Multifactorial study of the risk of prematurity at 32 weeks of gestation. I. A study of the frequency of 30 predictive characteristics

1. Preventive methods are nessary It is impossible to solve this problem with curative methods only, as, even with the best care, treatment o£ prematures reduces mortality, but does not eliminate the consequences of the premature birth. It is therefore necessaty to turn to preventive methods. But it is not possible to take preventive measures against an unforeseeable accident. The research and improvement of prognostic methods should now be our main concern. The aim is to be able to predict the risk of a premature birthlong before it occurs.Our technique is a scoring method. Of all the cases being supervised in an antenatal care program, we wish to isolate those with the highest risk of prematurity and apply suitable preventive therapy.
Human Leukocyte Antigens B8-DRB1*03 in Pediatric Patients With Nephropathia Epidemica Caused by Puumala Hantavirus

In adults, HLA haplotype B8-DRB1*03 is clearly associated with a severe clinical course of nephropathia epidemica caused by Puumala hantavirus. We investigated whether the same applies in pediatric patients. This HLA haplotype was found in 20 of 39 (51%) of the patients, a significantly higher figure than in the Finnish population (19%). There were, however, no significant differences in the clinical picture between patients with and without HLA B8-DRB1*03.
Modeling the Effect of Ionic Dissociation on Charge Transport in Transformer Oil

Transformer oil is one of the most important and widely used of all dielectric liquids. Significant research into the insulating properties of transformer oil has been carried out. Much of this work has focused on the development of streamers, and how they can result in the electrical breakdown of the oil. Due to the complex nature of transformer oil no universally accepted model describing streamer initiation and propagation has emerged. In this paper, a model is developed which explores the role played by electric field dependent ionic dissociation in the initiation and propagation of streamers in transformer oil. This model couples the electrodynamics of charge transport to thermal enhancement in transformer oil. Using the COMSOL Multiphysics software application and the finite element method, the model is solved to show that ionic dissociation alone will not lead to a high enough temperature rise to initiate a streamer in transformer oil.

Changes in serum cartilage marker levels indicate altered cartilage metabolism in families with the osteoarthritis-related type II collagen gene COL2A1 mutation.

OBJECTIVE The Arg5l9-Cys mutation in type II collagen results in severe, precocious familial osteoarthritis (OA) in 100% of carriers within the first 3 decades of life. The carrier population provided a well-defined patient population for the study of serum markers of familial OA with respect to pathogenesis, diagnosis, and prognosis. METHODS Serum was obtained from 31 mutation-positive individuals and 16 mutation-negative individuals. OA severity was determined by clinical and radiologic assessments. Levels of serum cartilage oligomeric matrix protein (COMP), keratan sulfate (KS) epitope, the 846 epitope of aggrecan, and the C propeptide of type II collagen (CPII) were measured and were correlated with the radiologic findings. RESULTS COMP and KS levels, both of which have been suggested to be indicative of disturbed cartilage turnover, were significantly elevated in mutation-positive individuals and in the individuals with OA regardless of mutation status. There was no statistically significant difference between mutation-positive, mutation-negative, OA-positive, and OA-negative individuals with respect to serum concentrations of epitope 846 or CPII, both of which are putative markers of cartilage repair. CONCLUSION Study of the macromolecular constituents of cartilage released into serum in subjects with familial OA revealed altered metabolism in OA, as demonstrated by elevated COMP and KS levels. Other constituents, the 846 epitope and CPII, were not altered, indicating dissociation of cartilage anabolism and breakdown. Future sequential studies will provide an opportunity to define biochemical changes as familial OA develops and to monitor therapeutic responses.

Generational difference of refractive error and risk factors in the Handan Offspring Myopia Study.

