Análisis Psicométrico Preliminar de la Escala de Actitudes Percibidas en Terapia hacia Personas Lesbianas, Gays y Bisexuales
Authors: Esteban Caleb , González Rivera Juan A. , Francia Martínez Margarita
Published: August 2021

En Puerto Rico, al igual que otros países, se viven actitudes negativas hacia las minorías sexuales y de género, especialmente hacia personas lesbianas, gay y bisexuales (LGB). Diversos estudios en la isla han encontrado actitudes negativas y distancia social de parte de profesionales de la psicología hacia la comunidad LGB. Sin embargo, no se tenía información sobre cómo las personas LGB percibían las actitudes en el espacio de terapia. Al no existir una escala para medir este fenómeno, se construye la Escala de Actitudes Percibidas en Terapia hacia Personas Lesbianas, Gays y Bisexuales. La muestra fue no probabilística y constituida por 104 participantes que se identificaban como LGB. Al revisar la distribución de los ítems de acuerdo a su carga factorial se identificaron dos factores: “Actitud Negativa” y “Actitud Positiva”. Tanto la escala total, como los dos factores, mostraron coeficientes aceptables. En síntesis, los hallazgos preliminares de este estudio demostraron que la escala tiene la capacidad de examinar las actitudes de los terapeutas.
Endonasal Septal Perforation Repair: Free Mucosal Graft With Lyoplant® Bioscaffold
Authors: Yi Hee Jun , Sim Jaeyeop , Choi Jae Hyuk , Choi Nayeon , Kim Jeong Hong
Published: August 2021

Nasal septal perforation (NSP) is a common complication of nasal surgery and can cause nasal obstruction, crust, and epistaxis. Many surgical methods have been introduced for repair of NSP, among which mucosal flap and artificial dermis have been widely used. However, mucosal graft can shrink and migrate and is difficult to fix at the perforation site. Mucosal advancement flap requires a wide extent of septal mucosa dissection, and artificial dermis can cause nasal obstruction because of its bulkiness and lower biocompatibility than autologous mucosa. To overcome these problems, we reported successful outcomes in 4 cases of small NSP by free mucosal graft with bioscaffold.
Local Political Power and Social Protection Policies for Elderly People in the Portuguese Context - An Exploratory Study
Authors: Maurício Cezarina , Matias Liliete
Published: August 2021

Since the Carnation Revolution in April of 1974, and the consequent approval of the Portuguese Republic Constitution (1976), the country’s legislative trend has been geared towards the expansion of local government power, in Portugal. This issue has acquired new relevance recently, with the new reconfiguration of the political decentralization process, through Law No. 50/2018, of 16th August. This is a gradual process, still ongoing, and delayed by the current pandemic situation. Local authorities play a decisive role in the country's development, both in the present and in the past. Initially focused on creating essential and basic infrastructures for the people, now includes other concerns, such as social protection. The definition and implementation of social policies, targeted to different populations, has become an essential axis of action, in a country marked by territorial disparities and an aging population. This study aims to understand the role of local administration in the characterization of social policies targeted at senior populations. The present work is a study of qualitative and explorative nature. Using documentary research and content analysis, we identified and characterized the measures aimed at the senior population implemented by two municipalities (Gouveia and Ourém). The analysis of the results allows us to conclude that the municipalities implemented measures that target the elderly population directly. Seniors also benefit from other measures, applicable to other age groups. It is important that the discussion focuses on these measures and the achievement of their goals. Measures to protect the elderly population are urgent, especially in a southern European country like Portugal, that has an ageing population, with a considerable increase in people aged 65 and over.
Review of the Evidence Landscape on the Risk Communication and Community Engagement Interventions Among the Rohingya Refugees to Enhance Healthcare Seeking Behaviours in Cox's Bazar
Authors: Yonally Emilie , Butler Nadia , Ripoll Santiago , Tulloch Olivia
Published: August 2021

