Breastfeeding and later cognitive and academic outcomes.

OBJECTIVE
This study examines the associations between duration of breastfeeding and childhood cognitive ability and academic achievement over the period from 8 to 18 years using data collected during the course of an 18-year longitudinal study of a birth cohort of >1000 New Zealand children.


METHOD
During the period from birth to age 1 year, information was collected on maternal breastfeeding practices. Over the period from 8 to 18 years, sample members were assessed on a range of measures of cognitive and academic outcomes including measures of child intelligence quotient; teacher ratings of school performance; standardized tests of reading comprehension, mathematics, and scholastic ability; pass rates in school leaving examinations; and leaving school without qualifications.


RESULTS
Increasing duration of breastfeeding was associated with consistent and statistically significant increases in 1) intelligence quotient assessed at ages 8 and 9 years; 2) reading comprehension, mathematical ability, and scholastic ability assessed during the period from 10 to 13 years; 3) teacher ratings of reading and mathematics assessed at 8 and 12 years; and 4) higher levels of attainment in school leaving examinations. Children who were breastfed for >/=8 months had mean test scores that were between 0. 35 and 0.59 SD units higher than children who were bottle-fed. Mothers who elected to breastfeed tended to be older; better educated; from upper socioeconomic status families; were in a two-parent family; did not smoke during pregnancy; and experienced above average income and living standards. Additionally, rates of breastfeeding increased with increasing birth weight, and first-born children were more likely to be breastfed. Regression adjustment for maternal and other factors associated with breastfeeding reduced the associations between breastfeeding and cognitive or educational outcomes. Nonetheless, in 10 of the 12 models, fitted duration of breastfeeding remained a significant predictor of later cognitive or educational outcomes. After adjustment for confounding factors, children who were breastfed for >/=8 months had mean test scores that were between 0.11 and 0.30 SD units higher than those not breastfed.


CONCLUSIONS
It is concluded that breastfeeding is associated with small but detectable increases in child cognitive ability and educational achievement. These effects are 1) pervasive, being reflected in a range of measures including standardized tests, teacher ratings, and academic outcomes in high school; and 2) relatively long-lived, extending throughout childhood into young adulthood.
The convergence of medicine and neurotoxins: a focus on botulinum toxin type A and its application in aesthetic medicine--a global, evidence-based botulinum toxin consensus education initiative: part II: incorporating botulinum toxin into aesthetic clinical practice.

BACKGROUND
The new world of safe aesthetic injectables has become increasingly popular with patients. Not only is there less risk than with surgery, but there is also significantly less downtime to interfere with patients' normal work and social schedules. Botulinum toxin (BoNT) type A (BoNTA) is an indispensable tool used in aesthetic medicine, and its broad appeal has made it a hallmark of modern culture. The key to using BoNTA to its best effect is to understand patient-specific factors that will determine the treatment plan and the physician's ability to personalize injection strategies.


OBJECTIVES
To present international expert viewpoints and consensus on some of the contemporary best practices in aesthetic BoNTA, so that beginner and advanced injectors may find pearls that provide practical benefits.


METHODS AND MATERIALS
Expert aesthetic physicians convened to discuss their approaches to treatment with BoNT. The discussions and consensus from this meeting were used to provide an up-to-date review of treatment strategies to improve patient results. Information is presented on patient management and assessment, documentation and consent, aesthetic scales, injection strategies, dilution, dosing, and adverse events.


