Outpatient Quick Diagnosis Units for the evaluation of suspected severe diseases: an observational, descriptive study

Background: Hospitals in countries with public health systems have recently adopted organizational changes to improve efficiency and resource allocation, and reducing inappropriate hospitalizations has been established as an important goal. AIMS: Our goal was to describe the functioning of a Quick Diagnosis Unit in a Spanish public university hospital after evaluating 1,000 consecutive patients. We also aimed to ascertain the degree of satisfaction among Quick Diagnosis Unit patients and the costs of the model compared to conventional hospitalization practices. DESIGN: Observational, descriptive study. METHODS: Our sample comprised 1,000 patients evaluated between November 2008 and January 2010 in the Quick Diagnosis Unit of a tertiary university public hospital in Barcelona. Included patients were those who had potentially severe diseases and would normally require hospital admission for diagnosis but whose general condition allowed outpatient treatment. We analyzed several variables, including time to diagnosis, final diagnoses and hospitalizations avoided, and we also investigated the mean cost (as compared to conventional hospitalization) and the patients' satisfaction. RESULTS: In 88% of cases, the reasons for consultation were anemia, anorexia-cachexia syndrome, febrile syndrome, adenopathies, abdominal pain, chronic diarrhea and lung abnormalities. The most frequent diagnoses were cancer (18.8%; mainly colon cancer and lymphoma) and Iron-deficiency anemia (18%). The mean time to diagnosis was 9.2 days (range 1 to 19 days). An estimated 12.5 admissions/day in a one-year period (in the internal medicine department) were avoided. In a subgroup analysis, the mean cost per process (admission-discharge) for a conventional hospitalization was 3,416.13 Euros, while it was 735.65 Euros in the Quick Diagnosis Unit. Patients expressed a high degree of satisfaction with Quick Diagnosis Unit care. CONCLUSIONS: Quick Diagnosis Units represent a useful and cost-saving model for the diagnostic study of patients with potentially severe diseases. Future randomized study designs involving comparisons between controls and intervention groups would help elucidate the usefulness of Quick Diagnosis Units as an alternative to conventional hospitalization.

Relating severe poverty and chronic poverty

The severely poor are very poor since their consumption is far below the absolute poverty line, and the chronically poor are very poor since their consumption persists for long periods below the absolute poverty line. A combination of chronic poverty and severe poverty (CSP) must represent the very worst instance of poverty. Yet the exercise in this paper of asking simple questions about CSP shows large research gaps. Quantified statements on CSP at the country level can be made for just 14 countries, and at the household level in just six countries. This data suggests a positive correlation between severe poverty and chronic poverty, both at the country level and the household level. Understanding the CSP relationship – whether it is strong, where it arises, what causes it – may improve our explanation of observed cross-country variation in the elasticity between macroeconomic growth and poverty reduction, and why within countries, some households take better advantage of opportunities afforded by macroeconomic growth. Some limited data suggests similarity in socioeconomic characteristics of the severe poor and the chronic poor in terms of location, household size, gender, education and economic sector of work. Of concern is that microlongitudinal datasets drop large proportions of their base year samples, and how this affects our understanding of CSP is not well evaluated. On causal mechanisms, evidence suggests that CSP may be caused by parental CSP (i.e. an intergenerational CSP cycle) and in households not previously poor, CSP may be caused by a morbidity cycle.

Anemia en la enfermedad inflamatoria intestinal: Prevalencia y factores que influyen.

La anemia es una complicación muy importante de la enfermedad inflamatoria intestinal (EII). Actualmente desconocemos la prevalencia de anemia en los pacientes afectos por dicha enfermedad. Para ello se ha realizado un estudio retrospectivo de revisión del historial clínico de pacientes con EII registrados en la Unidad de Atención Crohn-Colitis, con el objetivo de determinar la prevalencia de anemia en nuestro medio y analizar los factores que influyen en la aparición de la misma. La prevalencia de anemia en la EII en el año 2007 fue del 26,3%. El factor más importante para desarrollarla fue la presencia de actividad clínica.

