Is There a Risk of Saddle Nose Deformity after Spreader Grafts and Flaps?
Authors: Eweiss Ahmed 
Published: February 2022

AbstractSpreader grafts have been used successfully for years to augment the nasal valves among other indications. Spreader flaps have been described as an alternative. However, the literature discussing the complications of these procedures is scarce. This study aims to report and discuss the improvements and complications resulting from using spreader grafts or flaps in a cohort of patients operated upon by the author. Particular stress is given to a group of patients who developed saddle nose deformity after surgery. This cohort included 80 cases of rhinoplasty involving the use of spreader grafts or/and flaps. There was a highly significant improvement in nasal functions postoperatively. Postoperative saddle nose deformity was observed in five patients (6.25%). Spreader grafts/flaps are highly effective in improving nasal functions, but saddle nose deformity appears to be a possible risk. This complication has not been previously reported in the literature in relation to these procedures.

Abstract
Introduction Ki-67 is often used as a proliferation index to evaluate how aggressive a tumor is and its likelihood of recurrence. Vestibular schwannomas (VS) are a unique benign pathology that lends itself well to evaluation with Ki-67 as a potential marker for disease recurrence or progression following surgical resection.
Methods All English language studies of VSs and Ki-67 indices were screened. Studies were considered eligible for inclusion if they reported series of VSs undergoing primary resection without prior irradiation, with outcomes including both recurrence/progression and Ki-67 for individual patients. For published studies reporting pooled Ki-67 index data without detailed by-patient values, we contacted the authors to request data sharing for the current meta-analysis. Studies reporting a relationship between Ki-67 index and clinical outcomes in VS for which detailed patients' outcomes or Ki-67 indices could not be obtained were incorporated into the descriptive analysis, but excluded from the formal (i.e., quantitative) meta-analysis.
Results A systematic review identified 104 candidate citations of which 12 met inclusion criteria. Six of these studies had accessible patient-specific data. Individual patient data were collected from these studies for calculation of discrete study effect sizes, pooling via random-effects modeling with restricted maximum likelihood, and meta-analysis. The standardized mean difference in Ki-67 indices between those with and without recurrence was calculated as 0.79% (95% confidence interval [CI]: 0.28–1.30; p = 0.0026).
Conclusion Ki-67 index may be higher in VSs that demonstrate recurrence/progression following surgical resection. This may represent a promising means of evaluating tumor recurrence and potential need for early adjuvant therapy for VSs.
Laparoscopy-Assisted Transgastric ERCP: A Challenging Technique for Biliary Clearance Post Roux-en-Y Gastric Bypass

Published: February 2022

AbstractBiliary complications after Roux-en-Y gastric bypass (RYGB) are not uncommon. Managing choledocholithiasis in this subset of patients is challenging as conventional endoscopic retrograde cholangiopancreatography (ERCP) is not possible due to lack of peroral access to the second part of duodenum. Enteroscopic approach, however, theoretically feasible is difficult and cumbersome, often resulting in failed procedure. Small series has reported higher success with a novel technique of laparoscopic transgastric access for ERCP. Laparoscopy-assisted ERCP (LA-ERCP) is now increasingly being recognized as a safe and reliable technique for biliary clearance with a low complication rate, making it a preferred approach for managing biliopancreatic disease in these groups of patients. Here we report a case of a young patient with gallstone disease and choledocholithiasis presenting with obstructive jaundice post RYGB who was successfully managed by LA-ERCP followed by laparoscopic cholecystectomy in the same session.

Published: February 2022

AbstractWeb-based health information plays an increasingly vital role in spreading health information. Many patients interested in aesthetic surgery study the procedure on the Internet. This study aims to evaluate the quality of online health information on injectable fillers using the modified “Ensuring Quality Information for Patients” (EQIP) tool. Nine different search terms, including “fillers,” “fuller cheeks,” “wrinkle removal,” and “antiwrinkle treatment” were identified and queried on Google. Unique links from the first three pages of each search term were identified and evaluated if the contents were in English language and were for general non-medical public use. A total of 172 websites were analyzed, with a median EQIP score of 20. In total 129 websites belonged to aesthetic practitioners, of which 81 were operated by medical doctors. Eighty-three percent of websites disclosed some forms of postoperative complications, most commonly edema (74%) and bruising (73%). Blindness and tissue necrosis were only mentioned by 12 and 10% of the websites, respectively. The current health information available on injectable fillers is of poor quality. While many do provide some information on risks, the majority of websites fail to disclose severe complications and quantifying risks. This poses a barrier against informed decision-making and may lead to unrealistic expectations. Patient satisfaction and expectations may be improved by developing better online education resources on fillers.

