Deployment of RFID, GPS and IOT technology for medical specimen logistic system
Authors:   , Chit Mya 
Published: September 2023

This paper aims to implement a specimen logistic system using RFID technology combined with modern IoT technology in Chulalongkorn hospital. The specimen is a sample collected from the human body. Samples can be urine, saliva, sputum, feces, semen, and other bodily fluids and tissues. Samples are usually collected from the patient and stored in a test tube. Then test tubes are delivered to the corresponding laboratory for examination. Normally, barcodes are tagged over the test tubes for the purpose of recording patient information. In this work, RFID is deployed on the test tube instead for patient data logging. This solution overcomes the limitations imposed by using the barcode labels. RFID tag, which is attached on the test tube, has a memory to store patient information which can be written by using an RFID reader. While test tubes being in transit from one department to another, they are kept in a specimen transport cooler box to maintain their quality in proper temperature and humidity. In addition, IoT sensor and GPS system are employed inside the cooler box to provide the temperature and humidity values, as well as the location tracking, which can be accessed via the cloud platform. In summary, the proposed new combination of RFID, GPS, and IoT technologies for medical specimen logistic system can make better and simpler system for specimen transportation and management.

Published: September 2023

Aim: To investigate the implant stability in relation to two different implant designs, a cylindrical shaped single threaded design (CS/ST) and a tapered shaped double threaded design (TS/DT) using RFA over the first 8 weeks. Materials and Methods: 28 implants were randomly allocated into two groups and were placed as single tooth implant in the posterior arch. CBCT scan was used to determine the bone density and the implants were placed with guided surgical template by inexperienced surgeons which were prepared with the same implant planning software. The implant stability was measured using the RFA over the first 8 weeks at 3 points intervals. A mean ISQ value was recorded at each time points. The first ISQ of each implant recorded at the time of implant placement were the so-called primary stability. Results: A similar pattern of implant stability changes was observed. A significant decreased was found at the first four weeks after implantation (P<0.05) before ascending to maximum cumulative stability by the 8th week (p<0.05). Between the 2 groups, TS/DT group had a higher mean ISQ values at all three observation periods but did not reach statistical significance (P=0.69). Regarding different types of bone, TS/DT showed a significant difference in mean ISQ values in D4 bone. Conclusions: The difference in implant design did not significantly influence the implant stability however, TS/DT shows superiority over CS/ST when placed in D4 bone.

Published: September 2023

The purpose of this research is to understand more about the statistical seismology of the Thailand-Laos-Myanmar border in order to monitor earthquake activity and locate potentially dangerous area. The seismicity data was collected from the Thailand Meteorological Department. Following that, the catalog's homogeneity and completeness were improved. The first step is to identify the earthquake activity by using the adaptive frequency-magnitude distribution. The results are that Nan province, Thailand, and south Luang Prabang, Laos are the highest activity areas which can generate a maximum magnitude of 5.1 ML, 5.6 ML, 6.3 ML, and 6.7 ML in 5, 10, 30, 50 years. The return period with the ML of 4.0, 5.0, 6.0, and 7.0 was 1, 5, 20, and 75 years. The probability of the occurrence of the earthquake with the ML of 4.0, 5.0, 6.0, and 7.0 was 100%, 100%, 70-100%, and 20-60%, respectively. Then, identify the prospective area using three methods: b value, Z value , and RTL algorithm. After performing iterative tests on three methods with the appropriate parameterd, reasonable estimates of the anomalous precursors. Overlaying maps of those three methodologies makes it possible to identify prospective places for a coming major earthquake. The Thailand-Myanmar border region, Nan province, Thailand, and southwest of Luang Prabang, Laos are the most risk areas for the earthquake in the future.

The purposes of this study are to establish the detail lithology, stratigraphy, lithofacies and systematic paleontology of marine Silurian-Devonian sedimentary rocks of the Thong Pha Phum Group in Ban Tha Kraden, Si Sawat District, Kanchanaburi Province, and to interpret and reconstruct its depositional environment.

