Intrauterine fetal death due to fetal intracranial hemorrhage associated with maternal vitamin K deficiency: A case report.

Vitamin K deficiency can cause coagulopathy; therefore, supplementation is recommended to prevent intracranial hemorrhage in newborns. Some reports have shown that maternal vitamin K deficiency is associated with intracranial hemorrhage in the fetus. However, no clear guidelines exist for the diagnosis and treatment of maternal vitamin K deficiency to prevent fetal intracranial hemorrhage. We report a case of intrauterine fetal death due to intracranial hemorrhage associated with maternal vitamin K deficiency resulting from hyperemesis gravidarum. In this case, maternal protein induced by vitamin K absence II (PIVKA-II) was high at the time of intrauterine fetal death. Therefore, measuring maternal PIVKA-II levels in high-risk cases may help determine the timing of therapeutic interventions for vitamin K deficiency during pregnancy.

New approach to evaluate the lubrication process in various granule filling levels and rotating mixer sizes using a thermal effusivity sensor.

The principles of thermal effusivity are applied to an understanding of the detailed mechanisms of the lubrication process in a rotating mixer. The relationships and impact of the lubrication process by the pattern of powder flow, the filling level, and the rotating mixer size were investigated. Thermal effusivity profiles of the lubrication process, as obtained, indicate that lubrication is a two-phase process. The intersection point of the first and second phases (IPFS) is influenced by changing the filling level, thus changing the resulting number of avalanche flows created. The slope of the second phase (SSP) is influenced by the relationship between the number and the length of avalanche flows. Understanding this difference between the first and second phases is important to successfully evaluate the impact of proposed changes in the lubrication process. From this knowledge, a predictive model of the lubrication profile can be generated to allow an evaluation of proposed changes to the lubrication process. This model allows estimation of the lubrication profile at different filling levels and in different rotating mixer sizes. In this study, the actual lubrication profile almost coincides with the model predicted lubrication profile. Based on these findings, it is assumed that lubrication profiles at a commercial scale can be predicted from data generated at the laboratory scale. Further, it is assumed that changes in the filling level can also be estimated from the laboratory or current data.

[Possibility of exacerbation of allergy by lunar regolith].

Japan, U.S.A. and other foreign space agencies have plans for the construction of a lunar base and long-term stay of astronauts on the moon. The surface of the moon is covered by a thick layer of soil that includes fine particles called "lunar regolith", which is formed by meteorite impact and space weathering. Risk assessment of particulate matter on the moon is important for astronauts working in microgravity on the moon. However, there are few investigations about the biological influences of lunar regolith. Especially, there is no investigation about allergic activity to lunar regolith. The main chemical components of lunar regolith are SiO2, Al2O3, CaO, FeO, etc. Of particular interest, approximately 50% of lunar regolith consists of SiO2. There is a report that the astronauts felt hay fever-like symptoms from the inhalation of the lunar regolith. Yellow sand, whose chemical components are similar to lunar regolith, enhances allergenic reactions, suggesting the possibility that lunar regolith has an adjuvant-like activity. Although intraperitoneal administration of lunar regolith with ovalbumin to mouse did not show enhancement of allergenic reactions, further evaluation of lunar regolith's potential to exacerbate the effects of allergies is essential for development of the moon.

Endocrinological evaluations of brief hand massages in palliative care.

BACKGROUND AND OBJECTIVES: Some patients with advanced cancer make use of complementary therapies for the reduction of anxiety and stress. These patients can suffer distressing end-of-life symptoms, which conventional treatments might not relieve satisfactorily. Although previous studies have suggested that complementary therapies could be useful for reducing distress in patients with cancer, it has remained unclear whether these benefits are applicable at the end-of-life stage. The current study examined to validate salivary chromogranin A (CgA) as a biomarker for relieving stress by hand massage in terminally ill patients. METHODS: The study group comprised 34 inpatients in palliative care units. Each of these patients received a 5-minute massage to the upper extremity. Before and after the massage, saliva samples were collected in order to measure the CgA levels. RESULTS: The brief hand massage appears to reduce levels of stress according to the salivary CgA (p < 0.05). In addition, we found statistically significant changes in patient satisfaction with hand massage. CONCLUSIONS: Salivary CgA could potentially be used as a biomarker to measure relieving stress by hand massage in a palliative-care setting.

Attitudes toward and current practice of complementary and alternative medicine in Japanese palliative care units.

Complementary and alternative medicine (CAM) might enhance the quality of life of patients with cancer. The aim of this study was to investigate the current practice of CAM in Japanese palliative care units. A 17-item questionnaire was mailed to all 150 certified palliative care units in Japan, 80% of which responded. In total, 75 institutions (64%) provided at least one modality of CAM. Only 33% of the palliative care units surveyed had any regulations about patient usage of CAM, and 42% rejected some types of CAM because they caused difficulties for other patients (34%), required medical procedures (26%), used fire (5%), or required outside practitioners (4%). In total, 92% of surveyed palliative care units had no regulation and actually provided CAM. The obstacles to the use of CAM included the availability of certified practitioners, costs, added responsibilities for staff members, and insufficient evidence of efficacy. We concluded that Japanese palliative care units generally had a positive attitude toward CAM, and were willing to provide this type of therapy to patients.
