Factors related to medication errors in the preparation and administration of intravenous medication in the hospital environment

Background Medication errors have long been associated with low-quality medical care services and significant additional medical costs. Objective The aim of this study was to culturally adapt and validate the questionnaire on knowledge, attitudes and behaviors in the administration of intravenous medication, as well as to explore these factors in a hospital setting. Methods The study was divided into two phases: 1) validation and cross-cultural adaptation, and 2) cross-sectional study. A total of 276 hospital-based nursing professionals participated in the study. Results A Cronbach’s alpha value of 0.849 was found, indicating good internal consistency. In the multivariate analysis, statistically significant differences were found between knowledge and attitudes, demonstrating that having greater suitable knowledge correlates with having a more positive attitude. It was also discovered that having a positive attitude as well as the necessary knowledge increases the possibility of engaging in adequate behaviors. Conclusions The knowledge, attitudes and behavior questionnaire has a satisfactory internal consistency in order to be applied to the Spanish context. Implications for nursing management: Knowledge acquisition and positive attitude are both factors which promote adequate behavior, which in turn seems to have an impact on medication errors prevention. Health institutions must encourage continuous education for their employees.
Trajectories of change after a health-education program in Japan: decay of impact in anxiety, depression, and patient-physician communication

Background Health education can benefit people with chronic diseases. However, in previous research those benefits were small, and reinforcement to maintain them was not effective. A possible explanation is that the benefits appeared to be small and reinforcement appeared to be ineffective because those analyses mixed data from two latent groups: one group of people who needed reinforcement and one group of people who did not. The hypothesis is that mixing the data from those two different groups caused the true effects to be “diluted. ” Methods To test that hypothesis we used data from the Chronic Disease Self-Management Program in Japan, focusing on anxiety, depression, and patient-physician communication. To identify latent trajectories of change after the program, we used growth-mixture modeling. Then, to find out which baseline factors were associated with trajectory-group membership, we used logistic regression. Results Growth-mixture modeling revealed two trajectories – two groups that were defined by distinct patterns of change after the program. One of those patterns was improvement followed by backsliding: decay of impact. On anxiety and depression the decay of impact was large enough to be clinically important, and its prevalence was as high as 50%. Next, logistic regression analysis revealed that being in the decay-of-impact group could be predicted from multimorbidity, low self-efficacy, and high scores on anxiety or depression at baseline. In addition, one unexpected finding was an association between multimorbidity and better patient-physician communication. Conclusions These results support the hypothesis that previous findings (i.e. apparently small effect sizes and apparently ineffective reinforcement) actually reflect “dilution” of large effects, which was caused by mixing of data from distinct groups. Specifically, there was one group with decay of impact and one without. Thus, evaluations of health education should include analyses of trajectory-defined groups. These results show how the group of people who are most likely to need reinforcement can be identified even before the educational program begins. Extra attention and reinforcement can then be tailored. They can be focused specifically to benefit the people with the greatest need.
Pathological characteristics of Ccdc85c knockout rats: a rat model of genetic hydrocephalus

Spontaneous hhy mice show hydrocephalus and subcortical heterotopia, and a mutation in the Ccdc85c gene has been identified. To contribute to the comparison of the role of Ccdc85c in different species, we established a Ccdc85c KO rat and investigated its pathological phenotypes. Ccdc85c KO rats were produced by genomic engineering using transcription activator-like effector nuclease (TALEN). The KO rats had an approximately 350-bp deletion in Ccdc85c and lacked CCDC85C protein expression. The KO rats showed non-obstructive hydrocephalus, subcortical heterotopia, and intracranial hemorrhage. The KO rats had many pathological characteristics similar to those in hhy mice. These results indicate that CCDC85C plays an important role in cerebral development in rats, and the function of CCDC85C in the cerebrum are similar in rats and mice.
Assessment of the systematic errors caused by diffusion gradient inhomogeneity in DTI‐computer simulations

