Sentience in cephalopod molluscs: an updated assessment

Biological Reviews, Volume 101, Issue 3, Page 1311-1333, June 2026.
ABSTRACT This article evaluates the evidence for sentience – the capacity to have feelings – in cephalopod molluscs: octopus, cuttlefish, squid, and nautilus. Our framework includes eight criteria, covering both whether the animal's nervous system could support sentience and whether their behaviour indicates sentience.

Dual chamber pacemaker implantation in persistent left superior vena cava – A case report

IHJ Cardiovascular Case Reports, 2018
Persistent left superior vena cava (PLSVC) associated with an absent right superior vena cava (RSVC) is a very rare congenital abnormality most commonly discovered incidentally. Pacemaker implantation in these cases may be challenging.

Acute Pericardial Effusion After Vein of Marshall Ethanol Infusion for Persistent Atrial Fibrillation

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
This study reports a 25.2% incidence of acute pericardial effusion following vein of Marshall ethanol infusion for persistent atrial fibrillation. The extent of the resulting low‐voltage area was identified as an independent predictor of pericardial effusion, reflecting the magnitude of chemical injury.

Superior vena caval syndrome caused by the tumor of the left hilum in a patient with unilateral persistent left superior vena cava diagnosed with multislice spiral computed tomography : a case report [PDF]

, 2007
Background: Unilateral persistent left superior vena cava (PLSVC) is an infrequent finding with incidence of 18-20% among the individuals with PLSVC. The persistence of the left-sided superior vena cava is an effect of disturbances in development of the ...

Insertion of a non-tunneled catheter for hemodyalisis in the persistent left superior vein cava: incidental finding

Nefrología Latinoamericana
For patients receiving hemodialysis, central venous catheters are essential. There are anatomical variations, present in a small percentage of the population.

Wavefront‐Like LAM Method: A Case Report of Residual Potential Identification Using Local Voltage Derived From Late Annotation Mapping

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
The Wavefront‐like LAM method preserves wavefront‐based timing consistency while enabling quantitative local voltage evaluation. This method improves differentiation between low‐voltage and no‐voltage regions and suggests that residual potentials appearing isolated on conventional voltage mapping can be identified.

Usefulness of a lead delivery system consisting of a fixed-shaped sheath and a lumenless bipolar lead in a patient with absent right and persistent left superior vena cava: A case report

Indian Pacing and Electrophysiology Journal, 2018
We report the case of an 84-year-old female with symptomatic bradycardia due to a complete atrioventricular block, who carried absent right and persistent left superior vena cava (SVC).

Efficacy and Safety of Catheter Ablation in Very Elderly Patients With Atrial Fibrillation: Short‐ To Mid‐Term Outcomes From a Multicenter Study

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
Patients aged ≥ 80 years with atrial fibrillation underwent catheter ablation. At 2 years, the recurrence‐free survival rate was 85.8% in paroxysmal AF and 63.6% in persistent AF (p = 0.024), and periprocedural complications occurred in 12.0%, including severe complications in 3.3%.

Feasibility and Safety of High‐Power Settings for Electrical Isolation of the Superior Vena Cava Using a Catheter Capable of Local Impedance and Contact Force Monitoring

Journal of Arrhythmia, Volume 42, Issue 3, June 2026.
High‐power superior vena cava isolation using a contact force– and local impedance–sensing catheter achieved safe and consistent first‐pass isolation. Local impedance decreased more rapidly than generator impedance, accurately reflecting effective lesion formation and enabling reliable real‐time assessment in thin SVC myocardium.
