About the need to use specific population references in estimating paediatric hypertension: Sardinian blood pressure standards (age 11-14 years)

<p>Abstract</p> <p>Background</p> <p>Previous Italian paediatric blood pressure (BP) tables overestimated the prevalence of hypertension in adolescents of specific geographic areas, such as Sardinia, an island in the Mediterranean Sea. This is probably due to a not very homogeneous distribution of the subjects studied, most from Middle and Northern Italy, and the long period from the survey.</p> <p>Methods</p> <p>BPs were repeatedly measured over a period of 3 years in 839 children (52.6% males. Age range: from 11 to 14 years during this period), using a standard mercury sphygmomanometer. For each gender, the specific percentile curves of systolic and diastolic BP were constructed.</p> <p>Results (corrected by the 50^thpercentile of height)</p> <p>Males (11-14 years)</p> <p>mean systolic BP (50^thcentile): from 111 to 115 mmHg. Hypertensive systolic BP (> 95^thpercentile): from 127 to 135 mmHg. Mean diastolic BP (50^thcentile): from 65 to 69 mmHg. Hypertensive diastolic BP (> 95^thpercentile): from 78 to 82 mmHg.</p> <p>Females(11-14 years)</p> <p>mean systolic BP (50^thcentile): from 110 to 112 mmHg. Hypertensive systolic BP (> 95^thpercentile): from 127 to 130 mmHg. Mean diastolic BP (50^thcentile): from 65 to 67. Hypertensive diastolic BP (> 95^thpercentile): from 78 to 80 mmHg.</p> <p>Conclusions</p> <p>Sardinian BP tables emphasizes the need to integrate the previous standards with more up-to-date and representative reports on Italian children, as periodically performed in the USA, in order to increase the number of subjects to be checked, and to obtain a national coverage better and more completely representative of every geographic area of our country.</p

The Jurisprudential Niche Occupied by Law and Economics

This paper describes the jurisprudential niche occupied by the several schools of thought that comprise the field of Law and Economics in present-day legal scholarship. It begins by providing a brief history of law in the U.S.; it highlights the void left in law by the Legal Realists; it then very briefly explores some of the theories that attempted to fill that void including critical legal studies, feminist jurisprudence, and critical race theory. The paper then turns to its main focus - describing the several schools of thought that comprise the field of Law and Economics that has also helped fill the void. These include the Chicago approach to law and economics, public choice theory, institutional law and economics, the new institutional economics, social norms and law and economics, the New Haven school, and Austrian law and economics

Trimetazidine improves left ventricular function in diabetic patients with coronary artery disease: a double-blind placebo-controlled study

BACKGROUND: Patients with diabetic cardiomyopathy have an impaired myocardial glucose handling and distal distribution of coronary atherosclerosis. Trimetazidine, an anti-ischemic metabolic agent, improves myocardial glucose utilization though inhibition of fatty acid oxidation. Aim of the present study was to evaluate whether the metabolic effect of trimetazidine on left ventricular function in patients with diabetic cardiomyopathy. METHODS: 32 patients (24 males and 8 females, mean (SE) age = 67 ± 6 years) with type 2 diabetes and ischemic cardiomyopathy were randomized to receive either trimetazidine (20 mg, t.d.s.) or placebo (t.d.s.) for six months in a randomized parallel study. Patients performed an echocardiogram at baseline and after 6 months. RESULTS: Demographic data were comparable between the two groups. After six month baseline left ventricular end-diastolic diameters increased from 62.4 ± 1.7 to 63 ± 2.1 mm in the placebo group, while decreased from 63.2 ± 2.1 to 58 ± 1.6 mm (p < 0.01 compared to baseline) in the trimetazidine group. Compared to baseline, left ventricular ejection fraction increased by 5.4 ± 0.5% (p < 0.05) in the trimetazidine group while remained unchanged in the placebo group -2.4 ± 1.1% (NS), p < 0.01 between groups. A significant improvement in wall motion score index and in the E/A wave ratio was detected in patients treated with trimetazidine, but not in those receiving placebo. CONCLUSION: in diabetic patients with ischemic heart disease trimetazidine added to standard medical therapy has beneficial effect on left ventricular volumes and on left ventricular ejection fraction compared to placebo. This effect may be related to the effect of trimetazidine upon cardiac glucose utilization

