Authors: Brisighelli Giulia , Lorentz Liam , Pillay Tanyia , Westgarth-Taylor Christopher J. 
Published: May 2020

AbstractIn patients with anorectal malformations and a colostomy, the high-pressure distal colostogram is the technique of choice to determine the type of malformation and thus to plan the surgical repair. Perforations associated with high-pressure distal colostograms are very rare. The aim of our study was to identify pitfalls to prevent perforation secondary to high-pressure distal colostogram. The study included two male patients and was complicated with rectal perforations secondary to high-pressure distal colostogram. Both patients had an imperforate anus without a fistula. One patient had extraperitoneal rectal perforation with progressive contrast spillage into the peritoneum and demised. The other patient developed an extraperitoneal perforation and an associated necrotizing fasciitis of his perineum and scrotum, but he recovered well after debridement. Two further cases of rectal perforation have been described in the literature. Rectal perforation, although rare, is a described life-threatening complication secondary to high-pressure distal colostogram. The cause is excessive contrast pressure. Injection of contrast should be stopped once the distal end of the colon has a convex shape. Intraperitoneal perforation may cause hypovolemic/septic shock, and patients need to be appropriately resuscitated and should undergo laparotomy. Extraperitoneal perforation requires close monitoring for possible local complications, which may necessitate early debridement.
Idiopathic Intracranial Hypertension: Contemporary Management and Endovascular Techniques

AbstractIdiopathic intracranial hypertension (IIH) is a disease process of abnormally increased intracranial pressure in the absence of a mass lesion. Medical management, optic nerve fenestration, and surgical shunting procedures have failed to produce consistently successful results. In an unknown percentage of cases, IIH is caused by dural venous sinus obstruction which can be cured by endovascular treatment with dural venous sinus stent placement. This helps prevent progressive vision loss and worsening papilledema caused by underlying increased intracranial pressure from venous outflow obstruction. Patients are required to have an established diagnosis of IIH, preferably made by a neuroophthalmologist, with clearly documented papilledema or at minimum visual disturbance along with lumbar puncture opening pressure greater than 25 cm H2O. Transverse to sigmoid sinus focal narrowing (intraluminal filling defect or extrinsic compression) must be seen during the venous phase of neuroangiography (NA) along with a pressure gradient of 10 mm Hg or greater across the focal narrowing during dural venous sinus pressure monitoring. A successful reduction is defined as a pressure gradient of less than 10 mm Hg after stent placement. Neuroophthalmologic follow-up occurs within 1 to 2 months to assess for changes in papilledema. If papilledema is unchanged or worsened, NA and hemodynamic evaluation is repeated for consideration of restenting. Appropriate patient selection criteria are required for IIH venous sinus stenting. The utilization of refined endovascular techniques along with postprocedure follow-up protocols can ultimately cure IIH for a select group of patients.
Radial Access for Neurovascular Procedures
Authors: Satti Sudhakar R. , Vance Ansar Z. 
Published: May 2020

AbstractRadial access is increasingly being considered in neurovascular procedures after becoming the standard access route in percutaneous cardiovascular interventions. Current barriers include a lack of dedicated equipment for radial to neurovascular target vessels, lack of training for physicians and fellows, and physician bias toward femoral access secondary to greater experience and familiarity. Radial access has been proven to be safer and the preferred access route by most patients. These two factors make radial access inevitability when the aforementioned barriers are overcome. The purpose of this brief article is to highlight some important considerations of radial access specific to the neurovasculature.
Vertebral Compression Fractures: Evaluation and Management
Authors: Madassery Sreekumar 
Published: May 2020

AbstractPainful vertebral body compression fractures are prevalent in elderly patients. Two-thirds of patients will have spontaneous resolution of pain in 4 to 6 weeks and initial management is nonoperative with pain management and bracing. A focused history and exam can identify patients likely to benefit from vertebral body augmentation (e.g., vertebroplasty or kyphoplasty). Patients with persistent back pain and bone marrow edema on magnetic resonance imaging may benefit from injection of cement into the fractured vertebral body with either vertebroplasty or kyphoplasty. Patients most likely to benefit are those with severe pain refractory to nonoperative management who are offered intervention within 3 weeks. The procedure is usually performed as an outpatient with rare complications. Most patients report immediate, durable pain relief.

