Suicidal ideation and the risk of suicide in patients with fibromyalgia: a comparison with non-pain controls and patients suffering from low-back pain.

Fibromyalgia is associated with an increased rate of mortality from suicide. In fact, this disease is associated with several characteristics that are linked to an increased risk of suicidal behaviors, such as being female and experiencing chronic pain, psychological distress, and sleep disturbances. However, the literature concerning suicidal behaviors and their risk factors in fibromyalgia is sparse. The objectives of the present study were to evaluate the prevalence of suicidal ideation and the risk of suicide in a sample of patients with fibromyalgia compared with a sample of healthy subjects and a sample of patients with chronic low-back pain. We also aimed to evaluate the relevance of pain intensity, depression, and sleep quality as variables related to suicidal ideation and risks. Logistic regression was applied to estimate the likelihood of suicidal ideation and the risk of suicide adjusted by age and sex. We also used two logistic regression models using age, sex, pain severity score, depression severity, sleep quality, and disease state as independent variables and using the control group as a reference. Forty-four patients with fibromyalgia, 32 patients with low-back pain, and 50 controls were included. Suicidal ideation, measured with item 9 of the Beck Depression Inventory, was almost absent among the controls and was low among patients with low-back pain; however, suicidal ideation was prominent among patients with fibromyalgia (P<0.0001). The risk of suicide, measured with the Plutchik Suicide Risk Scale, was also higher among patients with fibromyalgia than in patients with low-back pain or in controls (P<0.0001). The likelihood for suicidal ideation and the risk of suicide were higher among patients with fibromyalgia (odds ratios of 26.9 and 48.0, respectively) than in patients with low-back pain (odds ratios 4.6 and 4.7, respectively). Depression was the only factor associated with suicidal ideation or the risk of suicide.

La perception de la productivité dans l'industrie hôtelière de luxe : le cas de la Suisse romande

