Cambios en el tratamiento y disminución de la mortalidad del síndrome aórtico agudo. Lecciones del Registro Español del Síndrome Aórtico Agudo (RESA) / Spanish Registry of Acute Aortic Syndrome (RESA). Changes in therapeutic management and lower mortality in acute aortic syndrome

Introducción y objetivos El Registro Español del Síndrome Aórtico Agudo (RESA) se inició en 2005 para valorar las características del síndrome aórtico agudo (SAA) en nuestro país. El objetivo es analizar las diferencias en las características, el abordaje y el tratamiento y la mortalidad observadas entre las 3 ediciones del RESA. Métodos Se analizaron los datos de los pacientes con SAA incluidos prospectivamente por 24-30 hospitales terciarios en las 3 ediciones: RESA I (2005-2006), RESA II (2012-2013) y RESA III (2018-2019). Resultados Se incluyó a 1.902 pacientes (el 74% varones; media de edad, 60,7± 12,5 años), 1.329 (69,9%) tipo A y 573 (30,1%) tipo B. Comparando los RESAS, la tomografía computarizada aumentó como técnica diagnóstica (el 77,1, el 77,9 y el 84,2% respectivamente; p=0,001). El tratamiento quirúrgico del SAA tipo A aumentó (el 79,6, el 78,7 y el 84,5%; p=0,045) y la mortalidad total disminuyó (el 41,2, el 34,5 y el 31,2%; p=0,002), coincidiendo con una reducción de la mortalidad quirúrgica (el 33,4, el 25,1 y el 23,9%; p=0,003). En el tipo B, el tratamiento endovascular aumentó (el 22,8, el 32,8 y el 38,7%; p=0,006). La mortalidad total del SAA tipo B disminuyó (el 21,6, el 16,1 y el 12,0%; p=0,005) como consecuencia de la reducción de la mortalidad de los tratamientos médico (el 16,8, el 13,8 y el 8,8%; p=0,030) y endovascular (el 27,0, el 18,0 y el 9,2%; p=0,009). Conclusiones El RESA evidencia una disminución de la mortalidad del SAA tipo A coincidiendo con un incremento del tratamiento quirúrgico y una reducción de su mortalidad. En el SAA tipo B, el tratamiento endovascular se asocia con un aumento de la supervivencia, ya que permite una mejor estrategia terapéutica para los pacientes con complicaciones (AU)

Introduction and objectives The Spanish Registry of Acute Aortic Syndrome (RESA) was launched in 2005 to identify the characteristics of acute aortic syndrome (AAS) in Spain. The aim of this study was to analyze the differences in management and mortality in the 3 RESA iterations. Method We analyzed data from patients with AAS prospectively included by 24 to 30 tertiary centers during the 3 iterations of the registry: RESA I (2005-2006), RESA-II (2012-2013), and RESA III (2018-2019). Result AAS was diagnosed in 1902 patients (74% men; age, 60.7±12.5 years): 1329 (69.9%) type A and 573 (30.1%) type B. Comparison of the 3 periods revealed that the use of computed tomography increased as the first diagnostic technique (77.1%, 77.9%, and 84.2%, respectively; P=.001). In type A, surgical management increased (79.6%, 78.7%, and 84.5%; P=.045) and overall mortality decreased (41.2%, 34.5%, and 31.2%; P=.002), due to a reduction in surgical mortality (33.4%, 25.1%, and 23.9%; P=.003). In type B, endovascular treatment increased (22.8%, 32.8%, and 38.7%; P=.006), while medical and surgical treatment decreased. Overall type B mortality also decreased (21.6%, 16.1%, and 12.0%; P=.005) in line with a reduction in mortality with medical (16.8%, 13.8%, and 8.8%, P=.030) and endovascular (27.0%, 18.0%, and 9.2%; P=.009) treatments. Conclusion The iterations of RESA show a decrease in mortality from type A AAS, coinciding with an increase in surgical treatment and a reduction in surgical mortality. In type B, the use of endovascular treatment was associated with improved survival, allowing better management in patients with complications (AU)

Oral and oropharyngeal squamous cell carcinoma in young adults: A retrospective study in Granada University Hospital.