Published: May 2020

AbstractIschemia and no obstructive coronary arteries (INOCA) is a common clinical presentation, with a variety of causes that are often not fully investigated in routine clinical practice. The goal of our study was to characterize a real-world population of patients with INOCA, with a deeper focus on symptoms and stress test findings. The study population consisted of 435 patients who underwent diagnostic coronary angiography for anginal symptoms and/or evidence of myocardial ischemia at non-invasive imaging. In all patients angiography demonstrated nonobstructive coronary artery disease (CAD, less than 30% luminal diameter stenosis or fractional flow reserve > 0.8 and/or instantaneous wave-free ratio  > 0.89). Fifty-four percent of the patients were women. Atypical clinical presentation was more common in women (59.5 vs. 49.5%, p = 0.037). Women were more likely to have normal coronary arteries than men (41.8 vs. 16.2%, p < 0.001), and less likely than men to have hemodynamically non-significant CAD (32.1 vs. 55.1%, p < 0.001). No significant correlation between typicality of symptoms and evidence of ischemia was found in those patients (244/435, 56.1%) who had either dobutamine stress echocardiography or electrocardiogram stress test. INOCA is a common clinical condition, prevalent in women often presenting with atypical symptoms.

Published: May 2020

AbstractObjective The aim of this study was to evaluate the inter- and intra-observer reliability of plain digital radiographs for assessing normal feline femoral and tibial joint reference angles in the sagittal and frontal planes.Study Design This was a cadaveric radiographic anatomical study. that involved 20 short-haired domestic adult cats.Materials and Methods Sagittal and frontal plane tibial and femoral joint angles of 40 limbs were measured twice by three observers with different levels of experience. Inter- and intraobserver reliability was determined by the intra-class correlation coefficient (ICC). An ICC > 0.75 was considered high correlation, 0.74 > ICC > 0.60 good correlation, 0.59 > ICC > 0.4 fair correlation and an ICC < 0.40 poor correlation.Results Mean ± standard deviation angles were anatomic lateral proximal femoral angle (aLPFA) 110.6 ± 3.6; anatomic lateral distal femoral angle (aLDFA) 91.9 ± 2.1; mechanical lateral proximal femoral angle; mLPFA (mLPFA) 107.3 ± 3.6; mechanical lateral distal femoral angle (mLDFA) 95.5 ± 1.7; femoral neck anteversion (FNA) 121.9 ± 4.1; anatomical caudal proximal femoral angle (aCPFA) 156.1 ± 3.9; anatomical caudal distal femoral angle (aCDFA) 101.4 ± 1.4; mechanical medial proximal tibial angle (mMPTA) 93.5 ± 1.2; mechanical medial distal tibial angle (mMDTA) 100.5 ± 2.3; mechanical cranial proximal tibial angle (mCrPTA) 113.1 ± 3.2; tibial plateau angle (TPA) 23.1 ± 3.2; mechanical cranial proximal tibial angle (mCrDTA) 86.7 ± 3.1.The intra-observer ICC indicated high correlation for 70% or more of the measurements. The inter-observer agreement among observers was high. These results show that the radiographic method for measuring femoral and tibial joint angles was good or high, except for FNA and mCrDTA.Conclusions This study provides some radiographic anatomical and mechanical joint angles of the femurs and tibias of normal domestic short-haired cats. We found good reliability for both intra- and interobserver measurements.
Tissue Oximetry Readings Accurately Predict Late Complications in Patients Undergoing Free Flap Breast Reconstruction: Exploring the Optimal Cut Point Value
Authors: Saad Noah , Wang Howard , Karamanos Efstathios 
Published: May 2020

