Probiotics such as bifidobacteria have been given to low-birth-weight neonates (LBWNs) at risk for a disrupted gut microbiota leading to the development of serious diseases such necrotizing enterocolitis. Recently prebiotics such as lactulose are used together with bifidobacteria as synbiotics. However, faster and more powerful bifidobacteria growth is desired for better LBWN outcomes. The prebiotic 1-kestose has a higher selective growth-promoting effect on bifidobacteria and lactic acid bacteria in vitro among several oligosaccharides. Twenty-six premature neonates (less than 2,000 g) admitted to a neonatal intensive care unit (NICU) were randomly assigned to receive Bifidobacterium breve M16-V with either 1-kestose or lactulose once a day for four weeks from birth. A 16S rRNA gene analysis revealed similar increases in alpha-diversity from 7 to 28 days in both groups. The most dominant genus on both days was Bifidobacterium in both groups, with no significant difference between the two groups. Quantitative PCR analysis revealed that the number of Staphylococcus aureus tended to be lower in the 1-kestose group than in the lactulose group at 28 days. The number of Escherichia coli was higher in the 1-kestose group at 7 days. The copy number of total bacteria in the 1-kestose group was significantly higher than that in the lactulose group at 3 time points, 7, 14, and 28 days. No severe adverse events occurred in either group during the study period. l-Ketose may offer an alternative option to lactulose as a prebiotic to promote the development of gut microbiota in LBWNs., Competing Interests: M. Takahashi, Y. Kadota, and T. Tochio are employed by B Food Science Co., Ltd., which produces the 1-kestose used in the present study.

The spread of COVID-19 has re-affirmed the crucial importance of the pharmaceuticals industry in improving the level of citizens' health and medical care, as well as the industry's importance in terms of contribution to economic growth and tax revenues. Although some time has passed since the importance of industry-academia collaboration was first raised in relation to the creation of innovative new drugs and the continuation of global competitiveness, conflicts between academia and companies have also been highlighted as barriers that hinder efforts to promote the practical realization of academia-initiated seeds. The authors have hypothesized that conflicts between academia and companies can be attributed to the vulnerability of innovation creation environments, including drug discovery, on the academia side, insufficient awareness concerning human resources that will undertake industry-academia operations, and inadequate development of structures. Consequently, we implemented fact-finding investigations in relation to universities and public research institutions in Japan, with the objective of ascertaining the actual status of innovation creation environments, including drug discovery, on the academia side. From the results of these investigations, we will clarify the issues that may present barriers to innovation creation, and consider policies, etc. for the enhancement of innovation creation environments.

A 77-year-old male with chronic hepatitis and liver cirrhosis underwent a right middle-lower lobectomy and lymph node dissection because of non-small cell carcinoma of the lung. On the 1st post-operative day (POD1), a large quantity of chylous pleural effusion was recognized after he initiated oral intake. The diagnosis was postoperative chylothorax. Conservative therapy including a medium chain tryglyceride diet and total parental nutrition were not effective. Considering of the patient's past history, we decided to continue conservative therapy using octreotide acetate on POD7. After administration of the octreotide acetate, the volume of chylous pleural effusion gradually decreased. The chest tube was removed on POD19. Octeotide acetate should be a choice for the conservative treatment of postoperative refractory chylothorax.
