Abstract
(1) Background: The tolerance of preterm newborns for the high nutritional intakes given by parenteral nutrition (PN) is still debated because of the risk of metabolic complications. Despite enteral nutrition (EN) being the preferred route of nutrition, an exclusive enteral feeding is not always possible, as in preterm newborns, the gut is immature and less tolerant of EN. We aimed to study the impact of a minimal enteral feeding (MEF) on the possible early metabolic complications of PN in a cohort of preterms with gestational age at birth GA ≤ 29 + 6/7 weeks of postmenstrual age. (2) Methods: We divided the study sample in two cohorts: 1) Late-Feeding (cohort 1), newborns who received MEF starting from the 8th day of age, and (2) Early-Feeding (cohort 2), newborns who received MEF, consisting of the administration of at least 4-5 mL/kg/day by the enteral route, in the first 7 days of age. The primary outcome of the study was the rate of at least one metabolic complication, including hyperglycemia, hypertriglyceridemia, or metabolic acidosis. (3) Results: We enrolled 80 newborns (Late-Feeding cohort 51 vs. Early-Feeding cohort 29). The rate of all metabolic complications was statistically higher in the Late-Feeding cohort compared to the Early-Feeding cohort. Binary logistic regression analysis showed that late administration of MEF negatively influenced the rate of all metabolic complications. (4) Conclusions: Early minimal administration of EN is associated with less frequent PN-related metabolic side effects and a higher rate of survival in critically ill newborns.

Abstract
PURPOSE To investigate the metabolic impact of currently used therapies in polycystic ovary syndrome (PCOS). METHODS This is an observational, retrospective and transversal protocol. A small cohort of 133 patients, aged 14-48 years, diagnosed with PCOS was divided into four experimental groups: 1) untreated PCOS patients (n = 51); 2) PCOS patients treated with one of the following therapies (n = 82): a) combined oral contraceptives (COC, n = 35); b) metformin (n = 11); and c) inositols (n = 36). RESULTS Although only < 10% of patients included in this cohort can be strictly encompassed in the development of metabolic syndrome, approximately 20% had insulin resistance. In PCOS patients, COC treatment modified the hormonal profile and worsened lipid parameters (increasing cholesterol and triglyceride levels) and insulin resistance, whereas inositol therapies improved significantly insulin resistance and glycosylated hemoglobin, reducing cholesterol and triglyceride levels. In these women, obesity was associated with greater alterations in lipid and glycemic metabolism and with higher blood pressure levels. PCOS patients with phenotype A presented vaster alterations in lipid metabolism and higher values of glycosylated hemoglobin as well as blood pressure compared to other PCOS phenotypes. CONCLUSIONS Results in this paper suggest that inositol therapies (alone or combined with COC) are the most useful therapies with the best benefits against PCOS symptoms. Thus, integrative treatment may become a more efficient long-term choice to control PCOS symptoms. Furthermore, obesity can be considered as an adverse symptom and calorie restriction a key element of combined treatment in PCOS, not only for fertility management but also in long-term metabolic sequelae.

Abstract
High overall nutritional quality (NQ) is an important component of ideal cardiovascular health, a concept introduced in 2010 by the American Heart Association. However, data on the independent contribution of overall NQ to the variation in the cardiometabolic risk (CMR) profile are limited. This observational study aimed to investigate the association between overall NQ and the CMR profile in 4785 participants (65⋅4 % of men, age 43⋅3 (sd 10⋅8) years) who underwent a cardiometabolic health evaluation, including lifestyle habits, anthropometric measurements, blood pressure, lipid profile and HbA1c concentrations. In addition, a submaximal exercise test was conducted to assess cardiorespiratory fitness (CRF). Using a standardised NQ questionnaire (twenty-five items food-based questionnaire), participants were classified into three subgroups: (1) low, (2) moderate or (3) high NQ and variance and multiple linear regression analyses were performed. Results showed that less than 15 % of participants presented a high NQ. A high NQ was associated with a healthier lifestyle habits and a more favourable CMR profile (lower values of waist circumference and cholesterol:HDL-cholesterol ratio, lower concentrations of non-HDL-cholesterol, TAG and HbA1c). Some of these associations were independent of age, physical activity level (PAL) and CRF. A better NQ was also associated with a lower proportion of participants presenting the hypertriacylglycerolaemic waist phenotype independently of both PAL and CRF. The present study suggests that overall NQ can be assessed with a short food-based questionnaire and should be considered in clinical practice as a new 'vital sign' associated with other health behaviours and cardiometabolic health.