BACKGROUND: This study aims to evaluate and analyze the clinical features and outcomes of oral and oropharyngeal squamous cell carcinoma (SCC) in patients < 45-years old in our center. MATERIAL AND METHODS: A retrospective analysis was conducted using the records of patients diagnosed with oral and oropharyngeal SCC between 1998 and 2011 in the University Hospital of Granada (Spain). The analysis identified 33 patients with oral and oropharyngeal SCC with an age of <45 years. Moreover, during the years studied, a further 472 patients were diagnosed with oral and oropharyngeal SCC in our center. Thus, 100 SCC patients with an age of >45 years were randomly selected from the same database. A retrospective analysis was conducted to determine specific features including sites of occurrence, risk factors, sex distribution, socio-economic status, T stage at diagnosis, nodal involvement, degree of tumor differentiation, locoregional failure and overall survival at 5 years was. Further, the results of both groups were compared. RESULTS: The male-female ratio was 1.2:1 in the group of young adults and 2.03:1 in the group of patients with an age of >45 years. No significant differences were found in terms of site, nodal involvement, locoregional failure, and overall survival. However, there were statistically significant differences between the two groups in terms of features such as risk factors, socio-economic status, T stage at diagnosis, and degree of tumor differentiation. The overall 5-year survival rate was 62% for patients >45 years old, whilst for the group of young adults this rate was 48.4% (p= 0.17). CONCLUSIONS: The poor association between the common risk factors and oral and oropharyngeal cancers in young adults suggests that other pathogenic mechanisms should be investigated. For young patients, the data show evidence of poorer outcomes in terms of overall survival (p=0.17), and locoregional failure (p=0.23). Nevertheless, the literature shows that the results in this field are particularly inconsistent, and further research is therefore needed to provide more in-depth knowledge of the disease in this age group.

Prevalence of peripheral artery disease (PAD) and factors associated: An epidemiological analysis from the population-based Screening PRE-diabetes and type 2 DIAbetes (SPREDIA-2) study.

AIM: To describe the prevalence of Peripheral Artery Disease (PAD) in a random population sample and to evaluate its relationship with Mediterranean diet and with other potential cardiovascular risk factors such as serum uric acid and pulse pressure in individuals ranged 45 to 74 years. METHODS: Cross-sectional analysis of 1568 subjects (mean age 6.5 years, 43% males), randomly selected from the population. A fasting blood sample was obtained to determine glucose, lipids, and HbA1C levels. An oral glucose tolerance test was performed in non-diabetic subjects. PAD was evaluated by ankle-brachial index and/or having a prior diagnosis. RESULTS: PAD prevalence was 3.81% (95% CI, 2.97-4.87) for all participants. In men, PAD prevalence was significantly higher than in women [5.17% (95% CI, 3.74-7.11) vs. 2.78% (95% CI, 1.89-4.07); p = 0.014]. Serum uric acid in the upper quartile was associated with the highest odds ratio (OR) of PAD (for uric acid > 6.1 mg/dl, OR = 4.31; 95% CI, 1.49-12.44). The remaining variables more strongly associated with PAD were: Heart rate >90 bpm (OR = 4.16; 95%CI, 1.62-10.65), pulse pressure in the upper quartile (≥ 54 mmHg) (OR = 3.82; 95%CI, 1.50-9.71), adherence to Mediterranean diet (OR = 2.73; 95% CI, 1.48-5.04), and former smoker status (OR = 2.04; 95%CI, 1.00-4.16). CONCLUSIONS: Our results show the existence of a low prevalence of peripheral artery disease in a population aged 45-74 years. Serum uric acid, pulse pressure and heart rate >90 bpm were strongly associated with peripheral artery disease. The direct association between Mediterranean diet and peripheral artery disease that we have found should be evaluated through a follow-up study under clinical practice conditions.

Real-life data in 115 chronic migraine patients treated with Onabotulinumtoxin A during more than one year.

