Clinical management of immunocompetent hospitalized patients with community-acquired pneumonia.

Background: Clinical practices and guidelines may differ regarding the management of inpatients with community-acquired pneumonia (CAP). Methods: The management of 152 consecutive CAP inpatients (70+/-17 years) admitted to a teaching hospital was analyzed retrospectively and compared with published data and an evidence-based guideline developed at our institution. Results: Of the patients studied, 64% had a high prognostic score index (PSI), 14% were admitted to the ICU, and 4.6% died. Initially, patients received either a one-drug (47%) or a two-drug (53%) antibiotic regimen. None of the 20 PSI parameters, and neither the PSI nor admission to the ICU, was associated with the initial antibiotic regimen. Agreement between current practice and our guideline was low (kappa=0.16). Following the recommendations would have led to a decrease of 51% in the initial two-drug regimen. The duration of i.v. antibiotherapy was higher in patients following the two-drug regimen (142+/-150 vs. 102+/-60 h, P<0.05). Chest physiotherapy (CP) and bronchodilatators (BD) were prescribed in 72% and 54% of cases, respectively (median duration 10 days). Conclusions: The variations observed in the clinical management of CAP inpatients were not in agreement with published guidelines. The overuse of a two-drug regimen, CP, and BD necessitates the development and implementation of evidence-based guidelines proposing detailed steps for the management of CAP inpatients.

Higher education in nursing: the faculty work process in different institutional contexts

Objective To analyze the characteristics of faculty work in nursing higher education. Method An exploratory qualitative study with a theoretical-methodological framework of dialectical and historical materialism. The faculty work process was adopted as the analytical category, grounded on conceptions of work and professionalism. Semi-structured interviews were conducted with 24 faculty members from three higher education institutions in the city of São Paulo, classified according to the typology of institutional contexts. Results The faculty members at these higher education institutions are a heterogeneous group, under different working conditions. Intensification and precarious conditions of the faculty work is common to all three contexts, although there are important distinctions in the practices related to teaching, research and extension. Conclusion Faculty professionalization can be the starting point for analyzing and coping with such a distinct reality of faculty work and practice.


Metadata For Identity Management of Population Registers

A population register is an inventory of residents within a country, with their characteristics (date of birth, sex, marital status, etc.) and other socio-economic data, such as occupation or education. However, data on population are also stored in numerous other public registers such as tax, land, building and housing, military, foreigners, vehicles, etc. Altogether they contain vast amounts of personal and sensitive information. Access to public information is granted by law in many countries, but this transparency is generally subject to tensions with data protection laws. This paper proposes a framework to analyze data access (or protection) requirements, as well as a model of metadata for data exchange.

Prise en charge des séminomes sécrétants de l'hormone chorionique gonadotrope [Management of chorionic gonadotropin-producing seminoma.]

INTRODUCTION: The human chorionic gonadotropin (HCG)-producing seminoma is an uncommon entity and belongs to the overall category of pure seminoma. METHOD: The literature search was conducted on Medline(®) using the words: seminoma, human chorionic gonadotropin, HCG combined with radiotherapy, chemotherapy, surveillance, management and prognosis. We extended our search of similar references by related articles function, reading the bibliography of identified articles and publications available on Medline(®) from the same authors. This research was limited to English or French publications. Articles were eligible if they were randomized trials, prospective, retrospective or systematic reviews of the literature. RESULTS: Few articles were found on this subject. We selected the most relevant series while summarizing various parameters (epidemiological, clinical, therapeutic and prognostic). CONCLUSIONS: Clinical presentation, behaviour and work-up for HCG-producing seminoma should be the same as for non-secreting seminoma. HCG-producing seminoma tumours are not more resistant to radiation therapy or chemotherapy than non-secreting seminoma tumours. Radiotherapy remains an excellent option in stage I and IIA disease with chemotherapy as an alternative; overall prognosis is excellent. Surveillance in early stage HCG-producing seminoma is followed by a higher relapse than in early stage non-secreting seminoma.

