  • Based on advances in biotechnology and neuroscience, neuromodulation is poised to gain clinical importance as a treatment modality for psychiatric disorders. In addition to old-established electroconvulsive therapy (ECT), clinicians are expected to understand newer forms of neurostimulation, such as deep brain stimulation (DBS), vagus nerve stimulation (VNS), repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS) and transcranial alternating current stimulation (tACS). Given the growing interest in non-invasive neuromodulation technologies, clinicians may seek sufficient information about neuromodulation to inform their clinical practice. A growing literature suggests that applications of non-invasive neuromodulation have evidence particularly for indications where treatments are currently insufficient, such as drug-resistant depression. However, positive neuromodulation studies require replication, and the precise interactions among stimulation, antidepressant medication, and psychotherapy are unknown. Further studies of long-term safety and the impact on the developing brain are needed. Non-invasive neuromodulatory devices could enable more individualized treatment. However, do-it-yourself (DIY) stimulation kits require a better understanding of the effects of more frequent patterns of stimulation and raise concerns about clinical supervision, regulation, and reimbursement. Wide spread enthusiasm for therapeutic potential of neuromodulation in clinical practice settings should be mitigated by the fact that there are still research gaps and challenges associated with non-invasive neuromodulatory devices.

  • The aim of the present study was to compare the non-invasive methods for the diagnosis of H. felis with HpSA kit-based detection method and H. felis-specific PCR assay with dog's stool samples without sacrifice. Male Beagle dogs (n=6) were infected with H. felis ATCC 49179 ($1.0{\times}10^9CFU/dog$) by intra-gastric inoculation two times at 3-day intervals, and the stool specimens of dogs were collected 1, 3, 5, 7, 14, 21 days after infection to submit to HpSA test and H. felis-specific PCR. As the results, the sensitivity of the HpSA and the PCR analysis was 50.0%, 83.3% respectively. Although HpSA test is less sensitive, it could be used for rapid, cheap and easy screening assay for H. felis infection in dog and cats. We suggest that the H. pylori stool antigen kit, HpSA, is useful and effective for monitoring H. felis infection. If HpSA test would be made with H. felis antibodies in the future, its sensitivity could be increased. Also, PCR assay could be successfully used to detect the H. felis in stools. Applying the H. pylori stool antigen kit and PCR assay may be the recommended non-invasive strategy to identify H. felis in dog and cats.

  • A new approach was proposed in this article, named, a non-invasive ultrasonic method to monitor the urinary bladder internal pressure which can resolve the shortcomings of the existing methods. The proposed method makes use of acoustic cavitation. It is based on a physical phenomenon that an extracorporeal high intensity focused ultrasonic pulse generates bubbles inside the urinary bladder and the dynamic properties of the bubbles are related to the urinary bladder internal pressure. The article presents the theoretical foundation for the proposed technique and verifies its feasibility with preliminary experimental data. The suggested ultrasonic urinary bladder internal pressure monitoring method is non-invasive and can be used any time regardless of sex and age, so that it will be of a great benefit to the diagnosis and therapy of urination related diseases.

  • Among non-invasive blood glucose detection technologies, the optical technique is a method that uses light reflection, absorption, and scattering characteristics when passing through a biological medium. It reduces pain or discomfort in measurement and has no risk of infection. So it is becoming a major flow of blood glucose detection research. Among them, near-infrared spectroscopy has a disadvantage in that the complexity increases when analyzing signals detected due to interferences between proteins and acids that share a similar absorption function with blood glucose molecules. In this study, a non-invasive sensor system with multiple near-infrared bands was designed and manufactured to alleviate the deterioration of blood glucose detection function that may occur due to skin absorption of near-infrared rays. A blood survey was conducted to verify the system, and the degree of blood glucose response in the blood was collected as spectral data, and the results of this study were quantitatively verified in terms of correlation between the data and blood glucose.

  • Objectives : The aim of this study was to develop a clinical pathway (CP) model for the integrative treatment of non-invasive breast cancer, with western medicine and Korean traditional medicine. Methods : The checklist model was composed in four types according to the target patients: DCIS inpatients, DCIS outpatients, LCIS inpatients, LCIS outpatients. The vertical axis of the pathway consists of 11 categories of actions applied to the patient. The horizontal axis was in accordance with the flow of time, comprising three periods during inpatient care and seven periods during outpatient care. In addition, CP was also composed in flow chart form. The pathway model was developed through a literature review of clinical practice guidelines, conference publications, papers, books, and websites. Results : The integrative CP model for non-invasive breast cancer was developed. Conclusions : The goal of the CP suggested in this study was to improve non-invasive breast cancer patients' quality of life and to supplement conventional treatment, by alleviating the side effects. The model developed through this study could serve as the basis when developing CPs in a real-world integrative medical environment. This could lead to a reduction in cost and time for CP development, thus bringing about efficiency in the clinical setting.