BACKGROUND: OnabotulinumtoxinA (OnabotA) is effective in Chronic Migraine (CM) during first year of treatment and longer. In real clinical setting, CM patients with acute Medication Overuse (MO) or concurrently receiving oral preventatives are treated with OnabotA. We aim to assess evolution of CM patients beyond first year on OnabotA. METHODS: Data were retrospectively collected in three headache units. We analyzed cases who had received at least five sessions of OnabotA according to PREEMPT protocol. We continued OnabotA therapy when a reduction of number of headache days of at least 30% was achieved. RESULTS: We included 115 patients (98 females, 17 males) who completed 7.6 ± 2.3 (5-13) OnabotA procedures. Previously they had not responded to topiramate and, at least, one other preventative. Age at inclusion was 45.3 ± 12 (14-74) years, and latency between CM onset and OnabotA therapy was 43.1 ± 38.2 (6-166) months. At first OnabotA session 92 patients (80%) fulfilled MO criteria and 107 (93%) received a concurrent oral preventative. In 42 cases (36.5%) OnabotA dose was increased over 155 units. After first year in 57 out of 92 patients (61.9%) MO was discontinued. Among those receiving preventatives, in 52 out of 107 they were retired (48.6%). In 22 cases (19.1%) OnabotA administration was delayed to the fourth or fifth month and in 12 (10.4%) it was temporally stopped. Finally, in 18 patients (15.7%) OnabotA was discontinued due to lack of efficacy beyond first year of treatment. CONCLUSION: Our results suggest that discontinuation of acute medication overuse and oral preventive therapies are achievable objectives in long-term using of OnabotA in CM patients.

Performance of the Finnish Diabetes Risk Score and a Simplified Finnish Diabetes Risk Score in a Community-Based, Cross-Sectional Programme for Screening of Undiagnosed Type 2 Diabetes Mellitus and Dysglycaemia in Madrid, Spain: The SPREDIA-2 Study.

AIM: To evaluate the performance of the Finnish Diabetes Risk Score (FINDRISC) and a simplified FINDRISC score (MADRISC) in screening for undiagnosed type 2 diabetes mellitus (UT2DM) and dysglycaemia. METHODS: A population-based, cross-sectional, descriptive study was carried out with participants with UT2DM, ranged between 45-74 years and lived in two districts in the north of metropolitan Madrid (Spain). The FINDRISC and MADRISC scores were evaluated using the area under the receiver operating characteristic curve method (ROC-AUC). Four different gold standards were used for UT2DM and any dysglycaemia, as follows: fasting plasma glucose (FPG), oral glucose tolerance test (OGTT), HbA1c, and OGTT or HbA1c. Dysglycaemia and UT2DM were defined according to American Diabetes Association criteria. RESULTS: The study population comprised 1,426 participants (832 females and 594 males) with a mean age of 62 years (SD = 6.1). When HbA1c or OGTT criteria were used, the prevalence of UT2DM was 7.4% (10.4% in men and 5.2% in women; p<0.01) and the FINDRISC ROC-AUC for UT2DM was 0.72 (95% CI, 0.69-0.74). The optimal cut-off point was ≥13 (sensitivity = 63.8%, specificity = 65.1%). The ROC-AUC of MADRISC was 0.76 (95% CI, 0.72-0.81) with ≥13 as the optimal cut-off point (sensitivity = 84.8%, specificity = 54.6%). FINDRISC score ≥12 for detecting any dysglycaemia offered the best cut-off point when HbA1c alone or OGTT and HbA1c were the criteria used. CONCLUSIONS: FINDRISC proved to be a useful instrument in screening for dysglycaemia and UT2DM. In the screening of UT2DM, the simplified MADRISC performed as well as FINDRISC.

Esclerodermia y paniculitis localizadas / Localized scleroderma and panniculitis

La esclerodermia es una enfermedad del tejido conectivo, autoinmunitaria y caracterizada por fibrosis de la piel1-3. Literalmente significa 'piel dura'. La afectación puede ser mínima (solo en dedos y cara, muy lentamente progresiva) o generalizada (afectando de forma rápida a uno o más órganos internos). La paniculitis neutrofílica4,6 es una respuesta inmunitaria localizada en forma de placa o nódulo, en el seno generalmente de una enfermedad sistémica (AU)

Scleroderma is a disease that affects the connective tissue. It is an autoimmune disease and it is characterized by skin fibrosis. It literally means 'hard skin'. The involvement can be minimal (only fingers and face, progressing slowly) or generalized (quickly affecting one or two internal organs). Neutrophilic panniculitis is an immune response located in the form of a plate or nodule, generally related to a systemic disease (AU)

Síndrome metabólico en pacientes con enfermedad arterial periférica / Metabolic syndrome in patients with peripheral arterial disease

