Cómo validar un instrumento de medida de la salud

Abstract: It is increasingly necessary to have a measuring instrument available in the health field that can be used in clinical practice and research. In order to guarantee the quality of their measurements it is essential that the instruments should be subjected to a process of validation. This process consists in adapting the instrument culturally to the setting where its psychometric characteristics are to be administered and checked, such as: reliability, validity, sensitivity and feasibility. There are measuring instruments from the health field available in other languages but that have not been validated into Spanish. Besides, the methodology for validating an instrument is little understood by the health professionals, which explains the indiscriminate use of instruments that have only been adapted or validated in a way that is not very consistent. The aim of this review is to bring up to date the process of validating an instrument for measuring health, and what it involves, in a practical way. The accessibility of evaluation instruments that have been culturally adapted and validated in different languages will facilitate the comparison of results obtained with the same instrument and the development international studies in different cultures.

Validación de la Escala INFLESZ para evaluar la legibilidad de los textos dirigidos a pacientes

Abstract: Background: The readability of written texts aimed at patients is an indicator of quality. Szigriszt made an adaptation of the RES Flesch Score, calling it “Escala de Nivel de Perspicuidad” (Clarity Level Scale), to measure the difficulty in reading a text. But Szigriszt used a text sample that was neither representative nor random, which is why the conclusions are not sufficiently consistent. The aim of this article is to complete the process begun by Szigriszt, review the Szigriszt Scale, comparing it with Flesch’s scale, and propose a scale according to Spanish reading habits. Methods. Descriptive study. Two hundred and ten documents of 3 types were selected at random: Stationary magazines, school textbooks and scientific magazines. Three fragments of at least 500 words were chosen at random from each one, from the beginning, middle and end. The Flesch-Szigriszt Index (Indice de Legibilidad de Flesch-Szigriszt [IFSZ]), available on the INFLESZ program, was calculated. The scores were classified according to the Flesch and Szigriszt scales. Results. The readability of the stationary magazines is 60, of scientific magazines 37.9, and school textbooks 67.39. Conclusions. Only the scientific magazines are situated between 0 and 50. There are no publications with scores lower than 15. Szigrsizt locates “Normal” from 50; Flesch from 60. An intermediate position is adopted and a new scale is proposed: the INFLESZ Scale, which establishes 5 sections: “Very difficult” ( 80). Neither the Clarity Level Scale of Szigriszt nor the RES Flesch Score are adapted to Spanish reading habits. In the case of texts on health, there is a greater probability of their being read and understood if they exceed 55.

Thrombosis and cancer

Abstract: Venous thromboembolic disease is a serious complication in patients with cancer. Although its incidence is not well known, the association between thromboembolic disease and cancer is frequent and is in itself an emergency. Facing clinical manifestations compatible with thromboembolic disease, it is imperative to elaborate a complete clinical history in order to know which is the tumour the patient is suffering from and if there are associated risk factors (if he is the bearer of a central venous catheter, if he is receiving treatment with chemotherapy, if his cancer has undergone a surgical intervention). Subsequently, if we hold a high suspicion of venous thromboembolic disease, treatment should be started without waiting for an immediate diagnostic confirmation. Treatment in the oncology patient is similar to that in the non-oncology patient, but greater attention should be paid to the complications deriving from the treatment, such as haemorrhaging, since this can worsen the prognosis of the patient. Due to that, efforts should be directed towards a good antithrombotic prophylaxis.

Situación del cáncer en España: incidencia

Abstract: It is estimated that at present in Spain around 162,000 cases of cancer are diagnosed each year (without including non-melanoma skin cancer), of which 25,600 correspond to colorectal carcinomas, which is the most frequent of all tumours in absolute terms. The next tumour in terms of frequency is lung cancer with 18,800 new cases, followed by breast cancer in women with 15,979 cases. When the incidence of cancer is compared with that in neighbouring countries, Spain shows adjusted rates in men higher than those of the average for the EU, occupying the 5th place. However, in women, Spain shows the lowest rates together with Greece. Spain occupies the first place for cancer of the bladder in men, with rates that are considerably higher than those of the rest of the countries. It is important to verify the increase underway in the incidence of cancer in Spain and the contrast that this represents facing the evolution of mortality. For many important tumoral localisations (lung, stomach, bladder), the population registers do not cover the provinces where there is a greater mortality.

Biofilms bacterianos e infección

Abstract: In developed countries we tend to think of heart disease and the numerous forms of cancer as the main causes of mortality, but on a global scale infectious diseases come close, or may even be ahead: 14.9 million deaths in 2002 compared to cardiovascular diseases (16.9 million deaths) and cancer (7.1 million deaths) (WHO report 2004). The infectious agents responsible for human mortality have evolved as medical techniques and hygienic measures have changed. Modern-day acute infectious diseases caused by specialized bacterial pathogens such as diphtheria, tetanus, cholera, plague, which represented the main causes of death at the beginning of XX century, have been effectively controlled with antibiotics and vaccines. In their place, more than half of the infectious diseases that affect mildly immunocompromised patients involve bacterial species that are commensal with the human body; these can produce chronic infections, are resistant to antimicrobial agents and there is no effective vaccine against them. Examples of these infections are the otitis media, native valve endocarditis, chronic urinary infections, bacterial prostatitis, osteomyelitis and all the infections related to medical devices. Direct analysis of the surface of medical devices or of tissues that have been foci of chronic infections shows the presence of large numbers of bacteria surrounded by an exopolysaccharide matrix, which has been named the "biofilm". Inside the biofilm, bacteria grow protected from the action of the antibodies, phagocytic cells and antimicrobial treatments. In this article, we describe the role of bacterial biofilms in human persistent infections.
