Abstract
OBJECTIVES Solid-organ transplant recipients have high rates of invasive fungal infections. Candida species are the most commonly isolated fungi. Our aim was to identify risk factors, clinical presentations, and outcomes of candidemia in solid-organ transplant recipients. MATERIALS AND METHODS We evaluated adult (≥18 years old) transplant recipients seen from May 2011 to December 2022 at Baskent University Ankara Hospital. From medical records, we retrospectively reviewed age, sex, transplant type, candidemia agent, risk factors, concomitant infections, and mortality of patients with Candida detected in blood culture. We used SPSS statistics software (version 25) to analyze data. RESULTS There were 1080 organ transplants performed during the study period (717 kidney, 279 liver, 84 heart). There were 855 who were ≥18 years (655 kidney, 127 liver, 73 heart), of whom candidemia was detected in 26 (16 male; 11 kidney, 11 liver, 4 heart) with a median age of 47.5 years. The most common agents were Candida albicans and Candida glabrata. The most common chronic diseases were hypertension, cirrhosis, and cardiomyopathy. Eighteen patients had a concomitant focus of infection. Ten patients had pneumonia accompanying candidemia. The 30-day mortality rate was as high as 53.8%. The mean duration of candidemia after transplant was 23 months. Catheter-related candidemia was observed in 65% of patients. The 30-day mortality was found to be significantly higher in patients followed in the intensive care unit (P = .014), receiving total parenteral nutrition (P = .001), using broad-spectrum antibiotics (P = .001), and having pneumonia (P = .042) accompanying candidemia. CONCLUSIONS For adult solid-organ transplant recipients with candidemia, careful monitoring is essential for successful management of total parenteral nutrition, central catheter, use of broadspectrum antibiotics, and invasive interventions.

[PMID: 38107136 PMCID: PMC10724638 DOI: 10.1002/fsn3.3722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 09/18/2023] [Accepted: 09/20/2023] [Indexed: 12/19/2023] Open
Abstract
Phase angle and vitamin D can reflect the state of the body cells, and the two may interact with each other. Therefore, this study was conducted to find out the relationship between PA and vitamin D. Taking women in early pregnancy as our study subjects, we found that PA had a positive effect on vitamin D levels. Body composition phase angle, as a noninvasive, easy-to-operate, and easy-to-monitor indicator, can be used an early screening index for vitamin D nutrition levels in early pregnancy, and the cutoff value was 4.95°.

Sleep Med X 2022; 4:100056. [PMID: 36274862 PMCID: PMC9579360 DOI: 10.1016/j.sleepx.2022.100056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2021] [Revised: 02/21/2022] [Accepted: 08/28/2022] [Indexed: 11/29/2022] Open
Abstract
Objective To investigate the relation between serum 25-hydroxyvitamin D (s-25(OH)D) and subjective sleep measures in an Arctic population (69°N). Methods Cross-sectional data was collected from 21,083 individuals (aged ≥40 years) participating in the population based Tromsø Study: Tromsø7 (2015–2016). The present study included 20,438 participants, after having excluded respondents missing data on s-25(OH)D (n = 161) and/or subjective sleep measures (including sleep duration, insomnia, and daytime sleepiness)(n = 490). Based on s-25(OH)D (assessed using LC-MS/MS), participants were grouped as deficient (<30 nmol/L), insufficient (30–49.9 nmol/L), sufficient (50–75 nmol/L), or high (>75 nmol/L). Sleep duration was grouped as inadequate (ISD) if < 7 or ≥9 h. Linear and logistic regression were used to calculate unstandardized β-values and odds ratios [95% confidence intervals]. The analyses were adjusted for season, age, BMI, lifestyle factors and relevant comorbidities. Results In both men and women, s-25(OH)D was positively associated with sleep duration, and compared to the sufficient s-25(OH)D group, the insufficient s-25(OH)D group reported significantly shorter sleep duration in both sexes. There was an increased odds of ISD in both men and women but adjusted for confounding factors this was only significant in women (1.16 [1.03, 1.32], p = .017). In men, there were no significant associations between s-25(OH)D and the remaining sleep measures. Women in the high s-25(OH)D group had lower ESS-scores (−0.28 [-0.47, −0.08], p = .006), but higher odds of insomnia (1.16 [1.01, 1.33], p = .036) compared to women in the sufficient group. Conclusions In this Arctic population, a tenuous association was found between s-25(OH)D and subjective sleep measures, predominantly in women. 25(OH)D was associated with self-reported sleep measures in this Arctic population. 25(OH)D was positively associated with self-reported sleep duration in both sexes. Women with sufficient 25(OH)D had lower odds of insomnia. RCTs are needed to determine the role of vitamin D in sleep health.

