BACKGROUND The origin and formed family characteristics are related to physician's professional career. The purpose of this study was to know and compare by sex the characteristics of the origin family and formed family of women and men family physician in Andalusia. METHODS Cross sectional and multicenter study. SETTING Urban primary health care centres from Andalusian province capitals. PARTICIPANTS Physician of primary health care centres. INCLUSION CRITERIA at least one year using computerized medical history with the same quota patients. Multistage random sample, 88 primary health care centres and 500 physicians, 50% of both sexes (alpha=5%, power=90%, precision=15%). Postal auto administrated questionnaire. VARIABLES sex, age, tutor of resident in family medicine, last father's activity, last mother's activity, number of brothers or sisters, family situation, last couple's activity (if any), to have or not children. RESULTS 73.6 % responses. In no responses there weren't differences of sex neither tutor of resident in family medicine. Mean age: women physicians 49.5 +/- 4.3 and men physician 51.3 +/- 4.9 (p= or < 0.005). Postgraduate formation in family medicine: 42.2% of women and 33.3% of men (p=0.016). Live alone: 6.1% of women physician and 2.7% men physician (p=0.005). Live alone with children 9.9% of women and 2.2% of men (p=0.005). 16.5% of women and 10.2% of men don t have children (p=0.077). 21.1% of men physician s couples work only at home vs. 0.1% of women physician s couples (p= or < 0.005). 46% of women physician s couples is also physician vs. 22% of men physician s couples (p= or < 0.005). No significant differences registered in parent s activities neither in the number of brother or sisters. CONCLUSION There are no significant differences in physician s origin family. However important differences in the characteristics of formed family are observed in both sexes.

The cervico-thoracic outlet compression syndrome. Analysis of surgical treatment.

Surgical treatment of the thoracic outlet compression syndrome is being presently reconsidered. Until these last few years, there was the choice between two interventions only: scalenotomy, a simple operation entailing no complication, but with a 60% recurrence rate--or the resection of the first rib through an axillary approach, an efficacious intervention which caused, however, serious nervous complications in 14% of treated cases. The follow-up of 75 cases operated for a TOCS reveals to the authors that--all techniques taken into account--results are unsatisfactory in 33% of cases. These failures are due either to technical deficiencies, or to a complication arising in the course of the operation, or to an erroneous diagnosis. The authors resort to surgery only to treat serious vascular syndromes (absolute indication) or invalidating neurological compression syndromes, after failure of physical therapy (relative indication). They propose a cervical approach--the only one enabling a safe dissection of the brachial plexus--a partial scalenectomy, resection of all fibrous bands pressing on nervous trunks, or the resection of a cervical rib. Should the costo-clavicular space appear anatomically too narrow, the first rib, already partially freed by the cervical approach, will be resected through the axillary route.

