Even though acute kidney injury (AKI) is now treated more frequently with renal replacement therapy (RRT), little is known about how critical care facilities are run in Thailand. This study examined the prevalence of the various RRT modalities that are currently availability and in use to manage patients with AKI in critical care units all around the country. In early 2022, the online survey was sent to nurses who worked in the intensive care unit (ICU) or another critical care unit across the country as part of a cross-sectional survey. The study got a total of 70 answers for the RRT modalities, which are currently available and representative of the capacity of treatment for individual institutions. In terms of modality, intermittent hemodialysis (IHD) and continuous renal replacement therapy (CRRT) are the most commonly available and used treatment for AKI in Thailand’s ICUs. These options are accessible for RRT in the acute setting in this survey, with a rate of as high as 71.43% and 61.43% available across the country, respectively. Additionally, the other options are also available, including either manual or automated peritoneal dialysis (PD), and sustained low efficiency dialysis (SLED).

In Japan, the Clinical Engineer (CE) Law was enacted in 1987, and we have been active in various fields such as equipment maintenance and clinical work. With the aim of reducing the workload of doctors, task shifting was planned and the CE Law was revised in 2021. Even in Thailand, there is a chronic shortage of medical personnel such as doctors and nurses, and from the perspective of patient safety, it is recognized that specialists in the maintenance and operation of medical devices are essential. In the future, it will be necessary to develop personnel with an eye on the task shifting of Biomedical Engineer (BME) in the field where the diversification of medical devices is expected. In 2019 and 2020, we conducted training for BME training on medical devices made in Japan in this project. Establishment of medical safety for patients became a common issue in the future. The 2021 training focused on team medical care participation, monitoring of critically ill patients, and ECMO and CRRT under mechanical ventilation, especially in the ICU. By making CEs’ participation in ICU team medical care the content of the training, we were able to present problems that would arise as medical devices become more complex in the future, and gain the understanding of the Thai side. In Japan, there is a successful example of a task shifting from doctors to CEs. In Thailand, TPQI (Thailand Professional Qualification Institute) has been established as a standard for BME’s professional ability. Through this project, the Thai side will deepen its knowledge of Japanese-made medical devices and use it for training at its own facility, and as medical devices becomes more diverse and complex in the future, it will be possible to understand the experience of participating in team medical care in Japan. We hope that this will lead to improvements in medical safety.
在日本，1987年颁布了《临床工学技士法》，我们一直活跃在设备维护和临床工作等各个领域。为了减少医生的工作量，政府计划转移任务，并于2021年修订《行政长官法》。即使在泰国，医生和护士等医疗人员也长期短缺，从患者安全的角度来看，人们认识到医疗设备的维护和操作专家是必不可少的。在未来，有必要在医疗设备多样化的领域培养着眼于生物医学工程师(BME)任务转移的人才。在2019年和2020年，我们在这个项目中对日本制造的医疗器械进行了BME培训。建立患者的医疗安全成为未来的共同问题。2021年的培训重点是团队医疗参与、危重患者监测以及机械通气下的ECMO和CRRT，特别是在ICU。通过将CEs参与ICU团队医疗护理作为培训的内容，我们能够提出未来医疗设备变得更加复杂时可能出现的问题，并获得泰方的理解。在日本，有一个任务从医生转移到消费电子产品的成功例子。在泰国，TPQI (Thailand Professional Qualification Institute)已被确立为BME专业能力的标准。通过这个项目，泰方将加深对日本制造的医疗器械的了解，并将其用于自己的设施的培训，随着未来医疗器械变得更加多样化和复杂，将有可能了解在日本参加团队医疗的经验。我们希望这将导致医疗安全的改善。

Medical device development is very important and challenging for the healthcare industry in this disruptive era. Innovation in medical devices is demanded as it impacts medical treatments and procedures. The design thinking process has been introduced to create a new product development including medical devices. The five stages of design thinking link the users’ empathy to the proof of prototype. Our work aimed to apply the design thinking process to solve the pain points of surgeons when performing carpal tunnel release. The use of wireless endoscope was our idea to tackle the pain points. We successfully showed that our idea, using the design thinking process, could be developed to a prototype, which could be tested in a cadaver. Moreover, further development can be continued from this prototype in a cycle of test, ideate and prototype.

Amniotic membrane derived from the human placenta is a collagen-based extracellular matrix that contains various growth factors, which offers an excellent source of biological materials for tissue engineering applications. The aim of this study was to investigate different pretreatment conditions combined with gamma irradiation to establish the processing condition for long-term preservation of amniotic membranes as biological wound dressings. Human amniotic membranes (hAMs) were first isolated from donated placentas obtained by caseation, cleaned off blood remnants, and cut into 10 cm $times 10 cm$ sheets. During the pretreatment step, 0.05 - 0.5% (w/v) hypochlorite solution or a combination of penicillin-streptomycin, neomycin, and amphotericin (PNA) solution at 50, 100, and 2.5 $mu$ g/mL, respectively, was first performed to reduce bacterial contamination. After air drying under sterile environment, the amniotic sheets were individually packed and tightly sealed in double-layered polyethylene bags before exposed to gamma irradiation at 25 kGy under cold condition. Plate count methods were performed on as-received hAMs and after pretreatment and gamma irradiation steps to check the bacterial contamination on the samples. Results showed that pretreating the amniotic membranes in 0.5% (w/v) hypochlorite for 2 h or PNA for 18 h could sufficiently reduce the bacterial contamination below 103 colony-forming unit, and gamma irradiation under cold condition could maintain the membranes’ transparency as well as ensure the sterility of samples up to 6 months. Therefore, this combined pretreatment and irradiation steps could be applied to preserve dried hAMs for long-term use as wound dressings.