Abstract
Background The use of tissue oximetry for monitoring following free tissue transfer has become a common practice across the United States to facilitate early detection of poor flap perfusion in the postoperative setting. There is no consensus on the optimal value, below which there is a higher chance of wound complications in patients undergoing free flap breast reconstruction.
Methods Patients undergoing free flap breast reconstruction from 2015 to 2018 were retrospectively reviewed. Patients who returned to the operating room for a revision of the anastomosis were excluded from analysis. Patients were divided in two groups based on the development of late complications. Those were defined as fat necrosis, wound dehiscence, or distal flap ischemia/necrosis that developed after discharge from the hospital. Mean percutaneous oximetry readings of the first 24 hours were recorded and the mean change from the initial reading was calculated. The correlation between tissue oximetry change and development of complications was explored.
Results A total of 120 patients were identified. The mean age was 53, while the mean body mass index was 33. A total of 38 patients developed late wound complication. History of smoking, diabetes mellitus, neoadjuvant radiation therapy, and the mean change of the tissue oximetry reading were identified as independent predictors of wound complications. The absolute number of the tissue oximetry reading did not predict late complications. A multivariate analysis revealed that patients who experienced a mean decrease < 15% from the initial reading during the first 24 hours were significantly more likely to develop late flap-related wound complications.
Conclusion In patients undergoing free tissue breast reconstruction, tissue oximetry readings do not predict late wound complications. However, the mean change at 24 hours from the initial reading does. A decrease of <15% in tissue perfusion was associated with a significant increase in the probability of developing flap-related wound complications.

Published: May 2020

Abstract
Background Reliable perfusion of the distal portions of free flaps is decisive for the reconstructive success. Indocyanine green near-infrared video angiography (ICG-NIR-VA) has been adopted for objective assessment of free flap tissue perfusion but is thus far not used on a routine basis. Therefore, we investigated its intraoperative impact on decision-making and postoperative outcome.
Methods From January 2017 to June 2019, 88 consecutive adipo- or fasciocutaneus free flaps were performed in conjunction with intraoperative ICG-NIR-VA. Free flap tissue perfusion was first assessed clinically and then compared with ICG-NIR-VA findings. Based on the results, the decision for intraoperative trimming of critically perfused flap zones was made. The way of decision-making, flap success, and failure rates as well as intra- and postoperative complication rates were analyzed.
Results The overall free flap success rate was 92.0%. Partial flap necrosis occurred in five cases (5.7%) and total flap necrosis in two cases (2.3%). ICG-NIR-VA aided decision-making and flap design in 34 cases (38.6%) and led to complication-free postoperative courses. When ICG-NIR-VA was relied on (82 out of 88 flaps; 93.2%), there was no unpredicted postoperative tissue necrosis (overestimation). When ICG-NIR-VA was not relied on (6 out of 88 flaps; 6.8%), there were five cases of postoperative partial flap necrosis and one case of uneventful healing (underestimation). The sensitivity of ICG-NIR-VA was 100% (95% confidence interval [CI]: 64.6–100) and the specificity was 98.8% (95% CI: 93.3–100) with a positive predictive value of 87.5% (95% CI: 52.9–99.4) and a negative predictive value of 100% (95% CI: 95.4–100).
Conclusion Intraoperative ICG-NIR-VA objectified free flap perfusion and thus refined surgical decision-making on flap design in all cases. It could always predict tissue necrosis and subjectively improved outcomes in free flap surgery at our institution. Furthermore, it could be easily implemented in intraoperative routine, only adding minimal additional operative time.

Significance
Carotenoids are essential molecules in oxygenic photoautotrophs, and they fulfill essential requirements for human and animal nutrition. How carotenoid accumulation is regulated in the chloroplast, a cyanobacterium-derived organelle, remains poorly understood, despite significant advancements in identifying enzymes of the carotenoid biosynthetic pathway. This study identifies a role of chloroplast Sec14-like 1 (CPSFL1), a CRAL-TRIO protein of eukaryotic origin, in modulation of carotenoid biosynthesis and accumulation in the chloroplast. The CPSFL1 protein represents an isoprenoid- and carotenoid-binding protein that associates with membranes through interactions with the phospholipid phosphatidic acid. These findings have implications for understanding carotenoid biosynthesis and optimizing algal carotenoid nutritional quality.

Published: May 2020

Significance
DNA recombinases Dmc1 and Rad51 are both required during meiosis in most eukaryotes. Although they share high identity in amino acid sequence and biochemical properties, the mechanism of the requirement is unclear. The presynaptic filament formation is the first committed step in the process of homologous recombination. In this study, we combined the ensemble-based and the single-molecule experiments to dissect the assembly mechanism of Dmc1. Our results show that Dmc1 recombinases possess evolutionarily conserved nucleation preference that allows 5′-to-3′ filament formation. Moreover, Rad51 patches on single-stranded DNA stimulate the assembly of Dmc1, demonstrating the ability of Rad51 to facilitate the filament formation of Dmc1 in meiosis. The results provide a molecular rationale of why both recombinases are required in meiosis.

