Summary: This article highlights the importance of methodological transparency and consensus in assessing central aortic blood pressure (aoBP) for both clinical and physiological research. Factors such as recording method, mathematical model, and calibration of pulse waveforms should be taken into consideration when analyzing and comparing aoBP data from different sources. The article also addresses the lack of consensus on non-invasive measurement of aoBP and the potential role of aoBP-guided therapy in everyday practice.

Summary: In this non-invasive study, the estimation of central systolic blood pressure (cSBP) using the DCBP formula was compared with the estimation using radial tonometry. The results showed a linear relationship between cSBP estimated by DCBP and cSBP estimated by radial tonometry, and the DCBP method exhibited good sensitivity and specificity in discriminating high blood pressure threshold.

Summary: This study compared the correlation of oscillometric blood pressure measurements with intra-arterial measurements in obese and nonobese children, revealing lower correlation between oscillometric and intra-arterial measurements during hypertension or hypotension. Healthcare providers should be mindful of the limitations of oscillometric measurements.

Summary: The study found that in patients with shock, both oscillometric blood pressure monitoring devices were successful in completing hemodynamic assessments, but there were significant differences between invasive and non-invasive techniques. There were discrepancies in pulse wave velocity measurements between the two devices. Non-invasive peripheral blood pressure measurement may not always be successful in certain circumstances.

Summary: This study investigated the factors influencing the accuracy of noninvasive central blood pressure (cSBP) measurement. The results showed that noninvasive cSBP measurements are comparable to invasive measurements, although they may slightly underestimate true cSBP. The type of BP measurement device used may affect the accuracy of measurement, while the type of calibration method implemented does not have a significant influence.

Summary: This study evaluated the accuracy of the Antares algorithm in estimating central blood pressure in patients with type 2 diabetes and compared it with invasively measured central blood pressure. The results showed that the Antares algorithm can accurately estimate central blood pressure and can be applied to patients with type 2 diabetes.

Summary: This study demonstrates the advantages of non-invasive central blood pressure monitoring and validates the accuracy of different devices through comparison with invasive measurements. It also provides a novel method of validation using recognized gold standard transducers and highlights the potential for easily measuring pulse wave velocity during coronary angiography.

Summary: The study developed an Electrical Impedance Function (EIF) to estimate central aortic blood pressure waveforms from radial waveforms non-invasively, showing comparable or better performance to existing methods and better signal shape retention at the dicrotic notch, making it potentially viable for non-invasive central blood pressure monitoring due to its low computation time and high accuracy.

Summary: This study investigated the acute associations between personal levels of temperature variability and cardiorespiratory biomarkers. The results showed that temperature variability was associated with blood pressure, inflammation biomarkers, and stress response biomarkers. These associations were more prominent in females and subjects with abnormal body mass index.

Summary: This study assessed the accuracy of oscillometric blood pressure measurement at the ankle in children undergoing noncardiac surgery, using invasive blood pressure as the reference standard. The results showed that ankle blood pressure was not interchangeable with invasive readings, with ankle mean arterial pressure (MAP) having the least bias compared to systolic and diastolic blood pressure (SBP, DBP). An ankle MAP > 70 mmHg can exclude hypotension with a negative predictive value of 100%.

Summary: The study found that the oscillometric device used to measure NIBP did not meet the validation criteria set by ACVIM, although it showed good agreement for DAP and MAP measurements, it was not accurate for SAP measurements. Considering the small size of the animals and the difficulty in performing percutaneous arterial catheterization, this device might be a useful tool to assess MAP and DAP during anesthetic procedures in adult guinea pigs.

Summary: Standard compression in freehand 3D ultrasound induces a bias in volume calculations, but minimal compression and gel pad methods have similar results. With a trained examiner and precautions, the bias can be minimized and become acceptable in clinical applications.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: The existing methods for predicting hip and lumbosacral joint centres in Japanese adults are biased and differ between sexes. We propose new regression equations that consider soft-tissue thickness, sex differences, and a height-directional measure, and validate them using leave-one-out cross-validation.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.

Summary: This study investigates the biomechanical effects of robot-assisted body weight unloading (BWU) on gait patterns in healthy young adults. The results show that dynamic robot-assisted BWU enables reduced kinetic requirements without distorting biomechanically normal gait patterns during overground walking.
