The Association of Hyponatremia with Race, Ethnicity, and Gender in Patients Admitted for Acute Decompensated Heart Failure Diagnoses
Background: Hyponatremia, defined by a serum sodium concentration less than 135 mEq/L, is seen in approximately 25% of patients admitted with congestive heart failure (CHF). Hyponatremia on admission has been shown to increase in-hospital mortality and to be an independent predictor of 6month mortality. Prior work has shown that CHF patients with hyponatremia on admission are more likely to be Caucasian. Given its prognostic significance, hyponatremia and its association with patient characteristics warrants further study.
Methods: We queried for unique admissions to Temple University Hospital between 2011 and 2015 with a DRG code of 291-293 to represent a heart failure admission. We identified admissions that had a first sodium lab value after admission available. Chi-square tests were performed to examine association between first Na\u3c135 mEq/L and ethnicity, gender, or ethnic/gender sub-group. Statistical significance was defined as p\u3c0.05.
Results: 884 admissions were identified by ethnicity as either African-American , Caucasian (Non-Hispanic) or Hispanic . There was no association between first Na\u3c135 mEq/L and ethnicity (Chi-squared=2.31; p=0.31). 976 admissions were identified as either male or female . There was no association between hyponatremia on admission and gender (Chi-squared=1.17; p=0.27). 768 patient admissions could be classified by both ethnicity and gender. The association between hyponatremia on admission and ethnic/gender sub-group did not achieve statistical significance (Chi-squared=9.49; p=0.09).
Conclusion(s): In conclusion, our study demonstrates no statistically significant association between hyponatremia and the patient characteristics ethnicity and gender in a small sample of heart failure admissions. There was a trend toward a lower proportion of African-American/Female admissions having hyponatremia
Identification of a truncated nucleoprotein in avian metapneumovirus-infected cells encoded by a second AUG, in-frame to the full-length gene
BACKGROUND: Avian metapneumoviruses (aMPV) cause an upper respiratory disease with low mortality, but high morbidity primarily in commercial turkeys. There are three types of aMPV (A, B, C) of which the C type is found only in the United States. Viruses related to aMPV include human, bovine, ovine, and caprine respiratory syncytial viruses and pneumonia virus of mice, as well as the recently identified human metapneumovirus (hMPV). The aMPV and hMPV have become the type viruses of a new genus within the Metapneumovirus. The aMPV nucleoprotein (N) amino acid sequences of serotypes A, B, and C were aligned for comparative analysis. Based on predicted antigenicity of consensus protein sequences, five aMPV-specific N peptides were synthesized for development of peptide-antigens and antisera. RESULTS: The presence of two aMPV nucleoprotein (N) gene encoded polypeptides was detected in aMPV/C/US/Co and aMPV/A/UK/3b infected Vero cells. Nucleoprotein 1 (N1) encoded from the first open reading frame (ORF) was predicted to be 394 amino acids in length for aMPV/C/US/Co and 391 amino acids in length for aMPV/A/UK/3b with approximate molecular weights of 43.3 kilodaltons and 42.7 kilodaltons, respectively. Nucleoprotein 2 (N2) was hypothesized to be encoded by a second downstream ORF in-frame with ORF1 and encoded a protein predicted to contain 328 amino acids for aMPV/C/US/Co or 259 amino acids for aMPV/A/UK/3b with approximate molecular weights of 36 kilodaltons and 28.3 kilodaltons, respectively. Peptide antibodies to the N-terminal and C-terminal portions of the aMPV N protein confirmed presence of these products in both aMPV/C/US/Co- and aMPV/A/UK/3b-infected Vero cells. N1 and N2 for aMPV/C/US/Co ORFs were molecularly cloned and expressed in Vero cells utilizing eukaryotic expression vectors to confirm identity of the aMPV encoded proteins. CONCLUSION: This is the first reported identification of potential, accessory in-frame N2 ORF gene products among members of the Paramyxoviridae. Genomic sequence analyses of related members of the Pneumovirinae other than aMPV, including human respiratory syncytial virus and bovine respiratory syncytial virus demonstrated the presence of this second potential ORF among these agents

Share Functions for Cooperative Games with Levels Structure of Cooperation
In a standard TU-game it is assumed that every subset of the player set can form a coalition and earn its worth. One of the first models where restrictions in cooperation are considered is the one of games with coalition structure. In such games the player set is partitioned into unions and players can only cooperate within their own union. Owen introduced a value for games with coalition structure under the assumption that also the unions can cooperate among them. Winter extended this value to games with levels structure of cooperation, which consists of a game and a finite sequence of partitions defined on the player set, each of them being coarser than the previous one. A share function for TU-games is a type of solution that assigns to every game a vector whose components add up to one, and thus they can be interpreted as players' shares in the worth to be allocated. Extending the approach to games with coalition structure developed by van den Brink and van der Laan (2005), we introduce a class of share functions for games with levels structure of cooperation by defining, for each player and each level, a standard TU-game. The share given to each player is then defined as the product of her shares in the games at every level. We show several desirable properties and provide axiomatic characterizations of this class of LS-share functions
Segurança do paciente, sua percepção pela equipe de enfermagem em um hospital materno-infantil
Introduction: patient safety is a challenge for nurses, so it is necessary to develop, monitor and evaluate quality and safety indicators that are measurable, objective, relevant and based in real evidence. Objective: to describe the perceptions concerning the patient safety culture among the nursing staff of the Critical care service in a mother and child hospital in the Ciudad Autónoma de Buenos Aires. Method: an observational, descriptive, cross-sectional, descriptive study was conducted between August and October 2021. The accessible population consisted of 57 nursing professionals. The Hospital Survey on Patient Safety Culture was used as an instrument. Results: after analyzing the perceptions according to dimensions, it was found that the dimension with the highest values was 7 at feedback and communication about errors. The rest of the dimensions obtained scores in neutral range, with values less than or equal to 4 points. The Kruskal-Wallis test was applied, and no statistically significant differences were found between the groups in any of the four variables analyzed.Conclusions: in the analysis concerning patient safety culture found non-negative perceptions where feedback and communication about errors was the only dimension with a positive score among the nurses surveyed. Finally, it should be noted that it was not possible to establish that the organizational culture of patient safety was conditioned by sociodemographic or training indicators.Introducción: la seguridad del paciente constituye un desafío para el personal de enfermería, por lo que se hace necesario el desarrollo, seguimiento y evaluación de indicadores de calidad y seguridad medibles, objetivos, relevantes y basados en la evidencia.
