Factors influencing the quality of life over a 4-year period of time in Romanian patients with diabetes mellitus.

AIM: To evaluate the changes in quality of life (QOL), diabetic neuropathy (DN) and amputations over 4 years in patients with diabetes. METHODS: In 2012, 25,000 Romanian-translated Norfolk QOL-DN self-administered questionnaires were distributed during a cross-sectional study. Between March-December 2016, all patients identified from the 2012 cohort and enrolled in this follow-up study completed the Norfolk QOL-DN questionnaire; amputations suffered since 2012 were recorded. The influence of age and duration of diabetes (DD) on delta QOL scores (defined as the differences between 2012 and 2016 scores) and of sex, age, diabetes type, DD and declared DN on amputations was explored using multivariate linear and logistic regression, respectively. RESULTS: The mean (standard deviation) age of the 1865 participants was 60.6 (10.3) years. Mean total QOL-DN score increased from 2012 to 2016 by 4.39% (P = .079). Both DD (b = 0.39, 95% confidence interval [CI] 0.21-0.57, P < .001) and age (b = 0.25, 95% CI 0.13-0.36, P < .001) were significantly correlated with total QOL-DN score. Delta total QOL was higher in patients whose statement about having DN changed since 2012. Over 4 years, 36 patients suffered amputations. Male sex (OR = 3.11, 95% CI 1.46-6.62, P = .003), physical functioning/large-fibre neuropathy subscale score (OR = 1.04, 95% CI 1.001-1.09, P = .047), autonomic neuropathy subscale score (OR = 0.78, 95% CI 0.64-0.94, P = .011) and small-fibre neuropathy subscale score (OR = 1.21, 95% CI 1.05-1.40, P = .007) were significant predictors of amputations. Delta total QOL-DN score was 10 times higher in patients who suffered amputation(s) compared with their amputation-free counterparts. CONCLUSION: QOL deteriorates with age and DD. Norfolk QOL-DN subscale scores can predict amputations.

Lipidomics biomarkers in women with polycystic ovary syndrome (PCOS) using ultra-high performance liquid chromatography-quadrupole time of flight electrospray in a positive ionization mode mass spectrometry.

Polycystic ovary syndrome (PCOS), characterized by oligo-anovulation and androgen excess is considered a high-risk condition for metabolic disorders. Herein, untargeted metabolomics analysis was applied to women with PCOS, aiming to provide deeper insights into lipidomics biomarkers signature of PCOS, for better diagnosis and management. This was a cross-sectional study in which 15 Caucasian women with PCOS and 15 Caucasian healthy, age-matched women were enrolled. Lipidomics analysis was performed using Ultra-High Performance Liquid Chromatography-Quadrupole Time of Flight Electrospray Mass Spectrometry. Partial Least Squares Discriminant Analysis retrieved the most important discriminative metabolites. Significantly increased levels of triacylglycerol (18:2/18:2/0-18:0) in addition to cholestane-3beta, 5alpha, 6beta-triol (18:0/0:0) and cholestane-5alpha (18:1/0:0) appeared as valuable variables to differentiate subjects with PCOS from controls. Acyl-carnitine 2-hydroxylauroylcarnitine was significantly elevated in PCOS in opposition to decreased phosphocholines metabolites (18:1/18:4, 18:3/18:2), to suggest a metabolic pattern linked to lipid peroxidation. A high fat intake or reduced fat energy consumption during nighttime due to diminished ability to switch to lipid oxidation during fasting time possibly contribute to hypertriglyceridemia found in PCOS. Furthermore, inflammatory mediators including metabolites of the prostaglandin (PG) E2 pathway and oxo-leukotrienes (LT) were increased in patients with PCOS. Potential lipidomics biomarkers were identified that could stratify between women with PCOS and healthy controls. The results show particular alterations in acylglycerols, PGs and LTs and phosphocholines and carnitine metabolites. The lipidomics profiles of PCOS indicate a higher risk of developing metabolic diseases.

Chronic disruption of circadian rhythm with mistimed sleep and appetite - an exploratory research.

This research aimed to explore the relation of social jetlag (SJL) with perceived appetite, and hormones involved in hunger regulation in healthy subjects in free-living conditions (study registration number: ACTRN12618001182280). Eighty normally diurnally active men and women were enrolled in 4 study groups according to the presence of SJL and sleep deprivation (2 groups with SJL with or without sleep deprivations and 2 groups without SJL with or without sleep deprivation) matched 1:1:1:1 for age, gender, and body mass index. Appetite was assessed in fasting state, by measuring acylated ghrelin level and using 100 mm visual analog scales. Persons with SJL had a higher perceived appetite for pork, poultry, fish, eggs, milk, and dairy products and higher acylated ghrelin levels than those without SJL. When considering the presence of sleep deprivation, subjects with SJL, with and without sleep deprivation, reported a higher perceived appetite than group with sleep deprivation alone. They also reported later meal times for lunch and dinner, had more frequently a snack before sleep and reported eating more frequently while watching TV or playing on computer, suggesting poorer eating habits in these subjects. In conclusion, independent of sleep duration, SJL is associated with an increased appetite for caloric dense food, suggesting an increased incentive value of food in these subjects and an anticipated pleasure of ingesting these foods.