Antecedentes y objetivos. La prevalencia del síndrome metabólico (SM) en pacientes con enfermedad arterial periférica (EAP) y arteriosclerosis de otros territorios está incrementada, pero se desconoce si también lo está en pacientes con EAP aislada. En pacientes con EAP, sin otra enfermedad aterosclerótica, hemos evaluado la prevalencia del SM y el grado de control de los factores de riesgo y fármacos cardiovasculares en comparación con enfermos sin SM. Pacientes y métodos. Estudio transversal multicéntrico, subestudio del PERIFÉRICA, realizado en consultas de atención primaria y especializada en 2009. Se incluyeron 3.934 pacientes, con ≥45 años y EAP documentada mediante el índice tobillo-brazo <0,9, amputación o revascularización arterial, sin antecedentes de enfermedad coronaria y/o cerebrovascular. Resultados. La edad media fue 67,6 años y el 73,8% eran varones. La prevalencia del SM fue del 63% (IC95% 61,5-64,3%). Los pacientes con SM tenían mayor prevalencia de factores de riesgo, mayor comorbilidad, una EAP más grave y utilizaban más frecuentemente fármacos cardiovasculares. Tras ajustar por factores de riesgo y comorbilidad, los bloqueadores del sistema renina-angiotensina, betabloqueantes, diuréticos y estatinas eran los fármacos utilizados con mayor frecuencia. Los objetivos de presión arterial (22% vs. 41,5%, p<0,001) y de HbA1c en pacientes diabéticos (44% vs. 53,1%, p<0,001) se alcanzaron menos frecuentemente en los pacientes con SM que en los que no tenían esta condición, sin que hubiera diferencias en cuanto al colesterol-LDL (29,8% vs. 39,1%, p=0,265). Conclusión. Cerca de dos tercios de los pacientes con EAP padecen el SM. A pesar de utilizar más fármacos cardiovasculares los objetivos terapéuticos se alcanzan en una menor proporción que en los pacientes sin SM (AU)

Background and objective. The prevalence of metabolic syndrome (MS) in patients with peripheral arterial disease (PAD) and coronary or cerebrovascular disease is increasing, but it is not known whether this association also exists in patients with isolated PAD. The aim of the current study was to assess the prevalence of MS in patients with PAD who had no coronary or cerebrovascular disease, the prescription rate of evidence-based cardiovascular therapies and the attainment of therapeutic goals in patients with PAD and with and without MS. Patients and methods. Multicenter, cross-sectional study of 3.934 patients aged ≥ 45 years with isolated PAD who were treated in primary care and specialized outpatient clinics during 2009. A diagnosis of PAD was reached for ankle brachial indices <0.9, a previous history of amputation or revascularization. Results. In the overall population, the mean age was 67.6 years, 73.8% were males and 63% had MS (95% CI 61.5-64.3%). Patients with MS had a higher prevalence of cardiovascular risk factors and comorbidities, more severe PAD and higher prescription rate of evidence-based cardiovascular therapies. After adjusting for risk factors and comorbidity, there was a more frequent use of renin-angiotensin system blockers, beta-blockers, diuretics and statins among the patients with MS. A lower percentage of patients with MS achieved the therapeutic goals for blood pressure (22% vs. 41.5%, p<0.001). Similarly, a lower percentage of patients with diabetes achieved the glycated hemoglobin goals (44% vs. 53.1%, p<0.001), with no differences in LDL-cholesterol levels (29.8% vs. 39.1%, p=0.265). Conclusion. Patients with PAD have a high prevalence of MS. Patients with MS do not attain therapeutic goals as frequently as those without, despite taking more cardiovascular drugs (AU)

Mastocitoma solitario / Solitary mastocytoma

La mastocitosis consiste en una proliferación anormal de mastocitos en los tejidos, y el mastocitoma solitario es una de las formas más frecuentes. La evolución tiende a la curación espontánea, si bien un mínimo porcentaje de mastocitomas solitarios requieren extirpación quirúrgica (AU)

Mastocytosis is abnormal proliferation of tissue mast cells, being solitary mastocytoma the most common. Evolution tends to spontaneous healing, although a small percentage of solitary mastocytoma require surgical removal (AU)

Diagnostic accuracy of the faecal immunochemical test for colorectal cancer in symptomatic patients: comparison with NICE and SIGN referral criteria.

