Vascular Access and Management of Complications.

Vascular access requires a deliberate and thoughtful approach. Optimal femoral access involves understanding anatomic, fluoroscopic, and ultrasound principles. Combining all 3 approaches optimizes femoral access and minimizes complications, with ultrasound guidance showing the most promising results for procedural success and safety.

Can we trust published evidence on point-of-care tests for cholesterol? A rapid review.

Objectives: There is a need to better inform clinicians and decision-makers in primary or community care settings on selecting the appropriate point-of-care tests (POCTs) for screening purposes (as a part of the NHS Health Check Programme). Here we provide an overview of the published analytic validity and diagnostic accuracy studies on POCTs for measuring blood lipids that are available on the UK market to determine whether they meet the accuracy specifications based on the 1995 US National Cholesterol Education Program (NCEP) recommendations.

Design: Rapid review of analytical validity and diagnostic accuracy studies.

Hardware-efficient quantum error correction via concatenated bosonic qubits.

To solve problems of practical importance, quantum computers probably need to incorporate quantum error correction, in which a logical qubit is redundantly encoded in many noisy physical qubits. The large physical-qubit overhead associated with error correction motivates the search for more hardware-efficient approaches. Here, using a superconducting quantum circuit, we realize a logical qubit memory formed from the concatenation of encoded bosonic cat qubits with an outer repetition code of distance d = 5 (ref.

Dynamics of infant white matter maturation from birth to 6 months.

The first months after a baby's birth encompass the most rapid period of postnatal change in the human lifespan, but longitudinal trajectories of white matter maturation in this period remain uncharted. Using densely sampled diffusion tensor images collected longitudinally at a mean rate of 1 scan per 1.55 days, we measured non-linear growth and growth rate trajectories of major white matter tracts from birth to 6 months.
