Association of beta-hydroxybutyrate with development of heart failure: Sex differences in a Dutch population cohort.In the failing heart, energy metabolism is shifted towards increased ketone body oxidation. Nevertheless, the association of beta-hydroxybutyrate (β-OHB) with development of heart failure (HF) remains unclear. We investigated the association between plasma β-OHB and the risk of HF in a prospective population-based cohort.

Simultaneous determination of enalapril maleate and nitrendipine in tablets using spectrophotometric methods manipulating ratio spectra.A fixed dose combination of enalapril maleate (EN) and nitrendipine (NT) achieved satisfactory blood pressure control rather than monotherapy. Four accurate spectrophotometric methods utilizing ratio spectra were developed and validated for the simultaneous determination of EN and NT in combined pharmaceutical dosage form (Eneas® tablets). The first method was first derivative ratio spectrophotometric method (DD) where the amplitudes maxima were measured at 219.2 nm and 233.4 nm for the determination of EN and NT, respectively. The second method was ratio difference spectrophotometric method where EN and NT were estimated by measuring the amplitudes difference between 213 nm and 225 nm on the ratio spectrum of EN and between 241 nm and 227 nm on the ratio spectrum of NT. The third method was ratio subtraction followed by extended ratio subtraction, EN was determined at 210 nm by subtraction of the constant values from the ratio spectrum then multiplication with the divisor (NT spectrum). An extended ratio subtraction method was then applied in order to determine NT at 235 nm by using the zero-order spectrum of EN (10 μg/ml) as a divisor. The fourth method was ratio subtraction coupled with constant multiplication methods. The zero- order absorption spectrum of the laboratory prepared mixture was divided by NT (12 μg/ml) spectrum, subsequently, the value of the constant was multiplied by the divisor to obtain the original spectrum of NT, followed by its subtraction from the laboratory prepared mixture to get the spectrum of EN. EN and NT were determined at 210 nm and 235 nm, respectively. Linearity was ascertained over the concentration ranges of (1-11 μg/ml) for EN and (2-14 μg/ml) for NT, for the first and second methods and (2-13 μg/ml) for EN and (3-20 μg/ml) of NT, for the third and fourth methods. Application of the methods to the determination of the cited drugs in Eneas® tablets gave satisfactory results. Methods validation confirmed their accuracy and selectivity. Statistical comparison of the results with the reported one showed no significant difference, regarding precision and accuracy. Routine analysis of the cited drugs in quality control laboratories could be performed using the developed methods.

Effects of ultra-weak fractal electromagnetic signals on the aqueous phase in living systems: a test-case analysis of molecular rejuvenation markers in fibroblasts.Skin aging is primarily associated with the alterations in dermal extracellular matrix, in particular a decrease in collagen type-1 content. Recent studies have shown that collagen-degrading matrix metalloproteinase (MMP-1) is produced by fibroblasts in response to chronoaging, which in human dermal fibroblasts leads to the release of proinflammatory cytokines. Past studies showed that anti-inflammatory capabilities could be induced via non-chemical means. One of these methods makes use of ultra-weak fractal electromagnetic (uwf-EM) signals. Such ultra-/very-low frequency (U/VLF) signals (few nT in intensity and within 0.5-30 kHz) interact with aqueous solutions in living systems. The fractal nature of such EM-signals relates to the self-similar property by which a "cut-out" and magnified piece of this signal reveals again the original. Thus, the aim of this study is twofold, to i) investigate the extent of this modulating effect using Human Dermal Fibroblasts (HDF)-cells, and ii) analyse molecular rejuvenation markers therein. We could demonstrate that a 10 min uwf-EM exposure (prior to incubation) increases type-1 collagen and modulates elastin in human fibroblasts cultured up to 96 h, while at the same time reduces IL-6, TNF-α and MMP-1 (the later three being statistically significant). Such up- respectively down-regulation of corresponding genes are strong indicators of an EM-induced hormetic effect that influences the epigenomic landscape of HDFs. In the Appendix, we present, in the framework of Quantum Field Theory (QFT), water as a biphasic liquid and how its coherent fraction can be affected by uwf-EM signals while at the same time resolving the "kT paradox".

Abortion for Fetal Genetic Abnormalities: Type of Abnormality and Gestational Age at Diagnosis.Advances in genetic screening can identify patients at high risk for common genetic conditions early in pregnancy and can facilitate early diagnosis and early abortion. Less common abnormalities might only be diagnosed with invasive testing is performed after structural abnormalities are identified. Our objective was to compare gestational age (GA) at diagnosis and abortion for genetic abnormalities identified based on screening with abnormalities that were not discovered after screening. All prenatal diagnostic procedures from 2012 to 2017 were reviewed, and singleton pregnancies terminated following diagnosis of genetic abnormalities were identified. Cases diagnosed as the result of screening tests were compared with remaining cases. Conditions were considered "screened for" if they can be suspected by cell-free DNA testing, biochemistry, carrier screening, or if the patient was a known carrier of a single-gene disorder. When abnormal karyotype, microarray, or Noonan's syndrome was associated with abnormal NT, these cases were considered "screened for." GA at abortion was the primary outcome. Fisher's exact test and Mann-Whitney's test were used for statistical comparison. In this study, 268 cases were included. A total of 227 (85%) of abortions were performed for "screened for" disorders, with 210 (93%) of these for karyotype abnormalities, 5 (2%) for microarray abnormalities, and 12 (5%) for single-gene disorders. Forty-one (15%) of abortions were performed for conditions not included in screening, with 8 (19%) of those for karyotype abnormalities, 25 (61%) for microarray abnormalities, and 8 (19%) for single-gene disorders. Invasive testing and abortion occurred at earlier median GA for those with conditions that were screened for: 12 versus 15 weeks, ≤0.001 and 13 versus 20 weeks; ≤0.001. Most abortions were for abnormalities that can be suspected early in pregnancy. As many structural abnormalities associated with rare conditions are not identifiable until the mid-trimester, prenatal diagnosis and abortion occurred significantly later. Physicians and patients should be aware of the limitations of genetic screening.