Diffusion tensor imaging (DTI) is a powerful MRI modality that allows the investigation of the microstructure of tissues both in vivo and noninvasively. Its reliability is strictly dependent on the performance of diffusion‐sensitizing gradients, of which spatial nonuniformity is a known issue in the case of virtually all clinical MRI scanners.
The gut microbiota influences skeletal muscle mass and function in mice

Transplanting the gut microbiota of pathogen-free mice into germ-free mice improves skeletal muscle mass and strength. Of microbial metabolites and muscle Skeletal muscle is important not only for locomotion but also for regulating metabolic function. Lahiri et al. studied the interactions between the gut microbiota and skeletal muscle in mice. They identified genes and signaling pathways involved in the regulation of skeletal muscle mass and function that responded to cues from the gut microbiota. Additional biochemical and functional analysis also revealed the influence of the gut microbiota on the function of neuromuscular junctions. These findings open the door to a better understanding of the role of the gut microbiota in the mechanisms underlying loss of muscle mass. The functional interactions between the gut microbiota and the host are important for host physiology, homeostasis, and sustained health. We compared the skeletal muscle of germ-free mice that lacked a gut microbiota to the skeletal muscle of pathogen-free mice that had a gut microbiota. Compared to pathogen-free mouse skeletal muscle, germ-free mouse skeletal muscle showed atrophy, decreased expression of insulin-like growth factor 1, and reduced transcription of genes associated with skeletal muscle growth and mitochondrial function. Nuclear magnetic resonance spectrometry analysis of skeletal muscle, liver, and serum from germ-free mice revealed multiple changes in the amounts of amino acids, including glycine and alanine, compared to pathogen-free mice. Germ-free mice also showed reduced serum choline, the precursor of acetylcholine, the key neurotransmitter that signals between muscle and nerve at neuromuscular junctions. Reduced expression of genes encoding Rapsyn and Lrp4, two proteins important for neuromuscular junction assembly and function, was also observed in skeletal muscle from germ-free mice compared to pathogen-free mice. Transplanting the gut microbiota from pathogen-free mice into germ-free mice resulted in an increase in skeletal muscle mass, a reduction in muscle atrophy markers, improved oxidative metabolic capacity of the muscle, and elevated expression of the neuromuscular junction assembly genes Rapsyn and Lrp4. Treating germ-free mice with short-chain fatty acids (microbial metabolites) partly reversed skeletal muscle impairments. Our results suggest a role for the gut microbiota in regulating skeletal muscle mass and function in mice.
Which modifiable prenatal factors mediate the relation between socioeconomic position and a child's weight and length at birth?

Although several studies have shown a positive association between socioeconomic position and size at birth, not enough is known about the modifiable factors that may be involved. We aimed to investigate whether maternal prepregnancy body mass index (BMI), smoking, diet, and depression during pregnancy mediate the positive association between maternal education and birth size. Weight and length z-scores specific for gestational age and sex were calculated for 1,500 children from the EDEN mother-child cohort. A mediation analysis of the associations between maternal education and birth size was conducted with a counterfactual method, adjusted for recruitment center, parity, maternal height, and age. In the comparison of children of mothers with low vs. intermediate education levels, maternal smoking during pregnancy explained 52% of the total effect of education on birth weight. Similar findings were observed with birth length z-score (37%). The comparison of children of mothers with high vs. intermediate education levels yielded a non-significant total effect, which masked opposite mediating effects by maternal BMI and smoking during pregnancy on both birth weight and length. Prepregnancy BMI and maternal smoking during pregnancy mediate the positive association between maternal education and birth weight and length z-scores. These mediators, however, act in opposite directions, thereby masking the extent to which healthy prenatal growth is socially differentiated.
Effect of seed rate, row spacing and fertility levels on growth and nutrient uptake of soybean (Glycine max. L.) under temperate conditions.