CONCLUSION
A range of product- and patient-specific factors influence the treatment plan. Truly optimized outcomes are possible only when the treating physician has the requisite knowledge, experience, and vision to use BoNTA as part of a unique solution for each patient's specific needs.
Development and validation of the pain treatment satisfaction scale (ptss): a patient satisfaction questionnaire for use in patients with chronic or acute pain

The purpose of this study was to develop and validate a measure of patient satisfaction for patients receiving treatment for either acute or chronic pain: the Pain Treatment Satisfaction Scale (PTSS). Development of the initial questionnaire included a comprehensive literature review and interviews with patients, physicians and nurses in the United States, Italy and France. After initial items were created, psychometric validation was run on responses from 111 acute pain and 89 chronic pain patients in the United States. Analyses included principal components factor analysis tests of reliability, clinical validity and confounding. The hypothesized structure of the questionnaire was supported by statistical analyses, and seven overlapping or inconsistent items were removed. The multi-item domains of the final PTSS included 39 items grouped in five dimensions: information (5 items); medical care (8 items); impact of current pain medication (8 items); satisfaction with pain medication which included the two subscales medication characteristics (3 items) and efficacy (3 items); and side effects (12 items). Internal consistency reliability coefficients were good (ranging from 0.83 to 0.92). The test-retest reliability coefficients (ranging from 0.67 to 0.81) were good for all dimensions except medication characteristics (0.55). All dimensions except medical care discriminated well according to pain severity. The satisfaction with efficacy dimension, hypothesized to change in the acute pain population, indicated good preliminary responsiveness properties (effect size 0.37; P<0.001). The PTSS is a valid, comprehensive instrument to assess satisfaction with treatment of pain based on independent modules that have demonstrated satisfactory psychometric performance.
Teens , Gender , and Self-Presentation in Social Media

This chapter is concerned with how teenage boys and girls present themselves through online social media such as Facebook, Twitter, blogs, and chat forums. Based on research conducted mostly in the United States, it describes and considers the implications of social media use, profile construction, visual and textual self-presentation, profile visibility, truthfulness, and other facets of teens’ self-presentation in relation to their gender.
Receiving treatment for common mental disorders.

OBJECTIVE
Anxiety and depressive disorders are widely prevalent, but patients are only treated in a minority of cases. In this study, the explanation of receiving mental health treatment is sought in predisposing and enabling characteristics and indicators for objective and self-perceived need.


METHODS
Cross-sectional analysis of data collected in the Netherlands Study of Depression and Anxiety (NESDA) among 743 persons with an anxiety and/or depression diagnosis as assessed by the CIDI. Receipt of mental health treatment was assessed in the face-to-face interview, as well as indicators of predisposing and enabling factors and variables evaluating need for care.


RESULTS
Of the total sample, 57% received treatment in the past 6 months in the general practice setting (50%) or the mental health care setting (14%). Younger patients, patients who evaluated their providers better on communicative abilities and patients who perceived mental health problems themselves had greater odds of having professional mental health contacts in the primary care setting. Confidence in professional help and higher severity of mental problems were associated with greater odds of having specialized mental health care.


CONCLUSION
Receiving help for common mental disorders depends not only on the objective need of the patient but also at least as much on the patients' own recognition that their problems have a mental health origin. Furthermore, in primary care especially, the patients' judgment of their providers' affective abilities may be decisive for being treated. For receiving specialized care, patients are also directed by their confidence in professional help.
IMAGE Resolution Enhancement by Using Discrete and Stationary Wavelet Decomposition

In this correspondence, the authors propose an image resolution enhancement technique based on interpolation of the high frequency subband images obtained by discrete wavelet transform (DWT) and the input image. The edges are enhanced by introducing an intermediate stage by using stationary wavelet transform (SWT). DWT is applied in order to decompose an input image into different subbands. Then the high frequency subbands as well as the input image are interpolated. The estimated high frequency subbands are being modified by using high frequency subband obtained through SWT. Then all these subbands are combined to generate a new high resolution image by using inverse DWT (IDWT). The quantitative and visual results are showing the superiority of the proposed technique over the conventional and state-of-art image resolution enhancement techniques.
Efficacy of telaprevir-based therapy in stable liver transplant patients with chronic genotype 1 hepatitis C.

