Authors: Ivanov Afanasiy , Vaschenko Semen
Published: November 2020

The article presents a new method of channel angular pressing (CAP) of annular metal billets developed on the basis of the invention patented in the Russian Federation. The diagram, general view and details of the device produced on the basis of the invention are presented. An example of cold CAP of an annular billet from technical copper M4 is given. Annular billets from copper M4 with 13.9 mm outer diameter, 1.9 mm wall thickness and 4.1 mm height were subjected to CAP at room temperature with a device with the outlet and inlet channels diameters ratio D / d ≅ 1.14. The annular billet was loaded with a tubular punch by a hydraulic press. The diagram of the loading of an annular billet from copper M4 is presented. The CAP resulted in the hardening of the billet material. The results on the mechanical properties under axial compression of annular samples from commercial copper M4 in the initial state and after CAP are presented. Mechanical tests for axial compression of annular samples with 16 mm outer diameter, 1.45 mm wall thickness and 3.35 mm height were carried out with Instron-1195 testing machine at a constant loading rate of ≈ 0.83*10-5 ms-1. An increase in strength of copper M4 as a result of CAP at room temperature was found.

Enterocytozoon bieneusi is an intestinal pathogen that infects a wide range of species, including humans. Cattle constitute an important host for E. bieneusi; however, there is a scarcity of information on the prevalence and genotyping of E. bieneusi in cattle in the Hainan Province of China. In this study, PCR analysis of 314 fecal samples from cattle in six cities of Hainan was performed for genotype identification. The average prevalence of E. bieneusi in these animals was 9.9% (31/314), and ranged from 0.0% (0/12) to 20.5% (8/39). Five known genotypes – EbpC (n = 14), BEB4 (n = 12), J (n = 2), I (n = 1), and CHG5 (n = 1) – and a novel genotype: HNC-I (n = 1) – were identified. Genotypes EbpC and HNC-I were placed in zoonotic Group 1, and the remaining four genotypes (BEB4, J, I, and CHG5) were placed in Group 2. Since 93.5% of the genotypes found in the cattle (29/31) (EbpC, BEB4, J, and I) have previously been found in humans, these genotypes are probably involved in the transmission of microsporidiosis to humans.

Published: November 2020

Introduction Nonunion of the distal radius is an extremely rare and serious complication with unpredictable outcomes. The aim of the present study is to analyze the radiological and functional results after a protocolized surgical treatment.

Material and Methods A retrospective review of case series of patients with diagnosis of nonunion of the distal radius surgically treated from 2010 to 2016. The diagnosis of nonunion was made at 6 months without signs of consolidation. According to computed tomography (CT) scan images, we propose a classification of this complication as type I: no deformity or mild deformity, with subchondral metaphyseal bone stock beneath lunate facet greater than 10 mm, with no degenerative changes at the distal radioulnar joint (DRUJ); type II: moderate deformity or degenerative changes in the DRUJ, distinguishing between IIA and IIB based on the subchondral metaphyseal bone stock; and type III: degenerative changes at the midcarpal joint. In all cases, a reconstructive technique consisting of volar locking plate osteosynthesis with autologous tailored iliac crest graft was performed, hence none of the cases were classified as type III.

Results In total, six cases were included. Mean follow-up: 58 months (range: 30–108 months). Consolidation was achieved in a mean period of 5 months (range: 3–9 months). Average active range of motion: flexion: 54° (range: 10°–80°); extension: 40° (range: 10°–85°); supination: 82.5° (range: 75°–85°); pronation 80° (range: 55–85°); radial deviation: 15° (range: 5°–20°); and ulnar deviation 15° (range: 5–20°). Mean strength: 24.15 Kg (6.9–35 Kg). The average score on the Visual Analog Scale (VAS) at rest was of 0.6 (0–2), and with movement, it was of 1.8 (0–4). The mean postoperative score on the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was of 18.48 (range: 0–50.8). Average radial height: 9.65 mm (range: 7–12 mm); average radial angulation: 17° (10°–20°); volar tilt: 8.36° (range: 0.2°–21°); average ulnar variance: 1.52 mm (range: 0–3.5 mm). Complications: persistent nonunion, superficial wound infection, acquired residual ulnar club hand deformity, radiocarpal arthritis, and midcarpal arthritis. Nevertheless, no salvage techniques were needed or requested during the follow-up, with all patients in an active work situation or living an active life in complete normality.