AIM: The diagnostic accuracy of the faecal immunochemical test (FIT) at a 100 ng/ml threshold for colorectal cancer (CRC) was compared with National Institute for Health and Care Excellence (NICE) and the Scottish Intercollegiate Guidelines Network (SIGN) referral criteria. METHOD: A multicentre, prospective, blind study of diagnostic tests was carried out in two Spanish health areas. In 787 symptomatic patients referred for a diagnostic colonoscopy, we determined whether patients met NICE and SIGN referral criteria. All patients performed one FIT determination (OCsensor(™) ). The sensitivity and specificity for CRC detection were determined with McNemar's test. The diagnostic odds ratio as well as the number needed to scope (NNS) to detect a CRC were calculated. RESULTS: We detected CRC in 97 (12.3%) patients; 241 (30.6%) had an FIT ≥ 100 ng/ml and 300 (38.1%) and 473 (60.1%) met NICE and SIGN referral criteria. The FIT had a higher sensitivity for CRC detection than NICE criteria (87.6%, 61.9%; P < 0.001) and SIGN criteria (82.5%; P = 0.4). The specificity of FIT was also higher than NICE and SIGN criteria (77.4%, 65.2%, 42.7%; P < 0.001). The odds ratios of FIT, NICE and SIGN criteria for the diagnosis of CRC were 24.24 (95% CI 12.91-45.53), 3.04 (95% CI 1.96-4.71) and 3.51 (95% CI 2.03-6.06). The NNS to detect a CRC in individuals with an FIT ≥ 100 ng/ml was 2.83 (95% CI 2.4-3.41) and in individuals who met NICE and SIGN criteria it was 5 (95% CI 3.98-6.37) and 5.95 (95% CI 4.85-7.35). CONCLUSION: Our study suggests that FIT is more accurate for the detection of CRC than the current NICE and SIGN referral criteria in symptomatic patients referred for colonoscopy.

Conducta frente a filtraciones post gastrectomía vertical / Manifestations and management of leaks after sleeve gastrectomy

Background: sleeve gastrectomy is one of the most commonly used bariatric surgical procedures. Aim: to analyze clinical and laboratory manifestations and management of leaks after sleeve gastrectomy. Material and Methods: analysis of 20 patients with leaks out of 785 operated subjects (2.5 percent). Symptoms and laboratory changes were analyzed. Leak was classified according to the postoperative day of appearance, its location and its severity. Results: fever, abdominal pain and tachycardia were the main clinical manifestations of the leak. Patients also had leukocytosis and an elevated C reactive protein. In 12 (60 percent) patients, the leak appeared within the first four postoperative days, in three, it appeared between the fifth and ninth postoperative day and in five, after the tenth postoperative day. In 90 percent, the leak was near the cardias. Eleven patients were reoperated and nine were managed conservatively. The leak closed 34 and 55 days after its appearance among patients managed conservatively or surgically, respectively. Conclusions: leaks are a serious complication of sleeve gastrectomy and require a close surveillance of patients.

Introducción: la gastrectomía vertical laparoscópica es una de las técnicas quirúrgicas más empleadas en pacientes con obesidad. El Objetivo de este trabajo es analizar los hallazgos clínicos y de laboratorio en pacientes con filtraciones post gastrectomía vertical, así como el tratamiento y la evolución clínica. Material y Método: el grupo estudiado comprende a 20 pacientes (2,5 por ciento) de un total de 785 operados. En todos se evaluó la presencia de síntomas y signos clínicos, así como el hemograma y PCR. La filtración se clasificó de acuerdo a 3 parámetros: a) día de aparición de la filtración; b) su localización; c) su gravedad. Resultados: la presencia de fiebre, dolor abdominal y taquicardia fueron los principales síntomas y signos. Leucocitosis con desviación a izquierda y PCR elevados fueron hallazgos importantes. Hubo 12 pacientes (60 por ciento) con filtración precoz, 3 pacientes (15 por ciento) con filtración de tipo intermedia y 5 pacientes (25 por ciento) con filtración tardía. El 90 por ciento era de localización alta. Se reoperaron 11 pacientes y se manejaron conservadoramente 9. El cierre de la filtración ocurrió en promedio 34 días después de la operación con manejo conservador y a los 55 días con manejo quirúrgico. No hubo mortalidad. Prótesis expansible se empleó en 4 pacientes. Conclusión: la filtración posterior a una gastrectomía vertical es un evento grave, que requiere una observación clínica muy cercana del paciente.