[Effects of pulse contour cardiac output monitoring technology in amelioration of myocardial damage in fluid resuscitation of patients with large area burn in the early stage].To analyze effects of pulse contour cardiac output (PiCCO) monitoring technology in amelioration of myocardial damage in fluid resuscitation of patients with large area burn in the early stage. From November 2015 to November 2017, medical data of 52 patients with large area burn hospitalized in our unit, meeting the inclusion criteria, were analyzed retrospectively. Twenty-seven patients (18 males and 9 females) with age of (43±10)years in tradition group hospitalized from November 2015 to November 2016 were monitored by traditional monitoring methods for fluid resuscitation, and 25 patients (18 males and 7 females) with age of (44±10)years in PiCCO group hospitalized from December 2016 to November 2017 were monitored by traditional monitoring methods and PiCCO monitoring equipment for fluid resuscitation. Fluid infusion coefficients and total fluid replacement volume of patients in both groups at the first and second post burn hour (PBH) 24, as well as the levels of N terminal pro B type natriuretic peptide (NT-proBNP), cardiac troponin T (cTnT), and creatine kinase MB (CK-MB) immediately on admission and post burn day (PBD) 1, 2, 3, 4, 5, 6, and 7 were recorded. Data were processed with analysis of variance for repeated measurement, chi-square test, test and Bonferroni correction, and Mann-Whitney test and Bonferroni correction. (1) The fluid infusion coefficients of patients in tradition group at the first and second PBH 24 were respectively (1.42±0.10) and (0.94±0.14)mL·kg(-1)·% total body surface area (TBSA)(-1), and those in PiCCO group were respectively (1.76±0.14) and (0.85±0.08) mL·kg(-1)·%TBSA(-1). Fluid infusion coefficient and total fluid replacement volume at the first PBH 24 of patients in PiCCO group were significantly higher than those in tradition group (=-9.775, -4.769, <0.01). Fluid infusion coefficient at the second PBH 24 of patients in PiCCO group was significantly lower than that in tradition group (=2.682, <0.05). There was no statistically significant difference in total fluid replacement volume at the second PBH 24 in patients between the two groups (=1.167, >0.05). (2) Immediately on admission and PBD 1, 2, 3, 4, 5, 6, and 7, the levels of NT-proBNP of patients in tradition group were respectively 518 (320, 763), 236 (98, 250), 139 (62, 231), 172 (104, 185), 296 (225, 341), 727 (642, 921), 1 840 (1 357, 2 081), 1 005 (671, 1 297) pg/mL, and those in PiCCO group were respectively 444 (206, 601), 66 (29, 73), 54(28, 75), 139(101, 175), 199 (106, 279), 576 (333, 837), 833 (466, 1 080), 485 (225, 710) pg/mL. The levels of NT-proBNP of patients in PiCCO group on PBD 1, 2, 6, and 7 were significantly lower than those in tradition group (=-5.004, -3.967, -5.285, -4.626, <0.01). The levels of NT-proBNP immediately on admission and PBD 3, 4, and 5 in patients between the two groups were close (=-0.834, -0.806, -2.665, -2.153, >0.05). (3) Immediately on admission and PBD 1, 2, 3, 4, 5, 6, and 7, the levels of cTnT of patients in tradition group were respectively (42±15), (21±12), (17±7), (11±4), (12±4), (94±32), (88±23), (42±23) pg/L, and those in PiCCO group were respectively (37±15), (9±3), (10±3), (13±3), (12±5), (85±30), (60±26), (22±14) pg/L. The levels of cTnT of patients in PiCCO group on PBD 1, 2, 6, and 7 were significantly lower than those in tradition group (=5.227, 4.751, 4.239, 3.845, <0.01). The levels of cTnT immediately on admission and PBD 3, 4, and 5 of patients between the two groups were close (=1.098, -1.562, -0.117, 1.107, >0.05). (4) The levels of CK-MB of patients in PiCCO group on PBD 3, 6, and 7 were significantly lower than those in tradition group (=3.123, 4.103, 3.178, <0.05 or <0.01). The levels of CK-MB immediately on admission and PBD 1, 2, 4, and 5 in patients between the two groups were close (=0.351, 1.868, 1.100, 0.798, 2.094, >0.05). PiCCO monitoring technology can monitor and guide fluid resuscitation of patients with large area burn in the early stage more scientifically and reasonably, and the effect of reducing myocardial damage is better than traditional monitoring methods.
