[Functional decline and presence of symptoms in palliative care: Cause or consequence?] / Declive funcional y presencia de síntomas en cuidados paliativos: ¿causa o consecuencia?

INTRODUCTION: Several publications have related functional decline to the appearance of symptoms, especially psychiatric or psychological ones, such as anxiety and depression. Moreover, an initial depressive disorder or prior to functional decline usually worsens it. It was decided to investigate the relationship between the presence of functional decline, measured by a decrease in the Barthel index (BI), and the presence of symptoms. MATERIAL AND METHODS: A prospective analytical study conducted on patients referred to a Home Care Support Team (HCST). RESULTS: The study included 638 cases, of which 53.9% (N=344) were male, 56% (N=357) with cancer and 44% (N=281) geriatric. The mean age was 79.64 years+- 10.8. Significant differences (P<.001) were found in functional decline measured by mean decline in the BI between cancer (34.4) and non-cancer patients (12.12). Significant differences (P<.001) were also found in all recorded symptoms (pain, dyspnoea, anorexia, nausea, anxiety, depression, and insomnia), more frequently in cancer patients, except psychomotor agitation. A higher presence of symptoms was detected in patients with greater functional decline, with decreases in BI above 20 points. There were no differences in previous treatments, except in certain analgesics. Differences were found in the different treatments prescribed by HCST. CONCLUSIONS: The presence of functional decline and its level may be related to the appearance of symptoms, especially in cancer patients.

Heparinas de bajo peso molecular en la profilaxis de episodios tromboembólicos en pacientes con cáncer portadores de catéter venoso central / Role of low molecular weight heparins in prophylaxis of thromboembolic events on oncological patients with indwelling central venous catheter

Fundamento y objetivo: Este estudio pretende analizar la incidencia de trombosis de extremidades superiores y de embolia pulmonar en pacientes oncológicos portadores de catéter venoso central, así como valorar si las heparinas de bajo peso molecular (HBPM) podrían ser útiles en prevenir este tipo de episodios. Pacientes y método: Pacientes oncológicos portadores de catéter tipo porth a cath se trataron con bemiparina o no de forma no aleatorizada; se realizó seguimiento clínico y radiológico mediante flebografía el día 1 y ecografía Doppler los días 1, 45 y 90 tras la implantación. Se determinó la incidencia de trombosis en pacientes con o sin tratamiento con bemiparina sódica (3.500 U/día) y su relación con posibles factores de riesgo. Resultados: Se encontraron 19 episodios trombóticos en 148 pacientes elegibles: el 5,41% de trombosis venosa profunda de extremidad superior sintomática y el 2,03% asintomática; un caso de embolia pulmonar (0,68%); el 2,70% de disfunción del catéter, y el 2,03% de trombosis de extremidades inferiores. Hubo mayor porcentaje de episodios trombóticos en el grupo de tratamiento con HBPM (15,5%) que en el grupo sin profilaxis (9,4%); la diferencia no fue significativa (p=0,272). Los únicos factores de riesgo significativos fueron el tiempo de protrombina, la hipertensión arterial y el sobrepeso. Conclusiones: La colocación de catéteres venosos centrales es una técnica de gran utilidad, con bajo porcentaje de complicaciones trombóticas clínicamente manifiestas. La bemiparina sódica no presenta una relación favorable para disminuir el riesgo de trombosis en estos enfermos (AU)

Background and objective: Our study was designed to assess the incidence of thrombosis in the upper limbs and of pulmonary embolism in oncological patients with indwelling central venous catheters, and to evaluate, also, the potential role of LMWH to prevent these events. Patients and methods: Oncological patients undergoing placement of a central venous acccess (port-a-cath type) were treated with or without bemiparin in a non-randomized fashion. Assessment included clinical and radiological follow-up. A phlebography on the first day and ecodoppler on days 1th, 45th and 90th were performed. Patients received or not prophylactic bemiparin (3500UI/day) in a non-randomized way. The incidence of thrombosis in both groups was assessed as well as its relation with some risk factors. Results: One hundred and forty eight patients were eligible; 19 thrombotic events were found. The incidence of symptomatic upper extremity thrombosis was 5.41%, asymptomatic thrombosis in 2.03% ; there was one case of pulmonary embolism ( 0,68%); catheter failure occurred in 2.70%; incidence of lower extremities deep venous thrombosis was 2.03%. There was a higher percentage of events in the group of patients treated with bemiparin than in the not treated individuals (9.4%), although the difference did not reach statistical significance (p=0.27). The only risk factors reaching statistical significance were the prothrombin time, high blood pressure and overweight. Conclusions: Central venous catheters are very useful in oncology. The procedure was related with a low percentage of thrombotic complications. Sodic bemiparin does not reduce the thrombotic risk in these patients (AU)

Impacto de las unidades móviles de emergencia en la sobrevida del infarto agudo de miocardio / Impact of mobile emergency units on survival of patients having an acute myocardial infarction

OBJETIVO: Demostrar que los pacientes con Infarto Agudo de Miocardio (IAM) atendidos por una Unidad Móvil de Emergencia (UME) tienen menos complicaciones y menor gravedad que los pacientes que acuden al hospital en ambulancia convencional. METODOLOGÍA: Estudio descriptivo con contraste, entre 45 pacientes con IAM que habían sido atendidos por una UME y 50 pacientes con IAM que habían acudido al hospital en ambulancia convencional sin asistencia médica prehospitalaria. Se estudiaron los factores de riesgo cardiovascular en ambos grupos. Al objeto de determinar la influencia que la demora en el tratamiento tiene en la mayor o menor supervivencia y calidad de vida residual, los pacientes fueron clasificados según la distancia de su domicilio al centro hospitalario como urbanos <25 Km y rurales >25Km. RESULTADOS: En pacientes atendidos por una UME se producen menos complicaciones como fibrilación y taquicardia ventricular, bloqueos, paro cardiorrespiratorio y muerte, shock, insuficiencia cardíaca, edema agudo de pulmón, pericarditis, derrame pericárdico y ruptura cardíaca. CONCLUSIONES: El número de complicaciones y la gravedad de las mismas durante la fase evolutiva de un IAM es menor en pacientes que han sido atendidos inicialmente por una UME. La fracción de eyección residual es mejor en pacientes atendidos por una UME. Por todo ello, la calidad de vida residual es mejor en los pacientes que son atendidos en una UME
