Published: August 2018

Purpose Early diagnosis and treatment of slipped capital femoral epiphysis (SCFE) is important to prevent slip progression and avoid complications. We sought to determine if MRI findings in patients with unilateral SCFE could indicate ‘pre-slip’ or predict future SCFE in the contralateral hip. Methods A prospective study evaluated patients with unilateral SCFE over a two-year period. MRI of the asymptomatic hip was performed within the perioperative period. Patients were followed with radiographs until a contralateral slip occurred or until physeal closure. Demographics, clinical stability, severity, posterior slope angle (PSA), modified Oxford Bone Score (mOBS) and patency of the triradiate cartilage were recorded and statistical analysis performed. Results In all, 33 of 54 patients with unilateral SCFE were enrolled into the study. In all, 29 (87.8%) had complete follow-up. Five of the enrolled patients (15.2%) developed a sequential slip requiring in situ pinning. Six of 33 (18.2%) patients had positive MRI findings: four of which proceeded to sequential SCFE and two which did not. One sequential slip had a negative MRI. PSA predicted 1/11 sequential slips (sensitivity 9.09%, specificity 81.4%, positive predictive value (PPV) 11.1%, negative predictive value (NPV) 77.8%) and mOBS predicted 5/11 sequential slips (sensitivity 45.5%, specificity 93%, PPV 62.5%, NPV 87%). An open triradiate cartilage was present in 8/11 patients with sequential slips (sensitivity 72.7%, specificity 81.4%, PPV 50%, NPV 92.1%). Conclusion MRI findings consistent with ‘pre-slip’ were present in 66.7% of patients who developed a sequential SCFE. Further study on the utility/sensitivity of MRI in predicting sequential SCFE is warranted. Level of Evidence II, diagnostic

Purpose To evaluate outcomes three years after treatment for slipped capital femoral epiphysis (SCFE): development of avascular necrosis (AVN), subsequent surgery, hip function and the contralateral hip. Methods This prospective cohort study included a total national population of 379 children treated for SCFE between 2007 and 2013. A total of 449 hips treated for SCFE and 151 hips treated with a prophylactic fixation were identified. The Barnhöft questionnaire, a valid patient-reported outcome measure (PROM), was used. Results In all, 90 hips had a severe slip, 61 of these were clinically unstable. AVN developed in 25 of the 449 hips. Six of 15 hips treated with capital realignment developed AVN. A peri-implant femur fracture occurred in three slipped hips and in two prophylactically pinned hips. In three of these five hips technical difficulties during surgery was identified. In 43 of 201 hips scheduled for regular follow-up a subsequent SCFE developed in the contralateral hip. Implant extraction after physeal closure was performed in 156 of 449 hips treated for SCFE and in 51 of 151 prophylactically fixed hips. Children with impaired hip function could be identified using the Barnhöft questionnaire. Conclusion Fixation in situ is justified to remain as the primary treatment of choice in SCFE. Overweight is more common in children with SCFE than in the average population. Prophylactic fixation is a safe procedure when performed using a correct technique. The number of patients who developed AVN after capital realignment is of concern. We recommend rigorous follow-up of both hips, including PROM evaluation, until physeal closure.

Published: August 2018

Plantar fasciopathy is very prevalent, affecting one in ten people in their lifetime. Around 90% of cases will resolve within 12 months with conservative treatment. Gastrocnemius tightness has been associated with dorsiflexion stiffness of the ankle and plantar fascia injury. The use of eccentric calf stretching with additional stretches for the fascia is possibly the non-operative treatment of choice for chronic plantar fasciopathy. Medial open release of approximately the medial third of the fascia and release of the first branch of the lateral plantar nerve has been the most accepted surgical treatment for years. Isolated proximal medial gastrocnemius release has been reported for refractory plantar fasciopathy with excellent results and none of the complications of plantar fasciotomy.

