Methods: Spine surgeons of the Asia–Pacific Spine Society were asked to respond to a web-based survey on IONM. The questionnaire covered various aspects of IONM, including its common modality, Tc-MEP details, necessities for consistent use, and recommended modalities in major spine surgeries and representative surgical procedures. Results: Responses were received from 193 of 626 spine surgeons. Among these respondents, 177 used IONM routinely. Among these 177 respondents, 17 mainly used SEP, whereas the majority favored Tc-MEPs. Although a >50% decrease is the commonly used alarm point in Tc-MEP, half of the Tc-MEP users had no protocols planned for such scenarios. Moreover, half of the Tc-MEP users experienced complications, with bite injuries being the most common. Most respondents strongly recommended IONM in deformity surgery for pediatric and adult populations and tumor resection surgery for intramedullary spinal cord tumors. Conversely, IONM was the least recommended in lumbar spinal canal stenosis surgery. Conclusions Spine surgeons in Asia–Pacific countries favored IONM use, indicating widespread routine utilization. Tc-MEP was the predominant modality for IONM, followed by SEPs.

Ovarian cancer, notable for its severe prognosis among gynecologic cancers, has seen substantial progress in treatment approaches recently. Enhanced protocols in chemotherapy and the introduction of poly (ADP-ribose) polymerase (PARP) inhibitors for maintenance therapy have markedly improved outcomes for patients with specific genetic profiles, such as those positive for BRCA mutations or exhibiting homologous recombination deficiency (HRD). Additionally, the method of intraperitoneal chemotherapy administration has emerged as a valuable alternative to traditional transvenous routes, showing promise for wider clinical adoption. The field of surgery has also evolved, with increasing exploration into the benefits and feasibility of laparoscopic methods over more invasive traditional surgeries, aiming for complete tumor removal but with reduced patient impact. The hereditary nature of ovarian cancer underscores the importance of genetic testing, which has become integral in tailoring treatment strategies, particularly in determining suitability for PARP inhibitors.The formation of the East Asian Gynecologic Oncology Trial Group (EAGOT) aims to optimize treatment across Japan, Korea, China, and Taiwan. The ovarian cancer committee of EAGOT shared the current policies, focusing on 5 topics: 1) strategies for maintenance therapy after initial surgery and chemotherapy, 2) drug regimens for platinum-sensitive and platinum-resistant recurrence, 3) intraperitoneal chemotherapy, 4) laparoscopic surgery as an alternative to laparotomy, and 5) current status of genetic testing (BRCA, HRD, and panel tests) for ovarian cancer and its prospects. EAGOT’s multi-national trials aim to harmonize these evolving treatment strategies, ensuring that the latest and most effective protocols are accessible across the region, thereby significantly impacting patient outcomes in East Asia.

With increasing global life expectancy, the significance of geriatric assessment parameters has increased. Sarcopenia is a crucial assessment parameter and is defined as the age-related loss of muscle mass and strength. Sarcopenia is widely acknowledged as a risk factor for postoperative complications in diverse advanced malignancies and has a detrimental effect on the long-term prognosis. While most studies have primarily concentrated on the correlation between sarcopenia and advanced cancer, more recent investigations have focused on the relationship between sarcopenia and early-stage cancer. Endoscopic submucosal dissection (ESD), which is less invasive than surgical intervention, is extensively employed in the management of early-stage cancer, although it is associated with complications such as bleeding and perforation. In recent years, several reports have revealed the adverse consequences of sarcopenia in patients with early-stage cancer undergoing ESD. This literature review briefly summarizes the recent studies on the association between sarcopenia and ESD.