This report is the first output in a body of work undertaken to identify operationally feasible suggestions to improve risk communication and community engagement efforts (RCCE) with displaced Rohingya people in Cox’s Bazar. Specifically, these should seek to improve healthcare seeking behaviour and acceptance of essential health services in the camps where the Rohingya reside. It was developed by the Social Science in Humanitarian Action Platform (SSHAP) at the request of the UK Foreign, Commonwealth & Development Office in Bangladesh. As a first step in this process, this review paper synthesises and assesses the quality of evidence landscape available in Cox’s Bazar and how the Rohingya seek and access healthcare services in Cox’s Bazar and presents the findings from key informant interviews on the topic. Findings are structured in five discussion sections: (1) evidence quality; (2) major themes and variations in the evidence; (3) learnings drawn and recommendations commonly made; (4) persistent bottlenecks; and (5) areas for further research. This synthesis will inform a roundtable discussion with key actors working for the Rohingya refugees to identify next steps for RCCE and research efforts in Cox’s Bazar to improve health outcomes among the Rohingya.
Solving Capacitated Vehicle Routing Problem (CVRP) for the Environments with Circular Obstacles
Authors: Karakoç Mehmet , Ugur Aybars
Published: August 2021

In capacitated vehicle routing problem (CVRP), a fleet of vehicles with a certain capacity starts at a central depot and returns to this starting point after serving some customers by using the optimal set of routes with the minimum cost. However, in real-life, environments may include obstacles such as holes, machines, or trees of different sizes. In this research, a CVRP extension is proposed that is the problem of the classical one for the environments with various sized circular obstacles. To solve this problem, a hybrid meta-heuristic algorithm based on genetic algorithms improved by a local search was developed. Additionally, a visual simulation tool was designed to place obstacles and locations in the working space. The developed algorithm was tested for different customer-obstacle counts and obstacle sizes with various obstacle occupancies in the environment. The results obtained are presented and the problem’s potential applications are discussed.
The “Emigration Commission”: The Chief Representative for the evacuation of the Polish and Jewish population from the Ukrainian Soviet Socialist Republic and the evacuation apparatus: A description
Authors: Hryciuk Grzegorz
Published: August 2021

The changes of political borders between Poland and the Soviet Union in 1944–1945 were accompanied by a relocation campaign lasting until autumn 1946 and affecting the Polish and Jewish populations of Eastern Galicia, Volhynia and Northern Bukovina. An agreement for mutual resettlement of Poles, Jews and Ukrainians, formally referred to as evacuation, was concluded on 9th September 1944 in Lublin between the Polish Committee of National Liberation and the Ukrainian Soviet Socialist Republic. The organisation of the relocation was entrusted to a special apparatus subordinated to evacuation representatives of both sides. The Chief Representative for the evacuation of the Polish and Jewish population from the Ukrainian Soviet Socialist Republic was based in Lutsk. Initially, he oversaw seventeen and then eighteen regional representatives in larger cities located in the so-called western oblasts of the Ukrainian SSR. Together with representatives of the Ukrainian side they were to carry out a registration campaign and organise transport for the relocated population and its possessions. The relocation apparatus began to be organised by a group of employees who arrived in Lutsk from Lublin in October 1944 with the first Representative, Stanisław Pizło. The process was viewed with distrust and hostility by the Poles, who were reluctant to leave their homeland. The several hundred staff of the resettlement apparatus struggled, similarly to the local population, with numerous problems relating to provisions and subsistence. The Soviet security services saw many officials working for the Representative as individuals hostile to the Soviet authorities. Consequently, Polish officials were quite often arrested, having been accused of collaborating with the Polish independence underground and of sabotaging the resettlement campaign. A lack of a sense of security led to a considerable staff turnover among the resettlement staff. As most of the people entitled to be evacuated from the various resettlement regions left, from the second half of 1945 the staff working for the evacuation apparatus were gradually dismissed. The transfer of population ended in November 1946 and the final protocol closing the post-war resettlements under the agreement of 9th September 1944 concluded between the Polish Committee of National Liberation and the government of the Ukrainian SSR was signed in May 1947.
Испытание голодом 1946–1947 годов в памяти жителей Восточной Галиции
Authors: Jakimowicz Marcelina , Zubowski Piotr
Published: August 2021

