The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.

2007 Guidelines for the Management of Arterial Hypertension : The Task Force for the Management of Arterial Hypertension of the European Society of Hypertension (ESH) and of the European Society of Cardiology (ESC).

Because of new evidence on several diagnostic and therapeutic aspects of hypertension, the present guidelines differ in many respects from the previous ones. Some of the most important differences are listed below: 
1. Epidemiological data on hypertension and BP control in Europe. 
2. Strengthening of the prognostic value of home blood pressure monitoring (HBPM) and of its role for diagnosis and management of hypertension, next to ambulatory blood pressure monitoring (ABPM). 
3. Update of the prognostic significance of night-time BP, white-coat hypertension and masked hypertension. 
4. Re-emphasis on integration of BP, cardiovascular (CV) risk factors, asymptomatic organ damage (OD) and clinical complications for total CV risk assessment. 
5. Update of the prognostic significance of asymptomatic OD, including heart, blood vessels, kidney, eye and brain. 
6. Reconsideration of the risk of overweight and target body mass index (BMI) in hypertension. 
7. Hypertension in young people. 
8. Initiation of antihypertensive treatment. More evidence-based criteria and no drug treatment of high normal BP. 
9. Target BP for treatment. More evidence-based criteria and unified target systolic blood pressure (SBP) (<140 mmHg) in both higher and lower CV risk patients. 
10. Liberal approach to initial monotherapy, without any all-ranking purpose. 
11. Revised schema for priorital two-drug combinations. 
12. New therapeutic algorithms for achieving target BP. 
13. Extended section on therapeutic strategies in special conditions. 
14. Revised recommendations on treatment of hypertension in the elderly. 
15. Drug treatment of octogenarians. 
16. Special attention to resistant hypertension and new treatment approaches. 
17. Increased attention to OD-guided therapy. 
18. New approaches to chronic management of hypertensive disease

A method to determine an optimal temperature profile that guarantees products having controlled molecular weight distribution (MWD) and desired values of molecular weight (Mw) is presented. The base case is the batch polymerization of MethylMethAcrylate, initiated by AIBN. On the basis of the kinetic model, the optimal temperature profile is determined by imposing that the value of the instantaneous chain length is maintained constant, thus counteracting the effects of the increase of viscosity, which leads to broad MWD. Some approximations permit to express, in a straightforward way, the relationship between the optimal temperature and the conversion as a function of the initial conditions. The validity of the simplifying hypotheses that have been assumed is confirmed first by simulation results and then by a comparison with experimental runs conducted in a labscale unit, with determination of MWD made by means of GPC. The obtained results suggest that it is possible to decouple the problem: acting on the operating temperature to control the MWD, acting on initial temperature and initiator concentration to influence the Mw. The possibility of application to industrial reactors has also been investigated, taking into account their peculiarities and constraints. © 1995 John Wiley & Sons, Inc.

Optimal temperature for the control of the product quality in batch polymerization: Simulation and experimental results

Seventeen essential hypertensive patients with normal renal function were treated with a new non-sulphydryl orally active angiotensin converting enzyme (ACE) inhibitor, benazepril, 10 mg given once or twice daily, according to diastolic blood pressure levels, for 6 weeks. In all patients, changes in blood pressure, systemic and renal hemodynamics, plasma renin activity and urinary aldosterone and albumin excretions were assessed at the end of a 2-week placebo run-in period and at the end of the study. Benazepril monotherapy controlled blood pressure well. No changes in cardiac output, heart rate or stroke volume were observed, while peripheral vascular resistance was significantly decreased (-11%, P less than 0.05). Plasma volume was unaltered. The glomerular filtration rate was stable, but effective renal plasma flow was increased because of the marked reduction in renal vascular resistance (-35%) and, therefore, the filtration fraction was decreased. Urinary albumin excretion remained unchanged. A significant increase in plasma renin activity (P less than 0.001) and a decrease in urinary aldosterone excretion were seen. No side effects were observed during the treatment period. In conclusion, our results suggest that benazepril alone is an effective antihypertensive agent in patients with essential hypertension. The blood pressure lowering effect is due mainly to systemic vasodilation and is observed up to 24 h after administration of the drug. The vasodilation appears to be more consistent in the renal than in the systemic circulation.

The current state of the art in the analysis of risk for CO2 transport by pipeline is briefly reviewed, in particular in respect of current models for CO2 release, the assessment of impact from such release, and overall risk analysis. For a simple case study, a comparative analysis is presented of alternative models for the calculation of consequences. This comparison indicates that different assumptions, models and software lead to important differences in the calculation of consequences. Key unresolved problems and some directions for research needed are identified. One of the problems for assessment of the results is the lack of experimental data.

Conceptual Models for CO2 Release and Risk Assessment: a Review

The fallout of ash from Mt Etna has caused significant problems to the resident population, road/rail and air traffic and production activities. This work is focused on the study of the potential damage to industrial structures caused by the fallout of volcanic ash and describes the main objectives of a research project aimed at defining the potentially critical scenarios for industrial installations and infrastructures due to eruptions of Mt. Etna. In the first part of this paper, a description of the method used for the analysis of the potential damage to storage tanks due to ash fallout will be given. The second part will provide the results of the application of the method.

Analysis of the Effects Due to Ash Fallout from Mt. Etna on Industrial Installations

In a study of Nolan and Barton in 1987 it was already underlined that process safety is primarily based on an accurate and detailed knowledge of the thermo-chemistry of the reaction and afterwards on a correct scale up and management. In this work the experimental analysis of hydrogen peroxide decomposition is proposed by the use of a modified pseudo-adiabatic and non differential thermal analysis screening calorimeter. The objective of the work is to study the decomposition of this peroxide and its effects in different operating conditions, particularly when a runaway reaction occurs and may be the cause of incidents leading to fires and explosions and losses of chemicals in general. Runaway reactions have the potential to inflict considerable damage if appropriate emergency measures are not in place. Hydrogen peroxide is liable to decompose exothermically at also at ambient temperature. According to the Major Accident Reporting System (MARS) data bank, in the last 30 years there have been several major accidents involving peroxides and in particular almost 70 % of these accidents were caused by hydrogen peroxide. This is the main reason for which we focused our study on this substance. The Thermal Screening unit (TS) used to carry out the experiments permitted us to find easily useful results such as onset temperature (the temperature at which the decomposition starts), time to maximum rate (the time at which the rate of temperature is maximum) and maximum pressure reached during the reaction. Adding an expansion vessel to the instrument made possible to study the reaction in different initial conditions of pressure (up to 12 bar), and so to evaluate the consequences of it on some critical parameters used to identify runaway reactions. The experimental data obtained by this simple and cost efficient technique have to be validated by experiments run in more complex calorimeters, such as adiabatic and reaction calorimeters, but the use of the TS makes it possible to reduce the number of experiments and to have a first step in risk analysis studies as key in scaling up of processes. An Early Warning Detection System (EWDS) based on divergence criterion is finally applied off-line to the data regarding the decomposition. Both temperature and pressure profiles have been evaluated in order to compare the efficiency of the method to these parameters in terms of advance in detecting the runaway reaction.