La perception de la productivité SUMMARY The main objective of this thesis is the perception of the productivity in the luxury hospitality industry. Despite a lot of efforts which were already made in the field of the production of goods, this concept (productivity) still remains to be defined in the services sector, more still, in that of the luxury hospitality industry. Since the object of this study is the perception of productivity, we decided to analyze the elements considered to be relevant by the top management in this field. Then, it seemed important to evaluate these same elements for the categories of middle-management and by the in-line employees. As perception is not static, it is dependent in an indirect way on its improvement and however also with the means of improvement. The assumption of our work evokes the possible relationship between productivity and its perception (P), (Q) quality and profitability (R). On this basis we built the P-Q-R model: R=F(P,Q) Finally, our research on this model enabled us to establish a mathematical relation between the three predetermined elements: fR=fP+fQ+c That means that the function efficiency of a process of services -(fR) is the sum of its quality function (intrinsic and extrinsic)-(fP) and of its productivity function - fQ (and the constant of regression "c"). To increase the profitability of the most significant manner, it is necessary to increase at the same time the productivity and quality. On the other hand, according to this formula but also according to the perception of the managers, with a constant profitability, either the productivity decreases in favor of the increase in quality, or the reverse. If the dimensions of the model influence positively or negatively the production process of services, then those wí11 influence in same manner our model (P, Q, R). We advance a point of view saying that profitability depends on the labor productivity which follows same dynamics than the perception of the productivity. The identification of the labor productivity as an essential element of successful management of the hotel is fundamental. The question which always remains in suspense is however the relevance of the concept "labor productivity" for the luxury hospitality industry. It was not proven an obvious correlation between this notion and the one of profitability. We still remain at the stage of perception. It results that one interesting way of future research will be the study of this correlation. As in any kind of luxury industry, the real added value does not consist in the volume produced or in the speed with which the product/service is carried out but in the creativity involved in their results. Let us note that the field of luxury is extremely related to the emotions and to the experience provided to the customers. La perception de la productivité... RÉSUME L'objectif principal de cette thèse est la perception de la productivité dans l'hôtellerie de luxe. Malgré tous les efforts qui ont déjà été faits dans le domaine de la production de biens, ce concept (productivité) reste encore à définir dans le secteur des services, plus encore, dans celui de l'hôtellerie de luxe. Étant donné que l'objet de l'étude est la perception de la productivité, nous avons décidé d'analyser les éléments jugés pertinents par les cadres dirigeants dans ce domaine. Puis, il nous a semblé important d'évaluer ces mêmes éléments pour les catégories de cadres moyens et par les employés in-line. Comme la perception n'est pas statique, elle est liée d'une manière indirecte à son amélioration et cependant également aux moyens d'amélioration. L'hypothèse de notre travail évoque la possible relation entre la productivité et sa perception (P), la qualité (Q) et la rentabilité (R). Sur cette base nous avons construit le modèle P-Q-R de départ R=f(P,Q) Finalement, notre recherche sur ce modèle nous a permis d'établir une relation mathématique entre les trois construits prédéterminés: fR=fP+fQ+c Cela signifie que la fonction rentabilité d'un processus de services -(fR) est la somme de sa fonction qualité (intrinsèque et extrinsèque)-fP et de sa fonction productivité -fQ (plus la constante de régression « c ») Pour augmenter la rentabilité de la manière la plus significative, il faut augmenter en même temps la productivité et la qualité. En revanche, selon cette formule mais selon aussi la perception des managers, à une rentabilité constante, soit la productivité diminue en faveur de l'augmentation de la qualité, soit l'inverse. Si les dimensions du modèle influencent positivement ou négativement le processus de production de services, alors celles-ci vont influencer de la même manière les construits de notre modèle (P, Q, R). Nous avançons un point de vue disant que la rentabilité dépend de la productivité du travail qui suit la même dynamique que la perception de la productivité. L'identification de la productivité du travail comme élément essentiel de gestion réussie de l'hôtel s'avère fondamentale. La question qui reste toujours en suspens est pourtant la pertinence de la notion «productivité du travail » pour l'industrie hôtelière de luxe. Il n'a pas été prouvé une corrélation évidente entre cette notion et celle de la profitabilité. Nous restons donc ici encore au stade de perception. Il en résulte que l'une des voies les plus intéressantes de recherche future sera l'étude de cette corrélation. Comme dans toute industrie de luxe, la vraie valeur ajoutée ne consiste pas toujours dans le volume produit, ni dans la vitesse avec laquelle le produit/service est réalisé, mais parfois dans la créativité emmagasinée dans ces résultats. Notons que le domaine de luxe est extrêmement lié aux émotions et à l'expérience fournie aux clients.

Locating and extracting the textual content from complex colour images using techniques inspired by human perception

Los sistemas de radio cognitivos son una solución a la deficiente distribución del espectro inalámbrico de frecuencias. Usando acceso dinámico al medio, los usuarios secundarios pueden comunicarse en canales de frecuencia disponibles, mientras los usuarios asignados no están usando dichos canales. Un buen sistema de mensajería de control es necesario para que los usuarios secundarios no interfieran con los usuarios primarios en las redes de radio cognitivas. Para redes en donde los usuarios son heterogéneos en frecuencia, es decir, no poseen los mismos canales de frecuencia para comunicarse, el grupo de canales utilizado para transmitir información de control debe elegirse cuidadosamente. Por esta razón, en esta tesis se estudian las ideas básicas de los esquemas de mensajería de control usados en las redes de radio cognitivas y se presenta un esquema adecuado para un control adecuado para usuarios heterogéneos en canales de frecuencia. Para ello, primero se presenta una nueva taxonomía para clasificar las estrategias de mensajería de control, identificando las principales características que debe cumplir un esquema de control para sistemas heterogéneos en frecuencia. Luego, se revisan diversas técnicas matemáticas para escoger el mínimo número de canales por los cuales se transmite la información de control. Después, se introduce un modelo de un esquema de mensajería de control que use el mínimo número de canales y que utilice las características de los sistemas heterogéneos en frecuencia. Por último, se comparan diversos esquemas de mensajería de control en términos de la eficiencia de transmisión.

Factors associated with chronic pain in patients with bipolar depression: a cross-sectional study.

