Predictive factors and prognostic effect of telomere shortening in pulmonary fibrosis.

BACKGROUND AND OBJECTIVE: The abnormal shortening of telomeres is a mechanism linking ageing to idiopathic pulmonary fibrosis (IPF) that could be useful in the clinical setting. The objective of this study was to identify the IPF patients with higher risk for telomere shortening and to investigate the outcome implications. METHODS: Consecutive Spanish patients were included at diagnosis and followed up for 3 years. DNA blood samples from a Mexican cohort were used to validate the results found in Spanish sporadic IPF. Prior to treatment, telomere length was measured through quantitative polymerase chain reaction (qPCR) and Southern blot. Outcome was assessed according to mortality or need for lung transplantation. A multivariate regression logistic model was used for statistical analysis. RESULTS: Family aggregation, age of <60 years and the presence of non-specific immunological or haematological abnormalities were associated with a higher probability of telomere shortening. Overall, 66.6% of patients younger than 60 years with telomere shortening died or required lung transplantation, independent of functional impairment at diagnosis. By contrast, in patients older than 60 years with telomere shortening, the negative impact of telomere shortening in outcome was not significant. CONCLUSION: Our data indicate that young sporadic IPF patients (<60 years) with some non-specific immunological or haematological abnormalities had higher risk of telomere shortening, and furthermore, they presented a poorer prognosis.

The therapeutic relationship from the perspective of patients and nurses in the first days of admission: A cross-sectional study in acute mental health units.

The therapeutic relationship (TR) is essential in mental health nursing care and plays a fundamental role in the understanding and treatment of the patient's health status. Despite being a bidirectional construct, limited evidence is available to shed light on this issue in mental health units and even less so in the first days of admission. This study aimed to examine the association and differences between nurses' and patients' perspectives on the establishment of the therapeutic relationship in acute mental health units during the first days of hospitalization. A cross-sectional study was carried out in 12 Spanish mental health units. Data were collected from patients and nurses using the Working Alliance Inventory-Short (WAI-S) questionnaire. A total of 234 cases were analysed, including 234 patients and 58 nurses. The results showed a positive association between nurses' and patients' perspectives on the therapeutic relationship, but also revealed significant differences on each WAI-S dimension. Nurses assigned higher scores compared to patients on the perception of the quality of the therapeutic relationship. The dimensions with the greatest weight from the patients' perspective regarding the quality of the therapeutic relationship were the perception of greater agreement on goals and tasks among nurses. This study demonstrates the importance of establishing shared goals and tasks with nurses from the first days of hospitalization to improve the quality of the therapeutic relationship as perceived by patients. These findings underline the need to consider the different perspectives of both parties to promote a high-quality therapeutic relationship.

[Smoking. Analysis of the scientific production in the SEPAR smoking area in 2009]. / Tabaquismo. Análisis de la producción científica en el Area de Tabaquismo de la SEPAR en el año 2009.

The SEPAR Smoking Area was started in the year 1995. Its main aims were to increase awareness of the problem of smoking among the members of our scientific society, to improve their scientific knowledge on this problem, to help in diagnostic and therapeutic interventions in smokers, and finally, to promote interventions for the prevention and treatment of smoking by the health and political administrations. Nowadays, it is the most dynamic areas of SEPAR and has more than 400 members. Throughout the year 2009, the health professionals of the SEPAR smoking area have carried out intense research work that has led to a reasonable scientific production that has covered different aspects of the discipline of smoking. The most impressive studies were those that tried to determine the impact that Law 28/2005 has had in the prevalence of smoking in Spain, the studies that assessed the scientific productivity of the area members and the numerous articles that published the results from different smoking units that are led by Spanish pneumologists.