The role of C-Jun N-terminal kinase in a mouse model of intracerebral hemorrhage

Background: Intracerebral hemorrhage (ICH) is a subtype of stroke characterized by a haematoma within the brain parenchyma resulting from blood vessel rupture and with a poor outcome. In ICH, the blood entry into the brain triggers toxicity resulting in a substantial loss of neurons and an inflammatory response. At the same time, blood-brain barrier (BBB) disruption increases water content (edema) leading to growing intracranial pressure, which in turn worsens neurological outcome. Although the clinical presentation is similar in ischemic and hemorrhagic stroke, the treatment is different and the stroke type needs to be determined beforehand by imaging which delays the therapy. C-Jun N-terminal kinases (JNKs) are a family of kinases activated in response to stress stimuli and involved in several pathways such as apoptosis. Specific inhibition of JNK by a TAT-coupled peptide (XG-102) mediates strong neuroprotection in several models of ischemic stroke in rodents. Recently, we have observed that the JNK pathway is also activated in a mouse model of ICH, raising the question of the efficacy of XG-102 in this model. Method: ICH was induced in the mouse by intrastriatal injection of bacterial collagenase (0,1 U). Three hours after surgery, animals received an intravenous injection of 100 mg/kg of XG-102. The neurological outcome was assessed everyday until sacrifice using a score (from 0 to 9) based on 3 behavioral tests performed daily until sacrifice. Then, mice were sacrificed at 6 h, 24 h, 48 h, and 5d after ICH and histological studies performed. Results: The first 24 h after surgery are critical in our ICH mice model, and we have observed that XG-102 significantly improves neurological outcome at this time point (mean score: 1,8 + 1.4 for treated group versus 3,4+ 1.8 for control group, P<0.01). Analysis of the lesion volume revealed a significant decrease of the lesion area in the treated group at 48h (29+ 11mm3 in the treated group versus 39+ 5mm3 in the control group, P=0.04). XG-102 mainly inhibits the edema component of the lesion. Indeed, a significant inhibition Journal of Cerebral Blood Flow & Metabolism (2009) 29, S490-S493 & 2009 ISCBFM All rights reserved 0271-678X/09 $32.00 www.jcbfm.com of the brain swelling was observed in treated animals at 48h (14%+ 13% versus 26+ 9% in the control group, P=0.04) and 5d (_0.3%+ 4.5%versus 5.1+ 3.6%in the control group, P=0.01). Conclusions: Inhibition of the JNK pathway by XG- 102 appears to lead to several beneficial effects. We can show here a significant inhibition of the cerebral edema in the ICH model providing a further beneficial effect of the XG-102 treatment, in addition to the neuroprotection previously described in the ischemic model. This result is of interest because currently, clinical treatment for brain edema is limited. Importantly, the beneficial effects observed with XG-102 in models of both stroke types open the possibility to rapidly treat stroke patients before identifying the stroke subtype by imaging. This will save time which is precious for stroke outcome.

The stable isotope composition of ostracod fossils is useful for palaeoenvironmental reconstruction. Laboratory as well as 'natural environment' cultures demonstrate that the carbon and oxygen isotope compositions of ostracod shells faithfully record the environmental conditions at the time of valve precipitation. Oxygen isotope composition of ostracod calcite reflects the composition and temperature of the host water, but ostracod shells are enriched in 18O compared to the value expected for inorganic calcite precipitating under equilibrium under the same conditions. This 'vital effect' is generally constant for closely related species and equals 1.5 to 3 0/00 for Candoninae, 0 to 2.5 0/00 for Cyprididae and 0.8 to 1.5 0/00 for Cytheroidea. The carbon isotope composition of ostracod calcite is controlled by a complex interaction between the ecology of the species and environmental parameters. Previous natural environmental studies suggest that many (but not all) taxa crystallize their shells in or very close to equilibrium with the carbon isotope composition of dissolved inorganic carbon, and that the composition of littoral, epifaunal species reflects seasonal variation in the carbon isotope composition of dissolved inorganic carbon of bottom water according to their life cycles, while that of deep-water, infaunal species reflects the variation interstitial pore water according to microhabitat preferences.

Electrophoretic characteristics of monoclonal immunoglobulin G of different subclasses.

Monoclonal IgG are commonly observed in various B cell disorders, of which multiple myeloma is the most clinically relevant. In a series of serum samples, we identified by immunofixation 73 monoclonal IgG, including 63 IgG(1), 4 IgG(2), 5 IgG(3), and 1 IgG(4). The light chains were of kappa type in 45 cases, and of lambda type in 28 cases. These monoclonal IgG were further characterized by high resolution two-dimensional polyacrylamide gel electrophoresis (2-DE) in various isoelectric focusing conditions, as well as by 3-DE (2-DE of the proteins extracted from agarose after serum protein agarose electrophoresis). After 2-DE, 38 out of 73 monoclonal gamma chains (52%) were visualized using immobilized pH 3-10 gradients for isoelectric focusing. In 6 cases (8%), gamma chains were only detected using alkaline immobilized pH 6-11 gradients. In 3 cases (4%), 3-DE revealed monoclonal gamma chains hidden by polyclonal gamma chains. Finally, in 26 cases (36%), no monoclonal gamma chains were clearly visualized. Sixty-one monoclonal light chains (84%) were detected using immobilized pH 3-10 gradients, whereas 12 (16%) were not. Monoclonal gamma chains and light chains were highly heterogeneous in terms of pI and M(r). However, a statistically significant correlation (P<0.05) was observed between the position of the monoclonal IgG in agarose gel and the pI of their heavy and light chains (R=0.733, multiple linear regression). Because of the extreme diversity of their heavy and light chains, it appears that a classification of monoclonal IgG based only on their electrophoretic properties is not possible.

