SEOM-GEMCAD-TTD clinical guidelines for the systemic treatment of metastatic colorectal cancer (2022)

Colorectal cancer; Metastatic disease; Systemic treatmentCàncer colorectal; Malaltia metastàtica; Tractament sistèmicCáncer colorrectal; Enfermedad metastásica; Tratamiento sistémicoColorectal cancer (CRC) is the second leading cause of cancer deaths in Spain. Metastatic disease is present in 15–30% of patients at diagnosis and up to 20–50% of those with initially localized disease eventually develop metastases. Recent scientific knowledge acknowledges that this is a clinically and biologically heterogeneous disease. As treatment options increase, prognosis for individuals with metastatic disease has steadily improved over recent decades. Disease management should be discussed among experienced, multidisciplinary teams to select the most appropriate systemic treatment (chemotherapy and targeted agents) and to integrate surgical or ablative procedures, when indicated. Clinical presentation, tumor sidedness, molecular profile, disease extension, comorbidities, and patient preferences are key factors when designing a customized treatment plan. These guidelines seek to provide succinct recommendations for managing metastatic CRC

Relationship of Binge Drinking with Impairments Affecting Memory and Executive Function among University Students: A Cross-Sectional Study in Northern Spain

Binge drinking (BD) is a common practice among college students. Alcohol consumption may affect brain structures that continue to develop in early adulthood. The aim of this study was to analyze the relationship of BD with impairments affecting memory and executive function among university students. A cross-sectional study was conducted among students (aged 18?30 years) enrolled for the academic year 2018?2019 at the Faculty of Nursing of the University of Cantabria (Spain). Data collection included sociodemographic and academic information, together with alcohol and drug use information, collected by means of a semi-structured questionnaire. A battery of validated tests was used to gather neuropsychological variables. A total of 142 participants were included, of which 88.03% were women. Up to 38.03% were classified as BD. No differences were found in memory tests. Regarding executive function, better performance in the Stroop Color andWord Test was observed in non-BD but the results were not statistically significant. In conclusion, no relationship was found between memory and executive function and BD, although better performance in executive function, specifically inhibitory control, was observed in non-BD

Excessive alcohol consumption and binge drinking in college students

Background: Binge drinking (BD) refers to a pattern of alcohol consumption characterized by the consumption of large amounts of alcohol in a short period of time followed by periods of abstinence. This drinking pattern is prevalent worldwide, mainly among young people. Excessive alcohol consumption is the spectrum of consumption patterns that may have or have had health consequences, and includes the concepts of risky alcohol use, harmful alcohol use and alcohol dependence according to Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV), the latter two are currently grouped into alcohol use disorder (AUD) according to the fifth edition of the DSM (DSM-5). Due to the high prevalence of BD among young people, especially university students, as well as the important consequences of its practice, a study was conducted to evaluate excessive alcohol consumption and its relationship with the practice of BD in university students. Methods: A cross-sectional study was conducted among students (aged 18-30 years) enrolled in the academic year 2018-2019 at the Faculty of Nursing at a university in northern Spain. Data collection included sociodemographic information, and alcohol use information, collected using a semi-structured questionnaire. To measure the excessive alcohol consumption, this study used the Alcohol Use Disorders Identification Test (AUDIT). Results: A total of 142 participants were included, of which 88.03% were women. Up to 38.03% were classified as BD. Up to 14.77% of non-BD participants and 66.67% of BD participants were classified as risky drinkers (AUDIT Total geq 8 in men or geq 6 in women) (p < 0.001). Up to 3.41% of the non-BD and 24.07% of the BD were drinkers with harmful alcohol use and probable alcohol dependence (AUDIT Total geq 13) (p < 0.001). A total of 5.68% of non-BD and 42.59% of BD were AUD drinkers (AUDIT Total geq 9 in males or geq 8 in females) (p < 0.001). In addition, statistically significant differences were found between the BD and non-BD groups in the responses to each of the AUDIT items, as well as in the total score and also in the scores of the three domains of the questionnaire. Conclusions: Excessive alcohol consumption is frequent among university students, especially among those who practice BD

Fibrosis in chronic kidney disease: Pathogenesis and consequences

Fibrosis is a process characterized by an excessive accumulation of the extracellular matrix as a response to different types of tissue injuries, which leads to organ dysfunction. The process can be initiated by multiple and different stimuli and pathogenic factors which trigger the cascade of reparation converging in molecular signals responsible of initiating and driving fibrosis. Though fibrosis can play a defensive role, in several circumstances at a certain stage, it can progressively become an uncontrolled irreversible and self-maintained process, named pathological fibrosis. Several systems, molecules and responses involved in the pathogenesis of the pathological fibrosis of chronic kidney disease (CKD) will be discussed in this review, putting special attention on inflammation, renin-angiotensin system (RAS), parathyroid hormone (PTH), fibroblast growth factor 23 (FGF23), Klotho, microRNAs (miRs), and the vitamin D hormonal system. All of them are key factors of the core and regulatory pathways which drive fibrosis, having a great negative kidney and cardiac impact in CKD

