Predictive value of shock index ≥ 1 in severe trauma patients in emergency department.

Background: the shock index (SI) defined by the ratio of systolic blood pressure to heart rate was demonstrated as a simple tool in the triage and orientation of severe trauma patients to trauma centers.

Aim: To assess the prognostic value of the SI ≥ 1 in terms of mortality in severe trauma patients admitted to the emergency room.

Methods: We performed a prospective, observational and descriptive study with the inclusion of severe trauma patients over the age of 18 years admitted to the Vital Emergency Room over a 21-month period.

Drug related adverse events due to cardiotropic agents : Epidemiology and prognosis in the emergency department.

Introduction: The severity of cardiotropic agents overuse is related to the risk of cardiac and hemodynamic life-threatening situations. Toxicity is attributed to their narrow therapeutic spectrum and pharmacodynamic properties. The clinical presentation, however, remains polymorphic and represents a challenge for the emergency physician to relate accountability to the exact agent.

[Epidemiological profiles of diabetic ketoacidosis in the Emergency Department].

Introduction: Diabetic ketoacidosis (DKA) is a severe metabolic complication of diabetes. Recent years have seen a marked increase in prevalence of diabetic ketoacidosis, but mortality is low. This study aimed to describe the epidemiological, clinical, therapeutic and prognostic features of patients with severe or moderate DKA admitted to the Emergency Department.

[Epidemiological and prognostic profile of acute heart failure: experience in the emergency department at the Charles Nicole Hospital of Tunis from 2013 to 2014].

Introduction: Acute Heart Failure (AHF) is a specific syndromic disorder grouping several heterogeneous clinical conditions frequently seen in the emergency department. This study aimed to describe the epidemiological, clinical, therapeutic and prognostic features of patients with AHF admitted to the emergency department.

Methods: We conducted a prospective, descriptive study in the emergency department.

Prognostic Value of Serum C-Reactive Protein in Spontaneous Intracerebral Hemorrhage: When Should We Take the Sample?

Background: Several studies showed a correlation between C-reactive protein and mortality in spontaneous intracerebral hemorrhage. However, the best time to measure C-reactive protein to assess prognosis is not yet clear. The purpose of this study was to determine if initial or H24-C-reactive protein is independently associated with 30-day mortality in intracerebral hemorrhage.

Culture conditions and salt effects on essential oil composition of sweet marjoram (Origanum majorana) from Tunisia.

O. majorana shoots were investigated for their essential oil (EO) composition. Two experiments were carried out; the first on hydroponic medium in a culture chamber and the second on inert sand in a greenhouse for 20 days.

Salt effect on phenolics and antioxidant activities of Tunisian and Canadian sweet marjoram (Origanum majorana L.) shoots.

Background: Two varieties of Origanum majorana (Canadian and Tunisian) were evaluated for their phenolic, flavonoid and tannin contents, individual phenolic compounds and antioxidant activities under NaCl constraint.

Results: The results showed a significant variability in phenolic composition and antioxidant behavior between the two varieties under salt stress. The phenolic composition of methanolic extracts was determined by reversed-phase high-performance liquid chromatography.

Salt effects on Origanum majorana fatty acid and essential oil composition.

Background: The effects of salt on the essential oil yield and fatty acid composition of aerial parts of two marjoram varieties were investigated. Plants with 6 leaves were treated with NaCl (75mM).

Results: Salt treatment led to a reduction in aerial part growth.

The impact of genotype and salinity on physiological function, secondary metabolite accumulation, and antioxidative responses in lettuce.

Salinity inhibits plant growth due to osmotic and ionic effects. However, little is known about the impact of genotype and salinity on biochemical and molecular processes in the leafy vegetable lettuce. We report here evaluations of two lettuce types, Verte (NaCl tolerant) and Romaine (NaCl sensitive), under iso-osmotic 100 mM NaCl and 77 mM Na(2)SO(4) treatments.

Comparative effect of potassium on K and Na uptake and transport in two accessions of Arabidopsis thaliana during salinity stress.

Potassium-sodium interaction was compared in two natural accessions of Arabidopsis thaliana, Columbia-0 and NOK2. Seedlings were grown in the presence of 0 or 50 mM NaCl and 0.1; 0.