Conclusions The protocolized surgical treatment of pseudoarthrosis of the the distal radius, based on our proposed classification, offers good functional outcomes in the long-term follow-up.

Published: November 2020

Objective Pelvic floor dysfunction (PFD) is a major health care problem predominately affecting the elderly female. It impairs quality of life and patients increasingly expect a solution. Barium defaecating proctography (BDP) is frequently used in the assessment of patients with PFD. The aim of this study was to present our findings from BDP and to look at the proportion of patients who went on to have surgery following their investigations.

Methods All patients who underwent BDP in a tertiary referral center were identified retrospectively from the computerized radiology information system. Demographic data and radiologic findings were extracted. Data regarding those who had surgery were retrieved from the anonymized patient registry.

Results A total of 671 patients had a BDP during the study period. The main symptoms investigated were obstructed defecation or chronic constipation (64%). Complete barium evacuation was observed in 70% of the patients, while 17% were noted to have incomplete and 13% no evacuation. A large rectocele (>5 cm) was noted in 38% while nearly 5% had frank prolapse. There was no significant association between a rectocele and any of the presenting symptoms. Seventy-eight (12%) patients went on to have operation, of which 17 (22%) had multiple procedures. Three patients ended up with a permanent stoma.

Conclusion BDP contributes to decision making in patients with PFD. However, results need to be interpreted with caution and in conjunction with other tests and clinical examination to maintain a low rate of operation and reduce the risk of adverse outcomes for these patients.

Published: November 2020

Background Endometriosis (EM) is an estrogen-dependent disease characterized by the presence of endometrial gland and stroma outside the uterus. It is commonly seen in the reproductive age group and is a leading cause of infertility. Patients present with chronic pelvic pain, menstrual abnormalities, dyspareunia, or mass per abdomen. Surgical excision is the treatment of choice with postoperative medications and progesterone agents.

Aims and Objectives This study aims at determining the distribution of EM in terms of age, parity, symptoms, site, morphological features. We also analyzed the management of EM in these cases.

Methodology This is a retrospective study done in a tertiary care hospital in Mangalore, India. The case records of 77 histopathologically confirmed cases of EM during the 7 years between June 2012 and May 2019 were studied. Demographic profiles, parity, presenting complaints, site of the lesion, morphological features, treatment given, follow-up, and recurrence were noted and analyzed.

Results Of the 77 patients with EM, the most common age group was the fourth decade (40%). The majority (31, 40.25%) of the patients in this study were nulliparous. Chronic pelvic pain was the most common symptom. The most frequent site was ovary.

Conclusion The most frequent site of EM is ovary, leading to infertility. With the advent of laparoscopy, early diagnosis and excision have been feasible. The histopathological examination should be done for confirmation. Awareness of this disease among health care professionals is necessary whenever a woman in reproductive age presents with chronic pelvic pain and infertility.
Safety and Efficacy of Apixaban For Therapeutic Anticoagulation in Critically Ill ICU Patients with Severe COVID-19 Respiratory Disease
Authors: Wenzler Eric , Engineer Monaz H. , Yaqoob Maidah , Benken Scott T.
Published: November 2020

Introduction Despite the use of unfractionated heparin (UFH) or low molecular weight heparin (LMWH), rates of thromboembolic disease, and subsequent morbidity and mortality remain unacceptably high in patients with severe novel coronavirus disease 2019 (COVID-19) disease. Direct oral anticoagulants (DOACs), such as apixaban, have numerous purported benefits although the safety and efficacy of their use in intensive care unit (ICU) patients with severe COVID-19 has yet to be evaluated.

Materials and Methods Single-center, retrospective cohort study of 21 ICU patients with severe COVID-19 respiratory disease treated with apixaban for atrial fibrillation (AFib), venous thromboembolism (VTE), catheter-induced thrombosis, and/or COVID-19-induced coagulopathy. The primary objective was to evaluate the incidence of bleeding events and secondary objectives included thromboembolic events, coagulation parameters, and mortality.

