This study aimed to investigate the performance of oral assessment and health care education at nursing schools across Japan to identify problems and the need for oral health professional support.

This study aimed to investigate nurses’ perceptions of oral health care provision to inpatients in Japanese hospitals and the infection control measures taken by them after the coronavirus disease 2019 (COVID-19) lockdown to promote collaborative oral health care.

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. 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. 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. 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.

Collaborative oral health care among health‐care workers (HCWs) is important to prevent oral and systemic diseases. The purpose of this study was to investigate the perceptions, attitudes and performance of HCWs regarding collaborative oral health care and to compare them among HCWs. The subjects were dentists (DTs), dental hygienists (DHs), hospital nurses (HNs), speech–language–hearing therapists (STs) and certified care workers (CCWs) in Fukuoka Prefecture, Japan. DTs were members of the Fukuoka Dental Association, and DHs worked in dental clinics. HNs worked in hospitals without dental departments. STs and CCWs were members of professional associations. Data were collected by a mail survey. The chi‐square test and Kruskal–Wallis test were used to compare the data among HCWs. A total of 119 DTs, 91 DHs, 229 HNs, 119 STs and 121 CCWs participated in this study. The total response rate was 20.6%. There were significant differences in perceptions of what should be performed as part of oral health care among HCWs. Only 20%–60% of HCWs performed collaborative oral health care, while more than 75% were willing to perform such care. Levels of collaborative oral health care with other types of professionals and positive willingness to perform such care were lower among HNs than among the other HCWs. It is suggested that oral health professionals should recognise the presence of differences in the perceptions, attitudes and performance among other types of HCW and try to improve these to promote interprofessional collaboration of oral health care in hospitals.

We developed a new ultrahigh-sensitive CMOS camera using a specific sensor that has a wide range of spectral sensitivity characteristics. The objective of this study is to present our updated endoscopic technology that has successfully integrated two innovative functions; ultrasensitive imaging as well as advanced fluorescent viewing. Two different experiments were conducted. One was carried out to evaluate the function of the ultrahigh-sensitive camera. The other was to test the availability of the newly developed sensor and its performance as a fluorescence endoscope. In both studies, the distance from the endoscopic tip to the target was varied and those endoscopic images in each setting were taken for further comparison. In the first experiment, the 3-CCD camera failed to display the clear images under low illumination, and the target was hardly seen. In contrast, the CMOS camera was able to display the targets regardless of the camera-target distance under low illumination. Under high illumination, imaging quality given by both cameras was quite alike. In the second experiment as a fluorescence endoscope, the CMOS camera was capable of clearly showing the fluorescent-activated organs. The ultrahigh sensitivity CMOS HD endoscopic camera is expected to provide us with clear images under low illumination in addition to the fluorescent images under high illumination in the field of laparoscopic surgery.

Sodium-glucose cotransporter-2 (SGLT2) inhibitors have been reported as possibly associated with Fournier’s gangrene (FG). This case report describes a 34-year-old Japanese man who was diagnosed with FG after the administration of empagliflozin for type 2 diabetes mellitus (T2DM). He presented with pain and swelling in the perineum and groin 142 days after initiating empagliflozin. The clinical features, laboratory data, and computed tomographic findings were consistent with FG. Surgical drainage and debridement of necrotic tissues were performed immediately after admission to our hospital. The patient had no complications of diabetes before the onset of FG. Glycemic management was good at the time of FG onset. This case suggests a possible association between empagliflozin and FG. We report a case of FG in a patient during a period of good glycemic management following treatment with empagliflozin. We recommend further awareness of this relationship and suggest the need for additional research.