A field experiment was conducted at Shalimar Campus during kharif seasons of 2004 and 2005 on a silty clay loam soil, medium in available N and K, low in available P to study the production performance of soybean as influenced by seed rate, row spacing and fertility levels under temperate conditions. The experiment comprising 27 treatment combinations viz., 3 levels each of seed rate (40, 60 and 80 kg ha -1 ), row spacing (30, 45 and 60 cm) and fertility (40:60:40, 60:90:60 and 80:120:80 of N: P2O5 :K2O kg ha -1 ) was laid out in split plot design replicated thrice. Application of N80 P120 K80 kg ha -1 significantly improved the growth parameters viz., plant height, LAI, number of nodules plant -1 , fresh nodule weight and dry matter accumulation. Uptake of nutrients both N and P were increased with increase in fertility levels. Significantly more protein and oil content were also recorded at highest fertility level of N P2O5 K2O i.e. N80 P120 K80 kg ha -1
Aberrant X chromosome skewing and acquired clonal hematopoiesis in adult-onset common variable immunodeficiency

Advances in genomic medicine have elucidated an increasing number of genetic etiologies for patients with common variable immunodeficiency (CVID). However, there is heterogeneity in clinical and immunophenotypic presentations and a limited understanding of the underlying pathophysiology of many cases. The primary defects in CVID may extend beyond the adaptive immune system, and the combined defect in both the myeloid and lymphoid compartments suggests the mechanism may involve bone marrow output and earlier progenitors. Using the methylation profile of the human androgen receptor (AR) gene as a surrogate epigenetic marker for bone marrow clonality, we examined the hematopoietic compartments of patients with CVID. Our data show that clonal hematopoiesis is common among patients with adult-onset CVID who do not have associated noninfectious complications. Nonblood tissues did not show a skewed AR methylation status, supporting a model of an acquired clonal hematopoietic event. Attenuation of memory B cell differentiation into long-lived plasma cells (CD20–CD27+CD38+CD138+) was associated with marked changes in the postdifferentiation methylation profile, demonstrating the functional consequence of clonal hematopoiesis on humoral immunity in these patients. This study sheds light on a potential etiology of a subset of patients with CVID, and the findings suggest that it is a stage of an acquired lymphocyte maturation disorder.
Digital Leadership Skills and Associations with Psychological Well-Being

Due to increasing digitalisation, today’s working world is changing rapidly and provides managers with new challenges. Digital leadership is an important factor in managing these challenges and has become a key concept in the discussion about what kinds of skills managers need for digital transformation. The main research question our study explored was if digital leadership is associated with psychological well-being in upper-level managers. Based on a qualitative pilot study and relevant literature, we developed a new scale for digital leadership in managers. We conducted an online survey with a sample of 368 upper-level managers from a large German ICT-company. Using a stepwise logistic regression analysis, potential effects of digital leadership on psychological well-being (WHO-5) were analysed. Logistic regression analyses showed that better skills in digital leadership were significantly associated with higher well-being. Results also showed that gender, age and managerial experience had no effect in our model. Our study provides a valuable insight into the association between digital leadership and well-being in managers. However, further research is necessary to validate the newly developed scale for digital leadership and to confirm a causal effect in the relationship between digital leadership and well-being.
Effectiveness of school–home intervention for adolescent obesity prevention: parallel school randomised study