Results Ninety percent of patients were non-White, 43% were obese, 90% had acute respiratory distress syndrome, and 76% required mechanical ventilation. Nearly half of (47.6%) also experienced renal dysfunction and required renal replacement therapy. Eighty-six percent of patients received prophylaxis or treatment with UFH or LMWH within the 24-hour period prior to apixaban initiation. Patients were initiated on apixaban for the treatment of suspected or confirmed VTE (67%) or AFib (33%). All coagulation parameters remained abnormal but stable throughout the 10-day monitoring period. No patients experienced any major bleeding events or thrombosis throughout the study period. There were four deaths during the follow-up period, all deemed unrelated to coagulopathy or bleeding.

Conclusion Apixaban appeared safe and efficacious in ICU patients with severe COVID-19 disease. These data encourage future trials seeking to optimize anticoagulation strategies in patients with severe COVID-19.

Nature and outcomes of sanctioned medical misconduct in six international jurisdictions: a case series
Authors: Grant Nicole , Valentine Safire , Majer James , Taylor David McD.
Published: November 2020

Objective The aim of this study was to determine the types of medical misconduct, the practitioner, specialities and jurisdictions at risk, patient outcomes and the sanctions imposed. Methods This study was a retrospective case series of 822 adverse medical tribunal determinations in Australia, New Zealand, Canada (Ontario, Alberta), Pennsylvania (USA), Singapore and Hong Kong in 2013–17. Results Inappropriate medical care and illegal or unethical prescribing were the most common types of misconduct. Misconduct varied with practitioner sex, international medical graduate status, speciality and jurisdiction (P < 0.05). Cases of inappropriate medical care were more common in Singapore (46.7% of all Singapore cases; 95% confidence interval (CI) 31.9–62.0) and among surgeons (47.6% of all surgeon cases; 95% CI 36.5–58.8). Illegal or unethical prescribing was more common in Australia (31.1%; 95% CI 24.8–38.2) and among general or family practitioners (26.9%; 95% CI 20.0–35.0). Misconduct not related to patients was more common in Pennsylvania (30.3%; 95% CI 25.2–36.0) and among local graduates (20.5%; 95% CI 17.1–24.5). Sexual misconduct was more common in Australia (29.6%; 95% CI 23.4–36.6) and among males (19.6%, 95% CI 16.7–22.8). Healthcare dishonesty was more common in Hong Kong (21.8%; 95% CI 14.0–32.2) and among surgeons (13.4%; 95% CI 7.2–23.2). The most common patient outcomes were patient risk (40.6%; 95% CI 36.1–45.4) and death and actual physical harm combined (31.2%; 95% CI 26.9–35.7). Sanctions were most commonly suspension or deregistration. Deregistration was most common in cases of sexual misconduct. Conclusion Medical misconduct varies widely. Risk factors for particular misconduct types are apparent among jurisdictions and practitioner characteristics. The nature of patient harm varied by type of misconduct, with illegal unethical prescribing commonly leading to drug dependency and sexual misconduct leading to psychiatric injury. What is known about the topic? Medical misconduct is a continuing problem. Tribunals and medical boards sanction misconduct to protect patient safety and public trust. What does this paper add? Tribunals and boards differ in misconduct reporting and permitting public access to determinations. Types of misconduct vary between international jurisdictions, practitioner sex, international graduate status and speciality. Risk and physical injury (including death) are the most common patient outcomes. The nature of patient harm varied by type of misconduct, with illegal unethical prescribing commonly leading to drug dependency and sexual misconduct leading to psychiatric injury. What are the implications for practitioners? Medical colleges should tailor trainee programs to address the common types of misconduct within their specialities. Standardisation of misconduct reporting, and report access, across jurisdictions would facilitate ongoing surveillance and intervention evaluation.
Yield measurement is valuable for pricing beef carcasses
Authors: Pitchford W. S. , Trotta C. M. , Hebart M. L. , Miller S. M. , Rutley D. L.
Published: November 2020

Context
The most common way of pricing beef carcasses is through a price grid. Most processors make greater profit from higher-quality carcasses, which are those with higher meat yield and eating quality.

Aims
The aim of this study was to calculate the value of diverse carcasses and compare pricing mechanisms on their ability to discriminate variation in meat yield and predicted eating quality.

Methods
Hereford cross steer carcasses (153) were boned out to record saleable meat and yield. Six methods were used to calculate carcass price (AU$/kg). All were adjusted to the same average carcass value to allow comparisons, assuming that the overall payment does not change, but comparing the effect of having greater premiums and discounts. The six prices were based on a commercial grid, grid plus eating quality premium, yield of saleable meat only (constant price for all saleable meat), yield with eating quality premium, then the yield prices with optimum (quadratic) weight and fatness penalties based on grid optimums.