Массовый голод — это экстремальное, трагическое и разрушительное испытание для человека и общества. В 1946–1947 годах волна голода хлынула на Советскую Украину, она затронула более четырех миллионов человек (на довоенных и послевоенных территориях УССР) и привела к гибели более ста тысяч человек. Послевоенный голод, как и Голодомор 1932–1933 годов, был не только результатом засухи или недавно завершившейся войны, но главным образом коллективизации и борьбы против владельцев аграрных хозяйств. В статье, основанной на биографических рассказах, собранных в ходе полевых исследований в Восточной Галиции, представлены воспоминания жителей о волне послевоенного голода. Собеседники рассказывали о путях выживания, обращали внимание на важность семьи и соседского сообщества, а также приводили примеры несправедливости и беспощадности советской власти. Восточная Галиция в межвоенный период принадлежала территориям Второй Польской Республики, однако рассказчики часто связывали волну послевоенного голода с Голодомором 1932–1933 годов, который является одним из самых трагических исторических событий в истории украинской нации. Послевоенный голод, таким образом, в воспоминаниях респондентов предстал как одна из многих волн голода — самого важного испытания в истории украинской нации.

This study of mosquitoes in Lika, geographically, geologically and climatically a very specific region, was conducted to gain insight into the composition and relative abundance of the mosquito fauna, as well as to check for the possible presence of invasive species. Sampling took place from July to September 2020. Mosquito larvae were captured from medium and small breeding sites using a 25 cm diameter net and a plastic dipper. Adult specimens were sampled in both urban and rural areas using CO2 baited CDC traps, CO2 baited BG Sentinel traps with BG Lure and human landing catch. The study was conducted at 69 sites. We collected 5,126 specimens (100 adults and 5,026 larvae) and demonstrated the presence of 16 mosquito species. CDC traps were almost five times more effective (quantity and quality) than BG Sentinel traps. The most common mosquito taxa caught in Lika were Culex pipiens complex (78.36% of all larvae) and Ae. geniculatus (30.26% of all adults). Both invasive mosquito species present in Croatia, Aedes albopictus and Ae. japonicus, were recorded, with Ae. albopictus being detected in Lika for the first time. Aedes japonicus was widespread, recorded in 23 localities. According to molecular analysis, only An. maculipennis s.s. was confirmed in the An. maculipennis complex. Within the Cx. pipiens complex, both Cx. pipiens biotypes, pipiens and molestus were confirmed together with one single hybrid specimen. Analysis of mosquito occurrence with regard to altitude shows that most samples and species were collected between 601 and 700 m a.s.l., although the Shannon evenness index and Hill’s index show the highest value in the range of 901 to 1140 m a.s.l. In this systematic study on the mosquito fauna in Lika, a significant species diversity, including invasive species, was found.

Here we present a first record of Baetis vardarensis Ikonomov, 1962 in Croatian freshwater habitats. The species was collected in February and March 2020 at two sites in the Sava River. With this record, Croatian mayfly species richness increased to a total of 85 species. In addition, one of the species previously known only from literature, Kageronia fuscogrisea (Retzius, 1783), was confirmed in Croatia. The species was collected in the Rečica River, in March 2020. These results confirm that our knowledge about mayfly fauna in different regions of Balkan Peninsula is still incomplete and is increasing with systematic studies.