UNLABELLED
 Background and rationale. The REPLACE study (NCT01571583) investigated telaprevir-based triple therapy in patients who have recurrent genotype 1 hepatitis C virus (HCV) infection following liver transplantation and are on a stable immunosuppressant regimen of tacrolimus or cyclosporin A. Patients received telaprevir 750 mg 8-hourly with pegylated interferon 180 ?g weekly and ribavirin 600 mg daily, followed by a further 36 weeks of pegylated interferon and ribavirin alone and 24 weeks of follow-up. Efficacy (sustained virological response [SVR] 12 weeks after last planned study dose), safety and tolerability of telaprevir throughout the study were assessed. Pharmacokinetics of telaprevir, tacrolimus and cyclosporin A were also examined.


RESULTS
In total, 74 patients were recruited. Overall, 72% (53/74; 95% CI: 59.9 to 81.5) of patients achieved SVR at 12 weeks following completion of treatment. Anticipated increases in plasma concentrations of tacrolimus and cyclosporin A occurred during telaprevir treatment and were successfully managed through immunosuppressant dose reduction and, for tacrolimus, reduced dosing frequency. Safety and tolerability of telaprevir-based triple therapy were generally comparable with previous data in non-transplant patients, although rates of reported anemia (55% [41/74]) were higher. Elevated plasma creatinine (46% [34/74]) was observed during REPLACE - consistent with the post-liver transplant population and the co-administered immunosuppressants.


CONCLUSION
Telaprevir-based triple therapy in patients with recurrent genotype 1 HCV infection following liver transplantation produced high rates of SVR. Therapeutic concentrations of immunosuppressants were maintained successfully through dose modification during telaprevir treatment.
A Hybrid Particle Swarm Optimization for Distribution State Estimation

This paper proposes a hybrid particle swarm optimization for a practical distribution state estimation. The proposed method considers nonlinear characteristics of the practical equipment and actual limited measurements in distribution systems. The method can estimate load and distributed generation output values at each node by minimizing the difference between measured and calculated voltages and currents. The feasibility of the proposed method is demonstrated and compared with an original particle swarm optimization based method on practical distribution system models. Effectiveness of the constriction factor approach of particle swarm optimization is also investigated. The results indicate the applicability of the proposed state estimation method to the practical distribution systems.
Photoluminescence mechanism of annealed ZnO/Zn/Al2O3 sandwich structures deposited on glass substrates

Abstract ZnO/Zn/Al 2 O 3 sandwich structures are grown on glass substrates by magnetron sputtering. The effect of Al 2 O 3 layers on optical properties of ZnO/Zn/Al 2 O 3 sandwich structures is investigated. Results indicated that as the deposition time of Al 2 O 3 increases, violet peak centered at 402 nm gradually shifted to 412 nm and the intensity firstly decreases and then increases. We discuss the intensity change and shift of violet peak relating to V Zn defects and the band alignment of ZnO/Zn/Al 2 O 3 sandwich structures, respectively. We proposed that ZnO/Zn/Al 2 O 3 sandwich structures can be approximately regarded as a quasiquantum-well-like structure. So the electron tunneling from Zn to Al 2 O 3 layer is suppressed and the photogenerated carriers can be confined in the Zn Fermi level. In order to further understand the effect of posttreatment on optical properties of samples, samples are annealed in vacuum at 350 °C for 1 h. PL emissions are weakened with the increase of Al 2 O 3 deposition time. Interestingly, at a same deposition condition, PL emissions are still improved after posttreatment. Combined Al 2 O 3 layer modulation with annealing treatment, steady PL properties can be effectively improved.

A randomized controlled trial of the efficacy and safety of electroanatomic circumferential pulmonary vein ablation supplemented by ablation of complex fractionated atrial electrograms versus potential-guided pulmonary vein antrum isolation guided by intracardiac ultrasound.

