Although many organisations have implemented structured training programmes, limited evidence exists on their effectiveness in improving physician interpersonal skills. This study aims to evaluate the effectiveness of a standardised, multifaceted, interpersonal skills development programme for hospital physicians.

There exists some literature demonstrating that the nociceptive stimuli experienced during surgery are responsible for peripheral and central sensitization phenomena, which can in turn lead to persistent postsurgical pain. An individualized approach to the evaluation and treatment of perioperative nociception is beneficial in order to avoid the sensitization phenomena that leads to prolonged postoperative pain and to minimize the consumption of opiates and their adverse effects.

Introduction: Nitric oxide (NO) precursor supplementation has been shown to increase NO bioavailability and can potentially improve vascular function and exercise performance. It remains unclear whether the combination of NO precursor supplementation and exercise training has synergic effects on exercise performance. This study aims to assess the effect of chronic nitrate and citrulline intake on exercise training adaptations in healthy young individuals.

The purpose of our study was to estimate the prevalence of unknown cases of ocular hypertension, glaucoma suspects, and glaucoma in patients consulting for refractive disorders in France.
Methods: A retrospective study in the Point Vision ophthalmology center was led in Toulouse, France.
Purpose: Uncorrected refractive errors are the first cause of vision impairment worldwide. High myopia is a frequent cause of sight-threatening chorioretinal complications. The aim of this study was to evaluate the prevalence of macular complications, visual impairment and blindness in patients with myopia.

It remains unclear whether older adults who experience a decreased NO bioavailability may benefit from chronic NO precursor supplementation. This randomised, double-blind, trial aims to assess the effect of chronic NO precursor intake on vascular function and exercise performance in older adults (60-70 years old).

HIT confirmation directly impacts on anticoagulant strategy requiring no delay unfractionated heparin discontinuation to be replaced by alternative systemic anticoagulant treatment.
Case Presentation: We report two clinical cases of HIT occurring during ECMO in various settings with subsequent recovery with argatroban and provide literature review to help physicians treat HIT during ECMO in clinical daily practice.
Refractive error (RE), particularly myopia, is the first cause of visual impairment throughout the world. This study aimed to depict the prevalence of myopia in a multicentric series of French individuals.This cross-sectional analysis was carried out between January 2012 and November 2013 in eye clinics dedicated to REs.

Materials And Methods: This multicentric open study was carried out in adult patients suffering from OAG or simple OHT (naive or previously treated with monotherapy) and needing a change or initiation of anti-glaucomatous treatment. One drop of latanoprost 0.
Purpose: The purpose of this study was to describe the distribution and characteristics (age, duration, type, treatment, etc.) of ocular hypertension and glaucoma in French ophthalmologic practices.
Methods: The French glaucoma and ocular hypertension 1-day study is a descriptive cross-sectional "1-day" type survey, conducted among all ophthalmologists of mainland France.
The effects of zinc supplementation on zinc status and on clinical and biological indicators of inflammation were investigated in 18 patients with chronic inflammatory rheumatic diseases and in 9 healthy control subjects. Patients with mild and recent onset disease were assigned to a 60-d trial to receive either 45 mg Zn (as gluconate)/d or a placebo, while control subjects received the zinc supplement. Baseline mean plasma zinc of the patients was low whereas mononuclear cell zinc content was elevated, suggesting a redistribution of the element related to the inflammatory process rather than to a zinc-deficient state.

Although zinc intake is reduced in elderly people, its deficiency and effects on cell-mediated immunity of the elderly have not been established. Subjects enrolled in "A Model Health Promotion and Intervention Program for Urban Middle Aged and Elderly Americans" were assessed for nutrition and zinc status.

The aim of this study was to document the influence on zinc bioavailability of factors such as the chemical form of zinc, the pharmaceutical form, and the division of the administered dose. The pharmacokinetic parameters indicate for gelatin capsules without excipients taken in a non divided dose better performances for zinc gluconate in comparison to zinc sulfate.

It is catalyzed by peptidylglycine alpha-amidating monooxygenase (PAM), an enzyme that is copper-dependent. We show here that alterations of copper stores in cultured cells from different origins (pancreas and hypothalamus) affect the immunoreactivity of thyrotropin-releasing hormone (TRH) and corticotropin-releasing factor (CRF) (two alpha-amidated peptides).

The pharmacokinetic parameters were calculated by a method suitable to the characterization of rebound effects (recycling of the element in the gastrointestinal tract). In fasting state, the parameters were comparable to those previously collected in the same subjects with oral 45 mg zinc as sulfate, except with very significantly higher Cmax and area under curve (AUC), showing a better bioavailability for zinc in the commercial form.

We have previously demonstrated that acute prednisolone administration induces a moderate but sustained increase in plasma copper in healthy rats while it induces a more pronounced but shorter increase in rats with adjuvant arthritis. In the present study we have investigated the effects of chronic prednisolone administration (around 0.

Since VIP is the mediator of the syndrome and is biologically active under its amidated form, the enzymatic alpha-amidating activity was investigated and characterized in tumour extract; using the synthetic substrate D-Tyr-Val-Gly, the enzyme displayed an optimal activity at pH 7.0, under aerobic conditions and with 35 microM CuSO4 and 3 mM ascorbate as co-factors.

The modification is related to an induction of liver metallothionein causing an accumulation of the element in this organ. The changes in zinc metabolism induced by adjuvant arthritis in rats evidenced a redistribution of body zinc with a rapid and sustained decrease in plasma zinc that occurred simultaneously with an increase in liver zinc levels, and slower modification in erythrocyte and femur zinc concentrations.