Anemia en pacientes de edad avanzada con insuficiencia cardíaca ingresados en un servicio de medicina interna

Introducción: la anemia es una entidad muy prevalente en pacientes con insuficiencia cardíaca (IC) y se asocia a mayor morbimortalidad. Objetivos: analizar las comorbilidades de pacientes hospitalizados de ≥ 65 años con IC. Estudiar el impacto de la anemia sobre esta población y comparar esta comorbilidad respecto a aquéllos que no la presentan en relación a la valoración geriátrica integral (VGI), así como la adecuación del tratamiento farmacológico en la IC. Pacientes y métodos: estudio descriptivo observacional transversal de una cohorte de 150 pacientes ingresados en el Servicio de Medicina Interna del Hospital Vall d’Hebron, entre junio de 2007 y enero de 2010, mediante entrevista clínica y recogida de datos de la historia clínica. Resultados: en la muestra prevalecían las mujeres (62%), los pacientes con hipertensión (84%), los que tenían la FEVI conservada (66,4%) y los pacientes con anemia (61,3%), de los cuales el 60,9% presentaban anemia inflamatoria y el 35,9% anemia ferropénica. Los pacientes con anemia tuvieron peor valor de MNA (p=0,017, con un RR de 2,7), mayor diferencial de Barthel (p=0,021) y peor valor de albuminemia (p=0,001). Asimismo, se observó que 53 pacientes con indicación según las guías clínicas de tratamiento con IECA o ARA II no lo seguían, y hasta 105 pacientes en el caso de los betabloqueantes (BB). Conclusiones: los pacientes con anemia presentaban pero estado nutricional, y mayor empeoramiento del índice de Barthel. Respecto al tratamiento de la IC, destacaba el gran número de pacientes sin tratamiento con IECA, ARA II o BB, que deberían llevarlo según las guías de práctica clínica.

Long-term azithromycin therapy in patients with severe chronic obstructive pulmonary disease and repeated pulmonary exacerbations

L’objectiu es determinar si el tractament amb azitromicina a llarg termini redueix la freqüència d’exacerbacions respiratòries en pacients amb malaltia pulmonar obstructiva crònica (MPOC) greu. Estudi retrospectiu observacional que avalua els beneficis clínics del tractament amb azitromicina a llarg termini (500 mg per via oral tres vegades per setmana) durant 12 mesos en pacients amb MPOC greu amb un mínim de 4 exacerbacions agudes (EAMPOC) per any o colonitzats per Pseudomonas aeruginosa. Es comparen amb els 12 mesos previs a l’introducció de l’azitromicina: nombre de EAMPOC, hospitalitzacions i dies d'estada hospitalària. L’azitromicina a llarg termini s’associa a una reducció significativa de EAMPOC, hospitalitzacions i dies d’estada hospitalària en pacients amb EPOC greu independentment de la colonització basal.

Estudio retrospectivo de la influencia de la respuesta al tratamiento quimioterápico de primera línea en pacientes con cáncer no microcítico de pulmón sobre la respuesta a la administración de factores estimulantes de la eritropoyesis en la anemia inducida por quimioterapia

S’analitza de manera retrospectiva la relació entre la resposta a la quimioteràpia i la milloria de l’anèmia induïda per la quimioteràpia amb factors estimulants de la eritropoesi en 57 pacients amb carcinoma no microcític de pulmó avançat que presentaren anèmia durant el tractament amb quimioteràpia. Els pacients amb progressió desenvoluparen anèmia significativament abans que els responedors y presentaren de forma significativa una menor tassa de resposta al tractament amb factors estimulants de la eritropoesi. La resposta a la quimioteràpia té un impacte directe en la efectivitat del tractament de la anèmia amb factors estimulant de la eritropoesi. Aquesta correlació pot valdre com marcador subrogat de resposta a la quimioteràpia. Paraules clau: Càncer no microcític de pulmó, anèmia induïda per quimioteràpia, factors estimulants de la eritropoesi, factor predictor de resposta

Papel del hierro endovenoso para el manejo de la anemia preoperatoria en cirugía ortopédica mayor dentro de un programa de ahorro de sangre