Abstract Many school-based interventions for obesity prevention have been proposed with positive changes in behaviour, but with unsatisfactory results on weight change. The objective was to verify the effectiveness of a combined school- and home-based obesity prevention programme on excessive weight gain in adolescents. Teachers delivered the school-based primary prevention programme to fifth- and sixth-graders (nine schools, forty-eight control classes, forty-nine intervention classes), which included encouraging healthy eating habits and physical activity. A subgroup of overweight or obese adolescents also received a home-based secondary prevention programme delivered by community health professionals. Schools were randomised to intervention or control group. Intent-to-treat analysis used mixed models for repeated continuous measures and considered the cluster effect. The main outcomes were changes in BMI and percentage body fat (%body fat) after one school-year of intervention and follow-up. Against our hypothesis, BMI increased more in the intervention group than in the control group (Δ = 0·3 kg/m2; P = 0·05) with a greater decrease in %body fat among boys (Δ = –0·6 %; P = 0·03) in the control group. The intervention group increased physical activity by 12·5 min per week compared with the control group. Female adolescents in the intervention group ate healthier items more frequently than in the control group. The subgroup that received both the school and home interventions had an increase in %body fat than in the control group (Δ = 0·89 %; P = 0·01). In the present study, a behavioural change led to a small increase in physical activity and healthy eating habits but also to an overall increase in food intake.
Analytical and clinical validation of a novel amplicon-based NGS assay for the evaluation of circulating tumor DNA in metastatic colorectal cancer patients

Abstract Background Evaluating the tumor RAS/BRAF status is important for treatment selection and prognosis assessment in metastatic colorectal cancer (mCRC) patients. Correction of artifacts from library preparation and sequencing is essential for accurately analyzing circulating tumor DNA (ctDNA) mutations. Here, we assessed the analytical and clinical performance of a novel amplicon-based next-generation sequencing (NGS) assay, Firefly™, which employs a concatemer-based error correction strategy. Methods Firefly assay targeting KRAS/NRAS/BRAF/PIK3CA was evaluated using cell-free DNA (cfDNA) reference standards and cfDNA samples from 184 mCRC patients. Plasma results were compared to the mutation status determined by ARMS-based PCR from matched tissue. Samples with a mutation abundance below the limit of detection (LOD) were retested again by droplet digital polymerase chain reaction (ddPCR) or NGS. Results The Firefly assay demonstrated superior sensitivity and specificity with a 98.89% detection rate at an allele frequency (AF) of 0.2% for 20 ng cfDNA. Generally, 40.76% and 48.37% of the patients were reported to be positive by NGS of plasma cfDNA and ARMS of FFPE tissue, respectively. The concordance rate between the two platforms was 80.11%. In the pre-treatment cohort, the concordance rate between plasma and tissue was 93.33%, based on the 17 common exons that Firefly™ and ARMS genotyped, and the positive percent agreement (PPA) and negative percent agreement (NPA) for KRAS/NRAS/BRAF/PIK3CA were 100% and 99.60%, respectively. Conclusions Total plasma cfDNA detected by Firefly offers a viable complement for mutation profiling in CRC patients, given the high agreement with matched tumor samples. Together, these data demonstrate that Firefly could be routinely applied for clinical applications in mCRC patients.
Exposure of Pseudomonas aeruginosa to bactericidal hypochlorous acid during neutrophil phagocytosis is compromised in cystic fibrosis

Myeloperoxidase is a major neutrophil antimicrobial protein, but its role in immunity is often overlooked because individuals deficient in this enzyme are usually in good health. Within neutrophil phagosomes, myeloperoxidase uses superoxide generated by the NADPH oxidase to oxidize chloride to the potent bactericidal oxidant hypochlorous acid (HOCl). In this study, using phagocytosis assays and LC-MS analyses, we monitored GSH oxidation in Pseudomonas aeruginosa to gauge their exposure to HOCl inside phagosomes. Doses of reagent HOCl that killed most of the bacteria oxidized half the cells' GSH, producing mainly glutathione disulfide (GSSG) and other low-molecular-weight disulfides. Glutathione sulfonamide (GSA), a HOCl-specific product, was also formed. When neutrophils phagocytosed P. aeruginosa, half of the bacterial GSH was lost. Bacterial GSA production indicated that HOCl had reacted with the bacterial cells, oxidized their GSH, and was sufficient to be solely responsible for bacterial killing. Inhibition of NADPH oxidase and myeloperoxidase lowered GSA formation in the bacterial cells, but the bacteria were still killed, presumably by compensatory nonoxidative mechanisms. Of note, bacterial GSA formation in neutrophils from patients with cystic fibrosis (CF) was normal during early phagocytosis, but it was diminished at later time points, which was mirrored by a small decrease in bacterial killing. In conclusion, myeloperoxidase generates sufficient HOCl within neutrophil phagosomes to kill ingested bacteria. The unusual kinetics of phagosomal HOCl production in CF neutrophils confirm a role for the cystic fibrosis transmembrane conductance regulator in maintaining HOCl production in neutrophil phagosomes.
Processing Chinese relative clauses: An investigation of second-language learners from different learning contexts