Published: February 2022

AbstractInjections with hyaluronic acid (HA) fillers for facial rejuvenation and soft-tissue augmentation are among the most popular aesthetic procedures worldwide. Many HA fillers are available with unique manufacturing processes and distinct in vitro physicochemical and rheologic properties, which result in important differences in the fillers' clinical performance. The aim of this paper is to provide an overview of the properties most widely used to characterize HA fillers and to report their rheologic and physicochemical values obtained using standardized methodology to allow scientifically based comparisons. Understanding rheologic and physicochemical properties will guide clinicians in aligning HA characteristics to the facial area being treated for optimal clinical performance.
Neuropsychiatric Treatments for Parkinson's Disease: Nonpharmacological Approaches
Authors: Mathur Neha , Bhatt Haseel , Lidstone Sarah C. 
Published: February 2022

AbstractAlthough diagnosed by characteristic motor features, Parkinson's disease and other movement disorders are frequently accompanied by a wide range of neuropsychiatric symptoms that require a multidisciplinary approach for treatment. Neuropsychiatric symptoms such as depression, anxiety and cognitive symptoms strongly influence quality of life, motor symptoms, and non-motor bodily symptoms. This review summarizes our current understanding of the neuropsychiatric symptoms in movement disorders and discusses the evidence base for treatments focusing on rehabilitation and nonpharmacological approaches. A practical approach is then proposed for patient selection for specific treatments based on disease stage. The article focuses mostly on Parkinson's disease as a prototypical movement disorder with the largest evidence base but the principles discussed herein are applicable to a range of other movement disorders.
Under-represented, cautious, and modest: the gender gap at European Union Politics
Authors: Bettecken Julia , Klöckner Ann-Cathrin , Kurch Charlotte , Schneider Gerald 
Published: February 2022

AbstractThe gender gap pervades many core aspects of political science. This article reports that females continue to be under-represented as authors and reviewers in European Union Politics and that these differences have only diminished slightly since the second half of the 2000s. We also report that females use more cautious and modest language in their correspondence with the editorial office, but do not find evidence that this under-studied aspect of the gender gap affects the outcome of the reviewing process. The authors discuss some measures European Union Politics and other journals might take to address the imbalance.
The Social Practice of Care Hotel Vacations
Authors: Bargeman Bertine , Richards Greg , Charante-Stoffelen Marleen 
Published: February 2022

Abstract

Due to the increase in the number of elderly and people seeking medical care, the hotel market with a blend of care and leisure experiences is expected to grow in the future (
Han, 2013
;
Karuppan & Karuppan, 2010
;
Laesser, 2011
). The role of care hotels as an intersection between the care and the tourism sectors makes a vacation in a care hotel an interesting social practice to study. In this contribution a social practices approach (
Spaargaren, 1997
) is applied to investigate how demand and supply interact during a care hotel vacation. Semi-structured interviews are used to identify successful and less successful interactions or practices between senior guests and personnel in five Dutch care hotels. These interactions are related to materials (care and leisure facilities), competences (skills and empathy of the personnel) and meanings (motivations and aspirations of guests) in the care hotel practice (see
Shove et al., 2012
). The results show that a social practice approach combined with a qualitative research method may be more suited to analysing the complex encounters between guests and personnel during care hotel vacations than more traditional theories from service or experience quality studies. Simultaneously, this study makes clear that we need to develop alternative qualitative (and/or quantitative) research methods to study more privacy-related or intimate practices or rituals as in the case of care hotels.

Homology conditions for RT surfaces in double holography
Authors: Neuenfeld Dominik 
Published: February 2022

Abstract
Recently, a novel formula for computing entropy in theories coupled to semi-classical gravity has been devised. Using this so-called island formula the entropy of semi-classical black holes follows a Page curve. Here, we study the relation between this novel entropy and semi-classical entropy in the context of doubly-holographic models. Double holography allows for two different d-dimensional descriptions of a black hole coupled to a non-gravitational bath, both of which allow a holographic computation of von Neumann entropy in bath subregions. We argue that the correct homology constraint for Ryu–Takayanagi surfaces depends on which of those d-dimensional perspectives is taken. As a consequence the von Neumann entropies of a fixed subregion in both descriptions can disagree. We discuss how the von Neumann entropies in both descriptions are related to the entropy computed by the island formula and coarse grained entropy. Moreover, we argue that the way operators transform between the two descriptions depends on their complexity. A simple toy model is introduced to demonstrate that a sufficiently complicated map between two descriptions of the system can give rise to an island formula and wormholes. Lastly, we speculate about the relation between double-holography and black hole complementarity.
The representation of women in Irish Leaving Certificate Physics textbooks
Authors: Pillion Karen , Bergin Shane D 
Published: February 2022