Based on our own research carried out from 2013 to 2019 and literature data, this study presents for the first time a comprehensive floristic list of Mt Svilaja (max. 1508 m a.s.l.). It contains 1285 taxa classified within 502 genera and 109 families. Of these, 552 taxa are listed for the first time for Svilaja. Out of 733 taxa recorded previously, the presence of 128 taxa has not been confirmed. Poaceae (8.79%), Asteraceae and Fabaceae (8.72% each) had the highest number of taxa, with the largest number of taxa within the genera Trifolium (23 taxa), Carex (20) and Centaurea (17). Hemicryptophytes (43.35%) and therophytes (25.45%) prevailed, and Mediterranean (23.27%), southern European (20.83%) and Eurasian (17.43%) plant taxa dominated. Altogether, there were 76 endemics (5.91%), mostly of Illyrian-Adriatic origin, 34 endangered (CR, EN, VU) taxa (2.65%), and 155 strictly protected taxa according to Croatian law (12.06%). Among the endemics, the presence of Scabiosa delminiana Abadžić must be stressed. Mt Svilaja is characterized by rich orchid flora (51 taxa, 3.97%), and features Epipactis placentina Bongiorni & Grünanger, the only site found in Croatia that does. Although as many as 34 invasive taxa have been recorded, their presence is mostly limited to anthropogenic habitats.

The purpose of this study was to determine the effect of aflatoxin content of 9.58 ppb in feed on gastrointestinal biometrics and weight gain of laying hens in the early growth period. Thirty-six day old chicks (DOC) were used in this study and were divided into two groups P0 and P1. P0 (control group) was fed with 100% basal diet and P1 (treatment group) was fed a diet with a composition of 80% basal feed + 20% aflatoxin-containing feed. After the DOC was adapted, the first feeding containing aflatoxin was given from the 20th day to the 60th day. Data collection was carried out three times, namely the 20th, 40th, and 60th days. At the end of each period, the chickens would be euthanized to collect data on the weight and length of the digestive tract and body weight. Weight gain with time increased, but had no significant effect (p>0.05) between the control and treatment groups. Body weight continues to increase because the body's homeresis function is still running well. Observations on gastrointestinal biometrics showed significant differences (p<0.05) in oesophagus weight, proventriculus weight, ventriculus weight, jejunum weight, ileum weight and length, and cecum weight because aflatoxins have a direct effect on the digestive tract they pass. The conclusion of this study was that the provision of 20% aflatoxin-containing feed did not affect weight gain but had shown an effect on the biometrics of several gastrointestinal tracts.

Published: August 2021

The outflow tract of crocodilians resembles that of birds and mammals as ventricular septation is complete. The arterial anatomy however, presents with a pulmonary trunk originating from the right ventricular cavum, and two aortae originating from either the right or left ventricular cavum. Mixing of blood in crocodilians cannot occur at ventricular level as in other reptiles, but instead takes place at aortic root level by a shunt, the Foramen of Panizza, the opening of which is guarded by two facing semilunar leaflets of both bicuspid aortic valves. Methods. Developmental stages of Alligator mississipiensis, Crocodilus niloticus and Caiman latirostris, have been studied. Results and Conclusions. The outflow tract septation complex can be divided into 2 components. The aorto-pulmonary septum divides the pulmonary trunk from both aortae, whereas the interaortic septum divides the systemic from the visceral aorta. Neural crest cells are most likely involved in the formation of both components. Remodeling of the endocardial cushions and both septa results in the formation of bicuspid valves in all three arterial trunks. The foramen of Panizza originates intracardially as a channel in the septal endocardial cushion.

Published: August 2021

The rapid increase in population along with the economic activities led to rapid depletion of natural resources. Land use studies help us analyze the impacts of urban development on environment. Given the political upheavals in Afghanistan, this study aims to analyze how urban development evolved from 1978 to 2018 in six major cities- Kabul, Kandahar, Kunduz, Herat, Mazar-e Sharif and Jalalabad- in Afghanistan using Landsat Satellite Images. This study is based on quantitative approach. ArcGIS 9.4 software was used to synchronize the Landsat Satellite Images within the area of study. The results of the study show that the Annual rate of urban land expansion in Afghanistan was the lowest (average 1.07 square kilometers per year) during the military presence of Soviet Union in Afghanistan while it was the highest (3.35 square kilometers per year) from 2001 to 2018 due to the military presence of US-led NATO forces, relative security and rapid economic activities in Afghanistan. The authors believe that this study could be further explored if other inter-connected factors, e.g., the role of culture, literacy, immigration etc., are incorporated into the study of urban development processes in Afghanistan.
A Study of Junior High School English Writing Teaching Based on Scaffolding Theory
Authors: Wang Rong
Published: August 2021

