Background: While both motor and cognitive impairment are common after stroke, the focus of (early) treatment has always been on motor deficit.
Aims: The objective of the current study was to explore the link between motor and cognitive performance in stroke patients and to examine whether motor performance is associated with cognitive functioning at three months post stroke.
Methods: In both stroke patients (n = 142) and controls (n = 135), with the groups matched on age, gender and premorbid IQ, motor functioning was evaluated using both objective (Purdue Pegboard Test) and subjective measures (specific items from the Frenchay Activities Index and Barthel Index). Cognition, specifically information processing speed, working memory and cognitive flexibility, was assessed using objective tasks. The data were analyzed using Pearson product-moment correlation coefficients and logistic regression.
Results: Significant correlations between motor and cognitive functioning were found in stroke patients. The objective motor task was stronger than subjective measures in statistically explaining and predicting cognitive deficit, irrespective of stroke severity.
Conclusions: We conclude that motor impairment at three months post-stroke should serve as a 'red flag' for professionals: cognitive impairment is likely and should also be evaluated.

Transoral Robotic Surgery in Chronic Lingual Tonsillitis: An Observational Cohort Study.
Head Neck
January 2025
Department of Otorhinolaryngology - Head and Neck Surgery, Frisius Medical Center, Leeuwarden, Leeuwarden, The Netherlands.
Background: Chronic lingual tonsillitis (CLT) entails persistent inflammation of the lingual tonsils (LT), presenting in recurrent infections, throat discomfort, dyspnea, dysphagia, and LT hypertrophy.
Methods: A retrospective observational study at a nonacademic general hospital described outcomes of CLT patients undergoing base of tongue (BOT) reduction via transoral robotic surgery (TORS). Primary outcomes were changes in patient-reported quality of swallowing and life and were assessed at baseline, 3, 6, and 12 months post-TORS.

Objective: This study aimed to evaluate the medium-term outcome following spinal cord decompression and instrumented fixation of single-level congenital thoracolumbar vertebral malformations, characterized by combined failures of segmentation and formation, causing thoracolumbar myelopathy in three large-breed dogs.
Study Design: This was a retrospective clinical study.
Animals: The animals involved in the study were three large-breed dogs.

Meat quality is a key indicator of meat performance in ruminants, and its mechanism and regulation are also key to ruminant research. Studies have shown that animal meat quality is related to the gut microbiota. In this study, RT-qPCR and 16S omics were employed to assess meat quality and intestinal microbiota.

Background: Inadequate pulmonary blood flow in tetralogy of Fallot (TOF) can lead to the development of major aortopulmonary collateral arteries (MAPCA), which interferes with surgical repair. The present study evaluated the features of MAPCAs among patients with TOF and their treatment approaches. Besides, perioperative parameters and mortality rates of our TOF patients with and without MAPCA were compared.

As Water Sensitive Urban Design (WSUD) is a key strategy in integrated urban water management worldwide, there is a need for robust monitoring of WSUD systems. Being economical and flexible for operation and communication, low-cost sensor systems show great potential to mainstream digital water management. Yet, such systems are insufficiently tested, casting doubt on the reliability of their measurements.