Key results
Measurements of meat quality (eye muscle area and marble score) or saleable meat yield accounted for no variation in the grid price. However, measurement of yield accounted for substantial variation in prices calculated from yield and eating quality.

Conclusions
The current grids do not encourage high-quality meat production and, assuming that yield and eating quality are important to processors, an actual measurement of yield is crucial to guide processing decisions (e.g. cutting plans) to maximise carcass value and feed market signals back to beef producers.

Implications
Improved measurement of meat yield is required if carcass prices are to reflect carcass quality or the potential value captured.
Cellular pathways of calcium transport and concentration toward mineral formation in sea urchin larvae
Authors: Kahil Keren , Varsano Neta , Sorrentino Andrea , Pereiro Eva , Rez Peter , Weiner Steve , Addadi Lia
Published: November 2020

Significance

Organisms form mineralized skeletons, many of which are composed of calcium salts. Marine organisms extract calcium ions from sea water. One of the main unresolved issues is how organisms concentrate calcium by more than three orders of magnitude to achieve mineral deposition in their skeleton. Here we determine the calcium state in each of the calcium-containing vesicles inside the spicule-building cells of sea urchin larvae. We show that within one cell there is a wide range of concentrations and states from solution to solid. We hypothesize that calcium concentration increases gradually in each vesicle, starting from seawater levels and until mineral is deposited. This model might well be relevant to other phyla, thus advancing the understanding of biomineralization processes.
Race and ethnic variation in college students’ allostatic regulation of racism-related stress

Published: November 2020

Significance

Racial resentment, antiimmigration sentiment, and hate crimes, including on college campuses, have increased recently. Although African American (70%) and Hispanic/Latinx people (56%) report considerable discrimination exposure, there remains a critical need for research examining the pathways through which racism-related stress affects health. Here, we developed an ecological, intensive longitudinal design leveraging an independent biosignal of stress arousal collected from a wearable sensor. Our method documents both increased simultaneous negative emotion and stress arousal among African American, Latinx, and African students in response to racism-related stress. These findings provide support for allostasis-based theories of mental and physical health via a naturalistic assessment of emotional and physiological responding to real-life social experiences.
Gender stereotypes can explain the gender-equality paradox
Authors: Breda Thomas , Jouini Elyès , Napp Clotilde , Thebault Georgia
Published: November 2020

Significance

Recent research has found that the strong underrepresentation of women in math-related fields is more pronounced in more egalitarian and more developed countries. This pattern has been called the “gender-equality paradox.” We show that stereotypes relating math primarily to men are actually stronger in more egalitarian and more developed countries and that they mediate the link between development and segregation across fields of study. The mechanisms connecting socioeconomic development to the strengthening of these stereotypes and the gendering of math-related fields are discussed. Results suggest that gender occupational segregation can be reduced but will not decrease by itself as societies become more developed. Appropriate policies are therefore needed to limit this segregation or its impact on gender inequality.
A hybrid approach reveals the allosteric regulation of GTP cyclohydrolase I
Authors: Ebenhoch Rebecca , Prinz Simone , Kaltwasser Susann , Mills Deryck J. , Meinecke Robert , Rübbelke Martin , Reinert Dirk , Bauer Margit , Weixler Lisa , Zeeb Markus , Vonck Janet , Nar Herbert
Published: November 2020

Significance

We present a comprehensive structural study, which shows the human GCH1 and GCH1−GFRP complexes in all states (apo, ligand bound, partially and fully inhibited). We observed local rearrangements in the allosteric pocket upon BH4 binding, which result in drastic changes in the quaternary structure of the enzyme leading to a more compact, tense form in the inhibited protein. Inhibition of the enzymatic activity is not a result of hindrance of substrate binding, but rather a consequence of accelerated substrate binding kinetics as shown by STD-NMR and site-directed mutagenesis. We propose a dissociation rate-controlled mechanism of allosteric, noncompetitive inhibition, which could stimulate further research toward the development of GCH1 inhibitors to treat neuropathic and inflammatory pain disorders.