Writing, as an important language skill, receives much attention in language teaching in junior high school. Traditional writing teaching always asks students to remember examples by heart to collect language resources, which plays no real function to improve students’ writing skills. Thus, it is necessary to design the writing class in an effective way. This thesis aims to illustrate how to build scaffolding for students during the process approach to writing and help them complete the writing tasks. This method focuses on the process of building scaffolding to facilitate the writing process, rather than only emphasizing the outcome. Through the classroom observation and cases analysis, the author further explores the scaffolding theory in English writing teaching in junior high school.

Simultaneous mapping of coastal topography and bathymetry from a lightweight multicamera UAS
Authors: Brodie Katherine , Bruder Brittany , Slocum Richard , Spore Nicholas
Published: August 2021

A low-cost multicamera Unmanned Aircraft System (UAS) is used to simultaneously estimate open-coast topography and bathymetry from a single longitudinal coastal flight. The UAS combines nadir and oblique imagery to create a wide field of view (FOV), which enables collection of mobile, long dwell timeseries of the littoral zone suitable for structure-from motion (SfM), and wave speed inversion algorithms. Resultant digital surface models (DSMs) compare well with terrestrial topographic lidar and bathymetric survey data at Duck, NC, USA, with root-mean-square error (RMSE)/bias of 0.26/–0.05 and 0.34/–0.05 m, respectively. Bathymetric data from another flight at Virginia Beach, VA, USA, demonstrates successful comparison (RMSE/bias of 0.17/0.06 m) in a secondary environment. UAS-derived engineering data products, total volume profiles and shoreline position, were congruent with those calculated from traditional topo-bathymetric surveys at Duck. Capturing both topography and bathymetry within a single flight, the presented multicamera system is more efficient than data acquisition with a single camera UAS; this advantage grows for longer stretches of coastline (10 km). Efficiency increases further with an on-board Global Navigation Satellite System–Inertial Navigation System (GNSS-INS) to eliminate ground control point (GCP) placement. The Appendix reprocesses the Virginia Beach flight with the GNSS–INS input and no GCPs.
Mapping the Relative Pollination Potential of Iran Using Multi-Criteria Evaluation and The Lonsdorf Model
Authors: Rahimi ehsan , Barghjelveh Shahindokht , Dong Pinliang
Published: August 2021

Since very little attention has been paid to pollination service in Iran, especially its mapping, there is little information about the areas where wild bees are present. Therefore, in this study, we used two models based on expert opinion that does not need the presence points of pollinating bees to estimate pollinating service. The Lonsdorf (Lonsdorf et al., 2009) model, simply considers the potential of land covers in providing nesting habitat and floral resources for mapping pollination services in different landscapes. In addition to considering the potential of land covers in providing pollination service, the multi-criteria evaluation model uses additional factors such as altitude, climate, roads, and rivers network. The results of the Lonsdorf model showed that the majority of Iran have a low potential for providing pollination service and only three percent of the northern and western parts of Iran have high potential. However, the results of the multi-criteria evaluation model showed that 23% of Iran has a high potential to provide pollination services that cover most of the northern and southern parts of the country. The difference in the results of the models was due to their attention to the factors affecting the probability of the presence of pollinators in Iran because the Lonsdorf model does not pay attention to factors such as altitude and climate in modeling, while these factors significantly affect the activity of bees. Therefore, the present study acknowledges the results of the multi-criteria evaluation model for pollination service mapping in Iran and emphasizes that the approach adopted in the Lonsdorf model for accurate estimation of pollination service is not complete and needs correction.
Adult-Onset Mast Cell Activation Syndrome Following Scombroid Poisoning a case report and review of the literature
Authors: Brock Isabelle , Eng Nicole , Maitland Anne
Published: August 2021