PURPOSE To report the refractive error difference (RED) between parents and their children, and its risk factors, in a rural area of China. METHODS Children (6-17 years) and their parents (36.2 ± 4.1 years) from the Handan Offspring Myopia Study (HOMS) were enrolled. Cycloplegic autorefraction (cyclopentolate 1%, Topcon KR8800) of the children and noncycloplegic autorefraction of their parents were assessed. A detailed vision-based questionnaire was also completed. Refractive error difference was defined as the difference between the parental spherical equivalent (SE) and their children's SE. Generational myopic shift was defined as the estimated RED when a child would be 18 years old according to a prediction model. RESULTS Three hundred fifty-six pairs of parents and 585 children were enrolled. The RED (median, quartiles) increased from -1.33 (-1.99, -0.98) diopters (D) in children aged 6 to 7 years to 0.81 (-0.16, 2.28) D in children aged 16 to 17 years. The children's SE was predicted to approach the parental SE at 14 years of age. Moreover, the children's estimated myopic shift would be 1.03 D. Multiple linear regression revealed that older children (β = 0.23 D/y, P < 0.0001) and girls (β = 0.24, P = 0.01) tended to have a higher RED. CONCLUSIONS In this rural Chinese population, the children's refraction was estimated to be similar to the parental refraction at 14 years of age. Moreover, the generational myopic shift was estimated to be approximately 1 D at 18 years of age. These data suggest that the generational difference reflects the increasing prevalence of myopia in the younger generation, which is likely due to changes in environmental exposure.
Investor Sentiment, Accruals Anomaly, and Accruals Management

This study examines the effect of investor sentiment on the accruals anomaly. We find that for small stocks mispricing per unit of accruals is greater in high sentiment periods as compared with low sentiment periods. This result is consistent with the notion that in high sentiment periods individual investors pay less attention toward understanding the accruals and cash flow components of earnings. This effect is observed primarily for small stocks because these stocks are more likely to be followed by individual investors, who tend to have limited attention. We also find that for small stocks reported accruals are greater during high sentiment periods as compared with low sentiment periods, suggesting that managers exploit the greater overvaluation per unit of accruals during high sentiment periods.
The drivers for cloud-based virtual learning environment: Examining the moderating effect of school category

Purpose The purpose of this paper is to verify the moderating effects of school category based on the self-determination theory (SDT) in cloud-based virtual learning environment (VLE) acceptance. Design/methodology/approach Two phases of national surveys were conducted using a random sampling technique. The research model was tested empirically using 608 samples of primary and secondary school teachers. Findings The full model supports significant effects of autonomy, competence, and relatedness on trust, knowledge sharing attitude and behavioral intention except the autonomy-attitude and relatedness-behavioral intention relationships. In primary school, 61, 24.1, 52.1, and 41.1 percent of variances whereas, in secondary school, 57.4, 31.5, 48.6, and 37.5 percent of variances in instructional effectiveness, behavioral intention, knowledge sharing attitude, and trust in VLE website were explained. There are significant moderating effects of category of school in all causal relationships except the autonomy-knowledge sharing attitude relationship. Practical implications There are several useful theoretical and practical implications for scholars and practitioners including Ministry of Education, FrogAsia, etc. Social implications The findings may enhance education quality for societal change. Originality/value Unlike most studies which focused on TAM, UTAUT, etc., this study investigated the effects of SDT on attitude in sharing knowledge, trust in website and instructional effectiveness. Instead of studying gender differences, this study examined the school category differences.
The effects of running and of inhibiting adult neurogenesis on learning and memory in rats

The presence of ongoing adult neurogenesis within the highly plastic hippocampal circuitry poses questions as to the relevance of new neurons to learning and memory. Correlational and causal evidence suggests that some, but not all, hippocampal tasks involve the new neurons. The evidence with regard to spatial learning in the water maze, one of the most commonly used hippocampal tasks, is contradictory. In this study we examined the effects of irradiation‐induced reduction in neurogenesis on spatial learning and another standard hippocampal task, contextual fear conditioning, in rats that experienced normal cage conditions or voluntary running. The results indicate that reduced neurogenesis had little effect on spatial learning but severely impaired contextual fear conditioning. It was suggested that compensatory mechanisms within the hippocampus may have contributed selectively to sparing of spatial function. Performance on the fear conditioning task was weakly related to enhanced neurogenesis or running. The results improve our understanding of the functional role of adult neurogenesis in behaving animals.
Two Commonly Used Methods for Exposure—Adverse Events Analysis: Comparisons and Evaluations