The Thong Pha Phum Group is well exposed in the study area. It consists mainly of shale, siltstone, sandstone, limestone, argillaceous limestone, calcareous shale, calcareous mudstone, and laminated mudstone with the many fossils such as graptolites, tentaculites, ostracods, brachiopods, nautiloids and trilobites. These strata are conformably underlain by the Thung Song Group (Ordovician age) and are conformably overlain by the Khuan Klang Formation (Early Carboniferous age). Abundant tentaculites were recognized and they consist of 7 species belonging to 3 genera: Nowakia acuaria, Nowakia (Cepanowakia) pumilio, Styliolina fissurella, Styliolina clavulus, Styliolina sp. A, Homoctenus tikhyi, and Homoctenus arctus indicating Early to Late Devonian age. In addition, graptolites (Monograptus sp. and Diplograptus sp.) were found in this area and they indicate probably Silurian? to Early Devonian. Based on the lithology, lithofacies, sedimentary structure, and fossils contains, they suggest that the Thong Pha Phum Group was deposited on the slope environment to deep marine basin in low energy conditions.

Published: September 2023

Many people living with HIV (PLWH) have cognitive impairment. Details of cognitive impairment subtypes are lacking. Unsupervised machine learning (ML) can reveal hidden subgroups within heterogeneous data. The study aimed to determine clusters of aging Thai PLWH with borderline cognitive impairment using unsupervised ML. HIV-NAT 207 study enrolled Thai PLWH aged ≥50 years. Cognitive performance was evaluated by the Thai-validated Montreal Cognitive Assessment (MoCA). This study included participants who scored between 23 and 27. The score of each cognitive domain served as cluster variables for the K-means algorithm. Among 340 PLWH, 177 (52.1%) scored between 23 and 27. Median age was 54 (IQR = 51-58) years, 118 (66.7%) were male, median CD4 was 620 (IQR = 489-795) cells/µL, and 170 (96.1%) were virally suppressed. K-means cluster demonstrated five clusters of all participants: 22.0% cluster 1 (marked memory with mild language impairment), 25.4% cluster 2 (mild visuospatial/executive function-language-memory impairment), 19.2% cluster 3 (moderate abstraction with mild visuospatial/executive function-language-memory impairment), 18.6% cluster 4 (marked language with mild memory impairment), 14.7% cluster 5 (marked language-abstraction impairment). A longitudinal study is warranted to identify differences in clinical significance and prognosis between each cluster.

Authors:   , Aksorn Satja 
Published: September 2023

The bioponic system is a system that utilizes biological waste as a nutrient-rich source such as chicken manure fertilizer for plant growth integrated with aquaponic. At present, chicken manure fertilizer is contaminated with Cu and Zn may have the potential health effects through vegetable consumption. The objective of this study was to evaluate nitrogen transformation, nitrogen recovery, and plant growth in chicken manure-based bioponics at Cu (50–150 mg/kg) and Zn (200–600 mg/kg) supplementation and investigate the effects of Cu and Zn supplementations on plant bioaccumulation, root microbial community, and dietary health risk. Cu and Zn concentrations were analyzed using inductively coupled plasma-optical emission spectrometry (ICP-OES). The result found that the average TKN was ranged from 11.2 ± 0.5 to 19.4 ± 1.8, TAN was 1.1 ± 0.8 to 1.5 ± 1.8 and NO3¯ was 11.6 ± 4.0 to 14.9 ± 4.7 mgN/L for lettuce cultivated, while pak choi cultivated TKN was ranged from 16.3 ± 0.1 to 19.4 ± 1.8, TAN was 0.7 ± 0.4 to 0.9 ± 0.5 and NO3¯ was 8.8 ± 6.8 to 10.1 ± 6.8 mgN/L respectively. These studies have shown that heavy metal contamination in chicken manure does not significantly affect nitrogen concentration and nitrogen use efficiency by plants ( significant level p < 0.05). The concentrations of Cu and Zn were found in lettuce shoot and root ranged 5.6 ± 0.1 to 7.2 ± 1.0 mg/kg and 64.8 ± 13.8 to 89.9 ± 2.6 mg/kg, while in pak choi was ranged 1.3 ± 0.3 to 4.1 ± 2.9 mg/kg and 43.3 ± 1.5 to 119.8 ± 34.1 mg/kg, respectively. Furthermore, the relative abundance of bacterial communities of lettuce and pak choi roots-based bioponics at phylum level was found Proteobacteria and Planctomycetes are dominant highest relative abundance respectively. However, the result of the health risk assessment was showed that HQ and HI < 1, which does not exceed the acceptable level. This study indicated that consuming lettuce and pak choi-based bioponic systems did not cause any human health effects or health risks to children and adults.