Abstract
OBJECTIVES In the general population, metabolic health often declines as BMI increases. However, some obese individuals maintain metabolic health. HIV and antiretroviral therapy have been associated with metabolic disturbances. We hypothesized that HIV-infected (HIV) men on suppressive antiretroviral therapy experience less metabolic health than HIV-uninfected (HIV) men across all BMI categories. DESIGN/METHODS In a cross-sectional analysis of 1018 HIV and 1092 HIV men enrolled in the multicenter AIDS cohort study, Poisson regression with robust variance determined associations between HIV serostatus and metabolic health prevalence (defined as meeting ≤2 of 5 National Cholesterol Education Program Adult Treatment Panel III metabolic syndrome criteria), adjusting for age, race, BMI category, smoking, and hepatitis C virus infection status. RESULTS HIV men were younger (54 vs. 59 years) and had lower median BMI (25 vs. 27 kg/m). Nonobese HIV men had lower metabolic health prevalence than HIV men (BMI ≤25 kg/m: 80 vs. 94%, P < 0.001; BMI 25-29 kg/m: 64 vs. 71%, P = 0.05), but metabolic health prevalence among obese men did not differ by HIV serostatus (BMI 30-34 kg/m: 35 vs. 39%, P = 0.48; BMI ≥35 kg/m: 27 vs. 25%, P = 0.79). In the adjusted model, nonobese HIV men were less likely to demonstrate metabolic health than nonobese HIV men. Among HIV men, per year darunavir, zidovudine, and stavudine use were associated with lower metabolic health likelihood. CONCLUSION Metabolically healthy obesity prevalence does not differ by HIV serostatus. However, among nonobese men, HIV infection is associated with lower metabolic health prevalence, with associations between lack of metabolic health and darunavir and thymidine analog nucleoside reverse transcriptase inhibitor exposure observed.

Abstract
OBJECTIVE To evaluate whether pregnancy-associated hypertension (gestational hypertension and preeclampsia) was associated with the cardiometabolic health of young offspring. METHODS This was a prospective observational follow-up study from 2012 to 2013 of children born to women previously enrolled in a mild gestational diabetes mellitus treatment trial or nongestational diabetes mellitus observational study. At 5-10 years after birth, children were examined and fasting blood samples obtained to determine the following cardiometabolic risk factors: blood pressure (BP), high-density lipoprotein cholesterol, triglycerides, glucose, homeostatic model assessment of insulin resistance, waist circumference, and body mass index (BMI). RESULTS This analysis included 979 children evaluated at a median 7 years of age. Twenty-three (2%) were born preterm from a hypertensive pregnancy, 73 (7%) were born at term from a hypertensive pregnancy, 58 (6%) were born preterm from a normotensive pregnancy, and 825 (84%) were born at term from a normotensive pregnancy (reference group). After adjusting for confounding factors, mean adjusted systolic BP was significantly higher in the children who were born at term to mothers who experienced pregnancy-associated hypertension compared with those born at term to normotensive mothers (systolic BP of 104 mm Hg, 95% CI 101-106 vs systolic BP of 99 mm Hg, 95% CI 99-100, P=.001). No other significant differences were observed. CONCLUSION Pregnancy-associated hypertension in women who deliver at term was associated with higher systolic BP in the offspring, but not with their measures of diastolic BP, BMI, waist circumference, homeostatic model assessment of insulin resistance, glucose, or lipids.

Abstract
BACKGROUND Obesity induces dyslipidemia, hypertension, glucose intolerance, and inflammatory state, which results in atherogenic processes, diabetes, and cardiovascular disease. We usually use body composition indices, such as body mass index (BMI), body fat percentage (BFP), waist circumference-height ratio (WHtR), and waist-hip ratio (WHR) to reflect the obesity. The aim of this large population-based cross-sectional study was to investigate the associations between body composition indices and metabolic parameters in Chinese adults. METHODS A total of 12,018 Chinese adults were included. Body composition indices, such as BMI, BFP, WHtR, and WHR, and metabolic parameters, such as systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglyceride (TG), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), fasting blood glucose (FBG), 2 h postprandial blood glucose (2h PBG), glycosylated hemoglobin (HbA1c), fasting insulin (FINS), insulin resistance index (HOMA-IR), high-sensitivity C-reactive protein (hs-CRP), and white blood cell count (WBC), were measured and analyzed. All analyses were stratified by gender. RESULTS All body composition indices and metabolic parameters except 2h PBG differed significantly between males and females (all P < 0.001). BMI was positively associated with SBP, DBP, LDL-C, TC, TG, FBG, 2h PBG, HbA1c, FINS, HOMA-IR, hs-CRP, and WBC, and inversely associated with HDL-C; similar relationships were identified between the metabolic parameters and BFP, WHtR, and WHR. In the multivariate analysis, the odds of impaired glucose regulation, dyslipidemia, insulin resistance, and increased hs-CRP were 1.36, 1.92, 3.44, and 1.27 times greater in the overweight group than those in the normal weight group, respectively, and 1.66, 3.26, 7.53, and 1.70 times greater in the obese group than those in the normal weight group, respectively. The odds of dyslipidemia and hs-CRP were 1.29 and 1.38 times greater in the BFP ≥28.0% group than in the BFP <28.0% group, respectively. The odds of dyslipidemia, HOMA-IR, and hs-CRP were 1.55, 1.26, and 1.48 times greater in the WHtR ≥0.96 group than in the WHtR <0.96 group, respectively. Among males, the odds of HOMA-IR were 1.46 times greater in the WHR ≥0.54 group than in the WHR <0.54 group. Similar results were observed in females. CONCLUSIONS This study identified positive associations between all evaluated body composition indices and metabolic parameters in Chinese adults. Among the body composition indices, BMI predicted four of the five evaluated metabolic disorders in both gender groups.