The purpose of this study is to compare and evaluate logistic regression and time‐to‐event analysis, 2 commonly used methods for exposure—adverse event (AE) analyses. An AE data set selected from clinical trials is analyzed by both methods and the results are compared. The parameter estimates, odds ratios for logistic regression, and hazard ratios for time‐to‐event analysis for each AE are compared and further analyzed. In a data set involving 822 patients, 25 AEs are analyzed. A linear relationship is demonstrated between the parameter estimates from the 2 methods and between the odds ratios and hazard ratios. The small differences between the 2 analyses are related to the lower rate of the events and the weaker effects of the risk factors. Although the 2 methods can make predications for the risks, the severity, duration, and recurrence are not well defined. AE time profiles showing the onset, duration, and offset of AEs are important for risk assessment and management. Both analyses can provide information about exposure—AE relationship, and the results from the 2 analyses are consistent in most cases. One should not use the logistic model when length of follow‐up varies because of biased estimates. The application of the 2 methods should be combined with AE profiling.
Comparison of scales used to quantitate the sense of effort to breathe in patients with chronic obstructive pulmonary disease.

Several different scaling techniques, i.e., Borg category (BC) and visual analogue (VA) scales have been used to quantitate the intensity of the respiratory sensations elicited during exercise, but their relationship is unclear. Six subjects with stable chronic obstructive lung disease (FEV1 = 1.2 +/- 0.1 SE L) simultaneously rated the sense of effort to breathe with both BC and VA scales during progressive, maximal exercise tests performed three to five times on a cycle ergometer. The VA scores correlated linearly with minute ventilation in all subjects in all trials (r = 0.98 +/- 0.01), and when converted to common units (i.e., Z scores) correlated closely with simultaneous scores obtained using the Borg scale (r = 0.99 +/- 0.01). Furthermore, VA scores varied minimally over several trials. Coefficient of variation for the maximal VA scores was 6 +/- 1%, which was similar to the variation in maximal Borg score (i.e., 3 +/- 1%). We conclude that the visual analogue scale is reproducible and correlates closely with the Borg score when scaling the sense of effort to breathe during exercise in subjects with stable chronic obstructive pulmonary disease.
Cardiovascular disease risk among women living with HIV in North America and Europe

Purpose of review To examine the epidemiology and mechanistic underpinnings of heightened cardiovascular disease (CVD) risk among women living with HIV (WLHIV) in North America and Europe. Recent findings WLHIV in North America and Europe exhibit high CVD incidence rates, which are at par with those of compatriot men living with HIV. Compared with uninfected women, WLHIV in these regions face a 2–4-fold increased relative risk for myocardial infarction, stroke, and heart failure. HIV-associated CVD risk is fuelled by a negative synergy of traditional cardiometabolic risk factors and heightened systemic immune activation/inflammation. Among WLHIV, female sex and endogenous sex hormone production influence both traditional cardiometabolic risk factors and patterns of systemic immune activation/inflammation. WLHIV in North America and Europe may also experience heightened CVD risk in relation to a relatively increased prevalence of behavioral and psychosocial CVD risk factors, coupled with suboptimal therapeutic targeting of known traditional cardiometabolic risk factors. Summary Additional research on sex-specific mechanisms of HIV-associated CVD – based not only out of North America and Europe but also and especially out of Africa, Asia, and South America – will inform the development of CVD prediction algorithms and prevention guidelines clinically relevant to the approximately 17 million women aging with HIV globally.
Reducing Preventable Emergency Department Utilization and Costs by Using Community Health Workers as Patient Navigators