Incidencia de caídas en mujeres que participan periódicamente en un programa de revitalización geriátrica. Estudio con seguimiento de 5 años / Incidence of falls in women who regularly participate in a geriatric revitalitation program. A 5-year follow-up study

Introducción Las caídas constituyen uno de los síndromes más importantes en geriatría. El objetivo es conocer la incidencia de caídas durante 5 años en una población de mujeres que participan anualmente en un programa de revitalización geriátrica. Material y métodos Estudio de cohortes con seguimiento de 5 años de 137 mujeres con edades comprendidas entre los 60 y los 90 años (media ± DT: 71,65 ± 5,58 años), que participaron periódicamente en un programa de revitalización geriátrica desarrollado durante 9 meses al año. Se registran en cada periodo el número de caídas, la talla, el peso y la asistencia al programa. Se calcularon la incidencia y la tasa de caídas durante el seguimiento y el riesgo de volverse a caer. Se estudió la relación entre la edad y la asistencia al programa. Resultados Se registraron 207 caídas en 84 mujeres distintas. Incidencia de caídas a los 5 años: de 1,51 caídas/mujer. El 40% no se cayó ninguna vez en todo el periodo. El porcentaje anual de mujeres que se cayeron alguna vez varió entre el 21,2 y el 26,3%, y el de las que se cayeron 2 o más veces, entre el 0,7 y el 5%. Se registró una reducción en la tasa de caídas durante los periodos de actividad. La asistencia media osciló entre el 75 y el 83%. No se encontró relación significativa entre la asistencia ni la edad y el hecho de caerse. Conclusiones La incidencia de caídas en la población de estudio es inferior a la reportada en la literatura para el mismo segmento de la población. Los estudios que incluyen revitalización geriátrica como posible herramienta en la prevención de la discapacidad y el mantenimiento de la calidad de vida en las personas mayores son necesarios(AU)

Introduction Falls are one of the most important syndromes in geriatrics. This study has aimed to determine the incidence of falls in a 5-year period in a population of women who participate in a Geriatric Revitalization Program that is held annually. Material and methods A cohort study with a 5-year follow-up of 137 women aged 60 to 90 (mean age of 71.65 years SD 5.58) who regularly participated in a Geriatric Revitalization Program carried out 9 months a year was performed. The number of falls in each period, height, weight and the attendance to the program were recorded. Incidence and rate of falls during follow-up were calculated. The relation between age and attendance to the program were also studied. Results A total of 207 falls in 84 different women were recorded. Incidence of falls at 5 years follow-up was of 1.51 falls/women (SD 1.83). Forty percent of women did not fall during the period studied. Annual percentage of women who fell once per year ranged from 21.2% to 26.3%, and who fell 2 or more times from 0.7% to 5%. A reduction in the rate of falls during the periods of activity was found. Mean attendance ranged from 75 to 83%. No significant relationship was found between attendance or age and the falls. Conclusions The reduced incidence of falls in the study and the reduction of the incidence rate during activity periods are used to propose a Geriatric Revitalization Program as an interesting and economical tool in preventing disability and maintaining quality of life in the elderly(AU)

Sludge valorization from wastewater treatment plant to its application on the ceramic industry.

The main aim of this study is to assess the effect of incorporating waste sludge on the properties and microstructure of clay used for bricks manufacturing. Wastewater treatment plants produce annually a great volume of sludge. Replacing clay in a ceramic body with different proportions of sludge can reduce the cost due to the utilization of waste and, at the same time, it can help to solve an environmental problem. Compositions were prepared with additions of 1%, 2.5%, 5%, 7.5%, 10% and 15% wt% waste sludge in body clay. In order to determine the technological properties, such as bulk density, linear shrinkage, water suction, water absorption and compressive strength, press-moulded bodies were fired at 950 °C for coherently bonding particles in order to enhance the strength and the other engineering properties of the compacted particles. Thermal heating destroys organic remainder and stabilizes inorganic materials and metals by incorporating oxides from the elemental constituent into a ceramic-like material. Results have shown that incorporating up to 5 wt% of sludge is beneficial for clay bricks. By contrast, the incorporation of sludge amounts over 5 wt% causes deterioration on the mechanical properties, therefore producing low-quality bricks.