Abstract
OBJECTIVES To evaluate the risk and predictors of thiazide-induced adverse events (AEs) in multimorbid older adults in real-world clinical settings. DESIGN Observational cohort study. SETTING National Veterans Affairs data from 2007 to 2008. PARTICIPANTS Veterans aged 65 and older newly prescribed a thiazide (N = 1,060) compared with propensity-matched nonusers of antihypertensive medications (N = 1,060). MEASUREMENTS The primary outcome was a composite of metabolic AEs defined as sodium less than 135 mEq/L, potassium less than 3.5 mEq/L, or a decrease in the estimated glomerular filtration rate (eGFR) of more than 25% from the baseline rate. Secondary outcomes included sev-ere AEs (sodium <130 mEq/L, potassium <3.0 mEq/L, or a decrease in eGFR of more than 50%). RESULTS Over 9 months of follow-up, 14.3% of new thiazide users developed an AE, compared with 6.0% of nonusers (number needed to harm (NNH) 12, 95% confidence interval (CI) = 9-17, P < .001); 1.8% of new users developed a severe AE, compared with 0.6% of nonusers (NNH = 82, P = .008), and 3.8% of new users had an emergency department visit or hospitalization with an AE, compared with 2.0% of nonusers (NNH = 56, P = .02). Risk of AEs did not vary according to age, but having five or more comorbidities was associated with 3.0 times the odds (95% CI = 1.4-6.2) of developing an AE as having one comorbidity (hypertension). Low-normal and unmeasured baseline sodium and potassium values were among the strongest predictors of hyponatremia and hypokalemia, respectively. Only 42% of thiazide users had laboratory monitoring within 90 days after initiation. CONCLUSION Thiazide-induced AEs are common in older adults. Greater attention should be paid to potential complications in prescribing thiazides to older adults, including closer laboratory monitoring before and after initiation of thiazides.

Abstract
CONTEXT PTH is a critical factor in mineral homeostasis, and chronic kidney disease mineral and bone metabolism disorder is a very important problem in patients with renal failure. Abnormal levels of PTH, serum phosphate, and calcium influence chronic kidney disease mineral and bone metabolism disorder, but there is little information about the influence of magnesium (Mg) on PTH. OBJECTIVE The aim of this study was to elucidate the correlation between magnesium and PTH levels in uremic patients just prior to beginning hemodialysis (HD) for the first time. PATIENTS We enrolled 1231 patients in nine Japanese facilities who had begun HD for end-stage renal disease. We investigated their serum Mg levels and the correlation between intact PTH (iPTH) and the serum Mg levels and other clinical parameters and medications. RESULTS The mean serum Mg was 2.2 ± 0.5 mg/dL, and hypermagnesemia was found in 663 patients (53.9%). Divided into two groups according to median iPTH level, the serum Mg levels were significantly higher in patients with low iPTH (2.3 ± 0.5 vs 2.1 ± 0.5, P < .01). Furthermore, divided into two groups according to the Mg level, iPTH levels were lower in patients with high Mg than in patients with normal serum Mg levels (277.9 ± 195.9 pg/mL vs 321.9 ± 203.7 pg/mL, P < .01). In the multiple regression analysis according to the effect of iPTH level, the serum Mg level was an independent variable after adjustment for other factors. CONCLUSIONS A high serum level of Mg is frequent in uremic patients with end-stage renal disease just prior to beginning HD. In the present set of patients, there was a significant correlation between the serum Mg and iPTH levels. Furthermore, the serum Mg level was an independent factor apart from the other factors regulating iPTH. These results suggest that serum Mg may be one of the factors regulating the serum PTH level in uremic patients.
