Objective: To determine the Intensity of Collaboration between the intensive care professionals of a third level hospital., Method: Descriptive cross-sectional study with an analytical approach., Setting: 6 intensive care units of a third level hospital., Sample: nurses and doctors. Consecutive type non-probabilistic sampling., Data Collection: sociodemographic, economic, motivation and professional satisfaction variables, and the intensity of collaboration using the "Scale of Intensity of Interprofessional Collaboration in Health.", Results: A total of 102 health professionals (91 nurses and 11 doctors) were included. The mean overall Intensity of Collaboration (IoC) was moderate. Men showed higher scores in all factors (p<.05). The IoC global score was higher in the group of professionals with ≤10 years of experience (p=.043) and those who were highly satisfied with the profession (p=.037). Physicians presented higher scores in the global IdC (p=.037) and in the Collaboration mean (p=.020) independently in the multivariate models. A negative linear relationship (rho: -0,202, p=.042) was observed between age and the overall IoC score. Professionals aged ≤30years reported a higher perception of Shared Activities (p=.031). Negative linear relationships were observed between years of experience and total IoC score (rho: -0,202, p=.042) and patients' Perception score (rho: -0.241, p=0.015). The research activity also showed to be a variable related to a greater degree of Collaboration at a global level and in some of the factors (p<.05). The scale of IoC obtained a Cronbach's α of 0,9., Conclusions: The intensity of interprofessional collaboration in ICUs is moderate. Professionals with experience of ≤10 years, a higher level of satisfaction and participation in research activities show a greater intensity of collaboration. Doctors perceive collaboration more intensely than nurses. All factors contribute equally to the internal consistency of the questionnaire., (Copyright © 2023. Published by Elsevier España S.L.U.)

Background: The study of hepatitis B virus (HBV) genomic heterogeneity has become a major issue in investigations aimed at understanding the relationship between HBV mutants and the wide spectrum of clinical and pathological conditions associated with HBV infection. Although most chronically infected HBV patients are inactive carriers, several virological aspects of this state remain unclear., Methods: In order to determine the prevalence and clinical significance of mutations in the basal core promoter (BCP) and precore (pC) regions among inactive carriers, the nucleotide sequences from 41 inactive carriers were analyzed and compared with those from 29 individuals with chronic active hepatitis., Results: Genotypes A (24.3%), D (37.1%), F1b (12.9%), and F4 (18.6%) were the most prevalent. Mutations in the BCP/pC regions were observed in most of the inactive carriers (92.7%) and in most of the patients with chronic active hepatitis (93.1%). The prevalence of mutation 1764(A) was significantly higher in patients with chronic active hepatitis (65.5%) than in inactive carriers (36.6%) (p=0.038), whereas the prevalences of mutations at the other positions analyzed were not significantly different. Older patients (>50 years) showed BCP/pC patterns with a higher number of substitutions. Mutations were found to be biased by genotype: the 1896(A) mutation was highly prevalent in genotypes D and F4, while alternative substitutions in the pC region were more prevalent in genotypes A and F1b., Conclusions: Mutations in the BCP/pC regions are the hallmark of chronic anti-HBe-positive individuals; nevertheless, the even distribution of mutations in active and inactive carriers suggests that BCP/pC mutations may occur during HBV infection not strictly related to the HBV infection activity., (Copyright © 2011.
