Utility of Lean Body Mass Equations and Body Mass Index for Predicting Outcomes in Critically Ill Adults with Sepsis: A Retrospective Study.

Lean body mass is a significant component of survival from sepsis. Several equations can be used for calculating lean body mass based on age, sex, body weight, and height. We hypothesized that lean body mass is a better predictor of outcomes than the body mass index (BMI). This study used a multicenter cohort study database. The inclusion criteria were age ≥18 years and a diagnosis of sepsis or septic shock. BMI was classified into four categories: underweight (<18.5 kg/m2), normal (≥18.5-<25 kg/m2), overweight (≥25-<30 kg/m2), and obese (≥30 kg/m2). Four lean body mass equations were used and categorized on the basis of quartiles. The outcome was in-hospital mortality among different BMI and lean body mass groups. Among 85,558 patients, 3916 with sepsis were included in the analysis. Regarding BMI, in-hospital mortality was 36.9%, 29.8%, 26.7%, and 27.9% in patients who were underweight, normal weight, overweight, and obese, respectively (p < 0.01). High lean body mass did not show decreased mortality in all four equations. In critically ill patients with sepsis, BMI was a better predictor of in-hospital mortality than the lean body mass equation at intensive care unit (ICU) admission. To precisely predict in-hospital mortality, ICU-specific lean body mass equations are needed.

Association of Hypnotic Drug Use with Fall Incidents in Hospitalized Elderly Patients: A Case-Crossover Study.

We investigated whether use of hypnotic drugs, including benzodiazepine receptor agonists, as well as ramelteon and suvorexant are associated with fall incidents in elderly inpatients aged no less than 75 years, who were hospitalized at an acute care general hospital in Japan, between November 1st, 2016 and October 31st, 2017. Multivariate analysis results were reported as odds ratio (OR) with 95% confidence interval (CI). Following to a case-crossover study protocol, the time windows of the case and the control days were assigned to the day or the days, which are one day or 2-8 d before the fall incidents, respectively. In the enrolled 111 patients, the accumulated total available numbers of the cases and the control days were 111 and 554 patient days, respectively. Hypnotic drug use was significantly associated with fall incidents (OR: 2.85, 95% CI: 1.03-7.90, p = 0.04). Especially benzodiazepine receptor agonists (OR: 5.79, 95% CI: 1.52-22.1, p = 0.01) showed statistically significant association with fall incidents. In contrast, neither ramelteon (OR: 7.95, 95% CI: 0.72-87.9, p = 0.09) nor suvorexant (OR: 0.25, 95% CI: 0.06-1.06, p = 0.06) were significantly associated with fall incidents. Thus, benzodiazepine receptor agonists, but not ramelteon or suvorexant, showed significant association with fall incidents. Therefore, special care should be taken especially when benzodiazepine receptor agonists are administrated to elderly subjects. In contrast, fall risk may be much less in patients treated with ramelteon or suvorexant. These results could help us to conduct safer drug treatment for insomnia patients aged no less than 75 years.

Reduced Serum Cholesterol and Triglyceride Levels in a Choline-Deficient L-Amino Acid-Defined High-Fat Diet (CDAHFD)-Induced Mouse Model of Non-alcoholic Steatohepatitis (NASH).

Non-alcoholic fatty liver disease (NAFLD) or non-alcoholic seatohepatitis (NASH) is one of the major health problems world wide, because of increased abdominal obesity. To date, specific and effective medications to treat or prevent NAFLD/NASH have not been established. To identify appropriate molecular targets for that purpose, suitable animal models of NAFLD/NASH have been explored. A choline-deficient amino acid-defined high fat diet (CDAHFD)-induced mouse model of NASH has been developed. However, its relevance to human NASH, including serum lipid profiles, have not been clearly defined. In this study, we have revealed that mice fed CDAHFD showed significantly lowerd serum total cholesterol and triglyceride (TG) levels, in addition to reduced body weight (BW). Furthermore, hepatic microsomal triglyceride transfer protein (MTP) expression was significantly downregulated in CDAHFD-fed mice. Thus, the current CDAHFD-fed mouse model has points that are distinct from human NAFLD/NASH, in general, which is based upon abdominal obesity.