Primary care-related emergency department (PCR-ED) utilization, including for conditions that are preventable or treatable with appropriate primary care, is associated with decreased efficiency of and increased costs to the health system. Many PCR-ED users experience actual or perceived problems accessing appropriate, ongoing sources of medical care. Patient navigation, an intervention used most often in the cancer care continuum, may help to address these barriers among medically underserved populations, such as those who are low income, uninsured, publicly insured, or recent U.S. immigrants. We examined a patient navigation program designed to promote appropriate primary care utilization and prevent or reduce PCR-ED use at Memorial Hermann Health System in Houston, Texas. The intervention is facilitated by bilingual, state-certified community health workers (CHWs) who are trained in peer-to-peer counseling and connect medically underserved patients with medical homes and related support services. The CHWs provide education about the importance of primary care, assist with appointment scheduling, and follow up with patients to monitor and address additional barriers. Our study found that the patient navigation intervention was associated with decreased odds of returning to the ED among less frequent PCR-ED users. Among patients who returned to the ED for PCR reasons, the pre/post mean visits declined significantly over a 12-month pre/post-observation period but not over a 24-month period. The savings associated with reduced PCR-ED visits were greater than the cost to implement the navigation program. Our findings suggest that an ED-based patient navigation program led by CHWs should be further evaluated as a tool to help reduce PCR-ED visits among vulnerable populations.
Microtubule plus-end conformations and dynamics in the periphery of interphase mouse fibroblasts.

The plus ends of microtubules (MTs) alternate between phases of growth, pause, and shrinkage, a process called "dynamic instability. " Cryo-EM of in vitro-assembled MTs indicates that the dynamic state of the plus end corresponds with a particular MT plus-end conformation. Frayed ("ram's horn like"), blunt, and sheet conformations are associated with shrinking, pausing, and elongating plus ends, respectively. A number of new conformations have recently been found in situ but their dynamic states remained to be confirmed. Here, we investigated the dynamics of MT plus ends in the peripheral area of interphase mouse fibroblasts (3T3s) using electron microscopical and tomographical analysis of cryo-fixed, freeze-substituted, and flat-embedded sections. We identified nine morphologically distinct plus-end conformations. The frequency of these conformations correlates with their proximity to the cell border, indicating that the dynamic status of a plus end is influenced by features present in the periphery. Shifting dynamic instability toward depolymerization with nocodazole enabled us to address the dynamic status of these conformations. We suggest a new transition path from growth to shrinkage via the so-called sheet-frayed and flared ends, and we present a kinetic model that describes the chronology of events taking place in nocodazole-induced MT depolymerization.
Community detection based on social interactions in a social network

Recent research has involved identifying communities in networks. Traditional methods of community detection usually assume that the network's structural information is fully known, which is not the case in many practical networks. Moreover, most previous community detection algorithms do not differentiate multiple relationships between objects or persons in the real world. In this article, we propose a new approach that utilizes social interaction data (e.g., users' posts on Facebook) to address the community detection problem in Facebook and to find the multiple social groups of a Facebook user. Some advantages to our approach are (a) it does not depend on structural information, (b) it differentiates the various relationships that exist among friends, and (c) it can discover a target user's multiple communities. In the experiment, we detect the community distribution of Facebook users using the proposed method. The experiment shows that our method can achieve the result of having the average scores of Total‐Community‐Purity and Total‐Cluster‐Purity both at approximately 0.8.
Acoustic Properties of Different Cartilage Reconstruction Techniques of the Tympanic Membrane

Objectives/Hypothesis The use of cartilage in reconstruction of the tympanic membrane has been established especially in cases such as tubal dysfunction and adhesive processes. Cartilage offers the advantage of higher mechanical stability compared with membranous transplants but may alter the acoustic transfer characteristics of the graft. Apart from material properties, it can be assumed that, also, the microsurgical reconstruction technique might influence the sound transmission properties of the reconstructed tympanic membrane. The purpose of the study was to investigate the acoustic transfer characteristics of different cartilage transplants being typically used in different reconstruction techniques of the tympanic membrane.