Abstract
This paper examines the representation of women in Irish Leaving Certificate Physics textbooks. Findings show that women are significantly underrepresented, both in terms of scientific characters (historic and current) described within the textbooks, and also in terms of more general non-scientific characters within the books. Furthermore, analysis suggests that the language used to describe characters mentioned in the books may compound gender inequalities. Relevant policies (curricular, governmental, etc) are examined and suggestions are made to improve gender balance in future textbooks.
Simple physics behind the flight of a drone
Authors: Monteiro Martín , Stari Cecilia , Cabeza Cecilia , Martí Arturo C 
Published: February 2022

Abstract
The flight of a quadcopter drone, readily available as a toy, is analyzed using simple physics concepts. A smartphone with built-in accelerometer and gyroscope was attached to the drone to register the accelerations and angular velocities along the three spatial axis while the drone is taking off, landing or rotating. The vertical speed, the height and one of the angular coordinates are obtained through numerical integration of the acceleration values and compared with information provided by the manufacturer. The analysis of these quantities provides an opportunity to gain insight into important physics concepts involving Newton laws and conservation principles in a stimulating environment.

AbstractObjective. The assessment of lung mechanics in horses is nowadays based on invasive methods that may require sedation. The forced oscillation technique (FOT) allows the non-invasive assessment of respiratory mechanics during spontaneous breathing, but current devices are complex, cumbersome, expensive, and difficult to be applied in horses.Approach. We developed a portable FOT device based on a novel approach in which the pressure waveforms are generated by a servo-controlled ducted fan. This new approach allows the design of devices that are more sturdy, compact, and portable compared to already existing approaches. The prototype includes 1) a small microcontroller-based electronic board for controlling the fan and measuring flow and pressure and 2) an optimized data processing algorithm.Main results. This device provides a maximum error of 0.06 cmH2O·s/L and 0.15 cmH2O·s/L in measuring respiratory resistance and reactance duringin-vitrovalidation. A pilot study was also performed on three healthy horses and three horses with severe equine asthma (SEA) and it demonstrated good tolerability and feasibility of the new device. Total respiratory system resistance (Rrs) and reactance (Xrs) significantly differed (p< 0.05) between groups. At 5 Hz,Rrswas 0.66 ± 0.02 cmH2O·s/L and 0.94 ± 0.07 cmH2O·s/L in healthy and in SEA, respectively.Xrs0.38 ± 0.02 cmH2O·s/L and −0.27 ± 0.05 cmH2O·s/L.Significance. This novel approach for applying FOT allowed the development of a small, affordable, and portable device for the non-invasive evaluation of respiratory mechanics in spontaneously breathing horses, providing a useful new tool for improving veterinary respiratory medicine. Moreover, our results provide supporting evidence of the value of this novel approach for developing portable FOT devices also for applications in humans.
Vortex shaking study with use of linear voltage–current law
Authors: Fazilleau Philippe , Dilasser Guillaume 
Published: February 2022

Abstract
Experiments show that the application of an AC magnetic field parallel to a thin superconductor tape can reduce the magnetization caused by screening currents. A theory has been developed by Sakamoto and Brandt stating that a DC electric field is generated during the application of the AC magnetic field and leads to the decay of the screening currents through the homogenization of the current density within the tape. The DC electrical field has the same direction as the current lines and is linear with the current density magnitude. First, we perform numerical simulations via a finite difference method in MATLAB to compute the effects of such a DC electrical field and its linear law and compare it with the widely used power law on two different cases an infinitely long thin tape and a single tape solenoid. We then study the effects of vortex-shaking computed with both laws on a coil made of several turns.