Delafloxacin: Place in Therapy and Review of Microbiologic, Clinical and Pharmacologic Properties

Delafloxacin (formerly WQ-3034, ABT492, RX-3341) is a novel fluoroquinolone chemically distinct from currently marketed fluoroquinolones with the absence of a protonatable substituent conferring a weakly acidic character to the molecule. This property results in increased intracellular penetration and enhanced bactericidal activity under acidic conditions that characterize the infectious milieu at a number of sites. The enhanced potency and penetration in low pH environments contrast what has been observed for other zwitterionic fluoroquinolones, which tend to lose antibacterial potency under acidic conditions, and may be particularly advantageous against methicillin-resistant Staphylococcus aureus, for which the significance of the intracellular mode of survival is increasingly being recognized. Delafloxacin is also unique in its balanced target enzyme inhibition, a property that likely explains the very low frequencies of spontaneous mutations in vitro. Delafloxacin recently received US Food and Drug Administration approval for the treatment of acute bacterial skin and skin structure infections and is currently being evaluated in a phase 3 trial among patients with community-acquired pneumonia. In the current era of a heightened awareness pertaining to collateral ecologic damage, safety issues and antimicrobial stewardship principles, it is critical to describe the unique properties of delafloxacin and define its potential role in therapy. The purpose of this article is to review available data pertaining to delafloxacin\u27s biochemistry, pharmacokinetic/pharmacodynamics characteristics, in vitro activity and potential for resistance selection as well as current progress in clinical trials to ultimately assist clinicians in selecting patients who will benefit most from the distinctive properties of this agent

Communication and shared decision-making after stillbirth: Results of the ShaDeS study

Background: Shared decision-making (SDM) is included in guidelines for bereavement care after a stillbirth, as it can improve women’s long-term health and wellbeing. SDM within the stillbirth context is still not common, and Italy does not yet have standardised guidelines. Aim: The ShaDeS (Shared Decision-Making in Stillbirth) study aims to investigate how Italian women with a stillbirth perceive their own centrality in decision-making processes around bereavement care and how this might impact satisfaction of care. Methods: The ShaDeS study is a cross-sectional study based on a web survey consisted of four sections: socio- demographic information and medical history, communication of bad news and bereavement care, decisions about childbirth (SDM-Q-9, SHARED, and DCS), and decisions and communication about autopsy (CPS). Findings: 187 women answered the survey. For the 41.1% of women that did not have an emergency childbirth, the SDM-Q-9 median score was 66.6 (0–100 range), and the SHARED median score was 3.5 (1–5 range). 29.4% of participants reached the proposed cutoff of 37.5 in the DCS (0–100 range) suggesting a difficulty in reaching decisions. Satisfaction scores were lower for those with such difficulties (p &lt; 0.0001). Of the 64.5% of women that discussed autopsy, 28.3% were involved in an SDM approach, despite this being associated with higher levels of satisfaction of care (p &lt; 0.05). Conclusion: An SDM approach is only moderately widespread amongst our participants, despite it being signif- icantly related to higher levels of satisfaction. Further studies should investigate the tools that both patients and healthcare professionals need for an SDM approach

Metabolomic Profiles on Antiblastic Cardiotoxicity: New Perspectives for Early Diagnosis and Cardioprotection

Antiblastic drugs-induced cardiomyopathy remains a relevant cause of morbidity and mortality, during and after chemotherapy, despite the progression in protective therapy against cardiovascular diseases and myocardial function. In the last few decades, many groups of researchers have focused their attention on studying the metabolic profile, first in animals, and, subsequently, in humans, looking for profiles which could be able to predict drug-induced cardiotoxicity and cardiovascular damage. In clinical practice, patients identified as being at risk of developing cardiotoxicity undergo a close follow-up and more tailored therapies. Injury to the heart can be a consequence of both new targeted therapies, such as tyrosine kinase inhibitors, and conventional chemotherapeutic agents, such as anthracyclines. This review aims to describe all of the studies carried on this topic of growing interest

