Two months after discontinuation of HRT, all women increased FMD (11.7 ± 6 vs. 7.2 ± 4%) and reduced PWV (7.8 ± 1.7 vs. 9.1 ± 2.4 m/s) and cSBP (123 ± 14 vs. 130 ± 15 mmHg). There were no statistically significant changes in BMI, cIMT and GLS (P > 0.05 for all comparisons). The percentage decrease of cSBP was associated with the percentage decrease of PWV (r = 0.54) and reversely related with the percentage increase of FMD (r = -0.57; P < 0.05 for all comparisons).

HFpEF is a prevalent clinical syndrome with increased cardiovascular morbidity and mortality. Specific guideline-directed medical therapy (GDMT) for HFpEF is not established due to lack of positive outcome data from randomized controlled trials (RCTs) and limitations of available studies. Although available evidence is limited, control of blood pressure (BP) is widely regarded as central to the prevention and clinical care in HFpEF. Thus, in current guidelines including the 2018 European Society of Cardiology (ESC) and European Society of Hypertension (ESH) Guidelines, blockade of the renin-angiotensin system (RAS) with either angiotensin-converting enzyme inhibitors or angiotensin receptor blockers provides the backbone of BP-lowering therapy in hypertensive patients. Although superiority of RAS blockers has not been clearly shown in dedicated RCTs designed for HFpEF, we propose that this core drug treatment strategy is also applicable for hypertensive patients with HFpEF with the addition of some modifications. The latter apply to the use of spironolactone apart from the treatment of resistant hypertension and the use of the angiotensin receptor neprilysin inhibitor. In addition, novel agents such as sodium-glucose co-transporter-2 inhibitors, currently already indicated for high-risk patients with diabetes to reduce heart failure hospitalizations, and finerenone represent promising therapies and results from ongoing RCTs are eagerly awaited. The development of an effective and practical classification of HFpEF phenotypes and GDMT through dedicated high-quality RCTs are major unmet needs in hypertension research and calls for action.
Previous research has shown an association between moderate workload exercise blood pressure (BP) and coronary disease, whereas maximal exercise BP is associated with stroke. We aimed to investigate the association between the increase in BP during maximal exercise and the long-term risk of stroke in healthy, middle-aged men.

Two thousand and fourteen men were included in the Oslo Ischemia Study in the 1970s. selleck chemicals In the present study, we examined baseline data of the 1392 participants who remained healthy and performed bicycle exercise tests both at baseline and 7 years later. Cox proportional hazard was used to assess the risk of stroke in participants divided into quartiles based on the difference between resting and maximal workload SBP (ΔSBP) at baseline, adjusting for resting BP, age, smoking, serum cholesterol and physical fitness. Follow-up was until the first ischemic or hemorrhagic stroke through 35 years.

There were 195 incident strokes; 174 (89%) were ischemic. In univariate analyses, there were significant positive correlations between age, resting SBP, resting DBP and SBP at moderate and maximal workload, and risk of stroke. In the multivariate analysis, there was a 2.6-fold (P < 0.0001) increase in risk of stroke in ΔSBP quartile 4 (ΔSBP > 99 mmHg) compared with ΔSBP quartile 2 (ΔSBP 73-85 mmHg), which had the lowest risk of stroke. ΔSBP quartile 1 had a 1.7-fold (P = 0.02) increased risk compared with quartile 2, suggesting a J-shaped association to stroke risk.

Stroke risk increased with increasing difference between resting and maximal exercise SBP, independent of BP at rest, suggesting that an exaggerated BP response to physical exercise may be an independent predictor of stroke.

This systematic review and meta-analysis was designed to determine the overall mean blood pressure and prevalence of hypertension among a representative sample of adults living with cerebral palsy by combining individual participant data. Additional objectives included estimating variations between subgroups and investigating potential risk factors for hypertension.

Potential datasets were identified by literature searches for studies published between January 2000 and November 2017 and by experts in the field. Samples of adults with cerebral palsy (n ≥ 10, age ≥ 18 years) were included if blood pressure data, cerebral palsy-related factors (e.g. cerebral palsy subtype), and sociodemographic variables (e.g. age, sex) were available. Hypertension was defined as at least 140/90 mmHg and/or use of antihypertensive medication.

We included data from 11 international cohorts representing 444 adults with cerebral palsy [median (IQR) age of the sample was 29.0 (23.0-38.0); 51% men; 89% spastic type; Gross Motor Function Classification System levels I-V]. Overall mean SBP was 124.9 mmHg [95% confidence interval (CI) 121.7-128.1] and overall mean DBP was 79.9 mmHg (95% CI 77.2-82.5). Overall prevalence of hypertension was 28.7% (95% CI 18.8-39.8%). Subgroup analysis indicated higher blood pressure levels or higher prevalence of hypertension in adults with cerebral palsy above 40 years of age, men, those with spastic cerebral palsy or those who lived in Africa. BMI, resting heart rate and alcohol consumption were risk factors that were associated with blood pressure or hypertension.