Published: August 2018

Abstract
Vibrational energy from intermodal transport system can be recovered through the application of piezoelectric energy harvesting system. The intermodal vibration sources are passenger cars and freight trucks moving on streets and highways, trains moving on railway tracks and planes moving on airport runways. However, the primary limiting factor of the application of the piezoelectric energy harvesting system has been the insignificant power output for power storage or to directly power electrical device. A special nano-mixture coating is developed to enhance the energy harvesting capability of the conventional piezoelectric material. This research investigates the impact of the nano-mixture coating on the power output. The experimental results of the nano-mixture coated system show substantial and explicit improvement on the power output. Alternative geometrical designs, trapezoidal and triangular are explored in anticipation for improved power output. But the rectangular energy harvester demonstrates better power harvesting capability. The results presented in this paper show the potential of the nano-mixture coating in power harvesting from intermodal transport system.
Humor and Performing Gender on TV Cooking Shows

Published: August 2018

AbstractA central aspect of humor is its social function in relating to others and in performing gender. Drawing on insights from interactional sociolinguistics and gender studies, this article explores the relationship between humor and gender in the context of one US instructional tv cooking showThe Pioneer Woman. The gender element, while essential to performed humor, is often neglected in research on humor, language, and the media; therefore, this paper looks into how humor is signaled in the cooking show individually and jointly. Humorous joking of the female host Ree Drummond is discussed, specifically self-directed humor and teasing as expressed in personal stories and exaggeration. The ambiguity of the humorous messages reveals contradictory messages: on the one hand, self-deprecating humor reveals feelings of inadequacy for not meeting gendered status quo, and on the other hand, teasing and self-deprecation function as a persuasive strategy to promote the celebrity’s cooking and brand.
Investigation of Cross-Phase Modulation-Induced Crosstalk with Sub-Planck Higher-Order Dispersion Parameters in Optical Transmission Systems
Authors: Bhatia Richa 
Published: August 2018

Abstract
Cross-phase modulation (XPM) is one of the major limiting effects in wavelength division multiplexed (WDM) optical transmission systems. This paper mathematically investigates the impact of XPM-induced crosstalk with second (2OD), third (3OD) and combination of sub-planck higher-order dispersion (HOD) parameters for WDM systems at different combinations of effective core areas, optical powers, modulating frequencies and dispersion values. It has been observed that XPM-induced crosstalk increases with increase in optical powers, modulating frequencies and dispersion values, but it reduces for higher effective core areas. The results for 2OD, 3OD and combination of dispersion parameters up to eighth order (8OD) have been reported. For instance, with a transmission length of 50 km for different values of optical power ranging from 0.1 mW to 2 mW, crosstalk due to XPM was observed to vary from (−75 to −44 dB), (−172 to −144 dB) and (−275 to −250 dB) in the presence of 2OD, 3OD and

Abstract
All optical majority gate is an optical logic structure with three input and one output ports. In this paper we designed an optical majority gate using a nonlinear resonant cavity based on photonic crystals. Plane wave expansion and finite difference time domain methods were used for calculating the band structure diagram and optical behavior of the optical majority gate, respectively. The proposed structure is ON, when two or three input ports are ON. The maximum time delay of our majority gate is about 5 ps.
On the Cost Minimization in Space Division Multiplexing Based Elastic Optical Networks
Authors: Iyer Sridhar 
Published: August 2018