Authors:   , Tawonwong Tanawat 
Published: September 2023

The Varian ProBeam compact was installed at Her Royal Highness Princess Maha Chakri Sirindhorn Proton Center. Since 2017, the project has started at the King Chulalongkorn Memorial Hospital and after 4 years, during Covid19 pandemic, the 1st patient treatment received proton therapy on August, 2021. The radiation safety of the center was accomplished through firstly, the shielding calculation and secondary, the radiation survey at the milestone points such as cyclotron installation and 1st Beam ON at the treatment room. The only one WENDI-II dosimeter was used in radiation survey. The main purpose of this study is to validate the in-house neutron moderator based on CR-39 detector, Chulalongkorn University Neutron Moderator (CUMOD) through the ambient dose equivalent measurement, H*(10) and designed to use with proton pencil beam scanning, PBS of energy up to 250 MeV. The PHITS MC was used to simulate the neutron response function of CUMOD. The calibration of CUMOD was performed using 241AmBe source in the range of 100 to 1000 µSv. The H*(10) from CUMOD were compared with the one from WENDI-II. The variation of neutron fields was generated from various proton plans to cover most of the clinical scenarios. The linearly relationship between CUMOD and WENDI-II was observed with the factor of 0.64. The H*(10) per therapeutic dose was in the range of 0.018 to 0.105 mSv/Gy for 10 * 10 cm2 at 1 m distance. The advantage of CUMODs is the ability to measure H*(10) in various positions instantaneously.
Dosimetric impact of interplay effects inStereotactic Body Radiation Therapy (SBRT) lung cancer
Authors:   , Poolnapol Vanida 
Published: September 2023

Lung cancer patient breathing induced interplay effects in the volumetric modulated arc therapy (VMAT) together with stereotactic body radiation therapy (SBRT), which lead to non-uniform doses within the target volume and unwanted dose to the surrounding tissues. The purpose of this study was to investigate the dosimetric impact of interplay effects in 6 MV FFF of photon beams for lung cancer and to calculate the novel interplay effects factor (IEF) for VMAT-SBRT lung cancer. This study performed the static and dynamic measurements using two dimensions (2D) robotic platform and diode array for 3D-conformal radiation therapy (3D-CRT) plans, while using three dimensions (3D) CIRS dynamic thorax phantom and EBT3 films, and CC01 ionization chambers for VMAT-SBRT plans. The 3D-CRT results, the 1%, 1mm of gamma passing rates decreased for higher amplitudes. However, gamma passing rates increased with larger field sizes. For other parameters, no interplay effect was detected. The VMAT-SBRT results showed that higher amplitudes, more dimensions, and smaller doses are more pronounced. Therefore, the IEF calculation parameters consisted of these three mentioned factors. The 10.13 was the suitable number to be used as the cut point of lung VMAT-SBRT for applying respiratory motion management. The interplay effects for 6 MV FFF photon beams in VMAT-SBRT lung cancer are more impacted for the higher amplitudes and dimensions, and the smaller doses. The breathing amplitudes above 5 mm lead to significant changes in the shape of dose distribution due to the interplay effects, especially for 3D movements. The novel interplay effects factor (IEF) is a parameter that can indicate the interplay effects directly for VMAT-SBRT lung cancer patients. The value of 1 is the ideal score of IEF, while a value more than 10.13 is the score that can imply the need of respiratory motion management. However, the score is lower than 10.13, but that case provides some tumor motion that exceeds 5 mm in all directions, the need for respiratory motion management was also recommended.
