SEOM clinical guideline on hereditary colorectal cancer (2019).

In the last 2 decades, clinical genetics on hereditary colorectal syndromes has shifted from just a molecular characterization of the different syndromes to the estimation of the individual risk of cancer and appropriate risk reduction strategies. In the last years, new specific therapies for some subgroups of patients have emerged as very effective alternatives. At the same time, germline multigene panel testing by next-generation sequencing (NGS) technology has become the new gold standard for molecular genetics.

Immediate fire-induced changes in soil microbial community composition in an outdoor experimental controlled system.

Short-term fire-induced changes to the soil microbial community are usually closely associated to fire severity, which essentially consists in the fire-induced loss or decomposition of organic matter above ground and below ground. Many functional processes and soil properties, including plant recolonization and soil microorganism activity, depend on fire severity. Seven days after burning, we evaluated the impact of two fire severities (low and high) on basic soil properties and the microbial communities in an outdoor experimental controlled system composed of six forest soil monoliths. The magnitude of change in microbial community was far greater than the change in physical and chemical soil properties. Total N was the only selected soil property that significantly varied depending on fire severity. The severely burned soils experienced significant changes in overall microbial biomass composition and phylogenetic composition of bacterial communities in comparison with control plots. Immediately after the fire, in fact, phyla and genera such as Acidobacteria-Gp4 or Bacteroidetes-Ohtaekwangia were much more abundant in the control monoliths. On the other hand, Firmicutes or Proteobacteria (e.g. Firmicutes Paenibacillus, Proteobacteria Phenylobacterium) were relatively more abundant in the monoliths burned with high severity in comparison with the low severity burned ones. Overall, the effect of fire on soil microbial communities was greater in the high severity burned monoliths than in the low severity burned ones. We concluded that in Mediterranean forest ecosystems, fire significantly alters soil bacterial composition depending on its severity.

¿Cuál es el papel de la valoración geriátrica integral en Oncogeriatría? / What is the role of the comprehensive geriatric assessment in Geriatric Oncology?

El aumento creciente de la población mundial y el envejecimiento generalizado se han acompañado de un incremento en la prevalencia de cáncer en el anciano. El envejecimiento se asocia a determinados cambios fisiológicos, algunos de los cuales se potencian por la propia neoplasia. Junto a esto, el anciano oncológico suele tener más problemas que el resto de los individuos de edad avanzada, y es habitual que presente multitud de déficits. Estas características hacen necesario un manejo especial del mismo, utilizando, para ello, la principal herramienta empleada en Geriatría, la valoración geriátrica integral. Con este manuscrito se pretende analizar cuál es la trascendencia de la valoración geriátrica integral en dicho grupo poblacional, prestando especial atención a su capacidad para predecir la toxicidad a la quimioterapia y la supervivencia del anciano oncológico, y su capacidad para clasificar a estos pacientes en grupos que faciliten la toma de decisiones posterior

The growing increase in world population and generalised aging have been accompanied by an increase in the prevalence of cancer in the elderly. Aging is associated with certain physiological changes, some of which are enhanced by the neoplasm itself. Along with this, the elderly oncology patient usually has more problems than the rest of the elderly, and has a multitude of deficits. These characteristics require a special handling of the older patient with cancer, by using the main tool used in Geriatrics, the comprehensive geriatric assessment. This article analyses the importance of the comprehensive geriatric assessment in this population group, paying special attention to its ability to predict the toxicity of chemotherapy and the survival of the elderly oncology, as well as its ability to classify these patients into groups that help in the decision making process

Prospective analysis of psychological differences between adult and elderly cancer patients during postoperative adjuvant chemotherapy.

PURPOSE: Despite the burgeoning geriatric population with cancer and the importance of understanding how age may be related to mental adjustment and quality of life so far, differences in coping strategies and psychological harm between the elderly and adults are hardly being taken into account to modify the approach to this population. The aim of this prospective study is to describe the differences in psychological characteristics between older and adult cancer patients and examine dissimilarities in their psychological evolution during adjuvant chemotherapy. METHODS: Adults (18-69 years old) and older patients (≥ 70) with newly diagnosed non-metastatic resected cancer admitted to receive adjuvant chemotherapy were recruited. Patients completed the following questionnaires: mini-mental adjustment to cancer, brief symptom inventory, shared decision-making questionnaire-patient's version, multidimensional scale of perceived social support, EORTC quality-of-life instrument, life orientation test-revised, and satisfaction with life scale. RESULTS: 500 cancer patients (394 adults and 106 older) were evaluated. The impact of the diagnosis was less negative among older patients, with no differences in coping strategies, quality of life, or search for support. Regarding psychological changes from the beginning to the end of the adjuvant treatment, both age groups reported more somatic symptoms, increased psychological difficulty, reduced coping strategies, and a significant decrease in quality of life at the end of postoperative chemotherapy. CONCLUSION: Although there were clear psychological differences between adults and senior cancer patients, their evolution during adjuvant chemotherapy was similar, with deterioration in quality of life and coping. This negative psychological impact of adjuvant chemotherapy should be taken into account when considering interventions.
