Gout is the most common inflammatory arthritis among Filipinos, characterized by hyperuricemia leading to mono- sodium urate crystal deposition and an ensuing inflammatory response. Though typically a disorder of middle- aged and older adults, tophaceous gout presenting before the age of 30 is rare and suggests aggressive disease progression. Allopurinol, a first-line urate-lowering therapy, is generally effective but may cause rare, potentially life-threatening adverse reactions such as allopurinol hypersensitivity syndrome (AHS). Febuxostat, a non-purine xanthine oxidase inhibitor, is an alternative for patients intolerant to allopurinol. Although hypersensitivity reactions to febuxostat are extremely rare, isolated case reports document their occurrence in both patients with prior AHS and in allopurinol-naïve individuals. Hypersensitivity to both agents is exceedingly uncommon and presents a major therapeutic challenge. In such cases, febuxostat desensitization, conducted in collaboration with allergy specialists, may permit a viable solution to safely reintroduce urate-lowering therapy and prevent further disease progression. This case report describes a patient with young-onset, tophaceous gout who developed severe hypersensitivity reactions to both allopurinol and febuxostat — an unusual and challenging therapeutic dilemma. The case highlights the need for individualized management strategies, including the consideration of drug desensitization, in patients with limited urate-lowering options.

Background: Remimazolam is a novel short-acting benzodiazepine that has recently been used for general anesthesia. This study compared the safety and efficacy of remimazolam-based total intravenous anesthesia (TIVA) and volatile agent-based anesthesia in adults undergoing general anesthesia. Methods: We searched electronic databases including PubMed, Embase, CENTRAL, and Scopus for relevant studies. The primary outcome was the proportion of patients who experienced hypotension during surgery. Secondary outcomes included incidence of bradycardia, extubation time, duration in the post-anesthesia care unit hospital stay, and incidence of postoperative nausea and/or vomiting (PONV). We estimated the relative risk (RR) and mean difference with 95% CIs using a random-effects model. Results: A total of 969 patients from 12 randomized controlled trials were included. The incidence of hypotension was 14% and 34% in the remimazolam and volatile agent groups, respectively. Remimazolam significantly lowered the incidence of hypotension (RR: 0.43, 95% CI [0.29–0.63], P = 0.0000, I2 = 26%). The remimazolam group had a PONV incidence of 13%, compared to 28% in the volatile agent group, indicating a significant difference (RR: 0.51, 95% CI [0.37–0.72], P = 0.0001, I2 = 15%). No significant differences were observed in the other outcomes. Conclusions Remimazolam-based TIVA demonstrated favorable hemodynamic effects, with a lower incidence of hypotension and similar bradycardia rates, compared to volatile agent-based anesthesia. Furthermore, the reduction in PONV supports the use of remimazolam-based TIVA as a valuable method for general anesthesia.

Objectives: The purpose of this study was to examine the influence of the local Vietnamese government initiative, the ‘invisible healthcare system’, on the activities of Organization A, which focuses on oral health projects. Methods: Since 2000, Organization A has conducted preventive care and oral health-focused activities in central Vietnam, with formal and informal interventions from local Vietnamese governments. This study conducts an in-depth analysis of the relationship between local Vietnamese governments and oversea non-government organizations (NGOs) from the perspective of the recipient country. Results: First, the initial step involves aligning intentions with the local Vietnamese government through negotiations, such as reaching agreements on the operation of oral health programs. Second, efforts should be made to understand the implicit aspects of Vietnamese policies regarding oversea NGO activities. For instance, it can be the People’s Aid Coordination Committee (PACCOM), which has a policy to manage oversea NGOs. The policies of PACCOM inherently reflect an ‘invisible healthcare system’ and a ‘nationalist-oriented character’. Conclusions Finally, oversea NGO activities in Vietnam increasingly require a focus on ‘localization’and ‘Vietnamization’ to effectively achieve the desired outcomes.

Objective: : Although Republic of Korea is an advanced country in medical technology with a successful treatment rate for serious diseases, such as cancer, and has improved technology for highly difficult surgery, many excellent medical doctors and physicians are struggling due to the recent unreasonable medical environment. Specialization in brain tumor surgery also faces challenges in Republic of Korea, including low financial incentives, legal threats, and limited career prospects. In response, the Korean Brain Tumor Society (KBTS) formed the Future Strategy Committee to assess these obstacles and propose solutions. Methods: : A survey was conducted among the KBTS members to understand their perceptions and concerns across different career stages. Results: : The findings revealed a decline in interest among chief residents in brain tumor surgery, owing to limited job opportunities and income prospects. Neurosurgical fellows expressed neutral satisfaction but highlighted challenges, such as low patient numbers and income. Faculty members with varying levels of experience echoed similar concerns, emphasizing the need for improved financial incentives and job stability. Despite these challenges, the respondents expressed dedication to the field and suggested strategies for improvement. Conclusion : The KBTS outlines a vision that focuses on practical excellence, comprehensive research, professional education, responsibilities, and member satisfaction. Addressing these challenges requires collaborative efforts among healthcare institutions, professional societies, and policymakers to support brain tumor specialists and enhance patient care.

