The Prevalence of Binge Drinking and Alcohol-Related Consequences and their Relationship among Japanese College Students.
Binge drinking is a common and risky behavior among college students. In Japan, however, research on the prevalence of binge drinking and alcohol-related consequences, and the relationship between them, is currently scant. The aim of this study is to examine the status of binge drinking and alcohol-related problems, and the relationship between them, among Japanese college students. ⋯ Furthermore, logistic analysis revealed that among men, the B-YAACQ scores of binge drinkers were 2.01-fold higher those of non-binge drinkers. The findings of this study indicated that binge drinking may cause not only physical consequences but also mental and social problems, especially among men. It is important to tell college students these risks properly not to engage in binge drinking.

Aldosterone plays pivotal roles in renin-angiotensin-aldosterone system in order to maintain the equilibrium of liquid volume and electrolyte metabolism. Aldosterone action is mediated by both mineralocorticoid receptor and 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2). Its excessive actions directly induced tissue injuries in its target organs such as myocardial and vascular fibrosis in addition to chronic kidney diseases. ⋯ All these aldosterone-producing lesions were reported to harbor somatic mutations including KCNJ5, CACNA1D, ATP1A1 and ATP2B3, which were all related to excessive aldosterone production. Among those mutations above, somatic mutation of KCNJ5 is the most frequent in aldosterone-producing adenoma and mostly composed of clear cells harboring abundant aldosterone synthase expression. In contrast, CACNA1D-mutated aldosterone-producing micronodules or aldosterone-producing nodules were frequently detected not only in primary aldosteronism patients but also in the zona glomerulosa of normal adrenal glands, which could eventually lead to an autonomous aldosterone production resulting in normotensive or overt primary aldosteronism, but their details have remained unknown.

Tripartite Motif-Containing 44 is Involved in the Tumorigenesis of Laryngeal Squamous Cell Carcinoma, and its Expression is Downregulated by Nuciferine.
Tripartite motif-containing 44 (TRIM44) was reported to be involved in the tumorigenesis of several tumors, but its function in laryngeal squamous cell carcinoma has not been investigated yet. In the present study, we aimed to elucidate the function of TRIM44 in laryngeal squamous cell carcinoma, and identify the compounds which could inhibit TRIM44 expression. Our results showed that TRIM44 was upregulated in tumor tissues and cell lines of laryngeal squamous cell carcinoma. ⋯ Additionally, nuciferine markedly inhibited cell survival of laryngeal squamous cell carcinoma in a concentration-dependent manner. In contrast, TRIM44 overexpression significantly reduced the cytotoxicity of nuciferine in laryngeal squamous cell carcinoma cells. In conclusion, this study indicated that inhibiting TRIM44 would be a useful strategy for the treatment of laryngeal squamous cell carcinoma, and nuciferine could be a potential chemical applicated in the therapy of laryngeal squamous cell carcinoma.

Characteristics of Home-Visit Nursing Stations that Accept Children Requiring Long-Term Medical Care after Discharge from Neonatal Intensive Care Unit.
Many cultures are witnessing high-risk births due to the increasing trend of delayed childbearing. This has resulted in a higher proportion of children requiring long-term medical care (CLTM). The number of home-visit nursing stations available for pediatric patients should increase to provide care for CLTM at home. ⋯ Nonetheless, the number of facilities with pediatric departments has declined; thus, nurses will face increasing difficulty gaining pediatric work experiences. Therefore, enhanced seminars and training on pediatric medical care for managers and nurses, as well as strengthened collaboration/coordination with pediatric wards, clinics, and multidisciplinary occupations should be implemented as countermeasures. Our findings illustrate issues and strategies for acceptance.

Case ReportsThe Effect of Teriparatide for the Treatment of Multiple Spontaneous Clinical Vertebral Fractures after Discontinuation of Denosumab in a Female Patient with Rheumatoid Arthritis: A Case Report.
Discontinuation of denosumab is associated with the risk of rebound in bone turnover and rebound-associated spontaneous clinical vertebral fractures. This case report presents an 86-year-old woman with rheumatoid arthritis who experienced rebound-associated spontaneous clinical vertebral fractures at 9 months after denosumab discontinuation. Following 5-year bisphosphonate treatment, the patient had 9 injections of 60-mg denosumab every 6 months. ⋯ Teriparatide was effective for accelerating the fracture healing and suppressing the occurrence of new fractures. However, 2-year treatment of teriparatide did not have suppressive effect of rebound in bone turnover and general bone loss. This case suggested that teriparatide was effective for suppression of new rebound-associated spontaneous clinical vertebral fractures, but not effective in prevention of general bone loss after denosumab discontinuation.