Effect of iron supplementation on fatigue in nonanemic menstruating women with low ferritin: a randomized controlled trial.

BACKGROUND: The true benefit of iron supplementation for nonanemic menstruating women with fatigue is unknown. We studied the effect of oral iron therapy on fatigue and quality of life, as well as on hemoglobin, ferritin and soluble transferrin receptor levels, in nonanemic iron-deficient women with unexplained fatigue. METHODS: We performed a multicentre, parallel, randomized controlled, closed-label, observer-blinded trial. We recruited from the practices of 44 primary care physicians in France from March to July 2006. We randomly assigned 198 women aged 18-53 years who complained of fatigue and who had a ferritin level of less than 50 ug/L and hemoglobin greater than 12.0 g/dL to receive either oral ferrous sulfate (80 mg of elemental iron daily; n = 102) or placebo (n = 96) for 12 weeks. The primary outcome was fatigue as measured on the Current and Past Psychological Scale. Biological markers were measured at 6 and 12 weeks. RESULTS: The mean score on the Current and Past Psychological Scale for fatigue decreased by 47.7% in the iron group and by 28.8% in the placebo group (difference -18.9%, 95% CI -34.5 to -3.2; p = 0.02), but there were no significant effects on quality of life (p = 0.2), depression (p = 0.97) or anxiety (p = 0.5). Compared with placebo, iron supplementation increased hemoglobin (0.32 g/dL; p = 0.002) and ferritin (11.4 μg/L; p < 0.001) and decreased soluble transferrin receptor (-0.54 mg/L; p < 0.001) at 12 weeks. INTERPRETATION: Iron supplementation should be considered for women with unexplained fatigue who have ferritin levels below 50 μg/L. We suggest assessing the efficiency using blood markers after six weeks of treatment. Trial registration no. EudraCT 2006-000478-56.

Severe traumatic brain injury in a high-income country: an epidemiological study.

This adult cohort determined the incidence and patients' short-term outcomes of severe traumatic brain injury (sTBI) in Switzerland and age-related differences. A prospective cohort study with a follow-up at 14 days was performed. Patients ≥16 years of age sustaining sTBI and admitted to 1 of 11 trauma centers were included. sTBI was defined by an Abbreviated Injury Scale of the head (HAIS) score >3. The centers participated from 6 months to 3 years. The results are presented as percentages, medians, and interquartile ranges (IQRs). Subgroup analyses were performed for patients ≤65 years (younger) and >65 (elderly). sTBI was observed in 921 patients (median age, 55 years; IQR, 33-71); 683 (74.2%) were male. Females were older (median age, 67 years; IQR, 42-80) than males (52; IQR, 31-67; p<0.00001). The estimated incidence was 10.58 per 100,000 inhabitants per year. Blunt trauma was observed in 879 patients (95.4%) and multiple trauma in 283 (30.7%). Median Glasgow Coma Score (GCS) on the scene was 9 (IQR 4-14; 8 in younger, 12 in elderly) and in emergency departments 5 (IQR, 3-14; 3 in younger, 8 in elderly). Trauma mechanisms included the following: 484 patients with falls (52.6%; younger, 242 patients [50.0%]; elderly, 242 [50.0%]), 291 with road traffic accidents (31.6%; younger, 237 patients [81.4%]; elderly, 54 [18.6%]), and 146 with others (15.8%). Mortality was 30.2% (24.5% in younger, 40.9% in elderly). Median GCS at 14 days was 15 (IQR, 14-15) without differences among subgroups. Estimated incidence of sTBI in Switzerland was low, age was high, and mortality considerable. The elderly had higher initial GCS and a higher death rate, but high GCS at 14 days.

Acute inflammatory reaction associated with endoluminal bypass grafts.