Effects of Ramelteon and Other Sleep-Promoting Drugs on Serum Low-Density Lipoprotein and Non-high-density Lipoprotein Cholesterol: A Retrospective Comparative Pilot Study.

Melatonin has been suggested to play important roles in lipid metabolism as well as circadian rhythm; however, very few studies explored the effects of ramelteon, a selective melatonin receptor agonist, on serum lipid profiles. In this study effects of ramelteon on serum lipid profiles were explored, comparing to those of other sleep-promoting drugs including benzodiazepines and non-benzodiazepines, in patients with insomnia. We retrospectively reviewed medical charts of outpatients who were treated with ramelteon (8 mg/d) or other sleep-promoting drugs for no less than 8 weeks during the period between October 1st, 2011 and September 30th, 2014, and compared the changes in serum lipid profiles between the two groups. Patients with regular dialysis or malignant diseases treated with cytotoxic anti-cancer drugs, or whose lipid-lowering drugs were altered during the study period, were excluded. Among 365 or 855 outpatients treated with ramelteon or other sleep-promoting drugs, 35 or 46 patients, respectively, had complete serum low-density lipoprotein cholesterol (LDL-C) or non-high-density lipoprotein cholesterol (non-HDL-C) data. Serum LDL-C was significantly reduced from 103.1±4.4 to 94.6±4.2 mg/dL (8.2% reduction, p<0.05, n=31) in the ramelteon group, and was not significantly changed (p=0.23, n=40) in the other sleep-promoting drug group. Non-HDL-C was significantly decreased from 138.8±6.0 to 130.6±4.9 mg/dL (5.9% reduction, p<0.05, n=32) in the ramelteon group, and was not significantly altered (p=0.29, n=42) in the other sleep-promoting drug group. Ramelteon, but not other sleep-promoting drugs, specifically lowers serum LDL-C and non-HDL-C levels.

Comparison of serum lipid management between elderly and non-elderly patients with and without coronary heart disease (CHD).

Serum lipid management in patients aged ≥ 75 has not been precisely explored. We, therefore, compared the serum lipid management between the two age groups with and without coronary heart disease (CHD). We, therefore, retrospectively reviewed medical charts of patients who were hospitalized in the departments of internal medicine during a period of 14 months. Serum lipid goal attainment was explored by applying the lipid goals for patients aged < 75 to those aged ≥ 75. In 1988 enrolled patients, 717 subjects (36.1%) were aged ≥ 75. Among them, 41.3% and 32.4% of the patients had CHD, 44.2% and 41.0% were primary prevention at high-risk, and 14.5% and 14.6% were primary prevention at moderate-risk in patients aged ≥ 75 and aged < 75, respectively. Serum LDL-C goal achievement rates in CHD were 66.9% and 65.0% in patients aged ≥ 75 and < 75, respectively (p = 0.334). In the primary prevention at high-risk, these rates were 73.5% and 63.3%, in patients aged ≥ 75 and < 75, respectively (p = 0.001). They were 77.9% and 58.1% in primary prevention at moderate-risk aged ≥ 75 and < 75, respectively (p < 0.001). In CHD, lipid-lowering medication subscription rates were significantly lower in patients aged ≥ 75 (60.1%) than those aged < 75 (73.8%, p < 0.001). In conclusion, in CHD, serum lipid goal attainment was comparable between the two age groups although the lipid-lowering drugs were less frequently prescribed in patients aged ≥ 75. Without CHD, it was significantly better in patients aged ≥ 75 than those aged < 75 although the lipid-lowering drug subscription rates were comparable between the two age groups.