Abstract
The required upgradation of the single-mode fibre (SMF)’s network capacity constrained by the non-linear Shannon’s limit, and the capacity provisioning which is needed by the future diverse Internet traffic can be resolved by the space division multiplexing (SDM) based elastic optical networks (EONs) (SDM-b-EONs). Recently, the multiple core fibre (MCF) technology has gained momentum over the current multi-fibre (MF) technology after laboratory experiments conducted on MCF models established much lower inter-core crosstalk values. In view of channel assignment, the spatial-super-channel (Spat-Sup-Chn) method has evolved as a prime candidate owing to its use of the joint switching (JoSw) mechanism which minimizes the cost. In the current work, in a JoSw based MCF enabled SDM-b-EON, for provisioning the demands; we aim at cost minimization while assigning both, the spectral and the spatial resources. Initially, we establish that in specific cases; use of the complete core allotment (CCA) technique, which uses all the MCF cores to provision the demands, leads to spectrum underutilization following which; we introduce a novel core adapting allotment (CAA) technique which adapts the cores amounts. We then investigate the possibility of using the CAA technique to provision the Spat-Sup-Chns simultaneously ensuring the same spectral requirements as needed when the CCA technique is used. For the performance evaluations, we consider the 37 core trench-assisted MCFs and our results show that by using the CAA technique, indeed there is a possibility of the transceivers amount being minimized in effect resulting in the Spat-Sup-Chn method being an economically practical solution.

Published: August 2018

Abstract

Background
Maternal diet and gestational age of infant may affect the composition of breast milk. The aim of this study was to evaluate the relationship between breast milk adiponectin and leptin levels of mothers delivering preterm and term infants and maternal diet.

Methods
Sixty-five mothers (31 preterm, 34 term) were included in the study. General information about parents and infants and food consumption of mothers were determined through a questionnaire. Milk samples were taken from mothers during the period between the 15th and 30th day after birth (mature milk). For the evaluation of maternal diet, the nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) were used.

Results
According to MAR, 71.0% of preterm mothers’ and 79.4% of term mothers’ dietary adequacy was categorized as “good”, and none of the mothers fell into the “insufficient” category (p>0.05). The median (interquartile range [IQR]) level of adipokines was found to be higher in preterm than in term mothers (24.6 [14.3] ng/mL; 22.9 [9.7] ng/mL for adiponectin and 2.0 [2.5] ng/mL; 0.0 [2.3] ng/mL for leptin, respectively) (p>0.05). A negative correlation was found between the leptin level and intake of unsaturated fatty acids, protein NAR and meat, poultry and fish consumption in preterm mothers (p<0.05). A positive correlation was found between leptin concentration and MAR, protein, calcium, potassium NAR and consumption of dairy products in term mothers (p<0.05). In the regression model, gestational age and MAR are important predictors of leptin.

Conclusions
These results show that maternal diet is related to the leptin content in breast milk.

Published: August 2018

Abstract

Background
Until the American Thyroid Association (ATA) guidelines on management of pediatric differentiated thyroid carcinoma (DTC) became available in 2015, all children with DTC were treated like adults. This study aims to investigate the outcome of pediatric DTC and factors predicting the response to therapy in pediatric DTC managed according to adult guidelines.

Methods
Clinical records of 41 children less than 18 years of age diagnosed with DTC followed from 2007 in a single center were reviewed. According to the new ATA classification for pediatric DTC, five had low-risk, 28 had intermediate-risk and eight had high-risk disease at presentation.

Results
There was no mortality or recurrence in this cohort of pediatric DTC patients and the cure rate was 46% during a mean follow-up of 44 months when they were managed according to adult guidelines. Neither the new ATA risk classification nor any clinicopathological character was identified which could predict the response to therapy. The new ATA guidelines would have avoided 27% of the radioiodine therapies given.

Conclusions
This study showed that DTC in children managed according to adult guidelines had a good cure rate. The new ATA guidelines on pediatric DTC might have drastically reduced the number of radioiodine therapies in the affected children. Long term prospective studies are needed to validate the benefits and risks of both these approaches.

Abstract

Objective
To investigate the quantitative and qualitative measures of the complex relationship between sexuality and the pregnant state.

Methods
An anonymous questionnaire [comprising the Female Sexual Function Index questionnaire, the Evaluation and Nurturing Relationship Issues, Communication and Happiness (ENRICH) Marital Satisfaction Scale, scale of attitudes toward sexuality, the World Health Organization (WHO) Well-Being Index and the scale of body image] was given to 243 women during antenatal classes.