Objetivos La anemia preoperatoria es frecuente en cirugía ortopédica mayor y es un factor predictivo de transfusión y de peor evolución postoperatoria. El objetivo de este estudio es evaluar la utilidad y seguridad del hierro endovenoso como tratamiento de la anemia preoperatoria y ferropenia en cirugía ortopédica mayor, y valorar la respuesta según el hierro utilizado y/o el tipo de anemia de acuerdo con el algoritmo de actuación de nuestro programa de ahorro de sangre. Material y métodos Análisis retrospectivo de una base de datos prospectiva de los pacientes programados para prótesis total de cadera (PTC) y de rodilla (PTR), en los últimos 5 años. Utilizamos la base de datos online PAS (Programa de Ahorro de Sangre) en www.awge.org que incluye: edad, sexo, peso, ASA, metabolismo del hierro, evolución de la hemoglobina (Hb), efectos adversos y transfusión. Resultados Se incluyeron en el PAS 3.488 pacientes de los cuales 612 (17,5%) presentaban anemia preoperatoria y 169 (27,6%) fueron tratados con hierro endovenoso (HE) De los pacientes tratados con HE (169), 35 recibieron hierro sacarosa (HS) y 134 hierro carboximaltosa (HCM). De acuerdo con el algoritmo de tratamiento, 101 lo recibieron por anemia por déficit de hierro (ADH), 26 por ferropenia sin anemia (DH), 21 por anemia de proceso crónico (APC) y 21 en otros tipos de anemia. El incremento de la Hb fue de 1 ± 09 g/dl en el DH, de 1.7± 1 g/dl en ADH y de 2.1 ± 1 g/dl en APC y otras anemias (P<0.001). El grupo del HCM la adherencia al tratamiento fue superior y necesitaron menos visitas (p<0.001). Los efectos adversos fueron leves y similares en ambos grupos. Conclusiones El hierro endovenoso (HS o HCM) es un tratamiento eficaz y seguro de la anemia preoperatoria en cirugia ortopédica mayor, aunque el HCM tiene la ventaja de conseguir el mismo resultado con sólo una administración.

Disease-corrected haematopoietic progenitors from Fanconi anemia induced pluripotent stem cells

The generation of induced pluripotent stem (iPS) cells has enabled the derivation of patient-specific pluripotent cells andprovided valuable experimental platforms to model human disease. Patient-specific iPS cells are also thought to hold greattherapeutic potential, although direct evidence for this is still lacking. Here we show that, on correction of the genetic defect,somatic cells from Fanconi anaemia patients can be reprogrammed to pluripotency to generate patient-specific iPS cells. These cell lines appear indistinguishable from human embryonic stem cells and iPS cells from healthy individuals. Most importantly, we show that corrected Fanconi-anaemia-specific iPS cells can give rise to haematopoietic progenitors of the myeloid and erythroid lineages that are phenotypically normal, that is, disease-free. These data offer proof-of-concept that iPS cell technology can be used for the generation of disease-corrected, patient-specific cells with potential value for cell therapy applications.

Predictive ability of severe rainfall events over Catalonia for the year 2008

This paper analyses the predictive ability of quantitative precipitation forecasts (QPF) and the so-called "poor-man" rainfall probabilistic forecasts (RPF). With this aim, the full set of warnings issued by the Meteorological Service of Catalonia (SMC) for potentially-dangerous events due to severe precipitation has been analysed for the year 2008. For each of the 37 warnings, the QPFs obtained from the limited-area model MM5 have been verified against hourly precipitation data provided by the rain gauge network covering Catalonia (NE of Spain), managed by SMC. For a group of five selected case studies, a QPF comparison has been undertaken between the MM5 and COSMO-I7 limited-area models. Although MM5's predictive ability has been examined for these five cases by making use of satellite data, this paper only shows in detail the heavy precipitation event on the 9¿10 May 2008. Finally, the "poor-man" rainfall probabilistic forecasts (RPF) issued by SMC at regional scale have also been tested against hourly precipitation observations. Verification results show that for long events (>24 h) MM5 tends to overestimate total precipitation, whereas for short events (¿24 h) the model tends instead to underestimate precipitation. The analysis of the five case studies concludes that most of MM5's QPF errors are mainly triggered by very poor representation of some of its cloud microphysical species, particularly the cloud liquid water and, to a lesser degree, the water vapor. The models' performance comparison demonstrates that MM5 and COSMO-I7 are on the same level of QPF skill, at least for the intense-rainfall events dealt with in the five case studies, whilst the warnings based on RPF issued by SMC have proven fairly correct when tested against hourly observed precipitation for 6-h intervals and at a small region scale. Throughout this study, we have only dealt with (SMC-issued) warning episodes in order to analyse deterministic (MM5 and COSMO-I7) and probabilistic (SMC) rainfall forecasts; therefore we have not taken into account those episodes that might (or might not) have been missed by the official SMC warnings. Therefore, whenever we talk about "misses", it is always in relation to the deterministic LAMs' QPFs.

Impacts on the deep-sea ecosystem by a severe coastal storm

Major coastal storms, associated with strong winds, high waves and intensified currents, and occasionally with heavy rains and flash floods, are mostly known because of the serious damage they can cause along the shoreline and the threats they pose to navigation. However, there is a profound lack of knowledge on the deep-sea impacts of severe coastal storms. Concurrent measurements of key parameters along the coast and in the deep-sea are extremely rare. Here we present a unique data set showing how one of the most extreme coastal storms of the last decades lashing the Western Mediterranean Sea rapidly impacted the deep-sea ecosystem. The storm peaked the 26th of December 2008 leading to the remobilization of a shallow-water reservoir of marine organic carbon associated with fine particles and resulting in its redistribution across the deep basin. The storm also initiated the movement of large amounts of coarse shelf sediment, which abraded and buried benthic communities. Our findings demonstrate, first, that severe coastal storms are highly efficient in transporting organic carbon from shallow water to deep water, thus contributing to its sequestration and, second, that natural, intermittent atmospheric drivers sensitive to global climate change have the potential to tremendously impact the largest and least known ecosystem on Earth, the deep-sea ecosystem.