Association of accelerometer-measured physical activity with kidney function in a Japanese population: the DOSANCO Health Study. BMC Nephrol 2022; 23:7. [PMID: 34979979 PMCID: PMC8722077 DOI: 10.1186/s12882-021-02635-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Accepted: 12/09/2021] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Sedentary behavior and decreased physical activity are associated with reduced kidney function, yet most evidence is based on self-reported physical activity. This study investigated the association between accelerometer-based physical activity level and kidney function in a general Japanese population. METHODS A cross-sectional study was conducted in 440 community-dwelling Japanese participants, aged 35-79 years. Time (min/d) was assessed for the following types of physical activity: sedentary behavior, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA). Kidney function was assessed using estimated glomerular filtration rate (eGFR). A linear regression model was employed to calculate the β coefficient of eGFR for a 60-min/d increase in sedentary behavior and LPA and a 10-min/d increase in MVPA. A logistic regression model was used to calculate the odds ratio for low eGFR (< 60 versus ≥60 mL/min/1.73m2) for a 60-min/d or 10-min/d increase in each physical activity type. RESULTS MVPA time and eGFR were positively associated in both men and women, after adjusting for age, body mass index, and other clinical characteristics (Men: β, 0.91; P = 0.021; Women: β, 0.70; P = 0.034). In women, sedentary behavior and eGFR were inversely associated after adjusting for the same factors (β, - 1.06; P = 0.048). The odds ratio (95% confidence interval) for low eGFR associated with a 60-min increase in sedentary behavior was 1.65 (1.07-2.55) after adjusting for the same factors in women. CONCLUSION Longer sedentary behavior and shorter MVPA time were associated with lower kidney function in the Japanese population.

Abstract
Background Vitamin D has been linked to sleep health in observational studies. Data from randomized controlled trials (RCTs) with vitamin D is scarce. Methods This study presents the results of a secondary analysis of 189 vitamin D insufficient participants (47.1% women) in a previously performed RCT, of which 92 were randomized to vitamin D (100,000 IU (2500 μg) as a bolus dose followed by 20,000 IU (500 μg) per week), and 97 to placebo. At baseline and after 4 months at the end of the study serum 25-hydroxyvitamin D (s-25(OH)D) was measured, and the study questionnaire assessing sleep duration, daytime sleepiness, and symptoms of insomnia, was completed. Results At baseline, mean s-25(OH)D was 35.0 ± 11.8 and 35.5 ± 13.3 nmol/L in the vitamin D and placebo groups, respectively. After four months, we found no statistically significant differences between the intervention groups in any of the assessed sleep outcomes, neither when stratified by sex, nor when performed in subgroups based on baseline or end of study s-25(OH)D level or presence of sleep complaints at baseline. Conclusions We were not able to demonstrate a significant effect of vitamin D supplementation on sleep in this vitamin D insufficient population. RCT investigating vitamin D for 4 months in participants with low vitamin D status. Vitamin D did not improve sleep duration, excessive daytime sleepiness or insomnia. The role of vitamin D in sleep health remains controversial.

Abstract
BACKGROUND Previous research has established that women accumulate less moderate-to-vigorous physical activity (MVPA) than men. To date, however, little is known about the gender differences in device-based activity patterns of sedentary behavior (SB) and light-intensity physical activity (LPA). We aimed to compare time spent in SB and different intensities of physical activity taking into account of co-dependence of time use domains. METHODS This cross-sectional study was conducted in Suttu town, Hokkaido, Japan. Data were analyzed from 634 Japanese adults (278 men, aged 19-92 years) who provided valid accelerometer (HJA-750C) data. Gender differences in activity behavior patterns were tested using multivariate analysis of covariance (MANCOVA) based on isometric log-ratio transformations of time use, adjusting for age. We also developed bootstrap percentile confidence intervals (CI) to support the interpretation of which behavior differed between genders. RESULTS Overall, participants had percent time spent in SB, LPA, MVPA during wearing time (mean, 14.8 hours) corresponding to 53.9%, 41.7%, and 4.4% of wearing time, respectively. Activity behavior patterns differed significantly between genders after controlling for time spent in all activities. Women spent relatively 13.3% (95% CI, 9.9-15.9%) less time in SB and 19.8% (95% CI, 14.9-24.6%) more time in LPA compared to men. The difference of time spent in MVPA was not statistically significant. CONCLUSIONS In contrast with previous studies, our findings suggest that Japanese women are more physically active than men when all intensities of activities are considered. Given the health benefits of LPA, evaluating only MVPA may disproportionately underestimate the level of physical activity of women.

