There are already many ion detection methods available, and their development in long-term application practice has become very mature, which can achieve high-precision monitoring of different ion types and ion concentrations. However, in order to meet the requirements of modern smart healthcare, portable ion continuous monitoring methods with good portability, low operational difficulty, and high detection efficiency urgently need to be developed. However, existing detection methods are far from meeting the requirements of real-time and long-term health monitoring due to factors such as detection principles. In recent years, breakthroughs have been made in miniaturized and portable ion continuous monitoring technology, among which high-sensitivity and high-specificity miniature ion sensing components and miniaturized low-power driving measurement circuits have become the main research contents of this technology. This article starts with high-performance ion sensors in the front-end and high-level integrated driving measurement circuits in the back-end, summarizes the current development of miniaturized and portable ion continuous monitoring technology, reviews its applications, and looks forward to the possible development directions of portable ion monitoring technology in the future.

Objective To compare the environmental microbiological and physical monitoring parameters between the temporary extended medical area and the normal area during the flexible allocation of ward, summarize the rule and find the potential risk points of infection control. Methods From April 10th to 23rd, 2023, prospective environmental microbial monitoring and physical parameter monitoring were carried out in a ward of Zhongnan Hospital of Wuhan University, and the monitoring results under different scenarios were compared and analyzed. Results In general, the carbon dioxide (CO2) concentration, particulate matter 2.5 (PM2.5) concentration, temperature, and relative humidity in the temporary medical area were better than those in the inpatient rooms (P<0.05), but there was no statistically significant difference in the amount of microorganisms detected on the surface of environmental objects or the hands of medical staff (P>0.05). After the start of the temporary medical area, the amount of microorganisms detected on the surface of environmental objects, CO2 concentration, and temperature in the inpatient rooms were higher than those in the temporary medical area (P<0.05), the PM2.5 concentration in the inpatient rooms was lower than that in the temporary medical area (P<0.05), and there was no statistically significant difference in the amount of microorganisms detected on the hands of medical staff or relative humidity between the two areas (P>0.05). Compared with those in the same area when the temporary medical area was not started, in the inpatient rooms after the start, the amount of microorganisms detected in the air, CO2 concentration, temperature, and relative humidity were lower (P<0.05), the amount of microorganisms detected on the surface of environmental objects and PM2.5 concentration were higher (P<0.05), and there was no statistically significant difference in the amount of microorganisms detected on the hands of medical staff between the two periods (P>0.05); in the temporary medical area after the start, the PM2.5 concentration was higher (P<0.05), the CO2 concentration and temperature were lower (P<0.05), and the differences in the relative humidity and amounts of microorganisms detected on the surface of environmental objects and the hands of medical staff between the two periods were not statistically significant (P>0.05). Regardless of whether the temporary medical area was activated or not, Filamentous fungi had the highest detection rates in air samples, and Staphylococcus epidermidis had the highest detection rates in both environmental surface samples and medical staff hand samples. Conclusion A series of environmental risks such as environmental microbial load and poor ventilation caused by temporary medical areas should be paid attention to.

This paper explored the feasibility of using ultrasonic Nakagami statistic parameter imaging to evaluate the thermal lesion induced by microwave ablation (MWA) in porcine models. In this paper, thermal lesions were induced in livers and kidneys in 5 swines using a clinical MWA system. During this treatment progress, ultrasonic radiofrequency (RF) data were collected. The dynamic changes of Nakagami parameter in the thermal lesion were calculated, and the ultrasonic B-mode images and Nakagami images were reconstructed simultaneously. The contrast-to-noise ratio (CNR) between the thermal lesion and the surrounding normal tissue was calculated over the MWA procedure. After MWA, a bright hyperechoic region appeared in the ultrasonic Nakagami image as an indicator of the thermal lesion and this bright spot enlarged with lesion development during MWA exposure. The mean value of Nakagami parameter in the liver and kidney increased from 0.78 and 0.79 before treatment to 0.91 and 0.92 after treatment, respectively. During MWA exposure, the mean values of CNR calculated from the Nakagami parameter increased from 0.49 to 1.13 in the porcine liver and increased from 0.51 to 0.85 in the kidney, which were both higher than those calculated from the B-mode images. This in vivo study on porcine models suggested that the ultrasonic Nakagami imaging may provide an alternative modality for monitoring MWA treatment.

PurposeTo analyze the effect of medication withdraw (MW) on long-term electroencephalogram (EEG) monitoring in children who need preoperative assessment for refractory epilepsy.MethodsRetrospective analysis was performed on the data of preoperative long-term EEG monitoring of children with refractory epilepsy who needed preoperative evaluation in the Pediatric Epilepsy Center of Peking University First Hospital from August 2018 to December 2019. Monitoring duration: at least three habitual seizures were detected, or the monitoring duration were as long as 10 days. MW protocol was according to the established plan.ResultsA total of 576 children (median age 4.4 years) required presurgical ictal EEGs, and 75 (75/576, 13.0%) needed MW for ictal EEGs. Among the 75 cases, 38 were male and 37 were female. The age range was from 15 months to 17 years (median age: 7.0 years). EEG and clinical data of with 65 children who strictly obey the MW protocol were analyzed. The total monitoring duration range was from 44.1 h (about 2 days) to 241.8 h (about 10 days)(median: 118.9 h (about 5 days)). Interictal EEG features before MW were including focal interictal epileptiform discharge (IED) in 39 cases (39/65, 60%), focal and generalized IED in 2 cases (2/65, 3.1%), multifocal IED in 20 cases (20/65, 30.7%), multifocal and generalized IED in 2 cases (2/65, 3.1%), and no IED in 2 cases (2/65, 3.1%). After MW, 18 cases (18/65, 27.7%) had no change in IED and the other 47 cases had changes of IED after MW. And IEDs in 46 cases (46/65, 70.8%) were aggravated, and IED was decreased in 1 case. The pattern of aggravated IED was original IED increasement, in 41 cases (41/46, 89.1%), and 5 cases (5 /46, 10.9%) had generalized IED which was not detected before MW. Of the 46 patients with IED exacerbations, 87.3% appeared within 3 days after MW. Habitual seizures were detected in 56 cases (86.2%, 56/65) after MW, and within 3 days of MW in 80.4% cases. Eight patients (14.3%) had secondary bilateral-tonic seizure (BTCS), of which only 1 patient had no BTCS in his habitual seizures. In 56 cases, 94.6% (53/56) had seizures after MW of two kinds of AEDs.Conclusions① In this group, thirteen percent children with intractable epilepsy needed MW to obtain ictal EEG; ② Most of them (86.2%) could obtain ictal EEG by MW. The IED and ictal EEG after MW were still helpful for localization of epileptogenic zone; ③ Most of the patients can obtain ictal EEG within 3 days after MW or after MW of two kinds of AEDs;4. The new secondary generalization was extremely rare.