Oscar Wilde. De profundis: a severe judgement of Sophocles as a poet

O. Wilde considers that Christ ranks with the poets and Shelley and Sophocles are of his company. Nevertheless, the result of this comparison becomes unfavourable as far Sophocles is concerned, who, precisely as a poet can reach neither the sublimity nor the real tragic sufferance which Christ symbolises. According to Wilde, Christ is both a poet and a tragic poem, while Sophocles is merely a poet, thus being certified the impossibility of the above mentioned comparison.

Oscar Wilde. 'Camma', a severe and hedonic aesthetic correction of Plutarch's ethics

The aim of this article is to present an accurate analysis of O. Wilde's poem 'Camma' by referring it to its Greek model: that Camma both in Plutarch's Amatorius (Eroticus) and Mulierum Virtutes. It is precisely this accurate reading which permits us to verify how Plutarch's Ethics is corrected from the parameters of the hedonism which is peculiar to O. Wilde's aestheticism, thus turning Camma into a symbol of a pleasant life.

Family impact in intellectual disability, severe mental health disorders and mental health disorders in ID. A comparison

Family impact (or family burden) is a concept born in the field of mental health that has successfully been exported to the ambit of intellectual disability (ID). However, differences in family impact associated with severe mental health disorders (schizophrenia), to ID or to mental health problems in ID should be expected. Seventy-two adults with intellectual disability clients of the Carmen Pardo-Valcarce Foundation's sheltered workshops and vocational employment programmes in Madrid (Spain), 203 adults diagnosed with schizophrenia from four Spanish Community Mental Health Services (Barcelona, Madrid, Granada and Navarra) and 90 adults with mental health problems in ID (MH-ID) from the Parc Sanitari Sant Joan de Déu Health Care Site in Sant Boi de Llobregat, Barcelona (Spain) were asked to participate in the present study along with their main caregivers. Family impact experienced by caregivers was assessed with the ECFOS-II/SOFBI-II scale (Entrevista de Carga Familiar Objetiva y Subjetiva/Objective and Subjective Family Burden Interview). In global terms, results showed that the higher family impact was found between caregivers to people with MH-ID. The interaction of both conditions (ID and mental health problems) results in a higher degree of burden on families than when both conditions are presented separately. There was also an impact in caregivers to people with schizophrenia, this impact being higher than the one detected in caregivers to people with intellectual disability. Needs of caregivers to people with disability should be addressed specifically in order to effectively support families.

Association of MMP-2 polymorphisms with severe and very severe COPD: a case control study of MMPs-1, 9 and 12 in a European population.

BACKGROUND: Genetic factors play a role in chronic obstructive pulmonary disease (COPD) but are poorly understood. A number of candidate genes have been proposed on the basis of the pathogenesis of COPD. These include the matrix metalloproteinase (MMP) genes which play a role in tissue remodelling and fit in with the protease--antiprotease imbalance theory for the cause of COPD. Previous genetic studies of MMPs in COPD have had inadequate coverage of the genes, and have reported conflicting associations of both single nucleotide polymorphisms (SNPs) and SNP haplotypes, plausibly due to under-powered studies. METHODS: To address these issues we genotyped 26 SNPs, providing comprehensive coverage of reported SNP variation, in MMPs- 1, 9 and 12 from 977 COPD patients and 876 non-diseased smokers of European descent and evaluated their association with disease singly and in haplotype combinations. We used logistic regression to adjust for age, gender, centre and smoking history. RESULTS: Haplotypes of two SNPs in MMP-12 (rs652438 and rs2276109), showed an association with severe/very severe disease, corresponding to GOLD Stages III and IV. CONCLUSIONS: Those with the common A-A haplotype for these two SNPs were at greater risk of developing severe/very severe disease (p = 0.0039) while possession of the minor G variants at either SNP locus had a protective effect (adjusted odds ratio of 0.76; 95% CI 0.61 - 0.94). The A-A haplotype was also associated with significantly lower predicted FEV1 (42.62% versus 44.79%; p = 0.0129). This implicates haplotypes of MMP-12 as modifiers of disease severity.