Published: February 2022

Abstract
A wind and react (W&R) coil of inner diameter 53 mm has been made from multi-core MgB2/Nb/CuNi wire manufactured by the internal magnesium diffusion (IMD) process. The W&R coil is wound from non-insulated rectangular wire of 1 mm2 with only 5 µm thick stainless steel foil used for interlayer insulation. The transport current performance of the coil and short wire samples was measured in a liquid He bath at external magnetic fields of 4.5–8.5 T and also in self-field conditions in sub-cooled water ice at temperatures between 33 K and 38 K. The presented MgB2 coil exhibits stable behavior at water ice cooling, and its high space factor allows a high current density of winding in comparison to the data from the already published MgB2 coils. The presented results demonstrate that MgB2 windings can be used safely in He-free conditions inside sub-cooled water ice, and this technique can be further optimized and used for future MgB2 coils.
Photon BEC with thermo-optic interaction at dimensional crossover
Authors: Stein Enrico , Pelster Axel 
Published: February 2022

Abstract
Since the advent of experiments with photon Bose–Einstein condensates (phBECs) in dye-filled microcavities in 2010, many investigations have focussed upon the emerging effective photon–photon interaction. Despite its smallness, it can be identified to stem from two physically distinct mechanisms. On the one hand, a Kerr nonlinearity of the dye medium yields a photon–photon contact interaction. On the other hand, a heating of the dye medium leads to an additional thermo-optic interaction, which is both delayed and non-local. The latter turns out to represent the leading contribution to the effective interaction for the current 2D experiments. Here we analyse theoretically how the effective photon–photon interaction increases when the system dimension is reduced from 2D to 1D. To this end, we consider an anisotropic harmonic trapping potential and determine via a variational approach how the properties of the phBEC in general, and both aforementioned interaction mechanisms in particular, change with increasing anisotropy. We find that the thermo-optic interaction strength increases at first linearly with the trap aspect ratio and later on saturates at a certain value of the trap aspect ratio. Furthermore, in the strong 1D limit the roles of both interactions get reversed as the thermo-optic interaction remains saturated and the contact Kerr interaction becomes the leading interaction mechanism. Finally, we discuss how the predicted effects can be measured experimentally.
Search for cosmological time dilation from gamma-ray bursts — a 2021 status update
Authors: Singh Amitesh , Desai Shantanu 
Published: February 2022

Abstract
We carry out a search for signatures of cosmological time dilation in the light curves of Gamma Ray Bursts (GRBs), detected by the Neil Gehrels Swift Observatory. For this purpose, we calculate two different durations (T
50 and T
90) for a sample of 247 GRBs in the fixed rest frame energy interval of 140–350 keV, similar to a previous work [1]. We then carry out a power law-based regression analysis between the durations and redshifts. This search is done using both the unbinned as well as the binned data, where both the weighted mean and the geometric mean was used.
For each analysis, we also calculate the intrinsic scatter to determine the tightness of the relation. We find that the weighted mean-based binned data for long GRBs and the geometric mean-based binned data is consistent with the cosmological time dilation signature, whereas the analyses using unbinned durations show a very large scatter. We also make our analysis codes and the procedure for obtaining the light curves and estimation of T

Characterizing spatio-temporal aspects of chirped pulse amplification laser micro-cone target interaction
Authors: Ionel Laura 
Published: February 2022

Abstract
A numerical study of spatio-temporal distortions effect on the output chirped pulse amplification (CPA) laser beam at the interaction with a micro-cone target was developed. For this, several laser configurations based on CPA technique have been designed and complex study for spatio-temporal distortions compensation has been elaborated using a raytracing model from Optica module of Mathematica in order to determine the optimum conditions to streamline the laser field intensification in the vicinity of laser–conical target interaction point. This numerical model offers an effective solution to fine tune the output CPA beam pulse duration or to control or mitigate the current beam pointing fluctuations caused by specific internal processes during experiments in high-power regimes.
Bio-based resin/cellulose composites for UV-assisted 3D printed orthopedic casts

Published: February 2022

Abstract
An orthopedic cast is a device used for stabilizing bone fracture. To date, the conventional plaster casts do not have reasonable control over the functional characteristics of comfort, lightweight, and return in patients’ everyday life during the healing process. Three-dimensional (3D) printing is a rapidly growing and impressive technology with plentiful possibilities for customized rehabilitation tools, particularly the orthopedic cast. However, the 3D-printing materials are still limited, especially in terms of their printability and mechanical strength. In this work, bio-based resin/cellulose composites are developed as alternative materials to enhance mechanical performance for DLP (Digital Light Processing) 3D printing, which could further potentially fabricate 3D-printed cast. Triacetin, polypropylene glycol (PPG) and PEGDA are used to improve the distribution and dispersion of cellulose in bio-based resin. The results indicated that the mechanical properties improved with appropriate printed direction. The 90° printing direction gave the higher flexural strength than that of the 46.62° printing direction, which are 2650 MPa and 2487 MPa, respectively. Also, more printing accuracy was found for the 90° printing direction. SEM images revealed well dispersion of cellulose in bio-based PLA resin composite with PEGDA. However, the interfacial adhesion needs to be further improved to enhance the mechanical performance.
