Factors Influencing the Use of Prenatal Care: A Systematic Review

Article type: Review article Background & aim: Prenatal care is a key strategy for achieving public health goals, primary healthcare objectives, and the Millennium Development Goals. The aim of this study was to investigate the factors influencing the use of prenatal care services in order to design suitable interventions and promote the use of these services. Methods: In this systematic quantitative literature review, studies published in years 2010-2014 were evaluated. For this purpose, two international electronic databases, i.e., Scopus and PubMed, were explored to find English-language articles by using relevant keywords; moreover, the reference lists of the articles were hand-searched. We reviewed all cross-sectional and prospective studies, which focused on factors associated with the use of prenatal care services within the specified period of time. Results: In total, 17 relevant articles were included in our review. The results showed that late initiation and inadequate use of prenatal care services are independently associated with multiple variables, including demographic characteristics, socioeconomic factors, predisposing cultural and religious factors, social support, factors related to healthcare providers, women’s awareness and attitude, unintended pregnancy, high-risk medical or obstetric history, and health behaviors. Conclusion: Based on the literature review, proper use of prenatal care cannot be achieved merely by establishing healthcare centers. Utilization of maternal health services may be achieved and improved via developing socioeconomic factors and addressing patients' basic needs including education and financial independence.

Forecasting the behavior of an elderly using wireless sensors data in a smart home

In this paper, the ability to determine the wellness of an elderly living alone in a smart home using a lowcost, robust, flexible and data driven intelligent system is presented. A framework integrating temporal and spatial contextual information for determining the wellness of an elderly has been modeled. A novel behavior detection process based on the observed sensor data in performing essential daily activities has been designed and developed. The developed prototype is used to forecast the behavior and wellness of the elderly by monitoring the daily usages of appliances in a smart home. Wellness models are tested at various elderly houses, and the experimental results are encouraging. The wellness models are updated based on the time series analysis. & 2013 Elsevier Ltd.

Patient Anxiety and Depression Moderate the Effects of Increased Self-management Knowledge on Physical Activity: A Secondary Analysis of a Randomised Controlled Trial on Health-Mentoring in COPD.

OBJECTIVE
Anxiety and depression are common comorbidities in people with chronic obstructive pulmonary disease (COPD). While these comorbidities could potentially lead to a higher motivation to learn about self-management, they could also inhibit patients from translating this knowledge into appropriate self-management behaviours. This paper explores the moderating effects of anxiety and depression on a health-mentoring intervention, focusing on mechanisms of change (mediation).


METHODS
182 COPD patients participated in an RCT, with anxiety and depression assessed by the Hospital Anxiety and Depression Scale (HADS), self-management knowledge by the Partners in Health Scale, and spontaneous physical activity using accelerometers, all measured at baseline, 6 and 12 months. The moderated mediation model tested the intervention's effect on physical activity, mediated via changes in self-management knowledge, at different levels of anxiety and depression.


RESULTS
Knowledge mediated the effect of the intervention on changes in physical activity only for participants reporting low levels of anxiety or depression. Both acted as moderators: Increased knowledge led to more physical activity among participants reporting low anxiety or depression and to less activity among highly anxious or depressed participants.


CONCLUSION
Although health-mentoring interventions can be an effective tool to increase knowledge and physical activity among COPD patients, it is essential to take anxiety and depression into account, as increased knowledge may have detrimental effects in highly anxious or depressed participants. This suggests that patients with elevated anxiety or depression may need to be treated appropriately before engaging in chronic disease self-management interventions.
Unilateral frontalis sling for the surgical correction of unilateral poor-function ptosis.

PURPOSE
To evaluate the functional and cosmetic results after frontalis sling repair for unilateral ptosis associated with either poor levator function or synkinesis.


METHODS
Preoperative and postoperative photographs and records of 127 patients who underwent unilateral frontalis sling ptosis repair were retrospectively reviewed. An eyelid crease incision was used in all cases, with suturing of the sling material directly to tarsus.