Abstract
Serum fatty acids (FAs) exist in the four lipid fractions of triglycerides (TGs), phospholipids (PLs), cholesteryl esters (CEs) and free fatty acids (FFAs). Total fatty acids (TFAs) indicate the sum of FAs in them. In this study, four statistical analysis methods, which are independent component analysis (ICA), factor analysis, common principal component analysis (CPCA) and principal component analysis (PCA), were conducted to uncover food sources of FAs among the four lipid fractions (CE, FFA, and TG + PL). Among the methods, ICA provided the most suggestive results. To distinguish the animal fat intake from endogenous fatty acids, FFA variables in ICA and factor analysis were studied. ICA provided more distinct suggestions of FA food sources (endogenous, plant oil intake, animal fat intake, and fish oil intake) than factor analysis. Moreover, ICA was discovered as a new approach to distinguish animal FAs from endogenous FAs, which will have an impact on epidemiological studies. In addition, the correlation coefficients between a published dataset of food FA compositions and the loading values obtained in the present ICA study suggested specific foods as serum FA sources. In conclusion, we found that ICA is a useful tool to uncover food sources of serum FAs.

Abstract
In Western populations, fecal concentrations of short-chain fatty acids (SCFAs) are positively correlated with the prevalence of obesity. However, gut microbiota involved in the production of SCFA varies between races. Our purpose was to investigate the associations between fecal SCFAs and the prevalence of obesity in a community-based Japanese population. We classified a total of 568 participants aged ≥18 into four quartiles of fecal concentrations of SCFA subtypes (acetate, butyrate, and propionate) and total SCFAs to compare the prevalence of obesity, defined as a body mass index ≥ 25.0 kg/m2. Using the first quartile SCFA group as a reference, the prevalence ratios of obesity were calculated for each SCFA group through a log-binomial regression model adjusted for major potentially confounding factors including age, sex, exercise habits, total energy intake, and total dietary fiber intake. In the study population, the prevalence of obesity was 35.8%. The prevalence ratios (95% confidence intervals) of obesity in the second, third, and fourth quartile groups of fecal total SCFAs were 1.30 (0.89-1.89), 1.74 (1.23-2.47) and 1.70 (1.19-2.41), respectively, after adjusting for the confounders. Similar positive associations were observed for every subtype. The prevalence ratios (95% confidence intervals) in the fourth quartile groups of fecal acetate, butyrate, and propionate were 1.41 (1.02-1.97), 2.16 (1.49-3.14), and 1.97 (1.35-2.89), respectively, after adjusting for the confounders. In conclusion, our results demonstrated that fecal SCFA concentrations of every subtype were positively associated with the prevalence of obesity in a community-based Japanese population.

Abstract
BACKGROUND We developed and compared two liquid chromatography methods, one with UV/Visible spectrophotometric detection (HPLC) and the other with mass spectrometric detection (LC-MS), for quantifying very-long chain fatty acids (VLCFA) in human plasma. Association of VLCFA with various cardiovascular risk factors were evaluated. METHOD Fasting blood samples were collected from 541 human volunteers (242 men and 299 women; mean age ±SD, 58.9 ± 12.4 years), including 429 and 112 individuals with and without hypertriglyceridemia, respectively. Esterified VLCFA were saponified and derivatized with 2-nitrophenylhydrazine. Separation of VLCFA species was achieved with C4 Mightysil column (HPLC) and Ascentis Express Phenyl-Hexyl column (LC-MS) followed by spectrophotometric and selected-reaction monitoring mode of mass spectrometric detection, respectively. RESULTS The HPLC assay of VLCFA was precise with intra-assay imprecision of 2.5% to 6.9% and inter-assay imprecision of 3.2% to 9.5%. Moreover, there was an excellent correlation (r > 0.96) between HPLC and LC-MS methods. The 95 percentile reference intervals (RI; upper limit) of VLCFA were determined to be 41.3 µmol/L in healthy volunteers. Plasma VLCFA were significantly correlated with triglycerides (Spearman's ρ = 0.306, P < 0.001) and total cholesterol (Spearman's ρ = 0.251, P < 0.001). All species of VLCFA were significantly elevated in hypertriglyceridaemic individuals compared with control. CONCLUSION We established LC-based assays of VLCFA with either spectrophotometry or mass spectrometry as a detection system. Hypertriglyceridaemia is significantly associated with elevated concentration of each species of VLCFA.

