Acute reperfusion intramyocardial hemorrhage leads to regional chronic iron deposition in the heart

Intramyocardial hemorrhage commonly occurs in large reperfused myocardial infarctions. However, its long-term fate remains unexplored. We hypothesized that acute reperfusion intramyocardial hemorrhage leads to chronic iron deposition

Increasing Pediatric Hearing Aid Use: Considerations for Clinical Practice

Purpose: Hearing aid use can be variable for young children, and inconsistent wear time can undermine spoken language development. This study explored the effectiveness of hearing aid data logging (DL) awareness and coaching sessions on increasing hours of hearing aid use. We also collected qualitative data on challenges participants experienced managing hearing aid use. Method: We used a single-subject design that included three conditions, during a 6-week period, in the same order for each participant. Condition A was baseline, Condition B was DL monitoring alone, and Condition C was remote coaching calls plus DL monitoring. Results: Hours of hearing aid use increased for each child from baseline to the end of the study, ranging from 1.19 to 4.4 hr. Mothers reported that the coaching calls were beneficial and helped them identify and problem-solve issues. Conclusions: Parents were able to increase hours of hearing aid use with DL awareness and coaching support. Tele-audiology offers an opportunity to provide parents with more frequent support that can be individualized based on their situation, challenges, and family needs

Temporal repeatability of behaviour in a lizard: implications for behavioural syndrome studies

It is well established that, across taxa, individuals within populations exhibit consistent differences in their behaviour across time and/or contexts. Further, the functional coupling of traits may result in the formation of a behavioural syndrome. Despite extensive evidence on the existence of consistent among-individual differences in behaviour and behavioural syndromes in the animal realm, these findings are predominately based upon short-term assessments, leading to questions regarding their stability over longer periods. Understanding if these estimates are temporally stable would allow predictions of individual behaviour to be made using short-term repeated measures. Here, we used 57 adult male delicate skinks (Lampropholis delicata) to evaluate the stability of behavioural variation observed both among (animal personality and behavioural plasticity) and within individuals (behavioural predictability), as well as behavioural syndromes, across short (four weeks) and long (five months) timeframes. To do so, we repeatedly assayed activity, exploration, and boldness five times per each individual. Overall, our study revealed complex patterns of behavioural variation and trait (co)variation over time. Activity was always repeatable across time intervals, whereas behavioural differences among individuals in exploration and boldness were not consistent. Yet a behavioural syndrome between activity and exploration was detected at both shorter and longer temporal scales, suggesting that syndrome structure in these traits does not vary as a function of time. Our findings indicate that, at least for some traits (e.g. activity) and studies, short-term measures may be adequate in serving as a proxy for long-term variation in individual behaviour, and to reveal the existence of behavioural syndromes at the population level

Prevalence of childhood obesity in schools of Northern Greece

Prevalence of obesity in 592 Greek pupils (7-15 years old) was investigated. Body Mass Index (BMI) was calculated and percentages of overweight and obese children in age groups were assessed. High percentage of Greek children is overweight and obese. Comparison of BMI between schools of Thessaloniki center and the suburbs and between boys and girls showed no statistically significant difference

Speed control of a five-phase induction motor drive using modified super-twisting algorithm

The present work proposes an alternative for the inner current control based on the modified super-twisting algorithm with time delay estimation. Simulation results were carried out to verify the performance of the proposed robust control strategy for a five-phase induction motor drive. A stability analysis is also presented.CONACYT – Consejo Nacional de Ciencia y TecnologíaPROCIENCI

Degradation and mineralization of 4-tert-butylphenol in water using Fe-doped TiO2 catalysts