Carbon nanotubes (CNTs) are hollow cylindrical carbon materials with unique physical, mechanical, and electrical properties. Furthermore, CNTs cut to about 10 nm can spontaneously insert into cell membranes and artificial lipid membranes. Consequently, CNTs are attracting attention for their potential use as protective membranes for sensors, drug delivery systems, nano-dipolar electrodes, and other applications when combined with lipid membranes. CNTs with hydrophobic surfaces can interact with the hydrophobic membrane core to induce membrane deformation. Although changes in membrane morphology are one cause of cytotoxicity, the effects of cut CNTs on membrane morphology are not well understood. In this study, we exposed CNTs to artificial cell membrane vesicles (giant unilamellar vesicles), which are used as a cell model, and evaluated the changes in membrane morphology for each CNT concentration by fluorescence microscopy.

This work evaluates and compares the architectures: Inceptionv4, InceptionResnetV2, and Resnet152, to classify benign and malignant. We evaluate the architectures with a statistical analysis base on the received operational characteristics (ROC), accuracy, precision, recall, and F1 score. We generate the best results with the CNN InceptionResnetV2 trained with two classes on a balanced mammogram database. The results for benign cases have a ROC of 0.93, a precision of 0.8319, a recall of 0.9216, and an F1-score of 0.8744. The results for malignant cases have a ROC of 0.91, a precision of 0.9121, a recall of 0.8137, and an F1-score of 0.8601.

According to Beck’s cognitive model of depression, depression has an effect on schema, which leads to biased cognition. Depressive states and depression symptoms are considered to occur on a continuum, with only qualitative differences between them. However, it remains unclear whether there are significant differences in information processing among healthy individuals. In this study, we investigated the event-related potentials (ERPs) and event-related spectrum perturbation (ERSP) of healthy individuals with various depressive states during emotional stimulation. We found that participants in a high depressive state had a lower P300 amplitude. Moreover, we identified significant differences in fast and slow neural responses in the frontal and parietal lobes, which might indicate a cognitive bias in healthy individuals.

Drug delivery systems (DDSs) that selectively and efficiently deliver drugs to target sites can be made more effective by using ultrasound. However, ultrasound-based DDSs have the problem that the drug carriers often react to other stimuli besides ultrasound. Therefore, we propose liposomes encapsulating metal nanoparticles (e.g., tungsten particles) as carriers that respond only to ultrasound. In this study, liposomes and metal nanoparticle-encapsulated liposomes were prepared by an emulsion-based method, and the changes in brightness due to calcein release upon ultrasound irradiation were observed under a microscope. The results confirmed that the incorporation of & metal nanoparticles into the liposomes enhanced their response to ultrasound.

Due to the global epidemic situation of the Coronavirus Disease 2019 (Covid-19), in addition to serving patients with suspected symptoms and sickness from COVID-19, the hospital also provides services to patients outside requiring a lot of treatment causing a large number of queues in patients. It takes a long time to wait to see the doctor. The researcher therefore developed a teleconsultation platform. Hence, that patients can talk or seek advice from a doctor without the need to go to the hospital, allow patients to schedule appointments to see a doctor. Also, the patient can talk to the doctor via video calling developed in the system. Moreover, doctors can dispense medicines to patients by mail. To increase the efficiency of the system more and to support a wide range of applications, any devices, real-time data updates, appointment notification via chatbot using Cloud Firestore and Realtime Databases, a NoSQL database, and study the performance gained. The results obtained from the test were satisfactory, with an average tracing server response of 107 ms + 0.14%, and an average handling latency in Thailand at 108 ms.
由于2019冠状病毒病(Covid-19)的全球流行形势，医院除了服务有Covid-19疑似症状和疾病的患者外，还为需要大量治疗的患者提供服务，导致患者大量排队。看医生要等很长时间。因此，研究人员开发了一个远程咨询平台。因此，患者可以与医生交谈或寻求建议，而不需要去医院，允许患者预约看医生。此外，患者可以通过系统中开发的视频通话与医生交谈。此外，医生可以通过邮件给病人配药。为了提高系统的效率，并支持广泛的应用程序，任何设备，实时数据更新，约会通知通过聊天机器人使用云Firestore和Realtime数据库，NoSQL数据库，并研究所获得的性能。测试获得的结果令人满意，跟踪服务器的平均响应为107 ms + 0.14%，泰国的平均处理延迟为108 ms。

Hence, that patients can talk or seek advice from a doctor without the need to go to the hospital, allow patients to schedule appointments to see a doctor. Also, the patient can talk to the doctor via video calling developed in the system. Moreover, doctors can dispense medicines to patients by mail. To increase the efficiency of the system more and to support a wide range of applications, any devices, real-time data updates, appointment notification via chatbot using Cloud Firestore and Realtime Databases, a NoSQL database, and study the performance gained.

Loss of hand dexterity is a major challenge faced by post-stroke patients who strive to resume their ordinary daily lives. Effective hand function rehabilitation treatment for such population is therefore necessary. A soft robotic glove system operated through SSVEP-based BCI has been reported to be an effective tool for post-stroke hand motor function recovery. This study further evaluated the application of visual stimulation in the alpha band for SSVEP-assisted rehabilitation. We compared the treatment outcome with stimulations within the alpha band to that outside the band. A total of 20 post-stroke patients with severe upper limb dysfunction were randomly assigned to alpha band group and non-alpha band group. The experiment result was assessed with Fugl-Meyer upper limb Motor Assessment (FMAUE) and alpha EEG oscillation analysis. The alpha band group showed slightly but notably higher FMA-UE scores $(mathrm{P}lt 0.05)$, and significantly increased alpha wave EEG oscillations $(mathrm{P}lt 0.05)$. The result demonstrated the usefulness of alpha band SSVEP for post stroke hand function rehabilitation.
