This study showed oral healthcare and nursing students' weak points regarding their attitudes and knowledge of oral health care at early stages. Oral health academic staff and professionals should develop effective oral healthcare curricula for oral healthcare students and help nursing staff develop a collaborative nursing oral healthcare curriculum to motivate nursing students.
BackgroundWe have started clinical application of 8K ultra-high definition (UHD; 7680 × 4320 pixels) imaging technology, which is a 16-fold higher resolution than the current 2K high-definition (HD; 1920 × 1080 pixels) technology, to an endoscope for advanced laparoscopic surgery.ResultsBased on preliminary testing experience and with subsequent technical and system improvements, we then proceeded to perform two cases of cholecystectomy and were able to achieve clinical success with an 8K UHD endoscopic system, which consisted of an 8K camera, a 30-degrees angled rigid endoscope with a lens adapter, a pair of 300-W xenon light sources, an 85-inch 8K LCD and an 8K video recorder. These experimental and clinical studies revealed the engineering and clinical feasibility of the 8K UHD endoscope, enabling us to have a positive outlook on its prospective use in clinical practice.ConclusionsThe 8K UHD endoscopy promises to open up new possibilities for intricate procedures including anastomoses of thin nerves and blood vessels as well as more confident surgical resections of a diversity of cancer tissues. 8K endoscopic imaging, compared to imaging by the current 2K imaging technology, is very likely to lead to major changes in the future of medical practice.
Background The relationship between oral and cognitive functions among older people is highly debated. Objective To examine whether oral functions are related to changes in the levels of mild cognitive impairment (MCI) biomarkers in older Japanese outpatients. Methods This observational study included 52 outpatients aged ≥65 years who underwent dental examinations at the Fukuoka Dental College Hospital. The Mini‐Mental State Examination (MMSE) was performed, and MCI blood biomarker levels were assessed at baseline and after 2 years. The present dental and periodontal conditions and the oral functions (tongue pressure and masticatory performance) were evaluated. Changes in parameters from baseline to follow‐up were compared using the Wilcoxon signed‐rank test, McNemar test or chi‐squared test. Associations among changes in the parameters were analysed using Spearman's rank correlation coefficient. Results The follow‐up rate in this study was 67%. The masticatory performance was improved (p < 0.001), whereas gingival inflammation was decreased (p < 0.001) over the 2‐year period. A significant increase in the MMSE score (p < 0.001) and a decrease in MCI risk (p < 0.001) were noted. The decrease in MCI risk was correlated with the increase in both masticatory performance (ρ = −0.34; p < 0.05) and MMSE score (ρ = −0.56; p < 0.01). Conclusion A decrease in MCI risk, as demonstrated by the levels of the blood biomarkers, was correlated with an increase in the masticatory performance in Japanese outpatients.
This study investigates the effects of a study course in oral health care on the perceptions of nursing students. The course was designed and evaluated by a multi-professional team at a Japanese nursing school. Method:The subjects were 119 nursing students. They participated in the oral health course that comprised 45h of training in 4 years. These were designed and taught by oral health professionals, a certified speech-hearing therapist, and nurses. Questionnaires were distributed to subjects to compare their perceptions and awareness about oral health care before, in between, and after the courses.A chi-square test was used to compare the data. Results: After completing the courses, more than 95% of the participants were interested in the oral health care practice and expected to collaborate with oral health professionals after getting qualified. Additionally, they understood the effectiveness of oral health care for the prevention of aspiration pneumonia and perceived that oral health care should be provided to hospitalized patients and community-dwelling older adults. Their awareness of the need to learn techniques for tooth brushing support, salivary gland massage, oral management, swallowing training, removing tongue coating, and gargling, both in theory and practice, was significantly improved. Conclusion: Multi-professional education has the potential to improve the awareness of nursing students of oral health care and promote collaborative oral health care in the future.

Obtaining access to the peritoneal cavity in laparoscopic surgery is more difficult in morbidly obese people. The aim of this study was to examine the safety and efficacy of accessing the peritoneal cavity using an optical, bladeless trocar without previous pneumoperitoneum in morbidly obese patients. The patients' characteristics and outcomes with consecutive and preferential use of an optical, bladeless, first trocar insertion without previous pneumoperitoneum in morbidly obese patients (body mass index > 35 kg/m2) was reviewed. A total of 208 morbidly obese patients were included. The trocar insertion technique was used in 196 patients. No bowel or major abdominal vessel injuries occurred. Ninety-eight patients (50%) had previous abdominal operations. Trocar-related injuries occurred in 3 patients: a superficial mesenteric laceration in 2 and a laceration of a greater omentum vessel in 1. The direct first trocar insertion technique provides safe entry into the peritoneal cavity in morbidly obese patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