Results
We evaluated 200 primiparous women, with an average age of 30.5 years (range 21–44), at an average gestational age of 31.6 weeks (range 19–38). We found that sexual intercourse during pregnancy is less frequent and less satisfying compared to the pre-pregnancy period. Sexuality or certain aspects of sexuality (arousal and satisfaction with sexuality) are associated with the fear of hurting the fetus, satisfaction with intimate partner relationship, general attitude toward sexuality, physical self-image and general well-being. Women who are more satisfied with their intimate partner relationship are also more satisfied with their sexuality.

Conclusion
Sexuality and sexual well-being during pregnancy are associated with the fear of hurting the fetus, satisfaction with intimate partner relationship, attitude toward sexuality, physical self-image and general well-being.

Published: August 2018

Abstract
The northern portion of the Atlantic Forest, namely Pernambuco Endemism Center (PEC), faces an extreme level of forest loss, with only 2% of its original forest remaining. In the PEC, mesocarnivores are the only remaining carnivores and, among them, the ocelot and South American coati present a poorly known or even ignored distribution. Our goal is to provide an overview of the current distribution and conservation status of both species in the PEC through camera trap survey, review of published scientific literature and a search for voucher specimens in mammal collections. Our data confirm the presence of the ocelot and the South America coati in the PEC. The ocelots were mainly recorded in fragments smaller than 12 km2, suggesting they might access the monoculture matrix and anthropogenic areas. The few recent records of coatis suggest a worse scenario, predicting an imminent local extinction. The PEC has witnessed a historical continued deforestation, which has reduced the remaining fragments and contributed to the accentuated decline of both species populations. Nevertheless, these Atlantic Forest remnants are paramount to supporting relict populations of mesocarnivores in the PEC, and their maintenance and connectivity should be a conservation priority.
Early and efficient detection of an endangered flying squirrel by arboreal camera trapping
Authors: Suzuki Kei K. , Ando Motokazu 
Published: August 2018

Abstract
Endangered species management is typically informed by an ecological knowledge of a species. Currently, little is known about the distribution and ecology of the Japanese flying squirrel (Pteromys momonga). To provide an effective rapid survey technique for flying squirrels, we used camera trap surveys and determined what methodology (i.e. camera placement, survey length) was most efficient. We placed 154 cameras in trees for 30 days. We detected flying squirrels at 12% of the camera points. The average suitable distance between camera and targeted tree (DCT) was 130 cm (SE: 15.4, range: 90–220). Moreover, flying squirrels were frequently detected on the trunks of taller trees. We found camera trap surveys were an efficient technique for detecting flying squirrels. Approximately 11% of camera points detected flying squirrels within one survey night. Initial detection of flying squirrels at a site occurred within 10 days at 58% of the points. To efficiently detect flying squirrels, we suggest that it is better to aim the camera towards taller trees at a suitable DCT and to conduct surveys for a minimum of 10 days at each site.

Abstract
This article reviews recent progress leading to the generation of optical vortex beams. After introducing the basics of optical vortex beams and their promising applications, we summarized different approaches for optical vortex generation by discrete components and laser cavities. We place particular emphasis on the recent development of vortex generation by the planar phase plates, which are able to engineer a spiral phasefront via dynamic or geometric phase in nanoscale, and highlight the independent operation of these two different phases which leads to a multifunctional optical vortex beam generation and independent spin-orbit interaction. We also introduced the recent progress on vortex lasing, including vortex beam generation from the output of bulk lasers by modification of conventional laser cavities with phase elements and from integrated on-chip microlasers. Similar approaches are also applied to generate fractional vortex beams carrying fractional topological charge. The advanced technology and approaches on design and nanofabrications enable multiple vortex beams generation from a single device via multiplexing, multicasting, and vortex array, open up opportunities for applications on data processing, information encoding/decoding, communication and parallel data processing, and micromanipulations.