Our findings underscore the importance of clinical screening for blood pressure in individuals with cerebral palsy beginning in young adulthood.

Low-molecular-weight heparins (LMWHs) are the most commonly used anticoagulants in neonates. Published guidelines delineate dosing and monitoring protocols for LMWH therapy in newborns. However, challenging clinical situations frequently present that warrant healthcare providers to think critically beyond the range of guidelines, and judiciously resolve specific problems. This review describes the use of LMWH in the neonatal population, including practical aspects such as route and site of administration, preparation from concentrated formulations and methods to minimize pain of subcutaneous injection. It is followed by a discussion on dosing, monitoring and outcomes of LMWH therapy in neonates. The risk of recurrence of thrombosis in neonates after LMWH therapy is approximately 3% based on a pooled analysis of studies reporting this outcome over the last 24 years. The article concludes with an overview of the side-effects of LMWH, including the risk of bleeding which is around 4% based on pooled analyses of more than 30 studies.Adult chronic idiopathic thrombocytopenic purpura (cITP) is a chronic and usually life-long haemorrhagic disorder in which enhanced platelet destruction and weakened platelet production lead to thrombocytopenia. Platelets were isolated from blood samples collected from 40 adult patients with cITP and 40 healthy volunteers. Mitochondrial membrane potential (ΔΨm) and plasma membrane phosphatidylserine externalization were determined by flow cytometry, and activation of caspase-3 and expressions of Bax, Bak and Bcl-xL were analysed by western blotting. Flow cytometry showed increased mitochondrial depolarization and lower ΔΨm in platelets from adult patients with cITP. In addition, plasma membrane phosphatidylserine externalization was observed on platelets from adult patients with cITP, but rarely from healthy volunteers. Western blot analysis of platelet proteins revealed that, in adult cITP patients, caspase-3 was activated, which cleaved gelsolin and to release a 47-kDa fragment. Moreover, the expressions of Bax and Bak were elevated, and Bcl-xL was decreased markedly in platelets from adult patients with cITP. Our findings reveal, based on loss of mitochondrial membrane potential (Δψm), phosphatidylserine exposure, caspase-3 activation, enhanced expression of Bax and Bak, and attenuated expression of Bcl-xL, that platelet death in the pathogenesis of thrombocytopenia in chronic ITP in adults is apoptotic.To explore the causative mutation for autosomal recessive inheritance factor V (FV) deficiency in a Chinese family. Relative coagulation indexes and the FV antigen were tested by the one-stage clotting method and ELISA, respectively. At the same time, the calibrated automated thrombogram (CAT) was used to analyze the mutant protein function. All 25 exons, flanking sequences, 5' and 3' untranslated regions of the F5 were amplified by PCR and sequenced directly, while each suspected variant was verified by reverse sequencing. The possible impact of the mutant was analyzed by the corresponding bioinformatics software. The phenotypic tests showed that the proband's FV activity has decreased to 24%, whereas the FV antigen has also reduced to 28%. The genetic analysis revealed that she was a compound heterozygote for a frameshift variant from small deletion in the exon 13 (c.2390_2390delC, p.Pro798Leufs*13) and a missense mutation in the exon 25 (c.6665A>G, p.Asp2222Gly). Meanwhile, the online bioinformatics software indicated that the frameshift variant was disease-causing. The pathogenic variant p.Pro798Leufs*13 and the benign variant p.Asp2222Gly largely account for the decrease of the FV deficiency in this Chinese family, of which the pathogenic variant is firstly reported in the world.Congenital factor XIII (FXIII) deficiency is one of the rarest bleeding disorders, with an incidence of one per 2 million persons. Intracranial hemorrhage (ICH), a major cause of mortality in FXIII deficiency, is reported to be associated with vascular endothelial growth factor (VEGF) and thrombospondin-1 (TSP-1). Therefore, we investigated the association of VEGF and TSP-1 expression and methylation patterns with ICH in congenital FXIII deficiency patients. This study was conducted on 40 participants with FXIII, 20 of whom experienced ICH (cases), and 20 who did not (controls). Methylation pattern, gene expression, and plasma protein level were assessed using bisulfite sequencing PCR, quantitative real-time PCR, and ELISA. We found a partially methylated pattern for both VEGF and TSP-1 (P > 0.05). VEGF mRNA levels of the case group were significantly higher than those of the control group (P  0.05). Our findings showed no obvious correlation between VEGF or TSP-1 methylation patterns and expression, suggesting that their expression in FXIII deficiency may not solely be controlled by gene methylation.