Serum Lipid Goal Attainment in Chronic Kidney Disease (CKD) Patients under the Japan Atherosclerosis Society (JAS) 2012 Guidelines.

AIM: According to the Japan Atherosclerosis Society 2012 guidelines (JAS2012-GL), chronic kidney disease (CKD) has newly been added to the high-risk group in terms of atherosclerotic cardiovascular diseases. We therefore explored the lipid target level achievement rates under the JAS2012-GL in real-world clinical practice. METHODS: We retrospectively reviewed the medical charts of patients who were hospitalized at the Nephrology Department at Kobe City Medical Center General Hospital in the period from April 1, 2012 to May 31, 2013 and explored the serum lipid target level achievement rates. Patients without lipid data or those undergoing regular dialysis because of chronic renal failure were excluded. In this study, the CKD group (CKD-G) did not include CKD patients under secondary prevention for coronary heart disease (CHD) or diabetes mellitus (DM). RESULTS: The CKD-G included 146 (81.1%) of the 180 enrolled patients. According to the JAS2012-GL, 100% of the CKD-G patients were categorized into the high-risk group, although only 12.1% of the CKD-G subjects were at high risk according to the JAS2007-GL. Under the JAS2012-GL, the LDL cholesterol (LDL-C) and non-HDL cholesterol (non-HDL-C) target level achievement rates for CKD-G were 71.4% and 68.1%, respectively. According to the JAS2007-GL, these rates were 81.3% and 79.1%, respectively, and, under both guidelines, these rates were 71.7% and 72.1% for primary prevention DM and 66.7% and 66.7% for CHD, respectively. CONCLUSIONS: After the revision of the JAS-GL in 2012, the LDL-C and non-HDL-C target level achievement rates for CKD-G were reduced by approximately 10%; however, they remained similar to those for DM and higher than those for CHD.

A combination of molecular probe-tandem electrospray ionization mass spectrometry: a technique for tracing structural changes in phospholipid hydroperoxides.

An ethyl-labeled phosphatidylcholine hydroperoxide (PC-OOH/Et 2) was synthesized as a molecular probe for naturally occurring PC-OOH 1. Applying the precursor ion scan mode in tandem ESI mass spectrometry at m/z 198, a signal of the PC-OOH/Et 2 alone could be selectively detected even in the presence of a large excess of a complex mixture of phospholipids in the blood. Furthermore, molecular species that formed from PC-OOH/Et 2 by its degradation in the blood were also observed in the same spectrum. Since the molecular probe-and-mass spectrometry-assisted analytical method presented herein requires no separation process by HPLC or TLC and is speedy, requiring less than 1 h, it may be useful in lipid analysis.

[Survey of current conditions regarding awareness of the nutritional role of supplements for pharmacy students].

Various nutritional supplements have become available in recent years. However, health problems resulting from the misuse of these supplements are on the rise, and have been attributed to a lack of knowledge among consumers. In addition, a survey of university students revealed that approximately 20% of students erroneously considered nutritionally balanced supplements as substitutes for meals. Given this background, we conducted a questionnaire survey of first- and fourth-year students at the Faculty of Pharmaceutical Sciences at Kobe Gakuin University with the objective of elucidating factors such as the awareness of supplements among pharmacy students and whether these students had a superior understanding of supplements compared to the general student population. Awareness of supplements among students was determined in terms of the degrees of emphasis on meals and supplements in nutritional intake. The proportion of students who essentially believed that "nutritionally balanced supplements can be used as substitutes for meals" did not significantly differ between pharmacy students and the general student population. In addition, only 30% of students had an accurate understanding of supplements. Following graduation, pharmacy students may become pharmacists and thus be responsible for providing directions regarding usage of supplements. These findings suggest that in order to nurture professional pharmacists, it is necessary to first implement practical nutrition education and consumer education to promote healthier dietary habits among the students themselves.