Effects of vitamin D on mood and sleep in the healthy population: Interpretations from the serotonergic pathway. Sleep Med Rev 2020; 55:101379. [PMID: 32987320 DOI: 10.1016/j.smrv.2020.101379] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Revised: 06/05/2020] [Accepted: 06/08/2020] [Indexed: 12/18/2022]
Abstract
Vitamin D insufficiency is common in the healthy population. Recent insights addressed the role of vitamin D in serotonin and melatonin regulation, suggesting that increasing vitamin D status may be helpful for improving mood and sleep. This literature review covers the current state of evidence regarding potential effects of vitamin D on mood and sleep indicators in healthy people. In total, 11 observational studies were found for sleep, and 54 studies on mood (including ten RCTs). These studies revealed mixed results for both sleep and mood. The findings were interpreted based on the previously proposed serotonergic pathway of vitamin D. Implications and challenges for future research regarding the timing of blood sampling, timing and dosage of supplement intake and investigating the response dynamics are discussed.

Abstract
Background: The two metabolites of vitamin D; serum 25-hydroxyvitamin D3 (25(OH)D3) and D2 (25(OH)D2), and their independent roles in mood regulation are unexplored. This study aims to examine 25(OH)D3 and 25(OH)D2 and their interplay with depression symptoms.Materials and Methods: Utilizing data from the U.S. National Health and Nutrition Examination Survey (2007-2011, 2013-2014), a cross-sectional study was conducted. Depression was assessed using the 9-item Patient Health Questionnaire, and those with total score ≥5 were considered as having mild to severe depression symptoms. 25(OH)D3 and 25(OH)D2, the clinical markers of vitamins D3 and D2, were measured. Weighted logistic regressions were utilized to examine the adjusted association between 25(OH)D3 and depression, and the effect modification of 25(OH)D2.Results: The sample included 11,471 participants aged 20-80 years. Of those, 23.4% reported symptoms of depression, 28.9% had 25(OH)D3 deficiencies(<20 ng/mL), and 21.5% exhibited presence of 25(OH)D2(>0.6 ng/mL). After adjustment, among participants with presence of 25(OH)D2, those who had 25(OH)D3 deficiencies were more likely by 54% to report depression symptoms (OR = 1.54,95%CI:1.14-2.07). In fact, among participants with nearly no 25(OH)D2 presence, a significant effect estimate between 25(OH)D3 deficiency and depression symptom was not observed(OR = 1.11,95%CI:0.94-1.31).Conclusions: Both vitamin D metabolites retain an independent and significant role in mood regulation. The study provides valuable insights on vitamin D3 and its significant relationship with depression symptoms in the presence of vitamin D2. Further research is required to elucidate the distinct mechanisms of these two vitamin D metabolites on depression.

Abstract
Cholesteryl ester (CE) is an ester of cholesterol and fatty acid (FA). Plasma CE reflects complicated metabolisms of cholesterol, phospholipids, lipoproteins, and dietary FAs. An informatics approach could be useful for analysis of the CE species. In this study, two basic dimension reduction methods, principal component analysis (PCA) and factor analysis, were applied to serum CE species determined by LC-MS/MS in a Japanese population (n = 545). PCA and factor analysis both reflected the size (concentration), food source, fat solubility, and biological aspect of the CE species. In a comparison between PCA (PC4) and factor analysis (factor 4), the latter was found to be more suggestive from a biological aspect of n-6 FAs. Cholesteryl docosahexaenoate (DHA) was found to be unique by a factor analysis, possibly relevant to the unique accumulation of DHA in the brain. An informatics approach, especially factor analysis, might be useful for the analysis of complicated metabolism of CE species in the serum.