Advances in technological developments in the current 4.0 era require retail businesses to increase sales and develop marketing strategies. Determination of which products are widely sold and which products will be propagated in inventory is very important for retail businesses to prevent data accumulation. Data Mining has been widely used to conduct analysis, determine patterns and associations. In this paper, we propose a basic methodology for calculating association analysis with apriori algorithms used to process the most sold products and which products will be propagated in the sales inventory. The results of this study are the calculation model of high-frequency pattern analysis and the formation of association rules and item set combination patterns resulting from the sale of fruit products from retail with the highest support and confidence of the most sold fruit products. Therefore the apriori algorithm can help develop sales strategies.

Liwa Botanical Garden is located in West Lampung Regency and is one of the conservation of ornamental plants that presents the rich flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a natural orchid. Until now, disease infections are still a major obstacle in efforts to preserve and develop the potential of natural orchids. Based on previous research, it is known that several individual orchid collections from Liwa Botanical Garden show symptoms of bacterial infection. This pathogen will infect orchids and cause soft rot disease. This research was conducted to determine the identification of diseases and efforts to protect natural orchids against bacterial infections in the Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the natural orchids of Liwa Botanical Garden to bacterial infections was to show symptoms of soft rot disease, i.e Bulbophyllum sp., Dendrobium crumenatum, Dendrobium montanum, Pholidota sp., and Vanilla sp. The type of orchid that shows the most symptoms of bacterial infection is Vanilla sp. 11 samples, and Pholidota sp. and Dendrobium crumenatum with 3 samples each. The type of orchid that shows the most symptoms is Flickingeria sp. a total of 8 samples. The natural type of the Liwa Botanical Garden which is most susceptible to bacterial infections is Pholidota sp. and Vanilla sp. with disease intensity of 10% and 7.7%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of natural orchids in Liwa Botanical Garden.

Genetic algorithmhasvarious process are carried out to get optimal results in solving the problem of traveling salesman problemTravelling salesman problem (TSP) as known as combinatorial NP problem. Salesman given a map that he has accomplished all cities only once by minimized the total of distance and he has to return to the first city. By describing the taxonomy in genetic algorithm, it can avoid confusion in understanding the various classifications that exist in the genetic algorithm operator. This paper explains one of the parts from genetic algorithm is crossover. Crossover being important step in genetic algorithm. Commonly mechanism crossover replaces two selected chromosome which part from two parent’s individual randomly position, generate random number interval 0-1. Crossover occur for each individual by determining the probability of the crossover. If the probability crossover is smaller than random number, there is no crossover process. Partially mapped crossover is part of the taxonomy of genetic algorithms whose implementations can be applied in a variety of problem solving including in the travelling salesman problem. The test results of this researchusing pc 0.25 and pm 0,1 with tsp eil51 data, it was found that the optimal route average value was 4069.34 and the best fitness average was 2.46E-04, while for the eil76 test data the optimal route average value was 6844.4. and the average best fitness value of 1.46E-04.

Published: November 2020

The quality of the images collected by the coastal zone video surveillance equipment is seriously degraded due to the sea fog, which directly affects the analysis of the image. Therefore, the study of the costal image dehazing method is of great significance to the related research of the coastal zone. Costal image has the characteristics of large sky area and monotonous color. The traditional method based on atmospheric scattering physics model is not suitable for this kind of image for block effect and color distortion. In this paper, we introduce the generative adversarial mechanism into sea fog image defogging, and propose a coastal image dehazing network based on it. The proposed model includes a generative network and a discriminative model, and is trained by adversarial mechanism. The generative model is composed of multi-scale feature extraction module and residual connection module. The discriminative network consists of two sub-networks of receptive field of different sizes.

Published: November 2020

Aspect level sentiment analysis is a more fine-grain task compared to document level and sentence level. The aim of the task is to identify the sentiment polarity expressed to the given aspect in the text. In this paper, we propose a residual aspect fusion network with attention for the aspect level sentiment classification. In this network, bidirectional GRU is used to collect semantic information of both sentence words and aspect words, and then attention mechanism is applied to construct aspect vectors for each word in the sentence. In the residual fusion module, the model fuses the aspect information and sentence information together by residual connection structure, in which position weight is applied to utilize the position information of aspect words. At the end of the model, Transformer encode layer is used to extract global feature and fully connected layers are used as the classifier. We train and test the network on SemEval2014 task 4 (Restaurant and Laptop) and Twitter datasets, and the experiments demonstrate that our model performs better than previous methods.