Prognostic factors and role of adjuvant therapies in the management of parasagittal meningiomas

Background: The goal of the present study was to retrospectively analyze our series of parasagittal meningiomas, treated by either single or combined therapies (surgery and/or SRS and FSRT), in order to determine the factors that influence patient outcome. Methods: Between January 1999 and May 2007, 37 parasagittal meningiomas were treated in our center. We compared the outcome of the parasagittal meningiomas in relation to the treatment and adjuvant treatment given, their location along the SSS, their volume, their histological and resection grade as well as the patient's sex and age to understand which factors influenced their natural history. Findings: Median follow-up was 6.7 years (2.4-12 years). Tumor grades and Simpson resection grade were distributed evenly along the SSS. The actuarial overall tumor control rate was 65.9%. Regression analysis showed, that the tumor histological grade and the Simpson resection grade were two significant factors in determining the tumor control (p<0.002 and p<0.008). Location along the SSS showed a lower control rate in the posterior third (p<0.002). Sex, age and tumor volume, however, were not significant factors. Moreover, and unexpectedly, the In our series, the proportion of adjuvant treatment was much higher than in former described series (39% vs 7%) but with similar control rate and lower morbidity and mortality. Conclusions: In our series, histological grade and Simpson grade are independent factors for recurrence and tumor control. Interestingly, location in the posterior third of the SSS seems to be another independent factor for recurrence. In order to avoid major morbidities related to surgery we advocate earlier use of adjuvant therapies for higher histological grade tumors and for tumors located at the posterior portion of the SSS, but definitive conclusions might warrant a larger series.

MANAGEMENT OF IRRIGATION AND NITROGEN FERTILIZERS TO REDUCE AMMONIA VOLATILIZATION

ABSTRACT Nitrogen losses by ammonia (NH3) volatilization can be reduced by appropriate irrigation management or by alternative N sources, replacing urea. The objective of this study was to evaluate the efficiency of irrigation management and N source combinations in decreasing NH3 volatilization from an Argissolo Vermelho Distrófico típico cultivated for 28 years with black oat (Avena strigosa) and maize (Zea mays), under no-tillage in the region of Depressão Central, Rio Grande do Sul, Brazil. The experiment was arranged in a randomized block design with split plots with three replications, where the main plots consisted of irrigation systems: no irrigation; irrigation immediately before and irrigation immediately after fertilization. The subplots were treated with different N sources: urea, urea with urease inhibitor and slow-release fertilizer, at an N rate of 180 kg ha-1, broadcast over maize, plus a control treatment without N fertilization. Ammonia volatilization was assessed using semi-open static collectors for 1, 2, 4, 6, and 10 days after N fertilization. In general, more than 90 % of total NH3-N losses occurred until three days after N fertilization, with peaks up to 15.4 kg ha-1 d-1. The irrigation was efficient to reduce NH3 losses only when applied after N fertilization. However, reductions varied according to the N fertilizer, and were higher for urea (67 %) and slightly lower for urea with urease inhibitor (50 %) and slow-release fertilizer (40 %), compared with the mean of the treatments without irrigation and irrigation before fertilization. The use of urea with urease inhibitor instead of urea was only promising under volatilization-favorable conditions (no irrigation or irrigation before N fertilization). Compared to urea, slow-release fertilizer did not reduce ammonia volatilization in any of the rainfed or irrigated treatments.

Oligoanalgesia in the emergency department: short-term beneficial effects of an education program on acute pain.