Early impairment of contractility reserve in patients with insulin resistance in comparison with healthy subjects

Background: Insulin resistance (IR) is currently considered a crucial cardiovascular (CV) risk factor, which seems to play a dominant role in the evolution toward cardiac and vascular impairment. Early IR-induced cardiac dysfunction can be assessed by Doppler-derived myocardial systolic strain rate (SR) index, measured at baseline and after dobutamine stress echocardiography (DSE).Methods: Thirty IR patients (HOMA-IR = 7 ± 5.2, age 52.6 ± 2.1 years), and 20 healthy, age and sex matched controls were studied. IR had been diagnosed in all patients in the 3 months preceding the study. Dobutamine echocardiography was performed in all subjects to exclude ischemic heart disease, and left ventricular contractile reserve (LVCR) was then assessed. LVCR was evaluated as an increase in the peak of an average longitudinal SR, measured in the basal and mid segments of 2 and 4 chamber ventricular walls.Results: No significant differences between the 2 groups were revealed by baseline echocardiography. In contrast, after DSE a significant decrease of Delta SR was found in the IR group in comparison to the controls (0.54 ± 0.31 s-1vs 1.14 ± 0.45 s-1; p < 0.0001).Conclusions: Our results show that IR, even if isolated and arising within a short time period, not only represents the initial phase of future diabetes, but may adversely affect heart function, as evidenced by the depressed LVCR. Our data strengthen the need for attention to be paid to IR state and for an early therapeutic approach

Metabolic effect of telmisartan and losartan in hypertensive patients with metabolic syndrome

BACKGROUND: Metabolic syndrome is a cluster of common cardiovascular risk factors that includes hypertension and insulin resistance. Hypertension and diabetes mellitus are frequent comorbidities and, like metabolic syndrome, increase the risk of cardiovascular events. Telmisartan, an antihypertensive agent with evidence of partial peroxisome proliferator-activated receptor activity-gamma (PPARγ) activity, may improve insulin sensitivity and lipid profile in patients with metabolic syndrome. METHODS: In a double-blind, parallel-group, randomized study, patients with World Health Organization criteria for metabolic syndrome received once-daily doses of telmisartan (80 mg, n = 20) or losartan (50 mg, n = 20) for 3 months. At baseline and end of treatment, fasting and postprandial plasma glucose, insulin sensitivity, glycosylated haemoglobin (HBA(1c)) and 24-hour mean systolic and diastolic blood pressures were determined. RESULTS: Telmisartan, but not losartan, significantly (p < 0.05) reduced free plasma glucose, free plasma insulin, homeostasis model assessment of insulin resistance and HbA(ic). Following treatment, plasma glucose and insulin were reduced during the oral glucose tolerance test by telmisartan, but not by losartan. Telmisartan also significantly reduced 24-hour mean systolic blood pressure (p < 0.05) and diastolic blood pressure (p < 0.05) compared with losartan. CONCLUSION: As well as providing superior 24-hour blood pressure control, telmisartan, unlike losartan, displayed insulin-sensitizing activity, which may be explained by its partial PPARγ activity

Prepare your indicators: Economics imperialism on the shores of law and development

This article explores the influence of economics on the demand for, and deployment of, indicators in the context of the World Bank's investment climate campaign. This campaign is characterised by an emphasis on marketisation, mathematisation and quantification, which are respectively the normative, analytical and empirical approaches of choice in mainstream economics. The article concludes that economics generally, and indicators in particular, have brought a certain discipline and energy to the field of law and development. But this ‘progress’ has often been at the expense of non-economic values and interests, and even of our ability to mourn their loss