AbstractThis paper presents work-in-progress on the contextual variable tenor, here reconceptualised as ‘interactant relations’ in order to explore a radically different view of the relations of the interactants to the text in context. The functions of speaker/addressee are the starting point of an exploration of interactant relations because they represent the only features with the capacity to manage a text’s processes. This view implies that speaker/addressee have the capacity to internalise communal conventions, which places them at the centre of the language process. Implications of the results of the exploration for the classification of register are proposed. The paper’s methodology extends previous work on contextual networks (see especiallyHasan 2001a,2009b,2014,2016).i

Authors: Agrawal Prachi , Ganesh Talari 
Published: May 2020

Abstract
The selection criterion of a cricket team depends on so many factors like average, strike rate, consistency, economy rate, etc. For every factor, it may get a different team, but consistency plays an important role in the selection process. This paper outlines the selection process of players in the Indian Cricket Team for the ODI. A criterion is proposed for the evaluation of different factors on which the selection process can be done. This evaluation describes the consistent and inconsistent players and ranks of them. The players will be chosen at different categories like batsmen, bowler, all-rounder, and wicketkeeper. The evaluation mainly based on the consistency of the player. For this measure, integer optimization programming has been applied, and data has been taken from Jan 2015 to Sept 2017 of ODI matches.

Abstract
Generation of a sentence given an image, called image captioning, has been one of the most intriguing topics in computer vision. It incorporates knowledge of both image processing and natural language processing. Most of the current approaches integrates the concepts of neural network. Different predefined convolutional neural network (CNN) models are used for extracting features from an image and uni-directional or bi-directional recurrent neural network (RNN) for language modelling. This paper discusses about the commonly used models that are used as image encoder, such as Inception-V3, VGG19, VGG16 and InceptionResNetV2 while using the uni-directional LSTMs for the text generation. Further, the comparative analysis of the result has been obtained using the Bilingual Evaluation Understudy (BLEU) score on the Flickr8k dataset.

Published: May 2020

Abstract
This work investigates Automatic Generation Control in the one area thermal power system and optimization of gain parameters of conventional controller for non-reheat and reheat thermal power systems. Proportional – integral – derivative (PID) controller and PI controller is used for the comparison. The tuning of controller gain parameters is obtained by Integral Time Absolute Error (ITAE) approach for optimization. The proposed work utilizes new meta-heuristic algorithm for tuning of controller gain parameters. The GNA algorithm proved to be effective and robust for tuning a controller in the presence and absence of appropriate Generation Rate Constraint (GRC). The performance comparison and verification of simulation results is shown in time domain using Matlab. Finally, simulation result reveals that new GNA tuned PID controller provides more superior response in comparison to PI controller with and without including the effect of GRC.

Abstract
Energy preservation of the sensor become a prime objective of the routing protocols for prolong the period of sensor network and for efficient running of wireless sensor network applications. Taking this aspect into consideration, improved CBCCP approach has been developed that take energy, distance and node Density as parameter to choose cluster head (CH) and cluster-coordinator (CC). In Improved CBCCP, the network is partitioned into layers of fixed measurements and each cluster has one CH and varied no. of CC. Each CH and CC has the load of one cluster just to adjust the load. Data transmit to CH through normal nodes using single hop approach .Data transmitted to base station through cluster coordinator in type of chain. Communication distance is decreased by utilizing cluster coordinator for Intracluster communication and cluster head for inter-cluster communication. In comparison with CBCCP, Improved CBCCP balances the energy and prolongs the period of sensor network.

Published: May 2020

Abstract
Images hold a major influential power, as evidence or as a medium to convey messages. An image is worth a thousand words and is used extensively in this era for digital communications. Hence, their tampering can cause major losses, which is why their manipulations techniques have grown sophisticated over time. Copy-move forgery is a technique, wherein an area of an image is replicated to another area of the image. The paper reviews state of the art copy-move forgery detection (CMFD)methods listing the approach and limitations of various techniques with the help of a table for better readability.