Relationship between Depressive Symptoms, Personality, and Binge Drinking among University Students in Spain

Binge drinking (BD) is a common practice among college students. Alcohol consumption has been related to depressive symptoms and certain personality factors, although less is known about the relationship of these variables with BD. The aim of this study was to analyze the relationship of BD with depressive symptoms and personality in university students. We performed a cross-sectional study among students (aged 18?30 years) enrolled in the academic year 2018-2019 at the Faculty of Nursing of the University of Cantabria (Spain). Sociodemographic, academic, and alcohol and other drug use information was collected by means of a semi-structured questionnaire. The Beck Depression Inventory-II was used to measure depressive symptomatology and the Neo Five-Factor Inventory was used for personality. A total of 142 participants were included, 88.03% of which were women. Up to 38.03% were classified as BD. Concerning depressive symptoms, 7.41% of BD were at the moderate-severe level compared to 3.41% of non-BD (p = 0.7096). Regarding personality, the median score for extraversion of BD was 35 (Q1 = 29, Q3 = 40), 32 (Q1 = 28, Q3 = 36) in non-BD (p = 0.0062), conscientiousness scored 34 (Q1 = 30.5, Q3 = 38) points in non-BD, 31.50 (Q1 = 27, Q3 = 37) in BD (p = 0.0224). In conclusion, BD students have higher levels of extraversion and lower levels of responsibility than non-BD students. No significant differences were found between the level of depressive symptomatology between BD and non-BD students

MicroRNA-145 and microRNA-486 are potential serum biomarkers for vascular calcification

INTRODUCTION: MicroRNAs (miRs) regulate vascular calcification (VC), and their quantification may contribute to suspicion of the presence of VC. METHODS: The study was performed in four phases. Phase 1: miRs sequencing of rat calcified and non-calcified aortas. Phase 2: miRs with the highest rate of change, plus miR-145 [the most abundant miR in vascular smooth muscle cells (VSMCs)], were validated in aortas and serum from rats with and without VC. Phase 3: the selected miRs were analyzed in epigastric arteries from kidney donors and recipients, and serum samples from general population. Phase 4: VSMCs were exposed to different phosphorus concentrations, and miR-145 and miR-486 were overexpressed to investigate their role in VC. RESULTS: miR-145, miR-122-5p, miR-486 and miR-598-3p decreased in the rat calcified aortas, but only miR-145 and miR-486 were detected in serum. In human epigastric arteries, miR-145 and miR-486 were lower in kidney transplant recipients compared with donors. Both miRs inversely correlated with arterial calcium content and with VC (Kauppila index). In the general population, the severe VC was associated with the lowest serum levels of both miRs. The receiver operating characteristic curve showed that serum miR-145 was a good biomarker of VC. In VSMCs exposed to high phosphorus, calcium content, osteogenic markers (Runx2 and Osterix) increased, and the contractile marker (α-actin), miR-145 and miR-486 decreased. Overexpression of miR-145, and to a lesser extent miR-486, prevented the increase in calcium content induced by high phosphorus, the osteogenic differentiation and the loss of the contractile phenotype. CONCLUSION: miR-145 and miR-486 regulate the osteogenic differentiation of VSMCs, and their quantification in serum could serve as a marker of VC

Mineral and Bone Metabolism Markers and Mortality in Diabetic Patients on Haemodialysis

© The Author(s) 2023. Published by Oxford University Press on behalf of the ERA.BACKGROUND: Diabetic patients on haemodialysis have a higher risk of mortality than non-diabetic patients. The aim of this COSMOS analysis was to assess whether bone and mineral laboratory values (calcium, phosphorus, and PTH) contribute to such risk. METHODS: COSMOS is a multicentre, open-cohort, 3-year prospective study, which includes 6797 patients from 227 randomly selected dialysis centres from 20 European countries. The association between mortality and calcium, phosphate or PTH was assessed using Cox proportional hazard regression models using both penalized splines smoothing and categorization according to KDIGO guidelines. The effect modification of the association between the relative risk of mortality and serum calcium, phosphate or PTH by diabetes was assessed. RESULTS: There was a statistically significant effect modification of the association between the relative risk of mortality and serum PTH by diabetes (p = 0.011). The slope of the curve of the association between increasing values of PTH and relative risk of mortality was steeper for diabetic compared with non-diabetic patients, mainly for high levels of PTH. In addition, high serum PTH (> 9 times the normal values) was significantly associated with a higher relative risk of mortality in diabetic patients but not in non-diabetic patients (1.53[95%CI:1.07-2.19] and 1.17[95%CI:0.91-1.52]). No significant effect modification of the association between the relative risk of mortality and serum calcium or phosphate by diabetes was found (p = 0.2 and p = 0.059, respectively). CONCLUSION: The results show a different association of PTH with the relative risk of mortality in diabetic and non-diabetic patients. These findings could have relevant implications for the diagnosis and treatment of CKD-MBD.publishersversionpublishe