RESULTS
Preoperative diagnosis for all patients was either unilateral poor-function blepharoptosis or ptosis associated with levator synkinesis. Underlying causes included 75 congenital, 13 posttraumatic, 11 congenital "jaw-winking," 10 cranial nerve III palsies, 9 myasthenia gravis, 5 chronic progressive external ophthalmoplegia, and 4 congenital "double-elevator" palsies. There was a mean follow-up of 11.6 months. Twenty-eight eyelids required reoperation: 11 for undercorrection, 6 for overcorrection with keratopathy, 2 for upper eyelid crease revision, 7 for correction of poor contour, 1 for a broken sling, and 1 for removal of an infected exposed polytetraflouroethylene sling. Lagophthalmos of greater than 2 mm was noted in 18 patients, 5 of whom had persistent keratopathy requiring reoperation. No other complications were reported, except for 1 suture granuloma. Good to excellent final postoperative eyelid height was achieved in 121 patients (95%) after all surgeries and with conscious recruitment of the frontalis muscle. A large majority of patients and/or parents expressed satisfaction with the final cosmetic result and were not bothered by any asymmetric lagophthalmos in downgaze or lack of a synchronous blink. However, 19 of 25 amblyopic patients were less satisfied with passive eyelid height as they failed to recruit the ipsilateral frontalis muscle to activate the sling during binocular viewing. In 17 of these 19 patients, good to excellent eyelid height could be achieved with conscious active brow elevation.


CONCLUSIONS
Unilateral sling provides good to excellent functional and cosmetic results in unilateral poor-function ptosis. However, patients with amblyopia usually require conscious effort to activate the frontalis muscle to achieve satisfactory eyelid height.
Why can LDA be performed in PCA transformed space?

PCA plus LDA is a popular framework for linear discriminant analysis (LDA) in high dimensional and singular case. In this paper, we focus on building a theoretical foundation for this framework. Moreover, we point out the weakness of the previous LDA based methods, and suggest a complete PCA plus LDA algorithm. Experimental results on ORL face image database indicate that the proposed method is more e6ective than the previous ones. ? 2002 Published by Elsevier Science Ltd on behalf of Pattern Recognition Society.
GENETIC VARIABILITY, CHARACTER ASSOCIATION AND GENETIC DIVERGENCE IN MUNGBEAN (VIGNA RADIATE L.WILCZEK

Genetic variability, correlation coefficient, path coefficient and genetic diversity were determined among fifty mungbean genotypes. There was a great deal of significant variation for all the characters among the genotypes. Considering genetic parameters high genotypic co-efficient of variation (GCV) was observed for no. of primary branches, seed yield per plant but no. of seed per pod and days to 80% maturity showed low GCV. In all the cases, phenotypic variances were higher than the genotypic variance. High heritability with low genetic advance in percent of mean was observed for days to 50% flowering suggesting non-additive gene effects for the expression of the character and selection for such trait might not be rewarding. High heritability with high genetic advance in percent of mean was observed for no. of primary branches per plant and a thousand seed weight indicating that this trait was under additive gene control and selection for genetic improvement for this trait would be effective. Seed yield per plant showed highest significant positive correlation with a thousand seed weight. It also has a significant positive correlation with seed per pod at genotypic level and a non-significant positive correlation with seed per pod at phenotypic level. Therefore, these traits could be important for the direct selection to improve yield. Total six clusters were formed for fifty genotypes. Considering group distance, cluster mean values, and other agronomic performances, inter genotypic crosses between G16 and G47; G16 and G13; G47 and G13: G21 and G19: G8 and G21, G21 and G35, G3 and G8, G3 and G35, G3 and G19, G8 and G19 might be suggested for future hybridization program.
Discounting and altruism to future decision-makers

Can a generation’s discounting of future generations’ consumption utilities be interpreted as “pure” altruism towards future generations, that is, a concern that these are better off according to their likewise forward-looking preferences? It turns out that the answer is positive for many but not all discount functions used in the economics literature. In particular, traditional exponential discounting is consistent with altruism towards the next generation, and “hyperbolic” discounting of the form used by Phelps and Pollak (1968) and Laibson (1997) is consistent with altruism to all future generations. More generally, we provide one sufficient and one necessary condition for a discount function to be consistent with altruism, and we establish a recursive functional equation which defines a one-to-one mapping between discounting and altruism.

