Tacrolimus is a potent immunosuppressive drug widely used to prevent and treat graft-versus-host disease (GVHD) in stem cell transplantation (SCT). Among 49 patients receiving tacrolimus who underwent SCT from January 2000 to July 2003, 10 patients (20%) developed encephalopathy. The commonly observed symptoms were convulsions and drowsiness, and most patients complained of signal symptoms such as headache, nausea, and cortical blindness before onset. The most common abnormality on neuroimages was high-intensity lesions in white matter on magnetic resonance imaging T2-weighted or fluid-attenuated inversion recovery images. At onset, all patients were receiving treatment for acute GVHD (grade II/III) or extensive chronic GVHD and demonstrated an abrupt increase in blood pressure from baseline levels. The serum tacrolimus concentration was generally within acceptable levels at onset. Symptoms gradually improved in all patients when the blood pressure was lowered with antihypertensive medication, regardless of continued tacrolimus administration following a short-term suspension. The pathogenesis of tacrolimus-related encephalopathy is multifactorial, although refractory GVHD and a sudden increase in blood pressure seem to be major predisposing factors. Because the withdrawal of tacrolimus or switching to less potent anti-GVHD agents usually worsens the GVHD, the administration of tacrolimus should be managed by closely monitoring serum levels and controlling blood pressure.

Transanal tube placement prevents AL after LLAR. Furthermore, this protective effect may be due to a reduction in the unfavorable incidence of early postoperative diarrhea.

A girl with congenital agammaglobulinemia and minor facial anomalies lacked B cells in peripheral blood: karyotypic analysis of white blood cells showed balanced translocation, t(9;20)(q33.2;q12). In the current study, we isolated a novel gene, leucine-rich repeat–containing 8 (LRRC8), at the translocation site on chromosome 9. It has four transmembrane helixes with one isolated and eight sequentially located leucine-rich repeats (LRRs) and constitutes a new protein family. It is expressed on T cells as well as on B-lineage cells. Translocation truncates the LRRC8 gene, resulting in deletion of the eighth, ninth, and half of the seventh LRR domains located close to the C-terminal. The truncated form of the LRRC8 gene is transcribed with sequences from the noncoding region adjacent to the truncated seventh LRR. Protein products derived from the truncated gene are coexpressed on white blood cells with the intact LRRC8 protein from the untranslocated allele. Transplantation experiments with murine bone marrow cells that were forced to express the truncated LRRC8 show that expression of the truncated protein inhibited B cell development. These results indicate that LRRC8 is responsible for the B cell deficiency in this patient and is required for B cell development

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.

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.

Background: Nurses' oral assessment and dental referral performance for inpatients are important to provide appropriate oral care services in hospitals. The purpose of this study was to investigate the knowledge, attitudes, and performance of oral assessments and dental referrals for their inpatients among nurses and to identify factors associated with that performance to promote oral health care in hospitals. Methods: All nurses (n = 919) who worked at five hospitals in Japan were recruited as responders. A questionnaire regarding their performance of oral assessments and dental referrals was distributed to the subjects in each hospital. The data were collected from August 2018 to September 2018. Results: A total of 757 (82.4%) nurses (82 males and 675 females) responded to the questionnaire. With respect to each of the 8 oral assessment categories, 16.2-41.2% of the nurses performed oral assessments for more than 50% of their inpatients, and 20.3-29.9% had encouraged more than one inpatient to see a dentist within the previous 3 months. Significant differences were found by ward and hospital in their performance of oral assessments for inpatients. Additionally, their oral assessment performance, knowledge of the usage of oral assessment tools, wards, and hospitals were significantly associated with their dental referral performance. Conclusions: The performance of oral assessment and dental referral was not developed sufficiently in the hospitals. Thus, oral health professionals should support oral assessment education for nurses, including usage of assessment tools, to promote dental referral by nurses. These results may contribute to promotion of dental referral performance by nurses and provision of oral health care by oral health professionals for hospital inpatients.