PURPOSE: Nonspecific inflammatory reactions characterized by local tenderness, fever, and flu-like discomfort have been seen in patients undergoing endoluminal graft placement in the abdominal aorta or the femoral arteries. We undertook a study to assess the clinical and laboratory parameters of this inflammation. METHODS: Ten patients with femoropopliteal artery (n = 9) or aortic (n = 1) lesions were treated with EndoPro System 1 stent-grafts made of nitinol alloy and covered with a polyester (Dacron) fabric. Eleven patients implanted with a bare nitinol stent served as the control group. RESULTS: In the stent-graft group, four patients showed clinical signs of acute inflammation manifested by fever and local tenderness. Three of these patients suffered thrombosis of the stent-grafts during the first month of follow-up. Plasma levels of interleukin-1 beta and interleukin-6 in all stent-graft patients were markedly increased 1 day after intervention (7.3 +/- 2.8 versus 90.2 +/- 34.1 pg/mL and 15.6 +/- 5.8 versus 175.5 +/- 66.3 pg/mL, respectively; p < 0.01). This was followed by an increase in fibrinogen (3.0 +/- 0.2 versus 5.0 +/- 0.2 g/L; p < 0.05) and C-reactive protein (14.6 +/- 3.3 versus 77.5 +/- 15.0 mg/L; p < 0.01) at 1 week. No direct correlation between the inflammatory markers and symptoms could be found. In vitro analysis showed that individual components of the stent-graft did not activate human neutrophils, whereas the intact stent-graft itself induced a marked neutrophil activation. CONCLUSIONS: The component of the self-expanding stent-graft responsible for the nonspecific inflammatory reaction was not identified in this study. It is likely that the stent-graft itself or some as yet unrecognized element of the device other than the Dacron fabric or metal alloy may be a potent in vivo inducer of cytokine reaction by neutrophils.

Prevalences of masked and white-coat hypertension in the Lausanne population: the Hercules Study

Background and Objectives: Few population-based data on the prevalences of masked and white-coat hypertension exist. We collected 24-hour ambulatory blood pressure (BP) and urine in a random subset of participants to the population-based CoLaus study. Methods: Clinic BP was measured using an Omron HEM 907 device and ambulatory BP (ABP) using a Diasys Integra device. Masked hypertension (MH) was defined as clinic BP < 140/90mm Hg and 24-hour ABP >¼135/85mmHg. White coat hypertension (WCH) was defined as clinic BP >¼ 140/90mm Hg and ABP <135/85mm Hg. Microalbuminuria was defined as present if urinary albumin excretion was > 20mg/min. Results: The 198 men and 213 women were aged (mean_SD) 56.2_10.7 and 57.2_10.3 years and had mean urinary excretion of 148_65 and 122_52 mmol/24 h for sodium and 70_24 and 5721 mmol/24 h for potassium, respectively. In men and women, the prevalences were 34.9% and 31.0% for clinic hypertension, 42.9% and 32.9% for ambulatory hypertension, 12.6% and 5.6% for MH, and 4.5% and 3.8% for WCH, respectively. The higher prevalence of MH in men was explained, in part, by higher alcohol consumption and smoking. Participants with MH tended to have higher microalbuminuria (13.5% vs 5.8%, P¼0.067). Participants with WCH had no microalbuminuria. Conclusions: In the Lausanne population aged 38 to 78 years, the prevalence of hypertension based on ABP was high, despite moderate dietary salt intake. Men had higher prevalence of MH then women. The prevalence of WCH was low and similar in men and women. MH tended to be associated with early kidney damage.

Ab initio benchmark study for the oxidative addition of CH4 to Pd: importance of basis-set flexibility and polarization

