Current dietary intake of the Japanese population in reference to the planetary health diet-preliminary assessment
IntroductionWe sought to assess the Japanese diet by examining the current dietary intake in Japan using the global reference diet from the EAT-Lancet Commission (Planetary Health Diet; PHD), from the perspective of protein intake in different age groups.MethodsAverage dietary intake by food group in the Japan National Health and Nutrition Survey 2019 (NHNS 2019) was converted to the PHD food groups, and the diet gap (DG) (%) of the global reference of the PHD was calculated by age group.ResultsAlthough the DG of the intake was excessive compared with the global reference of the PHD in most food groups in all age groups (7.1–416%), the intake exceeded the upper limit of the range only for red meat (640%). Red meat had the highest DG among subjects in their 40s, although the DG decreased with increasing age. Protein intake was within the possible range and did not greatly exceed the recommended dietary intake in the Japanese standard.DiscussionThe current Japanese diet contains an excessive intake of red meat in terms of the global reference of the PHD. This trend is similar to that previously reported in various western regions and countries. However, the Japanese diet does not significantly exceed the recommended protein intake for Japanese people, suggesting that the PHD is an environmentally friendly and healthy choice for younger and older age groups in an aging Japanese society. Policy makers need to develop sustainable and healthy food-based dietary guidelines in addition to providing food and nutrition education and developing a food environment that encourages sustainable and healthy choices to support dietary change
Initial Medical Errors After the Implementation of a Clinical Information System in an Intensive Care Unit and Intermediate Medical Care Unit
Background: The implementation of clinical information systems (CISs) alone and with hospital electric medical records in intensive care units (ICUs) can lead to numerous errors. This study aimed to investigate errors in an ICU and intermediate medical care unit (IMU) for 9 months after implementing of a CIS.Methods: A CIS was incrementally implemented in the general ICU and IMU of a university hospital over 3 months and was used for all patients by April 2019. The errors encountered over 9 months were extracted from the hospital's incident reporting system.Results: Overall, 122 and 140 errors in the ICU and IMU, respectively, during the study period. Incidence rates of the errors in the ICU and IMU were 31.7 (95% confidence interval [CI] 26.3-37.8) and 51.3 (43.2-60.6) events per 1,000 patient-days, respectively. There were 17 (14%) and 15 (11%) CIS-related errors in the ICU and IMU, respectively. The incidence rates of errors in the ICU and IMU were 5.3 (3.1-8.5) and 6.5 (3.6-10.7) events per 1,000 CIS operation patient-days, respectively.Conclusions: Thirteen percent of the errors in the ICU and IMU were related to the CIS, and the incidence did not vary with the staffing intensity of both care units.The study was registered at the University Hospital Medical Information Network Clinical Trials Registry (UMIN000039402)
Differential responses of normal human coronary artery endothelial cells against multiple cytokines comparatively assessed by gene expression profiles
AbstractEndothelial cells play an important role in terms of biological functions by responding to a variety of stimuli in the blood. However, little is known about the molecular mechanism involved in rendering the variety in the cellular response. To investigate the variety of the cellular responses against exogenous stimuli at the gene expression level, we attempted to describe the cellular responses with comprehensive gene expression profiles, dissect them into multiple response patterns, and characterize the response patterns according to the information accumulated so far on the genes included in the patterns. We comparatively analyzed in parallel the gene expression profiles obtained with DNA microarrays from normal human coronary artery endothelial cells (HCAECs) stimulated with multiple cytokines, interleukin-1β, tumor necrosis factor-α, interferon-β, interferon-γ, and oncostatin M, which are profoundly involved in various functional responses of endothelial cells. These analyses revealed that the cellular responses of HCAECs against these cytokines included at least 15 response patterns specific to a single cytokine or common to multiple cytokines. Moreover, we statistically extracted genes contained within the individual response patterns and characterized the response patterns with the genes referring to the previously accumulated findings including the biological process defined by the Gene Ontology Consortium (GO). Out of the 15 response patterns in which at least one gene was successfully extracted through the statistical approach, 11 response patterns were differentially characterized by representing the number of genes contained in individual criteria of the biological process in the GO only. The approach to dissect cellular responses into response patterns and to characterize the pattern at the gene expression level may contribute to the gaining of insight for untangling the diversity of cellular functions
Human A-myb gene encodes a transcriptional activator containing the negative regulatory domains
AbstractThe myb gene family has three members, c-myb, A-myb, and B-myb. A-myb mRNA is mainly expressed in testis and peripheral blood leukocytes. A-Myb can activate transcription from the promoter containing Myb-binding sites in all cells examined. In addition to the two domains (a DNA-binding domain and a transcriptional activation domain), two negative regulatory domains have been identified in A-Myb. These results indicate that A-Myb functions as a transcriptional activator mainly in testis and peripheral blood cells, and the regulatory mechanism of A-Myb activity is similar to that of c-Myb
Influence of genetic factors on the ephedrine alkaloid composition ratio of Ephedra plants
We investigated the ephedrine alkaloid [(-)-ephedrine and (+)-pseudoephedrine] composition ratio of a crude Chinese herbal drug described in the Japanese Pharmacopoeia \u27Ephedra herb (Chinese name: Mahuang)\u27. There were marked changes in the alkaloid composition ratio of wild plants in areas where both male and female clusters coexisted. However, in genetically homogeneous areas with the growth of male or female clusters alone, all of the coefficients of the regression lines were positive, but each gradient varied. This suggests that the alkaloid composition ratio has a clear tendency in each individual. Based on this, we cultivated individuals for vegetative propagation, and evaluated the alkaloid content ratio. Those propagated by separating the roots showed a specific tendency regardless of the cultivation area (Wakayama, Tanegashima). Those propagated by separating the herbaceous stem showed a specific tendency regardless of the soil or harvest time. In addition, we surveyed the (-)-ephedrine content ratio of 3- to 6-year-old strains. There was a high positive correlation coefficient between the previous and subsequent years. These findings suggest that the ephedrine alkaloid composition ratio of Ephedra herb depends on genetic factors, but not on environmental factors or the growth period
Foot-Bathing Therapy Improved Sleeplessness in a Mechanically Ventilated Patient: A Case Report
A practical device for pinpoint delivery of molecules into multiple neurons in culture
We have developed a device for pinpoint delivery of chemicals, proteins, and nucleic acids into cultured cells. The principle underlying the technique is the flow of molecules from the culture medium into cells through a rupture in the plasma membrane made by a needle puncture. DNA transfection is achieved by stabbing the needle tip into the nucleus. The CellBee device can be attached to any inverted microscope, and molecular delivery can be coupled with conventional live cell imaging. Because the position of the needle relative to the targeted cultured cells is computer-controlled, efficient delivery of molecules such as rhodamine into as many as 100 HeLa cells can be completed in 10 min. Moreover, specific target cells within a single dish can be transfected with multiple DNA constructs by simple changes of culture medium containing different plasmids. In addition, the nano-sized needle tip enables gentle molecular delivery, minimizing cell damage. This method permits DNA transfection into specific hippocampal neurons without disturbing neuronal circuitry established in culture