STUDY OBJECTIVE: Acute pain is the most frequent complaint in emergency department (ED) admissions, but its management is often neglected, placing patients at risk of oligoanalgesia. We evaluate the effect of the implementation of guidelines for pain management in ED patients with pain at admission or anytime during their stay in our ED. METHODS: This prospective pre-post intervention cohort study included data collection both before and after guideline implementation. Consecutive adult patients admitted with acute pain from any cause or with pain at any time after admission were enrolled. The quality of pain management was evaluated according to information in the ED medical records by using a standardized collection form, and its impact on patients was recorded with a questionnaire at discharge. RESULTS: Two hundred forty-nine and 192 patients were included during pre- and postintervention periods. Pain was documented in 61% and 76% of nurse and physician notes, respectively, versus 78% and 85% after the intervention (difference 17%/9%; 95% confidence interval [CI] 8% to 26%/2% to 17%, respectively). Administration of analgesia increased from 40% to 63% (difference 23%; 95% CI 13% to 32%) and of morphine from 10% to 27% (difference 17%; 95% CI 10% to 24%). Mean doses of intravenous morphine increased from 2.4 mg (95% CI 1.9 to 2.9 mg) to 4.6 mg (95% CI 3.9 to 5.3 mg); administration of nonsteroidal antiinflammatory drugs and acetaminophen increased as well. There was a greater reduction of visual analogue scale score after intervention: 2.1 cm (95% CI 1.7 to 2.4 cm) versus 2.9 cm (95% CI 2.5 to 3.3 cm), which was associated with improved patient satisfaction. CONCLUSION: Education program and guidelines implementation for pain management lead to improved pain management, analgesia, and patient satisfaction in the ED.

Pro-adrenomedullin usefulness in the management of children with community-acquired pneumonia, a preliminary prospective observational study

BackgroundIn adult population with community acquired pneumonia high levels of pro-adrenomedullin (pro-ADM) have been shown to be predictors of worse prognosis. The role of this biomarker in pediatric patients had not been analyzed to date. The objective of this study is to know the levels of pro-ADM in children with community acquired pneumonia (CAP) and analyze the relation between these levels and the patients¿ prognosis.FindingsProspective observational study including patients attended in the emergency service (January to October 2009) admitted to hospital with CAP and no complications at admission. The values for pro-ADM were analyzed in relation to: need for oxygen therapy, duration of oxygen therapy, fever and antibiotic therapy, complications, admission to the intensive care unit, and length of hospital stay. Fifty patients were included. Ten presented complications (7 pleural effusion). The median level of pro-ADM was 1.0065¿nmol/L (range 0.3715 to 7.2840¿nmol/L). The patients presenting complications had higher levels of pro-ADM (2.3190 vs. 1.1758¿nmol/L, p¿=¿0.013). Specifically, the presence of pleural effusion was associated with higher levels of pro-ADM (2.9440 vs. 1.1373¿nmol/L, p¿<¿0.001).ConclusionsIn our sample of patients admitted to hospital with CAP, pro-ADM levels are related to the development of complications during hospitalization.

Open licensing's impact on higher education resources colombian and catalan approaches

A new initiative has sprung on the path created by the Open Access (OA) movement: Open Education (OE). The initiative's aim is to open up all educational resources at all learning levels. In order to achieve this goal, several international institutions, like UNESCO and the OECD, have published reports, surveys and documents to help educational institutions in this endeavor. This global initiative needs a legal framework; as a result, efforts thus far have usually resorted to Open Licensing (OL), especially Creative Commons (CC) licensing. In fact, as a response to this new movement, Creative Commons launched a new program, ccLearn , which recognizes open licensing's impact on education and directly supports the idea of open educational resources (OER). However, there still remain a good amount of open questions: What is happening locally with OL in higher education? How are educational institutions receiving the initiative? How is it that the OL initiative relates to educational resources? Are there local examples of open educational resources (OER)? How do these local instances incorporate CC into their educational frameworks?. To this effect, this analysis aims to focus on the legal approach and specifically on the way the educational sector is using open licenses outside the English speaking world. It will do so by looking at the current situation in two specific scenarios, the Colombian and the Catalan experiences with open educational projects at the higher education level.

Management of hepatitis C virus (HCV) infection in drug substitution programs.