In the present work, the photocatalytic degradation and mineralization of 4-tert-butylphenol in water was studied using Fe-doped TiO2 nanoparticles under UV light irradiation. Fe-doped TiO2 catalysts (0.5, 1, 2 and 4 wt.%) were prepared using wet impregnation and characterized via SEM/EDS, XRD, XRF and TEM, while their photocatalytic activity and stability was attended via total organic carbon, 4-tert-butyl phenol, acetic acid, formic acid and leached iron concentrations measurements. The effect of H2O2 addition was also examined. The 4% Fe/TiO2 demonstrated the highest photocatalytic efficiency in terms of total organic carbon removal (86%). The application of UV/H2O2 resulted in 31% total organic carbon removal and 100% 4-t-butylphenol conversion, however combining Fe/TiO2 catalysts with H2O2 under UV irradiation did not improve the photocatalytic performance. Increasing the content of iron on the catalyst from 0.5 to 4% considerably decreased the intermediates formed and increased the production of carbon dioxide. The photocatalytic degradation of 4-tert-butylphenol followed pseudo-second order kinetics. Leaching of iron was observed mainly in the case of 4% Fe/TiO2, but it was considered negligible taking into account the iron load on catalysts. The electric energy per order was found in the range of 28–147 kWh/m3/order and increased with increasing the iron content of the catalyst

Null Models of Economic Networks: The Case of the World Trade Web

In all empirical-network studies, the observed properties of economic networks are informative only if compared with a well-defined null model that can quantitatively predict the behavior of such properties in constrained graphs. However, predictions of the available null-model methods can be derived analytically only under assumptions (e.g., sparseness of the network) that are unrealistic for most economic networks like the World Trade Web (WTW). In this paper we study the evolution of the WTW using a recently-proposed family of null network models. The method allows to analytically obtain the expected value of any network statistic across the ensemble of networks that preserve on average some local properties, and are otherwise fully random. We compare expected and observed properties of the WTW in the period 1950-2000, when either the expected number of trade partners or total country trade is kept fixed and equal to observed quantities. We show that, in the binary WTW, node-degree sequences are sufficient to explain higher-order network properties such as disassortativity and clustering-degree correlation, especially in the last part of the sample. Conversely, in the weighted WTW, the observed sequence of total country imports and exports are not sufficient to predict higher-order patterns of the WTW. We discuss some important implications of these findings for international-trade models.Comment: 39 pages, 46 figures, 2 table

Antibiotic Stewardship Among Primary Care Providers In Mississippi

The World Health Organization states antimicrobial resistance is the ability of a microorganism to stop an antimicrobial from working which results in ineffective treatment and persistent infections. The Center for Disease Control and Prevention (CDC, 2017) reported that in the year 2015, 269.4 million antibiotic prescriptions were written in the outpatient setting, and approximately 30% of antibiotics written are unwarranted. Of those cases, most patients receive an antibiotic related to acute uncomplicated bronchitis, pharyngitis, or rhinosinusitis. The CDC reported that Americans spend nearly $11 billion yearly on antibiotics alone. However, up to 50% of all antibiotics prescribed are not indicated or optimally effective which eventually leads to resistance. Antibiotic resistant infections are associated with loss of productivity, poorer health outcomes, and greater healthcare costs. The CDC launched The Get Smart: Know When Antibiotics Work campaign in 2003 which aimed to direct appropriate antibiotic use (CDC, 2017). Within this campaign, the CDC provides outpatient regarding condition, epidemiology, diagnosis, and management for providers to follow for appropriate prescription. The purpose of this study was to determine if primary care providers in Mississippi are following the CDC Adult Treatment Recommendations for antibiotic use in the treatment of acute uncomplicated bronchitis, streptococcal pharyngitis, and acute unspecified pharyngitis (CDC, 2016). The researchers collected data in six rural clinics across Mississippi. This study consisted of a quantitative, retrospective chart review with descriptive statistics. A convenience sampling of 582 charts were obtained for the retrospective review. For data collection, the researchers used a data collection tool which included information related to age, gender, insurance, title o f provider, and diagnoses related to the current research and CDC Adult Treatment Recommendations. Prior to conducting the study, consent was obtained from the Institutional Review Board (IRB) at the Mississippi University for Women. After data collection, data were subjected to analyses using descriptive statistics including, but not limited to, frequency, distributions, and percentages. The findings suggested that primary care providers in Mississippi are not consistently following the CDC Adult Treatment Recommendations for acute pharyngitis and uncomplicated bronchitis
