Background: In this study we investigate the selective compensation of paired peripheral nerves in healthy humans, focusing on distinct axonal conduction velocities in different fibre types. Using paired associative stimulation (PAS) with adjustable parameters, we aimed to modulate and compensate for neuronal activity along the median nerve.
Methods: Six healthy volunteers (3 male, 3 female, aged: 22-49) participated in the current study.

Double outlet right ventricle (DORV) is a rare congenital heart defect where both the aorta and pulmonary artery originate from the right ventricle, often accompanied by additional cardiac anomalies to mitigate circulatory imbalance, though such compensations usually fail. We report a 15-month-old infant with recurrent respiratory infections and poor weight gain, referred for computed tomography angiography. Physical examination showed a small, non-syndromic infant with pallor, tachypnea, irritability, and finger clubbing.