Mast Cell Activation syndrome (MCAS) is a clinical condition, defined by the combination of 1) typical symptoms, 2) laboratory abnormalities and 3) response to treatment. Patients present with episodic symptoms of aberrant mast cell activation, such as abdominal cramping, asthma, hypotensive episodes, tachycardia, anaphylaxis, unexplained arrhythmias, and neurologic/psychiatric symptoms. Both clonal and nonclonal mast cell activation syndromes have been described, with a greater prevalence of non-clonal MCAS among the pediatric and adult population. Numerous extrinsic triggers of mast cell activation (MCA) are described, but recent reports point to nonatopic triggers, as the predominant, extrinsic stimulants of MCA in the adult population. The etiology of MCAS is unclear, though recent studies point to the disruption of the epithelium by infection, toxic exposures or physical trauma, and perturbation the tight regulation of these innate immune cells, associated to the epithelial borders. Here we describe a geriatric patient with adult onset MCAS, following a significant toxic exposure, scombroid poisoning. We also review the relevant literature regarding MCAS diagnosis and management as well as potential mechanisms for this hypersensitivity syndrome in adults.
Evaluation of the Efficacy of Postoperative Triamcinolone in Endoscopic Dacryocystorhinostomy using Lacrimal Symptom Questionnaire
Authors: KAPTI HASAN BURHANETTİN , KORKMAZ HAKAN
Published: August 2021

Purpose: To evaluate the effect of postoperative nasal triamcinolone spray use in primary endoscopic dacryocystorhinostomy using The Lacrimal Symptom Questionnaire .Methods: This study included a series of 50 consecutive retrospective cases with primary endoscopic dacryocystorhinostomy and with silicone stent implantation who were followed up for 6 months postoperatively. Patients using nasal triamcinolone spray for 3 months postoperatively were included in the triamcinolone group. Patients not using triamcinolone were included in the control group. Lacrimal stents were removed 3 months postoperatively. The Lacrimal Symptom Questionnaire (Lac-Q) was performed in the preoperative and postoperative 6th month. Anatomical success, functional success, and changes in lacrimal symptom and social impact scores were compared between the two groups 6 months after surgery.Results: Results of 48 endoscopic dacryocystorhinostomies performed on 48 patients (23 triamcinolone group, 25 control group) meeting the inclusion criteria were analyzed. The anatomical success rate (95.7% vs. 84.0%, p = 0.350) and the functional success rate (91.3% vs. 76.0%, p = 0.249) were higher in the triamcinolone group, but this difference was not statistically significant. No complications were observed in the triamcinolone group, whereas complications developed in two patients in the control group (p = 0.490).

Because Pancharatnam-Berry (PB) geometrical phase can only be generated in the co-polarized reflection coefficient under circular polarized (CP) incidence for a reflective metasurface, designing a reflective PB coding metasurface must be based on an appropriate polarization conversion metasurface (PCM), which can realize CP-maintaining reflection. In this work, to design a reflective 2-dit PB coding metasurface for radar cross section (RCS) reduction, an ultra-wideband PCM is proposed at first, the simulated results show that the PCM can realize ultra-wideband CP-maintaining reflection from 8.6 to 35.9 GHz; moreover, PB phase will be generated in its co-polarized reflection coefficient by rotating its unit structure. Thus based on the PCM, an ultra-wideband reflective 2-dit PB coding metasurface is constructed successfully. The simulation and experiment results show that the coding metasurface has excellent performance in RCS reduction under arbitrary polarized incidences, compared with a pure metallic plate with the same size, its RCS can be reduced more than 10dB in the frequency band 8.2-35.2GHz with a relative bandwidth of 124.4%.