Background: In recent years, scientists have found that certain natural compounds have significant potential in cancer prevention and early-stage cancer treatment. Flavanones, a class of polyphenolic compounds found in plants, vegetables, seeds, fruit peels, and flowers, have been identified to possess anticancer, antioxidant, anti- inflammatory, and antibacterial bioactivities. Cancer has become a major global challenge in terms of both economic and public health concerns. Global statistics indicate that 22.8% of deaths are attributed to non-communicable diseases, and 16.8% are caused by cancer, accounting for one in four and one in six deaths, respectively. Aim : To investigate anticancer effects of Iris Tenuifolia-derived flavanone on cancer cell lines. Materials and Methods : The study was conducted at the Bio-Medical Research Institute of the Mongolian National Uni versity of Medical Sciences, investigating the effect of flavanones on cancer cell viability under in vitro conditions using the MTT assay. In the study, colon, liver, and lung cancer cells were cultured, stabilized, and used for the experiments. Colorectal cancer cells (MC38), liver cancer cells (HepG2), and lung cancer cells (A549) were revived, cultured, and stabilized for use in the experimental procedures. Statistical analysis of the results was performed using Microsoft Excel 2010, and graphs were generated using GraphPad Prism 8. Differences between groups were analyzed using Student’s t-test, and a p-value of <0.05 was considered statistically significant. Results : We treated MC38, HepG2, and A549 cancer cells with different concentrations of flavanone (2.5 µM, 5 µM, and 10 µM) for 24 to 48 hours to evaluate cell viability. Flavanone inhibited A549 cell viability by 2.5 μM-10%, 5 μM-25%, and 10 μM-38%, respectively. For HepG2 cells, flavanone treatment at concentrations of 5-10 µM reduced cell viability by 28–58%. No statistically significant effect on the viability of MC38 cells was observed following treatment with flavanone at concentrations ranging from 2.5 to 10 µM. Additionally, although MC38 inhibited cell viability in a dose-de pendent manner in cell cultures, it had a statistically significant effect at higher concentrations of 30-200 μM (p<0.01). Conclusion Flavanone inhibits the cancer cell viability in a dose and time dependent manner

Background: The first confirmed case of COVID-19 in Mongolia was reported on November 11, 2020. In response, the government imposed a nationwide lockdown, which significantly impacted the population’s mental health. Heightened levels of stress, anxiety, loneliness, and depression during the pandemic altered individuals’ psychological stability and behavior. Personality traits—defined as relatively stable patterns of emotion, cognition, and behavior—play a key role in stress responses and emotional regulation under pressure. Emerging evidence suggests that these psychological factors may influence the immune system’s responsiveness, including vaccine-induced antibody production. Aim: To evaluate the association between post-vaccination antibody responses and personality types following two doses of COVID-19 vaccines. Materials and Methods: A total of 738 participants who received two doses of COVID-19 vaccines (AstraZeneca ChAdOx1, n=29; Pfizer-BioNTech, n=119; Sinopharm BBIBP, n=590) and had no prior SARS-CoV-2 infection were enrolled. Serum samples were collected 21–28 days after the second dose, and SARS-CoV-2 RBD (S) IgG antibodies were measured using ELISA (Proteintech Inc., USA). Personality types were assessed using a 56-item temperament questionnaire developed by A. Belov, categorizing individuals into classical temperament types (choleric, phlegmatic, sanguine, melancholic). Logistic regression and ROC analysis were used to examine associations between personality types and antibody response. Results: The presence of an antibody response was significantly higher among individuals with a melancholic temperament, and significantly lower among those with a phlegmatic temperament. Furthermore, antibody titers were higher in participants with melancholic and sanguine temperaments and lower in those with a phlegmatic type. Conclusions 1. During the early period following the second dose of COVID-19 vaccination, the antibody response was higher in individuals with a pure melancholic temperament, while it was lower in those with a phlegmatic temperament. 2. After the second dose of the Sinopharm BBIBP COVID-19 vaccine, antibody titers were higher in individuals with pure melancholic and sanguine temperaments, and lower in those with a phlegmatic temperament.

Background: The study of small-molecule compounds with antitumor activity involves several crucial steps. These include determining their selective effects on cancer cells, understanding the type of cell death they induce, identifying the activated signaling pathways, pinpointing the target molecules, and elucidating the mechanisms of action. Among the plant-derived compounds with anticancer properties, flavonoids are notable for their ease of isolation and their abundance in food. Apigetrin, a representative flavonoid, is a secondary metabolite found in plants, and our previous study indicated that its anticancer selectivity index was 13.1. However, the specific mechanism by which apigetrin inhibits leukemia cell growth remains unclear. Aim: To study of the inhibitory action of apigenin on leukemia cell culture Materials and Methods: In this study, we evaluated the apoptosis of cells using flow cytometry and investigated the in volvement of the caspase pathway through the use of pancaspase inhibitors to explore the effects of apigetrin on leukemia cell growth. Results: After incubating leukemia RAW264.7 cells with 30 μM apigetrin for 24 and 48 hours, we did not detect any apoptosis through Annexin V and PI staining by flow cytometry. We compared the number of viable cells using the MTT assay after 24-hour treatment of apigetrin with or without pretreatment of Z-VAD, a pancaspase inhibitor, for 30 minutes. The results indicated that the pancaspase inhibitor did not reduce the inhibitory effect of apigetrin on the growth of RAW264.7 cells. In contrast, the positive control group, treated with doxorubicin—which induces apoptosis—showed not only significant apoptosis but also a reduction of the pancaspase inhibitor on the cell growth inhibition. Therefore, these data suggested that apigetrin likely has a cytostatic effect or inhibits the cell cycle rather than being cytotoxic. Future research should focus on determining which stage of the cell cycle RAW264.7 cells treated with apigetrin are in, as well as studying the signaling pathways involved in the cell cycle. Conclusions Apigetrin inhibits the proliferation of RAW264.7 leukemia cells in a caspase-independent and non-apoptotic manner.