BACKGROUND While pain is frequently associated with unipolar depression, few studies have investigated the link between pain and bipolar depression. In the present study we estimated the prevalence and characteristics of pain among patients with bipolar depression treated by psychiatrists in their regular clinical practice. The study was designed to identify factors associated with the manifestation of pain in these patients. METHODS Patients diagnosed with bipolar disorder (n=121) were selected to participate in a cross-sectional study in which DSM-IV-TR criteria were employed to identify depressive episodes. The patients were asked to describe any pain experienced during the study, and in the 6 weeks beforehand, by means of a Visual Analogical Scale (VAS). RESULTS Over half of the bipolar depressed patients (51.2%, 95% CI: 41.9%-60.6%), and 2/3 of the female experienced concomitant pain. The pain was of moderate to severe intensity and prolonged duration, and it occurred at multiple sites, significantly limiting the patient's everyday activities. The most important factors associated with the presence of pain were older age, sleep disorders and delayed diagnosis of bipolar disorder. CONCLUSIONS Chronic pain is common in bipolar depressed patients, and it is related to sleep disorders and delayed diagnosis of their disorder. More attention should be paid to study the presence of pain in bipolar depressed patients, in order to achieve more accurate diagnoses and to provide better treatment options.

The European Union Perception of Cuba: From Frustation to Irritation

On Friday May 16, the Ministry of Foreign Affairs of Cuba summoned the newly-appointed charged’affairs of the European Commission in Havana and announced the withdrawal of the application procedure for membership in the Cotonou Agreement of the Africa, Caribbean, and Pacific (ACP) countries, and in fact renouncing to benefit from European development aid.1 In a blistering note published in the Granma official newspaper of the Cuban Communist Party, the government blamed the EU Commission for exerting undue pressure, its alleged alignment with the policies of the United States, and censure for the measures taken by Cuba during the previous weeks.2 In reality, Cuba avoided an embarrasin flat rejection for its application. This was the anti-climatic ending for a long process that can be traced back to the end of the Cold War, in a context where Cuba has been testing alternative grounds to substitute for the overwhelming protection of the Soviet Union

Efficacy and safety of acupuncture for the treatment of non-specific acute low back pain: a randomised controlled multicentre trial protocol [ISRCTN65814467]

BACKGROUND Low back pain and its associated incapacitating effects constitute an important healthcare and socioeconomic problem, as well as being one of the main causes of disability among adults of working age. The prevalence of non-specific low back pain is very high among the general population, and 60-70% of adults are believed to have suffered this problem at some time. Nevertheless, few randomised clinical trials have been made of the efficacy and efficiency of acupuncture with respect to acute low back pain. The present study is intended to assess the efficacy of acupuncture for acute low back pain in terms of the improvement reported on the Roland Morris Questionnaire (RMQ) on low back pain incapacity, to estimate the specific and non-specific effects produced by the technique, and to carry out a cost-effectiveness analysis. METHODS/DESIGN Randomised four-branch controlled multicentre prospective study made to compare semi-standardised real acupuncture, sham acupuncture (acupuncture at non-specific points), placebo acupuncture and conventional treatment. The patients are blinded to the real, sham and placebo acupuncture treatments. Patients in the sample present symptoms of non specific acute low back pain, with a case history of 2 weeks or less, and will be selected from working-age patients, whether in paid employment or not, referred by General Practitioners from Primary Healthcare Clinics to the four clinics participating in this study. In order to assess the primary and secondary result measures, the patients will be requested to fill in a questionnaire before the randomisation and again at 3, 12 and 48 weeks after starting the treatment. The primary result measure will be the clinical relevant improvement (CRI) at 3 weeks after randomisation. We define CRI as a reduction of 35% or more in the RMQ results. DISCUSSION This study is intended to obtain further evidence on the effectiveness of acupuncture on acute low back pain and to isolate the specific and non-specific effects of the treatment.

The appropriate use of neurostimulation of the spinal cord and peripheral nervous system for the treatment of chronic pain and ischemic diseases: the neuromodulation appropriateness consensus committee.