BACKGROUND: In Switzerland, intravenous drug use (IDU) accounts for 80% of newly acquired hepatitis C virus (HCV) infections. Early HCV treatment has the potential to interrupt the transmission chain and reduce morbidity/mortality due to decompensated liver cirrhosis and hepatocellular carcinoma. Nevertheless, patients in drug substitution programs are often insufficiently screened and treated. OBJECTIVE/METHODS: With the aim to improve HCV management in IDUs, we conducted a cross sectional chart review in three opioid substitution programs in St. Gallen (125 methadone and 71 heroin recipients). Results were compared with another heroin substitution program in Bern (202 patients) and SCCS/SHCS data. RESULTS: Among the methadone/heroin recipients in St. Gallen, diagnostic workup of HCV was better than expected: HCV/HIV-status was unknown in only 1% (2/196), HCV RNA was not performed in 9% (13/146) of anti-HCV-positives and the genotype missing in 15% (12/78) of HCV RNA-positives. In those without spontaneous clearance (two thirds), HCV treatment uptake was 23% (21/91) (HIV-: 29% (20/68), HIV+: 4% (1/23)), which was lower than in methadone/heroin recipients and particularly non-IDUs within the SCCS/SHCS, but higher than in the, mainly psychiatrically focussed, heroin substitution program in Bern (8%). Sustained virological response (SVR) rates were comparable in all settings (overall: 50%, genotype 1: 35-40%, genotype 3: two thirds). In St. Gallen, the median delay from the estimated date of infection (IDU start) to first diagnosis was 10 years and to treatment was another 7.5 years. CONCLUSIONS: Future efforts need to focus on earlier HCV diagnosis and improvement of treatment uptake among patients in drug substitution programs, particularly if patients are HIV-co-infected. New potent drugs might facilitate the decision to initiate treatment.

Diagnosis and management of blunt great vessel trauma.

Traditionally, thoracic aortic rupture, suspected after blunt thoracic trauma, is characterized by a chest radiograph showing a widened mediastinum. The diagnostic machinery consecutively activated still depends heavily on the pressure as additional traumatic lesions. A patient with additional cranio-cerebral trauma would typically undergo contrast-enhanced computed tomography or magnetic resonance imaging of head, chest, and other regions. In a number of patients these analyses would confirm the presence of blood in the mediastinum without formal proof of an aortic disruption. This is because mediastinal hematomas may be caused not only by an aortic rupture, but also by numerous other blood sources including fractures of the spine and other macro- and microvascular lesions providing similar images. Therefore, aortic angiography became our preferred diagnostic tool to identify or rule out acute traumatic lesions of not only the aorta but with great vessels. However recently, a number of traumatic aortic transsections have been identified by transoesophageal echocardiography (TEE). TEE has the additional advantage of being a bed-side procedure providing additional information about cardiac function. The latter analysis allows for identification and quantification of cardiac contusions, post-traumatic myocardial infarctions, and valvar lesions which are of prime importance to develop an adequate surgical strategy and to assess the risk of the numerous emergency procedures required in patients with polytrauma. The standard approach for repair of isthmic aortic rupture is through a lateral thoracotomy. Distal and proximal control of the aorta can be achieved in a substantial number of cases before complete aortic rupture occurs and a higher proportion of direct suture repair can be achieved under such circumstances. Most proximal descending aortic procedures are performed without cardiopulmonary bypass (clamp and go) but paraplegia may occur before, during, or after the procedure. Ascending aortic lesions and disruption of the aortic arch, the supra-aortic vessels, the main pulmonary arteries, the great veins as well as cardiac lesions are best approached through a sternotomy, which may have to be extended. Cardiopulmonary bypass allowing for deep hypothermia and circulatory arrest is often required and carries its own complications. It is not clear whether the increasing proportion of ascending aortic and cardiac lesions which are observed nowadays are due to a change in trauma mechanics (i.e., speed limits, seat belts, air-bags), an improvement of the diagnostic tools or both.