Short-Term Prognosis Value of sST2 for an Unfavorable Outcome in Hypertensive Patients.

BACKGROUND: sST2 represents a useful biomarker for the diagnosis and prognosis of patients with heart failure, but limited data is available on its role in patients with hypertension. The aim of this study is to evaluate the short-term prognosis value of sST2 for an unfavorable outcome in hypertensive patients. METHODS: This was a prospective observational study which enrolled 80 patients with hypertension, who were followed for one year. All patients underwent clinical, laboratory (including sST2), and echocardiographic assessment at baseline. The patients were grouped according to the cardiovascular (CV) events reported during the follow-up: group A (with CV events) and group B (without CV events). RESULTS: Overall, 59 CV events were reported during the follow-up period. Compared to group B, the patients in group A had significantly higher sST2 levels, a higher number of CV risk factors, and a higher left ventricle mass. Except for the diastolic dysfunction parameters, the echocardiographic findings were similar in the two groups. Patients in group A had a lower E/A ratio, larger deceleration time, and increased telediastolic pressure as quantified by the E/E/p = 0.006, Kaplan-Meier analysis). CONCLUSIONS: sST2 levels were correlated with the risk of adverse CV outcomes in hypertensive patients and may represent a useful prognostic marker in these patients.

Social jetlag and sleep deprivation are associated with altered activity in the reward-related brain areas: an exploratory resting-state fMRI study.

OBJECTIVE: The aim of this research was to assess the effect of social jetlag (SJL) and its interaction with partial sleep deprivation on resting-state brain activity using the fractional amplitude of low-frequency fluctuation (fALFF) during free-living conditions. METHODS: A total of 28 normal weight healthy subjects were enrolled in four study groups (with SJL [with sleep deprivation and without sleep deprivation] and without SJL [with sleep deprivation and without sleep deprivation]), matched 1:1:1:1 for age, gender, and body mass index (BMI). Resting-state functional magnetic resonance imaging (fMRI) scans were collected with SIEMENS 3T scanner while subjects were in a fasting state. RESULTS: Participants with SJL had significantly higher fALFF values in right lingual gyrus and right putamen and significantly lower fALFF values in left and right inferior parietal lobe in comparison with participants without SJL and without sleep deprivation. Subjects with sleep deprivation had significantly higher fALFF in the thalamus and left superior frontal gyrus. In those with both SJL and sleep deprivation, we observed higher fALFF values in right Brodmann Area (BA)18 and lower values in left and right parietal inferior lobe. Subjects with SJL alone had significantly lower fALFF values in left frontal mid gyrus (BA6) than those with sleep deprivation alone. CONCLUSIONS: SJL was associated with altered resting-state brain activity in regions that have been shown to be involved in hedonic feeding. The effect of SJL was independent of effects induced by short sleep duration. These alterations might represent the substrate for the increased risk of obesity observed in those with SJL.

Non-alcoholic fatty liver disease, bulb carotid intima-media thickness and obesity phenotypes: results of a prospective observational study.

AIMS: The objective of this prospective study was to assess the correlation between carotid intima-media thickness at the common carotid (CIMTc) and carotid bifurcation (CIMTb) level, hepatic fat accumulation, and obesity phenotypes. MATERIAL AND METHODS: Two hundred obese adults, in which CIMTc and CIMTb thickness was determined, were included. According to body mass index (BMI) and presence of metabolic syndrome (MetS), patients were classified as metabolically healthy obese (MHO, obesity without MetS) and metabolically unhealthy obese (MUHO, obesity with MetS). MHO patients were further classified as MHO1 (obese with increased waist circumference) and MHO2 (obese with increased waist circumference plusone of the 4 criteria for MetS). Non-alcoholic fatty liver disease (NAFLD) presence was assessed by fatty liver index (FLI). RESULTS: CIMTc and CIMTb increased with obesity phenotypes from 0.74 mm and 1.04 mm in MHO1 to 0.84 mm and 1.23 mm in MHO2 and 0.88 mm and 1.74 mm in MUHO. Obesity phenotypes were significantly correlated with CIMTb. NAFLD frequency increased from 66.0% in the MHO1 to 73.0% in the MHO2 and 84.2% in the MUHO (p<0.05). Independent of age, BMI, total cholesterol, HbA1c, and HOMA-IR, the CIMTc was significantly associated with FLI in all obesity phenotypesand CIMTb only in MHO2 and MUHO. CONCLUSIONS: Our results suggest that subclinical atherosclerosis varies according to obesity phenotypes and is correlated with the hepatic fat accumulation.