Background: While immune checkpoint inhibition (ICI) has revolutionized the treatment of metastatic cutaneous melanoma, no standard treatments are available for patients with metastatic uveal melanoma (UM). Several locoregional therapies are effective in the treatment of liver metastases, such as percutaneous hepatic perfusion with melphalan (M-PHP). The available literature suggests that treatment with ICI following locoregional treatment of liver UM metastases can result in clinical response. We hypothesize that combining M-PHP with ICI will lead to enhanced antigen presentation and increased immunomodulatory effect, improving control of both hepatic and extrahepatic disease. Methods: Open-label, single center, phase Ib/randomized phase II trial, evaluating the safety and efficacy of the combination of M-PHP with ipilimumab (anti-CTLA-4 antibody) and nivolumab (anti-PD-1 antibody) in patients with unresectable hepatic metastases of UM in first line treatment, with or without limited extrahepatic disease. Primary objective is to determine safety, toxicity and efficacy of the combination regimen, defined by maximum tolerated dose (MTD) and progression-free survival (PFS) at one year. Secondary objectives include overall survival (OS) and overall response rate (ORR). A maximum of 88 patients will be treated in phase I and phase II combined. Baseline characteristics will be described with descriptive statistics (t-test, Chi-square test). To study the association between risk factors and toxicity a logistic regression model will be applied. PFS and OS will be summarized using Kaplan-Meier curves.Discussion: This is the first trial to evaluate this treatment combination by establishing the maximum tolerated dose and evaluating the efficacy of the combination treatment. M-PHP has shown to be a safe and effective treatment for UM patients with liver metastases and became the standard treatment option in our center. The combination of ICI with M-PHP is investigated in the currently described trial which might lead to a better treatment response both in and outside the liver.

BackgroundDuring endotracheal intubation training, only providing verbal guidance to students may result in inadequate recognition of the inner larynx and cause delays in mastering endotracheal intubation. Therefore, we introduced a deliberate practice approach to the education of residents in endotracheal intubation. For this purpose, a video laryngoscope was used to give the residents detailed feedback of the anesthesiology faculty. We hypothesized that if the anesthesiology faculty could provide sufficient and precise feedback of the larynx through the video monitor, the residents’ intubation skills would be retained for a more extended period.MethodsThis cluster randomized controlled study enrolled first-year residents who completed a two-month rotation at our department. Each rotation group (2–4 residents) was assigned to the Macintosh laryngoscope (ML) group or the McGRATH MAC video laryngoscope (MML) group. Endotracheal intubation skills were evaluated on a simulated mannequin immediately after the rotation, three months later, and six months later. The primary endpoint was the time required for intubation. The secondary endpoint was the percentage of glottic opening (POGO) score.ResultsForty-six residents participated in this study and were assigned to the ML group (n = 23) or the MML group (n = 23). The time required for intubation was significantly shorter in the MML group than in the ML group. The POGO score did not show any significant differences between the two groups; however, the POGO score of the MML group had a relatively narrower confidence interval than the ML group.ConclusionsWhen comparing endotracheal intubation training using the Macintosh laryngoscope and video laryngoscope, the McGRATH MAC video laryngoscope shortened the intubation procedure and facilitated long-term skill retention.Trial registrationClinical registry and trial number, URL: https://www.umin.ac.jp, UMIN000036643 date of registration: 2019/05/03, This study was retrospectively registered.

Here we propose a novel de-noising method to improve the outcome of heart sound (HS)-based heart condition identification. We applied Dual Tree Complex Wavelet Transform (DTCWT) in collaboration with Adaptive Neuro Fuzzy Inference System (ANFIS) classifier. The method consisted of three steps. First, preprocess to eliminate 50 Hz noise. Second, application of DTCWT to de-noise and reconstruct time-domain HS signal. Third, evaluation of ANFIS on total 2735 HS recordings from an international dataset (PhysioNet Challenge 2016). The signal-to-noise ratio (SNR) with DTCWT was significantly improved (p < 0.001) as compared to original HS recordings. Quantitatively, there was a 11% increase in SNR after DTCWT, representing a significant improvement in de-noising HS. In addition, the ANFIS, using six time-domain features, resulted in 55–86% precision, 51–98% recall, 53–86% f-score, and 54–86% MAcc in comparison to other attempts on the same dataset. Therefore, DTCWT is a successful technique in de-noising information such as HS recordings. The adaptive property of ANFIS exhibited capability in classifying HS recordings.