  • Purpose: Prevention of pancreas-related complications after gastric cancer surgery is critical. Polyglycolic acid (PGA) mesh reduces postoperative pancreatic fistula formation following pancreatic resection. However, the clinical efficacy of PGA mesh in gastric cancer surgery has not been adequately investigated. Materials and Methods: This retrospective study compared the short-term outcomes between two groups: patients who underwent minimally invasive R0 gastrectomy for gastric cancer with the use of a PGA mesh (PGA group) and those without the use of a PGA mesh (non-PGA group) at the Cancer Institute Hospital, Tokyo, between January 2019 and May 2023. Propensity score matching (PSM) was performed to adjust for the possible confounding factors. Results: A total of 834 patients were initially included, of whom 614 (307 in each group) remained after PSM. The amylase levels in the drained abdominal fluid on postoperative days 1 and 3 were similar between the PGA and non-PGA groups. The PGA group had a significantly lower incidence of pancreas-related complications of Clavien-Dindo grade ≥2 than that in the non-PGA group (6.8% vs. 2.9%, P=0.025). In subgroup analyses, the odds ratio for pancreas-related complications appeared to be better in the PGA group than in the non-PGA group in patients with American Society of Anesthesiologists Physical Status Classification score of 2 or 3, those operated via a laparoscopic approach, and those undergoing procedures other than proximal gastrectomy. Conclusions: The use of PGA mesh significantly reduced pancreas-related complications after minimally invasive surgery for gastric cancer and might thus benefit patients at risk of such complications.

  • Objective: To evaluate the relationship between serum neutrophil-to-lymphocyte ratio (NLR) and severity of meconium aspiration syndrome (MAS). Methods: We retrospectively analyzed 197 neonates who admitted for MAS between 2008 and 2016 at the neonatal intensive care unit of Dong-A University Hospital. The serial changes of NLR were analyzed from 1st to 3rd day of life. The NLR was compared by disease severities (non-invasive respiratory care group vs. invasive respiratory care group and MAS with or without persistent pulmonary hypertension of the newborn [PPHN]). Results: The NLR values from 1st to 3rd day of life significantly increased and then decreased (P=0.031). The NLR of invasive respiratory care group was significantly higher than non-invasive respiratory care group at 2nd, 3rd, and average of 1 to 3 days of life. The NLR of PPHN group was significantly higher than without PPHN group at 3rd, and average of 1 to 3 days of life. Conclusion: The NLR was significantly increased and then decreased in early stage of MAS and associated with the severity of MAS.

  • A vascular flora survey was conducted in 2020 to identify flora and analyze changes in the numbers of vascular flora species over the past 10 years at Gongju-weir (GW) and Baekje-weir (BW) in the Geumgang River, Republic of Korea. A total of 241 taxa were found in GW and 279 taxa in BW, and 208 taxa (88% of total taxa) were common species. The distribution of invasive species in GW and BW were seven and eight taxa, respectively. Rare plants were not identified in any of the weirs. The Poaceae family dominated in terms of number of species, followed by Asteraceae, Legumes, Cyperaceae, and Polygonaceae. Additionally, Therophytes accounted for a high proportion of Raunkiaer life forms. The numbers of vascular plant species, total taxa, naturalized plants, and invasive species have been increasing over the last 10 years. However, long-term alterations in invasive species before and after the opening of the weirs increased much more significantly in the partially opened BW than in the fully opened GW. These results indicate that the degree of barrier opening does not affect the invasion and establishment of non-native species.

  • Malignant meningiomas often show invasive growth that makes complete tumor resection challenging, and they are more prone to recur after radical resection. Invasive meningioma associated transcript 1 (IMAT1) is a long noncoding RNA located on Homo sapiens chromosome 17 that was identified by our team based on absolute expression differences in invasive and non-invasive meningiomas. Our studies indicated that IMAT1 was highly expressed in invasive meningiomas compared with non-invasive meningiomas. In vitro studies showed that IMAT1 promoted meningioma cell invasion through the inactivation of the Krüppel-like factor 4 (KLF4)/hsa-miR22-3p/Snai1 pathway by acting as a sponge for hsa-miR22-3p, and IMAT1 knockdown effectively restored the tumor suppressive properties of KLF4 by preserving its tumor suppressor pathway. In vivo experiments confirmed that IMAT1 silencing could significantly inhibit the growth of subcutaneous tumors and prolong the survival period of tumor-bearing mice. Our findings demonstrated that the high expression of IMAT1 is the inherent reason for the loss of the tumor suppressive properties of KLF4 during meningioma progression. Therefore, we believe that IMAT1 may be a potential biological marker and treatment target for meningiomas.
