Department of Neurosurgery, Kohka Public Hospital, Kohka, JPN.
Central venous catheters (CVCs) are commonly used for multiple clinical purposes. The internal jugular vein (IJV) is preferred among the most frequently used insertion sites due to its higher success rates and lower complication risks. Although CVC placement is generally considered a safe procedure, several complications have been reported.

Implantable hemodynamic devices like the CardioMEMS HF System are commonly used to manage fluid status in patients with heart failure (HF) by measuring pulmonary pressures. Although CardioMEMS has been shown to reduce HF hospitalizations, rare complications (eg, device endothelialization) can occur and warrant clinical attention. A 67-year-old woman with HF with preserved ejection fraction and group 2 pulmonary hypertension experienced recurrent HF exacerbations.

Alzheimers Dement (Amst)
January 2025
Introduction: Increasing evidence links amyloid beta (Aβ) aggregation with inflammation. This pilot study investigated the use of an immunoassay panel to map biomarker changes in patients with Alzheimer's disease (AD). Furthermore, we evaluated the stability of protein quantification after multiple freeze-thaw cycles (FTCs).

BMC Oral Health
January 2025
The First Affiliated Hospital of Chongqing Medical University, No. 1 Youyi Road, Yuzhong District, Chongqing, 400016, P.R. China.
Objective: To investigate the effects of modified twin-block appliances (MTBA) on obstructive sleep apnea (OSA) and mandibular retrognathia and the changes in the upper airway, hyoid bone position, and hypoxia-related inflammatory marker levels in children with OSA.
Methods: This study included children with OSA and mandibular retrognathia and those with class I without mandibular retrognathia (n = 35 each). The experimental group comprised children with OSA and mandibular retrognathia managed using MTBA.
Ramp Protocol for Non-linear Cerebrovascular Reactivity with Transcranial Doppler Ultrasound.
J Neurosci Methods
January 2025
IBME, Department of Engineering Science, University of Oxford, Oxford UK.
Background: Cerebrovascular reactivity (CVR) reflects the ability of cerebral blood vessels to adjust their diameter in response to vasoactive stimuli, which is crucial for maintaining brain health. Traditional CVR assessments commonly use a two-point measurement, assuming a linear relationship between cerebral blood flow (CBF) and arterial CO. However, this approach fails to capture non-linear characteristics, particularly the plateaus at extreme CO levels.