To obtain a state-of-the-art benchmark potential energy surface (PES) for the archetypal oxidative addition of the methane C-H bond to the palladium atom, we have explored this PES using a hierarchical series of ab initio methods (Hartree-Fock, second-order Møller-Plesset perturbation theory, fourth-order Møller-Plesset perturbation theory with single, double and quadruple excitations, coupled cluster theory with single and double excitations (CCSD), and with triple excitations treated perturbatively [CCSD(T)]) and hybrid density functional theory using the B3LYP functional, in combination with a hierarchical series of ten Gaussian-type basis sets, up to g polarization. Relativistic effects are taken into account either through a relativistic effective core potential for palladium or through a full four-component all-electron approach. Counterpoise corrected relative energies of stationary points are converged to within 0.1-0.2 kcal/mol as a function of the basis-set size. Our best estimate of kinetic and thermodynamic parameters is -8.1 (-8.3) kcal/mol for the formation of the reactant complex, 5.8 (3.1) kcal/mol for the activation energy relative to the separate reactants, and 0.8 (-1.2) kcal/mol for the reaction energy (zero-point vibrational energy-corrected values in parentheses). This agrees well with available experimental data. Our work highlights the importance of sufficient higher angular momentum polarization functions, f and g, for correctly describing metal-d-electron correlation and, thus, for obtaining reliable relative energies. We show that standard basis sets, such as LANL2DZ+ 1f for palladium, are not sufficiently polarized for this purpose and lead to erroneous CCSD(T) results. B3LYP is associated with smaller basis set superposition errors and shows faster convergence with basis-set size but yields relative energies (in particular, a reaction barrier) that are ca. 3.5 kcal/mol higher than the corresponding CCSD(T) values

Impact of pharmacist care in the management of cardiovascular disease risk factors: a systematic review and meta-analysis of randomized trials.

BACKGROUND: Pharmacists may improve the clinical management of major risk factors for cardiovascular disease (CVD) prevention. A systematic review was conducted to determine the impact of pharmacist care on the management of CVD risk factors among outpatients. METHODS: The MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials that involved pharmacist care interventions among outpatients with CVD risk factors. Two reviewers independently abstracted data and classified pharmacists' interventions. Mean changes in blood pressure, total cholesterol, low-density lipoprotein cholesterol, and proportion of smokers were estimated using random effects models. RESULTS: Thirty randomized controlled trials (11 765 patients) were identified. Pharmacist interventions exclusively conducted by a pharmacist or implemented in collaboration with physicians or nurses included patient educational interventions, patient-reminder systems, measurement of CVD risk factors, medication management and feedback to physician, or educational intervention to health care professionals. Pharmacist care was associated with significant reductions in systolic/diastolic blood pressure (19 studies [10 479 patients]; -8.1 mm Hg [95% confidence interval {CI}, -10.2 to -5.9]/-3.8 mm Hg [95% CI,-5.3 to -2.3]); total cholesterol (9 studies [1121 patients]; -17.4 mg/L [95% CI,-25.5 to -9.2]), low-density lipoprotein cholesterol (7 studies [924 patients]; -13.4 mg/L [95% CI,-23.0 to -3.8]), and a reduction in the risk of smoking (2 studies [196 patients]; relative risk, 0.77 [95% CI, 0.67 to 0.89]). While most studies tended to favor pharmacist care compared with usual care, a substantial heterogeneity was observed. CONCLUSION: Pharmacist-directed care or in collaboration with physicians or nurses improve the management of major CVD risk factors in outpatients.

A relação entre polifarmácia, complicações crônicas e depressão em portadores de Diabetes Mellitus Tipo 2

Os objetivos deste estudo foram: caracterizar a polifarmácia entre portadores de Diabetes Mellitus tipo2(DM2); e correlacionar polifarmácia e número de complicações do DM2 com indicadores de depressão (Inventário de Depressão de Beck[IDB] e cortisol urinário[CORT]). A amostra foi composta por 40 pacientes da Liga de Diabetes do HCFM-USP, avaliados quanto aos indicadores de depressão (CORT e IDB) e quanto à prática de polifarmácia e número de complicações do DM2. Os resultados mostraram que os medicamentos utilizados foram: antidiabéticos orais, insulinas, anti-hipertensivos, diuréticos, anti-lipêmicos e trombolíticos. No grupo estudado, 75% fizeram uso diário de 5 a 8 medicamentos, e 12,5% de 8 medicamentos/dia ou mais; todos fizeram no mínimo 3 tomadas diárias, 60% tinham entre 1 e 3 complicações do DM2, e 22,5% tinham 3 ou mais. A correlação entre os indicadores de depressão(IDB e CORT), o número de medicamentos e o número de complicações do DM2 não foi estatisticamente significante. No entanto, houve correlação positiva entre CORT e número de tomadas diárias de medicamentos (Spearman,r=0.319, p=0.019).