Infección del sitio de salida de los catéteres venosos centrales y su asociación con bacteriemia relacionada con catéter / Infection of the exit site central venous catheters and its association with bacteremia related to catheter

Introducción: Los catéteres venosos centrales (CVC) plantean un alto riesgo de infección. La infección del sitio de salida (ISS-CVC) es la menos estudiada, y se desconoce su asociación con la bacteriemia asociada a catéter (BAC) y su impacto en la evolución del paciente. Objetivo: Evaluar la asociación entre ISS-CVC, BAC y mortalidad. Materiales y métodos: Estudio prospectivo, de observación. Pacientes internados en una Unidad de Terapia Intensiva médico/quirúrgica que requirieron la colocación de CVC desde el 01/06/2010 hasta el 01/04/2012. Se evaluaron datos epidemiológicos, BAC (según criterios de los CDC) y gérmenes. Se utilizaron media ± DE, mediana y rango intercuartílico, y porcentajes. Resultados: Durante este período, ingresaron 575 pacientes, el 98% requirió CVC. Datos de los pacientes: edad 41 ± 26 años, APACHE II 15 ± 7, 96% con ventilación mecánica, días de ventilación mecánica 41 (33-63), días de internación 43 (25-67). Todos los CVC con ISS fueron retirados y cultivados. Se observaron 51 ISS: 5,5/1000-días-catéter: 33% subclavia, 38% yugular, 29% femoral. Seis pacientes con ISS (12%) tuvieron BAC (0,65/1000-días-catéter): 3 subclavias, 2 yugulares, 1 femoral; 2 con halo y 8 con secreción purulenta. Tiempo de permanencia del CVC: 7,5 días (5-10). Clínica al momento de la ISS: shock 50%, fiebre 83%, SOFA 6 ± 3. El 83% de las infecciones fueron monomicrobianas: 83% por bacilos gramnegativos (2 Klebsiella, 2 Pseudomonas, 1 Serratia y 1 Acinetobacter), 17% por enterococos resistentes a vancomicina. La mortalidad fue del 50%. Conclusión: Aunque la ISS provocó una baja incidencia de BAC, la mortalidad fue alta. Al parecer, la ISS no es un factor predictivo de BAC.(AU)

Introduction: Central venous catheters (CVC) are widely used and pose a high risk of infection. There are few studies on insertion site infection (ISI-CVC), and both its association with catheter-associated bloodstream infection (CABSI) and the outcome of patients are unknown. Objective: To determine the association between ISI-CVC, the presence of CABSI and mortality. Materials and methods: Prospective observational study. All patients admitted to a medical/surgical Intensive Care Unit requiring CVC insertion from 06/01/2010 to 04/01/2012 were included. Epidemiological data, CABSI (according to CDC criteria) and microorganisms involved were evaluated. Mean ± SD, median and interquartile range, and percentages were used. Results: During the period study, 575 patients were admitted, 98% required CVC. Patient´s data: age 41 ± 26 years, APACHE II 15 ± 7, 96% on mechanical ventilation, days on mechanical ventilation: 41 (33-63), length of stay 43 (25-67) days. All CVCs with ISI were removed and cultured. Fifty one ISI were observed (5.5/1000-catheter-day). Six patients with ISI (12%) presented CABSI (0.65/1000-catheter-day): 3 in subclavian, 2 in jugular, 1 femoral; 2 with erythema and 8 with purulent secretion. CVC permanence: 7.5 day (5-10). Signs and/or symptoms at the moment of ISI: shock 50%, fever 83%, SOFA 6 ± 3. The 83% of infections were caused by one microorganism: 83% due to gram-negative bacilli (2 Klebsiella, 2 Pseudomonas, 1 Serratia, and 1 Acinetobacter), 17% due to vancomycin-resistant enterococci. The mortality rate was 50%. Conclusion: Although ISI-CVC presented a low incidence of CABSI, mortality rate was high. The ISI-CVC might have a little predictable value for CABSI.(AU)