Abstract The goal of this study is to examine the processing of Chinese relative clauses (RCs) through a self-paced reading task and to determine whether the learning environment plays a role in the second-language (L2) acquisition of RCs. We investigated two types of RCs (subject vs. object RCs) along with two positions in which a RC can occur (modifying a matrix subject noun phrase [NP] vs. a matrix object NP). Eighteen native speakers of Chinese and twenty-one L2 learners at an intermediate proficiency level participated in the study. Ten learners were students learning Chinese in the US (i. e., in a foreign-language context), whereas the other eleven learners were students studying Chinese in China (i. e., in a study-abroad context). The comprehension of sentences containing a RC and reading times (RTs) on the RC and the head noun (the segment immediately following the RC) were analyzed. The results show distinct patterns for the learners and the native speakers. The accuracy data reveals that the L2 learners in China performed better than the L2 learners in the US. Additionally, the L2 learners in China exhibited a processing speed advantage to the L2 learners in the US. The RT data highlighted important asymmetries in the L2 learners in the US and the native speakers, while the results were flat for the L2 learners in China. Specifically, L2 learners in the US took longer to read object RCs than subject RCs while the opposite pattern was obtained for the L1 speakers. Moreover, matrix-object-modifying RCs revealed shorter RTs than matrix-subject-modifying RCs for L2 learners in the US, whereas the opposite pattern was found for the L1 speakers. These findings are discussed in light of the Linear Distance Theory and the Structural Distance Theory (e. g., O’Grady 1997. Syntactic development. Chicago: University of Chicago Press). Overall, these results seem to provide support to the assumption that changes in syntactic processing happen as a result of exposure to the language environment (Cuetos et al. 1996. Parsing in different languages. In Manuel Carreias, Jose E. Garcia-Albea & Nuria Sebastien-Galles (eds.), Language processing in Spanish, 145–187. Mahwah, NJ: Erlbaum; Frenck–Mestre 2002.

Ellagic Acid Prevents Oxidative Stress, Inflammation, and Histopathological Alterations in Acrylamide-Induced Hepatotoxicity in Wistar Rats

Abstract The present study was designed to investigate the changes in rat liver tissue after administration of acrylamide (ACR) and ellagic acid (EA). The latter compound was applied for its strong antioxidant and anti-inflammatory properties. In the present study, 35 male Wistar rats were randomly divided into five equal groups. These groups were normal saline (NS), ACR (20 mg/kg), ACR + EA (10 and 30 mg/kg EA), and EA (30 mg/kg). At the end of the experiment, the rats were decapitated. Biochemical and histopathological studies were conducted on liver and serum samples. ACR administration significantly decreased hepatic GSH level, SOD, GPx, and CAT activity when compared to the NS group. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), nitric oxide (NO), protein carbonyl (PC), malondialdehyde (MDA), tumor necrosis factor alpha (TNF-α), and interleukin 1 beta (IL-1β) levels increased as a result of ACR administration. Administration of EA (more potently at a dose of 30 mg/kg) resulted in a significant reversal of biochemical, inflammatory, and hepatic markers in ACR-intoxicated rats. These biochemical and inflammatory disturbances were supported by histopathological observations of the liver. Our results indicate that EA might be useful for the treatment of the hepatotoxicity induced by ACR via ameliorative effects on biochemical, oxidative stress, and inflammatory indices.