Image Fusion Techniques and Quality Assessment Parameters for Clinical Diagnosis : A Review

Image fusion is a tool that serves to combine multi sensors images by using advanced image processing techniques. Particularly it serves best in medical diagnosis i.e. computed tomography (CT), magnetic resonance image (MRI), scan provides different types of information, by fusing them we can get accurate information for better clinical diagnosis. Transform domain image fusion methods such as wavelet transform, curvelet transform have its specific advantages while going for multi-sensors image fusion. Analysis is done to determine the image fusion algorithm which is more suitable for clinical diagnosis. Analysis is also done on image quality assessment parameters of image fusion. This paper presents a literature review on image fusion techniques and image quality assessment parameters such as Structural similarity index measure, laplacian mean squared error, mean squared error, Peak signal to noise ratio, entropy, structural content, Normalized cross correlation, Maximum difference, normalized absolute error. Comparison and effective use of all the techniques in image quality assessment is also

Not all age-related white matter hyperintensities are the same: a magnetization transfer imaging study.

PURPOSE
Our aim was to assess whether presumed histologic heterogeneity of age-related white matter hyperintensities (WMH) is reflected in quantitative magnetization transfer imaging measures.


MATERIALS AND METHODS
From a group of patients participating in a double-blind placebo-controlled multicenter study on the effect of pravastatin (PROSPER), we selected 56 subjects with WMH. WMH were classified as periventricular WMH (PVWMH) and deep WMH (DWMH). PVWMH were subclassified as irregular or smooth, depending on the aspect of their border. Signal intensity of WMH on T1-weighted images was scored as iso- or hypointense. The mean magnetization transfer ratio (MTR) value of different types of WMH was assessed and compared. As a control group, we selected 19 subjects with no or limited WMH.


RESULTS
Mean (SE) MTR of PVWMH (frontal, 31.2% [0.2%]; occipital, 32.2% [0.2%]) was lower than that of DWMH (33.7% [0.5%]). The mean MTR of frontal PVWMH (31.2% [0.2%]) was lower than that of occipital PVWMH (32.2% [0.2%]). Compared with occipital PVWMH, frontal PVWMH more often had a smooth lining (72% frontal versus 8% occipital) and an area with low signal intensity on T1-weighted images (76% frontal versus 35% occipital). MTR did not differ between smooth (31.1% [0.3%]) and irregular (31.6% [0.5%]) PVWMH.


CONCLUSION
Age-related WMH are heterogeneous, despite their similar appearance on T2-weighted images. By taking into account heterogeneity of age-related WMH, both in terms of etiology and in terms of severity of tissue destruction, one may obtain better understanding on the causes and consequences of these lesions.

Neural architectures optimization and genetic algorithms

The artificial neural networks (ANN) have proven their efficiency in several applications: pattern recognition, voice and classification problems. The training stage is very important in the ANN’s performance. The selection of the architecture of a neural network suitable to solve a given problem is one of the most important aspects of neural network research. The choice of the hidden layers number and the values of weights has a large impact on the convergence of the training algorithm. In this paper we propose a mathematical formulation in order to determine the optimal number of hidden layers and good values of weights. To solve this problem, we use genetic algorithms. The numerical results assess the effectiveness of the theorical results shown in this paper and computational experiments are presented, and the advantages of the new modelling.

Prospective Cohort Study of Nephrogenic Systemic Fibrosis in Patients With Stage 3-5 Chronic Kidney Disease Undergoing MRI With Injected Gadobenate Dimeglumine or Gadoteridol.

OBJECTIVE
The purpose of this study was to determine the incidence of nephrogenic systemic fibrosis (NSF) in patients with chronic kidney disease (CKD) and moderate-to-severe impairment of kidney function who had not previously been exposed to gadolinium-based contrast agents (GBCAs) or referred to undergo contrast-enhanced MRI with gadobenate dimeglumine or gadoteridol.