INTRODUCTION: The Neuromodulation Appropriateness Consensus Committee (NACC) of the International Neuromodulation Society (INS) evaluated evidence regarding the safety and efficacy of neurostimulation to treat chronic pain, chronic critical limb ischemia, and refractory angina and recommended appropriate clinical applications. METHODS: The NACC used literature reviews, expert opinion, clinical experience, and individual research. Authors consulted the Practice Parameters for the Use of Spinal Cord Stimulation in the Treatment of Neuropathic Pain (2006), systematic reviews (1984 to 2013), and prospective and randomized controlled trials (2005 to 2013) identified through PubMed, EMBASE, and Google Scholar. RESULTS: Neurostimulation is relatively safe because of its minimally invasive and reversible characteristics. Comparison with medical management is difficult, as patients considered for neurostimulation have failed conservative management. Unlike alternative therapies, neurostimulation is not associated with medication-related side effects and has enduring effect. Device-related complications are not uncommon; however, the incidence is becoming less frequent as technology progresses and surgical skills improve. Randomized controlled studies support the efficacy of spinal cord stimulation in treating failed back surgery syndrome and complex regional pain syndrome. Similar studies of neurostimulation for peripheral neuropathic pain, postamputation pain, postherpetic neuralgia, and other causes of nerve injury are needed. International guidelines recommend spinal cord stimulation to treat refractory angina; other indications, such as congestive heart failure, are being investigated. CONCLUSIONS: Appropriate neurostimulation is safe and effective in some chronic pain conditions. Technological refinements and clinical evidence will continue to expand its use. The NACC seeks to facilitate the efficacy and safety of neurostimulation.

Undertreatment of acute pain (oligoanalgesia) and medical practice variation in prehospital analgesia of adult trauma patients: a 10 yr retrospective study.

BACKGROUND: Prehospital oligoanalgesia is prevalent among trauma victims, even when the emergency medical services team includes a physician. We investigated if not only patients' characteristics but physicians' practice variations contributed to prehospital oligoanalgesia. METHODS: Patient records of conscious adult trauma victims transported by our air rescue helicopter service over 10 yr were reviewed retrospectively. Oligoanalgesia was defined as a numeric rating scale (NRS) >3 at hospital admission. Multilevel logistic regression analysis was used to predict oligoanalgesia, accounting first for patient case-mix, and then physician-level clustering. The intraclass correlation was expressed as the median odds ratio (MOR). RESULTS: A total of 1202 patients and 77 physicians were included in the study. NRS at the scene was 6.9 (1.9). The prevalence of oligoanalgesia was 43%. Physicians had a median of 5.7 yr (inter-quartile range: 4.2-7.5) of post-graduate training and 27% were female. In our multilevel analysis, significant predictors of oligoanalgesia were: no analgesia [odds ratio (OR) 8.8], National Advisory Committee for Aeronautics V on site (OR 4.4), NRS on site (OR 1.5 per additional NRS unit >4), female physician (OR 2.0), and years of post-graduate experience [>4.0 to ≤5.0 (OR 1.3), >3.0 to ≤4.0 (OR 1.6), >2.0 to ≤3.0 (OR 2.6), and ≤2.0 yr (OR 16.7)]. The MOR was 2.6, and was statistically significant. CONCLUSIONS: Physicians' practice variations contributed to oligoanalgesia, a factor often overlooked in analyses of prehospital pain management. Further exploration of the sources of these variations may provide innovative targets for quality improvement programmes to achieve consistent pain relief for trauma victims.

Douteurs thoraciques en médecine ambulatoire. Sans oublier les patients qui n'ont "rien au coeur" [Thoracic pain in primary care. Don't forget the patients without heart disease].

Thoracic pain in primary care. Don't forget the patients without heart disease Thoracic pain is a frequent medical complaint. Diagnostic and therapeutic guidelines have been developed and evaluated mostly in emergency and hospital settings. The primary care practitioner, as the emergency room doctor, has to identify quickly any severe condition needing urgent and highly specialized treatment. But in primary care, the process is not finished then! A patient with no vital and urgent problem still needs a diagnosis, information and adequate treatment. This review goes over the presentation of thoracic pain, the differential diagnoses and the challenge of treating such patients in ambulatory care.