Bypass gastrique: prise en charge des complications et désagrements alimentaires [Gastric bypass: management of complications and food tolerance]

La chirurgie bariatrique est le seul traitement qui permette une perte pondérale significative sur le long terme mais le succès d'une telle intervention repose avant tout dans une sélection et une préparation attentive du patient. Une bonne connaissance des implications de l'opération permet de favoriser un changement de comportement alimentaire et par là aussi de diminuer les complications et les désagréments alimentaires. L'éducation du patient n'a de sens que si elle s'inscrit dans une prise en charge pluridisciplinaire, comprenant également un suivi diététique, planifié sur le long terme. La mastication, la vitesse d'ingestion des aliments, le fait de renoncer aux boissons gazeuses et de devoir boire régulièrement entre les repas, sont les éléments les plus difficiles à mettre en place pour le patient. Bariatric surgery is the only treatment inducing effective weight loss on the long term. The success of such an intervention is possible by carefully selecting and educating the candidates. Good understanding of the bariatric surgery implications allows the patients to modify their eating habits and thus decrease complications and food intolerance. Therefore patient education requires a multidisciplinary approach which implies the follow-up of a dietician on the long term. Mastication, speed of food ingestion, avoidance of carbonated beverages as well as the obligation to drink at frequent and regular intervals are the most difficult aspects to be taught to the patients

Risk factor profile and management of cerebrovascular patients in the REACH Registry.

BACKGROUND: Cerebrovascular disease (CVD) is a global public health problem. CVD patients are at high risk of recurrent stroke and other atherothrombotic events. Prevalence of risk factors, comorbidities, utilization of secondary prevention therapies and adherence to guidelines all influence the recurrent event rate. We assessed these factors in 18,992 CVD patients within a worldwide registry of stable outpatients. METHODS: The Reduction of Atherothrombosis for Continued Health Registry recruited >68,000 outpatients (44 countries). The subjects were mainly recruited by general practitioners (44%) and internists (29%) if they had symptomatic CVD, coronary artery disease, peripheral arterial disease (PAD) and/or >or=3 atherothrombotic risk factors. RESULTS: The 18,992 CVD patients suffered a stroke (53.7%), transient ischemic attack (TIA) (27.7%) or both (18.5%); 40% had symptomatic atherothrombotic disease in >or=1 additional vascular beds: 36% coronary artery disease; 10% PAD and 6% both. The prevalence of risk factors at baseline was higher in the TIA subgroup than in the stroke group: treated hypertension (83.5/82.0%; p = 0.02), body mass index >or=30 (26.7/20.8%; p < 0.0001), hypercholesterolemia (65.1/52.1%; p < 0.0001), atrial fibrillation (14.7/11.9%; p < 0.0001) and carotid artery disease (42.3/29.7%; p < 0.0001). CVD patients received antiplatelet agents (81.7%), oral anticoagulants (17.3%), lipid-lowering agents (61.2%) and antihypertensives (87.9%), but guideline treatment targets were frequently not achieved (54.5% had elevated blood pressure at baseline, while 4.5% had untreated diabetes). CONCLUSIONS: A high percentage of CVD patients have additional atherothrombotic disease manifestations. The risk profile puts CVD patients, especially the TIA subgroup, at high risk for future atherothrombotic events. Undertreatment is common worldwide and adherence to guidelines needs to be enforced.

The gendering of excellence through quality criteria: the case of the SNSF Professorships in Switzerland

The Swiss National Science Foundation Professorships Programme is presented as a scientific programme that aims to promote outstanding young scholars to professorial positions. Academic excellence is presented as the main selection criterion. The emphasis put on the research portfolio and on the age of the candidates means that the beneficiaries of these professorships put forward an image of excellence that is more embedded in data-based sciences than in the humanities and social sciences, thus strengthening the domination of a sector scientific activity essentially occupied by men over the sector that has opened up more widely to women. This paper aims to deconstruct the criteria of academic excellence as they appear in this programme and to show that what seem quality criteria are in fact inspired by a specific androcentric model. These biases tend to undermine the gender equality aims of the programme.