SUBJECTS AND METHODS
Two multicenter prospective cohort studies evaluated the incidence of unconfounded NSF in patients with stage 3 CKD (estimated glomerular filtration rate [eGFR] in cohort 1, 30-59 mL/min/1.73 m(2)) or stage 4 or 5 CKD (eGFR in cohort 2, < 30 mL/min/1.73 m(2)) after injection of gadobenate dimeglumine (study A) or gadoteridol (study B). A third study (study C) determined the incidence of NSF in patients with stage 4 or 5 CKD who had not received a GBCA in the 10 years before enrollment. Monitoring for signs and symptoms suggestive of NSF was performed via telephone at 1, 3, 6, and 18 months, with clinic visits occurring at 1 and 2 years.


RESULTS
For studies A and B, the populations evaluated for NSF comprised 363 and 171 patients, respectively, with 318 and 159 patients in cohort 1 of each study, respectively, and with 45 and 12 patients in cohort 2, respectively. No signs or symptoms of NSF were reported or detected during the 2 years of patient monitoring. Likewise, no cases of NSF were reported for any of the 405 subjects enrolled in study C.


CONCLUSION
To our knowledge, and consistent with reports in the literature, no association of gadobenate dimeglumine or gadoteridol with unconfounded cases of NSF has yet been established. Study data confirm that both gadoteridol and gadobenate dimeglumine properly belong to the class of GBCAs considered to be associated with the lowest risk of NSF.
Supporting insensitive mothers: the Vilnius randomized control trial of video-feedback intervention to promote maternal sensitivity and infant attachment security.

OBJECTIVE
This randomized control trial examined the effects of a short-term, interaction-focused and attachment-based video-feedback intervention (VIPP: video-feedback intervention to promote positive parenting). Design VIPP effect on mothers' sensitive responsiveness and infant-mother attachment security was evaluated in a sample (n = 54) of low sensitive, non-clinical, middle class Lithuanian mothers.


METHODS
Maternal sensitivity was assessed in a free play session with the Ainsworth's sensitivity scale, and attachment security was observed using the Attachment Q sort for home observations.


RESULTS
We found that the intervention mothers indeed significantly improved their sensitive responsiveness through participation in our VIPP. The effect size was large according to Cohen's criteria, d = 0.78. VIPP enhanced maternal sensitive responsiveness even when maternal age, educational level, depression, daily hassles, efficacy, infant gender, and infant negative and positive affect were controlled for. However, attachment security in the VIPP infants was not enhanced after the intervention, compared with the control infants, and the infants did not seem to be differentially susceptible to the increase in maternal sensitivity dependent on their temperamental reactivity.


CONCLUSION
We suggest that a relatively brief and low-cost programme can provide effective support for mothers who lack sensitivity in the interactions with their infants.

The comparability of the universalism value over time and across countries in the European Social Survey: exact vs. approximate measurement invariance

Over the last decades, large international datasets such as the European Social Survey (ESS), the European Value Study (EVS) and the World Value Survey (WVS) have been collected to compare value means over multiple time points and across many countries. Yet analyzing comparative survey data requires the fulfillment of specific assumptions, i.e., that these values are comparable over time and across countries. Given the large number of groups that can be compared in repeated cross-national datasets, establishing measurement invariance has been, however, considered unrealistic. Indeed, studies which did assess it often failed to establish higher levels of invariance such as scalar invariance. In this paper we first introduce the newly developed approximate approach based on Bayesian structural equation modeling (BSEM) to assess cross-group invariance over countries and time points and contrast the findings with the results from the traditional exact measurement invariance test. BSEM examines whether measurement parameters are approximately (rather than exactly) invariant. We apply BSEM to a subset of items measuring the universalism value from the Portrait Values Questionnaire (PVQ) in the ESS. The invariance of this value is tested simultaneously across 15 ESS countries over six ESS rounds with 173,071 respondents and 90 groups in total. Whereas, the use of the traditional approach only legitimates the comparison of latent means of 37 groups, the Bayesian procedure allows the latent mean comparison of 73 groups. Thus, our empirical application demonstrates for the first time the BSEM test procedure on a particularly large set of groups.
