Electrochemical analysis of sweat using soft bioelectronics on human skin provides a new route for noninvasive glucose monitoring without painful blood collection. However, sweat-based glucose sensing still faces many challenges, such as difficulty in sweat collection, activity variation of glucose oxidase due to lactic acid secretion and ambient temperature changes, and delamination of the enzyme when exposed to mechanical friction and skin deformation. Precise point-of-care therapy in response to the measured glucose levels is still very challenging...

In addition to locally controlling the tumor, hypofractionated radiotherapy (RT) particularly aims to activate immune cells in the RT-modified microenvironment. Therefore, we examined whether hypofractionated RT can activate dendritic cells (DCs), induce immune cell infiltration in tumors, and how the chronology of immune cell migration into tumors occurs to gain knowledge for future definition of radiation breaks and inclusion of immunotherapy. Colorectal cancer treatments offer only limited survival benefit, and immunobiological principles for additional therapies need to be explored with preclinical models...

It is difficult to meet the requirements of clinical diagnosis through a single imaging technique. Similarly, satisfactory therapy efficacy is also hard to achieve by a single therapeutic modality. It is therefore highly desirable and interesting to simultaneously achieve multimodal imaging and therapies in one single structure. In this study, we developed a core-shell-satellite NaGdF4:Yb,Er,Mn,Co@mSiO2-CuS structure using up-conversion luminescent (UCL) NaGdF4:Yb,Er,Mn,Co as the core, mesoporous silica as the layer, and the photoactive CuS nanoparticles as the satellites...

Quantitative sensory tests (QST) have been increasingly used to investigate alterations in somatosensory function in a wide range of painful conditions. The interpretation of these findings is based on the assumption that the measures are stable and reproducible. To date, reliability of QST has been investigated for short test-retest intervals. The aim of this study was to investigate the long-term reliability of a multimodal QST assessment in healthy people, with testing conducted on three occasions over 4-months...

BACKGROUND: Central serous chorioretinopathy (CSC), which has the characteristics of a serous retinal detachment (SRD) in the macular area, affects mostly men in the 30- to 50-yr age range. Some patients have persistent SRD, which may cause retinal thinning and photoreceptor impairment. CSC symptoms are gradual vision loss and/or metamorphopsia. Some commercial airline pilots are concerned about CSC symptoms, which can disqualify them from flying for months and can also reoccur. Thus, careful monitoring and treatment of CSC are critical for pilots, especially those with chronic or recurrent CSC...

REVIEW
Michael A Quail, Albert J Sinusas
Imaging in heart failure (HF) provides data for diagnosis, prognosis and disease monitoring. Both MRI and nuclear imaging techniques have been successfully used for this purpose in HF. Positron Emission Tomography-Cardiac Magnetic Resonance (PET-CMR) is an example of a new multimodality diagnostic imaging technique with potential applications in HF. The threshold for adopting a new diagnostic tool to clinical practice must necessarily be high, lest they exacerbate costs without improving care. New modalities must demonstrate clinical superiority, or at least equivalence, combined with another important advantage, such as lower cost or improved patient safety...

Recently high-resolution, noninvasive, multimodality in-vivo molecular imaging with PET, SPECT, CT and MRI, employing fusion algorithms has revolutionized personalized medicine. However, specific radiopharmaceuticals (RPs) for the accurate diagnosis and effective treatment of progressive neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, drug addiction, and other cognitive impairments still remain in developmental phase. Currently, multimodality fusion neuroimaging is utilized for the determination of: pharmacokinetics and pre-clinical development of radiopharmaceuticals (RPs); in-vivo monitoring of stem cell transplantation therapy; nicotinic acetylcholine receptors (nAChRs) investigations; and regional cerebral blood flow and glucose metabolism in cognitively-impaired subjects employing noninvasive microPET and nano-SPECT imaging...

BACKGROUND: Multimodal analgesia inclusive of periarticular injection with a local anesthetic agent has been rapidly assimilated, with demonstrated safety and efficacy, into the care of patients undergoing elective lower-extremity arthroplasty. The present study was performed to evaluate the efficacy and safety of a surgical-site, multimodal drug injection for postoperative pain control following operative management of femoral fractures. METHODS: There were 102 patients undergoing operative intervention (plate fixation, intramedullary device, or arthroplasty) for a broad range of femoral fracture patterns who were prospectively randomized either to receive an intraoperative, surgical-site injection into the superficial and deep tissues containing ropivacaine, epinephrine, and morphine or to receive no injection...

Multimodal coregistration uses multiple image datasets coregistered to an anatomical reference (i.e. MRI), allowing multiple studies to be viewed together. Commonly used in intractable epilepsy evaluation and generally accepted to improve localization of the epileptogenic zone, data showing that coregistration improves outcome is lacking. We compared seizure freedom following epilepsy surgery in paediatric patients, evaluated before and after the use of coregistration protocols at our centre, to determine whether this correlated with a change in outcome...

BACKGROUND: Persistent hyperlactatemia is particularly difficult to interpret in septic shock. Besides hypoperfusion, adrenergic-driven lactate production and impaired lactate clearance are important contributors. However, clinical recognition of different sources of hyperlactatemia is unfortunately not a common practice and patients are treated with the same strategy despite the risk of over-resuscitation in some. Indeed, pursuing additional resuscitation in non-hypoperfusion-related cases might lead to the toxicity of fluid overload and vasoactive drugs...

In this paper, we present a flexible temperature sensor with ultra-small polysilicon thermistors for brain temperature monitoring. In vitro sensitivity, resolution, thermal hysteresis and long term stability tests were performed. Temperature coefficient of resistance (TCR) of -0.0031/ °C and resolution of 0.1 °C were obtained for the sensor. Thermal hysteresis for temperature range of 30~45 °C was less than 0.1 °C. With silicon nitride as the passivation layer, the temperature sensor showed a drift within 0...

An automated patient-specific system to classify the level of sedation in ICU patients using heart rate variability signal is presented in this paper. ECG from 70 mechanically ventilated adult patients with administered sedatives in an ICU setting were used to develop a support vector machine based system for sedation depth monitoring using several heart rate variability measures. A leave-one-subject-out cross validation was used for classifier training and performance evaluations. The proposed patient-specific system provided a sensitivity, specificity and an AUC of 64%, 84...

Multimodal brain monitoring is an important approach to gain insight into brain function, modulation, and pathology. We have developed a unique micromachined neural probe capable of real-time continuous monitoring of multiple physiological, biochemical and electrophysiological variables. However, to date, it has only been used in anesthetized animals due to a lack of an appropriate interface for awake animals. We have developed a versatile headstage for recording the small neural signal and bridging the sensors to the remote sensing units for multimodal brain monitoring in awake rats...