Objectives: As the population ages worldwide, including in Japan, there is a growing expectation for older adults to remain active participants in society. The act of sharing one’s experiences and knowledge with younger generations through social engagement not onlyenriches the lives of older individuals, but also holds significant value for our society. In thisstudy, we examined both positive and negative perceptions of older adults and investigated the correlation between these perceptions and generativity among older citizens. Additionally, we evaluated the impact of life satisfaction on these factors. Methods: We conducted a survey of 100 older adults in Japan (mean age, 71.68 years) and utilized multiple regression analyses, using positive and negative perceptions of older adults, life satisfaction, and demographic factors as independent variables. The sub-categories of generativity—namely, generative action, concern, and accomplishment—were used as dependent variables. Results: Participants who held a more positive perception of older adults demonstrated a higher level of generative actions and concerns. Additionally, participants who reported higher levels of life satisfaction also exhibited more generative actions, concerns, and accomplishments. Conversely, those who held a more negative perception of older adults were found to have higher levels of generative actions. Conclusion Enhancing positive perceptions of older adults among them can boost the subcategories of generativity. This study, which was conducted from an exploratory perspective, has several limitations, including a potential sampling bias. A more comprehensive examination of the relationship between perceptions of older adults and generativity is anticipated in future research.

BACKGROUND: Systemic and local factors may lead to disruption of craniofacial growth and development, causing an imbalance between the orofacial skeleton, muscle and soft tissue, dental occlusion, and the dental arch during growth periods. We aimed to reveal whether the prevalence of incompetent lip seal (ILS) varies with age and region, as well as to clarify the factors related to an ILS, in a national, large-scale epidemiological study. METHODS: We surveyed 3399 children, from 3 to 12 years of age, visiting 66 pediatric dental clinics throughout Japan. For this survey, we employed a questionnaire consisting of 44 questions regarding daily health conditions and lifestyle habits. We evaluated the differences in ILS prevalence by age and region (using a Cochran-Armitage test for trend and a Kruskal-Wallis test), and the relationship between ILS and factors investigated in the questionnaire (using Spearman's rank correlation coefficient). RESULTS: We observed that 30.7% of Japanese children exhibited an ILS and that the ILS rate increased with age (p < 0.001). There were no regional differences in the rate of ILS in Japanese children (p = 0.506). We revealed that 12 of 44 survey items exhibited a statistically significant correlation with ILS (p < 0.001), using Spearman's rank correlation coefficient. These items involved orofacial morphology, mouth breathing, and possibly, allergic rhinitis. CONCLUSION The rate of ILS seems to increase with age in children, throughout Japan. Therefore, this disorder may not self-correct during the growth periods in these children. Guidelines are required for pediatric dentists to recognize ILS among children aged 3-12 years.

BACKGROUND/AIMS: To determine which drug-eluting stents are more effective in acute myocardial infarction (MI) patients with chronic kidney disease (CKD). METHODS: This study included a total of 3,566 acute MI survivors with CKD from the Korea Acute Myocardial Infarction Registry who were treated with stenting and followed up for 12 months: 1,845 patients who received sirolimus-eluting stents (SES), 1,356 who received paclitaxel-eluting stents (PES), and 365 who received zotarolimus-eluting stents (ZES). CKD was defined as an estimated glomerular filtration rate < 60 mL/min/1.73 m2 calculated by the modification of diet in renal disease method. RESULTS: At the 12-month follow-up, patients receiving ZES demonstrated a higher incidence (14.8%) of major adverse cardiac events (MACEs) compared to those receiving SES (10.1%) and PES (12%, p = 0.019). The ZES patients also had a higher incidence (3.9%) of target lesion revascularization (TLR) compared to those receiving SES (1.5%) and PES (2.4%, p = 0.011). After adjusting for confounding factors, ZES was associated with a higher incidence of MACE and TLR than SES (adjusted hazard ratio [HR], 0.623; 95% confidence interval [CI], 0.442 to 0.879; p = 0.007; adjusted HR, 0.350; 95% CI, 0.165 to 0.743; p = 0.006, respectively), and with a higher rate of TLR than PES (adjusted HR, 0.471; 95% CI, 0.223 to 0.997; p = 0.049). CONCLUSIONS: Our findings suggest that ZES is less effective than SES and PES in terms of 12-month TLR, and has a higher incidence of MACE due to a higher TLR rate compared with SES, in acute MI patients with CKD.
