RESUMO
AIM: Benzodiazepine prescription is a growing phenomenon among the elderly population. However, information related to the frequency of these drugs among the elderly population attending in emergency departments (ED) and its impact over prognosis is scarce. The aim of this study is to assess the prevalence of benzodiazepine prescription and to analyze its association with short-term prognosis in elderly patients attended in ED. METHODS: A retrospective analysis of the EDEN (Emergency Department Elderly in Need) cohort was conducted. This registry included all elderly patients attending in 52 Spanish EDs for any condition, between April 1st and 7th in 2019. Socio-demographic data, comorbidities, and medication were recorded by consulting the patient's electronic health records. The assessed outcomes consisted on new ED visit, hospitalization, and mortality at 30 days after the first ED visit, associated with the use of benzodiazepines at baseline in comparison with no prescription of benzodiazepines. Crude and adjusted logistic regression analyses including patient's comorbidities were performed. Two sensitivity analyses were performed considering concomitant prescription of other central nervous system depressants as well as direct discharge from the ED. RESULTS: 25 557 patients were evaluated (mean age 78 [IQR: 71-84]). 7865 (30.8%) patients were taken benzodiazepines at admission. After adjustment for comorbidities and other central nervous system drugs, benzodiazepine prescription was associated with ED revisit [OR: 1.10 (95%CI: 1.03-1.18)]. Similar results were found in the sensitivity analysis, eliminating patients with central nervous depressors [OR: 1.11 (1.03-1.25)] and patients discharged to home [OR: 1.13 (1.04-1.23)]. No association was found between the use of these drugs and new hospitalizations [OR: 0.90 (0.77-1.05)] or mortality 30 days after discharge [OR: 1.01 (0.88-1.18)]. The results held for all three outcomes in the sensitivity analyses. CONCLUSION: The use of benzodiazepines is a frequent phenomenon among the elderly population attended in the ED, being associated with an increased risk of new visits to the emergency room, but not with an increased risk of 30-day hospitalization or mortality.

AIM: To test the hypothesis that fluid adherence in patients on haemodialysis can be improved through nurses' solution-focused communication with patients on issues of adherence. BACKGROUND: Adherence to fluid-intake restrictions is low in patients on haemodialysis, creating serious health risks. Psychosocial interventions to increase adherence have typically focused on patients and ignored patient/staff interactions. DESIGN: This is a single-group, pre-post pilot study registered in ClinicalTrials.gov (identifier: NCT03432988). METHOD: A 1-month baseline of interdialytic weight gain was taken in April 2016 for a group of 36 adult patients in a hospital haemodialysis unit. Then, the nurses of the unit received a 4 hr training in solution-focused communication on issues of fluid adherence and applied it with the patients of the sample. Interdialytic weight gains were measured during another month. One month after the training, in October 2016, interdialytic weight gains were measured for another month. RESULTS: After introducing solution-focused communication on fluid adherence, patients' average interdialytic weight gains decreased significantly, below the level considered indicative of problematic adherence. These results were maintained at follow-up. CONCLUSIONS: Our results suggest that a novel approach to adherence, nurses' solution-focused communication with patients on haemodialysis, may improve patients' adherence to fluid restriction. More rigorous, controlled studies are required to confirm long-term benefits and to understand the causal mechanisms that may underlie the effectiveness of this intervention.

The breakdown of vascular integrity triggers a series of reactions, initially involving a vasoconstriction phenomenon that reduces blood loss and leads to platelet plug formation under changing flow conditions. Once the platelet plug has formed, the coagulation system is activated in order to allow the formation of fibrin, which anchors the platelet plug to the vessel breach. Finally, once the damage has resolved, the fibrin is eliminated through fibrinolysis. This article explains all these regulatory mechanisms.

Lipids are the most diverse class of metabolites in mammalian physiology and dysregulation of lipid metabolism is linked to various diseases. Alterations in acylglycerols, a major class of lipids in plasma and adipose tissue, are involved in the pathogenesis of obesity and type 2 diabetes. Therefore, determination of acylglycerols is important to depict and unravel cellular mechanisms related to pathological outcomes, and specific molecular species of acylglycerols might be promising biomarker candidates. The variety of acylglycerols can be characterized in different ways. Enzymatic assays enable the determination of total tri- or diacylglycerols showing a possible relation to diseases, but they do not allow clarification of molecular mechanism. While gas chromatography can provide an overview of the fatty acid composition of total or separated lipids, a very detailed description of the individual molecular acylglycerol species is possible via liquid chromatography, particularly when combined with mass spectrometry. This review describes the determination of acylglycerols considering recent developments, with a focus on mammalian serum/plasma and tissue.

Acquired thrombotic thrombocytopenic purpura is a life-threatening condition that rarely presents during pregnancy. Early diagnosis and treatment with plasma exchange is needed to achieve a good pregnancy outcome.
RESUMO
Single nucleotide polymorphisms (SNPs) in the genes encoding the fatty acid desaturase (FADS) and elongase (ELOVL) enzymes affect long-chain polyunsaturated fatty acid (LC-PUFA) production. We aimed to determine if these SNPs are associated with body mass index (BMI) or affect fatty acids (FAs) in pregnant women. Participants (n = 180) from the PREOBE cohort were grouped according to pre-pregnancy BMI: normal-weight (BMI = 18.5-24.9, n = 88) and overweight/obese (BMI≥25, n = 92). Plasma samples were analyzed at 24 weeks of gestation to measure FA levels in the phospholipid fraction. Selected SNPs were genotyped (7 in FADS1, 5 in FADS2, 3 in ELOVL2 and 2 in ELOVL5). Minor allele carriers of rs174545, rs174546, rs174548 and rs174553 (FADS1), and rs1535 and rs174583 (FADS2) were nominally associated with an increased risk of having a BMI≥25. Only for the normal-weight group, minor allele carriers of rs174537, rs174545, rs174546, and rs174553 (FADS1) were negatively associated with AA:DGLA index. Normal-weight women who were minor allele carriers of FADS SNPs had lower levels of AA, AA:DGLA and AA:LA indexes, and higher levels of DGLA, compared to major homozygotes. Among minor allele carriers of FADS2 and ELOVL2 SNPs, overweight/obese women showed higher DHA:EPA index than the normal-weight group; however, they did not present higher DHA concentrations than the normal-weight women. In conclusion, minor allele carriers of FADS SNPs have an increased risk of obesity. Maternal weight changes the effect of genotype on FA levels. Only in the normal-weight group, minor allele carriers of FADS SNPs displayed reduced enzymatic activity and FA levels. This suggests that women with a BMI≥25 are less affected by FADS genetic variants in this regard. In the presence of FADS2 and ELOVL2 SNPs, overweight/obese women showed higher n-3 LC-PUFA production indexes than women with normal weight, but this was not enough to obtain a higher n-3 LC-PUFA concentration.