BACKGROUND
The study was conducted to compare relative safety and efficacy of pulmonary vein antrum isolation (PVAI) using intracardiac echocardiographic guidance and circumferential pulmonary vein ablation (CPVA) for atrial fibrillation (AF) using radiofrequency energy.


METHODS AND RESULTS
Sixty patients (81% men; 81% paroxysmal; age, 56+/-8 years) failing 2+/-1 antiarrhythmic drugs were randomly assigned to undergo CPVA (n=30) or PVAI (n=30) at 5 centers between December 2004 and October 2007. CPVA patients had circular lesions placed at least 1 cm outside of the veins. Ipsilateral veins were ablated en block with the end point of disappearance of potentials within the circular lesion. Left atrial roof line and mitral isthmus line were ablated without verification of block. For patients in AF postablation or with AF induced with programmed stimulation, complex fractionated electrograms were mapped and ablated to the end point of AF termination or disappearance of complex fractionated electrograms. PVAI did not include complex fractionated electrogram ablation. Esophageal temperature was monitored and kept within 2 degrees C of baseline or under 39 degrees C. Success was defined as absence of atrial tachyarrhythmias (AF/AT) off antiarrhythmic drugs. There was no difference between CPVA and PVAI regarding to baseline variables, catheter used, duration of the procedure, or RF delivery. Fluoroscopy time was longer with PVAI (54+/-17 minutes versus 77+/-18 minutes, P=0.0001). No significant complications occurred in either arm. PVAI was more likely to achieve control of AF/AT off antiarrhythmic drugs (57% versus 27%, P=0.02) at 2+/-1 years of follow-up.


CONCLUSIONS
A single PVAI procedure is more likely to result in freedom from AF/AT off antiarrhythmic drugs than CPVA supplemented by complex fractionated electrogram ablation in select patients.
Custom IC for Ultra-low Power RF Energy Harvesting

This paper presents a custom IC that provides an efficient interface between an ultra-low power RF rectifying antenna (rectenna) source and a microbattery, with the goal of maximum power harvesting. The energy harvester IC uses current-starved circuitry, a non-overlapping gate-drive, and a sub-threshold current source to achieve a nominal supply current in the 200 nA range for VDD = 2.5 V. Experimental results are given with the IC harvesting energy from a 1.93 GHz patch rectenna to a battery with voltages ranging from 2.5 V to 4.15 V. Overall conversion efficiency including all control losses is demonstrated at over 35 % at an input power of just 1.5 ¿W and at over 70 % at input power levels over 30 ¿W. The IC is fabricated in a 5 V, 0.35 ¿m CMOS process. Although the IC was designed for RF energy harvesting, the low power boost converter can be applied to other power sources such as wind, vibrations, and temperature.
[Establishment of an Animal Based Therapy at a University Hospital for Psychiatry: Results of a Preliminary Study and Future Prospects].

Objective: Dogs have been integrated in human society over centuries. This process has selected unique social and communicative skills. Dogs are thus able to represent social substitutes for human counterparts in cases of social withdrawal. Furthermore, dogs act as "social catalysts" in promoting interhuman encounters. Thus, the integration of dogs in psychotherapeutic concepts addressing social and interpersonal deficits may be of special interest. Methods: The present investigation reports the results of a pilot study to establish animal-assisted therapy (dogs) at a psychiatric department. The animal-assisted intervention straddled the following areas: (1) contact making, communication and orientation to needs, (2) recreation and play, (3) outward orientation, (4) release and farewell. The sample comprised 22 subjects. Results: The results demonstrated in particular that the animal-assisted intervention significantly promoted unspecific aspects of positive affectivity and wellbeing. Evaluation of the overall acceptance of the dog on the psychiatric ward revealed very positive feedback. Conclusions: We conclude that animal-assisted therapies represent a significant enchrichment of the therapeutic context, that may be used to enhance the patients' openness and adherence to conventional therapies.
Pulmonary oedema following venous air embolism during transsphenoidal pituitary surgery