Purpose To provide a direct evidence for the current practice of prescribing antiemetic with aprepitant, dexamethasone and ondansetron in patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) receiving concurrent chemoradiotherapy (CCRT). Methods Treatment-naïve LA-HNSCC patients received intensity-modulated radiotherapy with concomitant cisplatin 100 mg/m² every 3 weeks for two cycles. All patients were given orally aprepitant 125 mg once on d1, then 80mg once on d2-5; ondansetron 8 mg once on d1; and dexamethasone 12 mg once on d1, then 8mg on d2-5. The primary endpoint was complete response (CR). Pursuant to δ=0.2 and α=0.05, the expected CR rate was 80%. Results A total of 43 patients with LA-HNSCC were enrolled. The median age was 53 years old, and 86.0% were male. All patients received radiotherapy and 86.0% of patients completed both cycles as planned. The overall CR rate was 86.0% (95% CI: 72.1-94.7). The CR rates for cycles 1 and 2 were 88.4% (95% CI: 74.9-96.1) and 89.2% (95% CI: 74.6-97.0). The complete protection rate in the overall phase was 72.1% (95% CI: 56.3-84.7). The emesis-free response and nausea-free response in overall phase were 88.4% (95% CI: 74.9-96.1) and 60.5% (95% CI: 44.4-75.0), respectively. The adverse events related to antiemetics were constipation (65.1%) and hiccups (16.3%), but both were grade 1-2. There was no grade 4 or 5 treatment-related adverse event with antiemetic usage. Conclusion The addition of aprepitant into ondansetron and dexamethasone provided effective protection from nausea and emesis in patients with LA-HNSCC receiving CCRT.

Classification is one of the most important and widely used issues in machine learning, the purpose of which is to create a rule for grouping data to sets of pre-existing categories is based on a set of training sets. Employed successfully in many scientific and engineering areas, the Support Vector Machine (SVM) is among the most promising methods of classification in machine learning. With the advent of big data, many of the machine learning methods have been challenged by big data characteristics. The standard SVM has been proposed for batch learning in which all data are available at the same time. The SVM has a high time complexity, i.e., increasing the number of training samples will intensify the need for computational resources and memory. Hence, many attempts have been made at SVM compatibility with online learning conditions and use of large-scale data. This paper focuses on the analysis, identification, and classification of existing methods for SVM compatibility with online conditions and large-scale data. These methods might be employed to classify big data and propose research areas for future studies. Considering its advantages, the SVM can be among the first options for compatibility with big data and classification of big data. For this purpose, appropriate techniques should be developed for data preprocessing in order to covert data into an appropriate form for learning. The existing frameworks should also be employed for parallel and distributed processes so that SVMs can be made scalable and properly online to be able to handle big data.

One of the main traits of invasive ants is the formation of supercolonies, large networks of polygynous nests lacking intraspecific competition, which allows them to reach high densities that facilitate their spread. However, different supercolonies exhibit different success in expanding along the world. Here, we explore whether the main chemical defensive compound of the Argentine ant could play a role in the differential invasiveness of supercolonies. We assessed differences in the amount of iridomyrmecin among supercolonies in the native range and in three invasive supercolonies: the Main supercolony (the most extended worldwide), and the Corsican and the Catalonian supercolonies (both with a restricted local distribution in Europe). We found that even if the amount of iridomyrmecin varied greatly between invaded regions in the three supercolonies in Europe and the native supercolonies in South America, the differences did not seem related to the success of invasion. The amount of iridomyrmecin of the Main supercolony was the lowest while the highest corresponded to the Corsican supercolony, with the Catalonian having intermediate values. This suggests that the success of a given invasive supercolony may not be explained by higher quantities of this defensive compound. Alternatively, reducing iridomyrmecin quantities in the invasive range could lead to more investment in other fitness traits that increase the invader's competitive ability. Our results open the way for exploring the contribution of defensive compounds in the competitive ability and spread of this global invader.