Venous air embolism (VAE) is a well known complication in procedures where the operative field is above the level of the heart. Acute pulmonary oedema after a large air embolus occurring during neurosurgery is also a recognized phenomenon. However, pulmonary oedema following repeated episodes of VAE in sublabial transsphenoidal (SLTS) surgery for pituitary adenoma has never been reported. We describe a case of VAE in a 65 year old male undergoing SLTS surgery for pituitary adenoma. Following this, the patient had pulmonary oedema which resolved on supportive treatment. Pulmonary oedema as a result of VAE may go unrecognised intraoperatively but can lead to a significant postoperative morbidity. Early suspicion and recognition of VAE and institution of aggressive treatment will help to avoid fatal consequences.
Lipase-catalyzed biodiesel production and quality with Jatropha curcas oil: exploring its potential for Central America

BACKGROUND
Extensive native Jatropha curcas L. (Jatropha) crop areas have been planted in Central America marginal lands since 2008 as a non-edible prospective feedstock alternative to high-value, edible palm oil. Jatropha biodiesel is currently exclusively produced in the region at commercial scale utilizing alkaline catalysts. Recently, a free, soluble Thermomyces lanuginosus (TL) 1,3 specific lipase has shown promise as biocatalyst, reportedly yielding up to 96 % ASTM D6751 compliant biodiesel after 24 h transesterification of soybean, canola oils and other feedstocks. Biodiesel conversion rate and quality of enzymatically catalyzed transesterification of Jatropha oil was evaluated. Two lipases: free, soluble TL and immobilized Candida antarctica (CA) catalyzed methanolic transesterification of crude Jatropha and refined palm oil.


RESULTS
Jatropha yields were similar to palm biodiesel with NaOH as catalyst. After 24 h transesterification, Jatropha (81 %) and palm oil (86 %) biodiesel yields with TL as catalyst were significantly higher than CA (<70 %) but inferior to NaOH (>90 %). Enzymatic catalysts (TL and CA) produced Jatropha biodiesel with optimum flow properties but did not complied with ASTM D6751 stability parameters (free fatty acid content and oil stability index).


CONCLUSIONS
Biodiesel production with filtered, degummed, low FFA Jatropha oil using a free liquid lipase (TL) as catalyst showed higher yielding potential than immobilized CA lipase as substitute of RBD palm oil with alkaline catalyst. However, Jatropha enzymatic biodiesel yield and stability were inferior to alkaline catalyzed biodiesel and not in compliance with international quality standards. Lower quality due to incomplete alcoholysis and esterification, potential added costs due to need of more than 24 h to achieve comparable biodiesel yields and extra post-transesterification refining reactions are among the remaining drawbacks for the environmentally friendlier enzymatic catalysis of crude Jatropha oil to become an economically viable alternative to chemical catalysis.
Fast topology estimation for image mosaicing using adaptive information thresholding

Over the past decade, several image mosaicing methods have been proposed in robotic mapping and remote sensing applications. Owing to rapid developments in obtaining optical data from areas beyond human reach, there is a high demand from different science fields for creating large-area image mosaics, often using images as the only source of information. One of the most important steps in the mosaicing process is motion estimation between overlapping images to obtain the topology, i.e., the spatial relationships between images. In this paper, we propose a generic framework for feature-based imagemosaicing capable of obtaining the topology with a reduced number of matching attempts and of getting the best possible trajectory estimation. Innovative aspects include the use of a fast image similarity criterion combined with a Minimum Spanning Tree (MST) solution, to obtain a tentative topology and information theory principles to decide when to update trajectory estimation. Unlike previous approaches for large-areamosaicing, our framework is able to naturally deal with the cases where time-consecutive images cannot be matched successfully, such as completely unordered sets. This characteristic also makes our approach robust to sensor failure. The performance of the method is illustrated with experimental results obtained from different challenging underwater image sequences. © 2012 Elsevier B.V. All rights reserved.
