Pregnancy-related inappropriate sinus tachycardia: A cohort analysis of maternal and fetal outcomes

Background Little literature exists regarding the syndrome of inappropriate sinus tachycardia during pregnancy. We aimed to further understand the natural history of inappropriate sinus tachycardia in pregnancy, and to explore maternal and fetal outcomes. Methods A retrospective, observational cohort analysis of 19 pregnant women who presented with inappropriate sinus tachycardia. Results 42% attended the emergency department on more than one occasion with symptoms of inappropriate sinus tachycardia; 32% required hospital admission and 26% required pharmacological therapy. There were no maternal deaths, instances of heart failure or acute coronary syndrome, and no thromboembolic or haemorrhagic complications during pregnancy. Rates of caesarean section were similar to the background rate of our unit (32% and 27%, respectively). Rates of induction were notably elevated (58% vs 25%). Conclusion Inappropriate sinus tachycardia in pregnancy is associated with high rates of hospitalization and induction of labour, which may not be mandatory given the clinical findings in this group of women.
Mass of different snow crystal shapes derived from fall speed
measurements

Abstract. Meteorological forecast and climate models require good knowledge of the microphysical properties of hydrometeors and the atmospheric snow and ice crystals in clouds. For instance, their size, cross-sectional area, shape, mass, and fall speed. Especially shape is an important parameter in that it strongly affects the scattering properties of ice particles, and consequently their response to remote sensing techniques. The fall speed and mass of ice particles are other important parameters both for numerical forecast models and for the representation of snow and ice clouds in climate models. In the case of fall speed, it is responsible for the rate of removal of ice from these models. The particle mass is a key quantity that connects the cloud microphysical properties to radiative properties. Using an empirical relationship between the dimensionless Reynolds and Best numbers, fall speed and mass can be derived from each other if particle size and cross-sectional area are also known. In this work, ground-based in-situ measurements of snow particle microphysical properties are used to analyse mass as a function of shape and the other properties particle size, cross-sectional area, and fall speed. The measurements for this study were done in Kiruna, Sweden during snowfall seasons of 2014 to 2019 and using the ground-based in-situ instrument Dual Ice Crystal Imager (D-ICI), which takes high-resolution side- and top-view images of natural hydrometeors. From these images, particle size (maximum dimension), cross-sectional area, and fall speed of individual particles are determined. The particles are shape classified according to the scheme presented in our previous work, in which particles sort into 15 different shape groups depending on their shape and morphology. Particle masses of individual ice particles are estimated from measured particle size, cross-sectional area, and fall speed. The selected dataset covers sizes from about 0.1 mm to 3.2 mm, fall speeds from 0.1 m s−1 to 1.6 m s−1, and masses from close to 0.2 μg to 320 μg. In our previous work, the fall speed relationships between particle size and cross-sectional area were studied. In this work, the same dataset is used to determine the particle mass, and consequently, the mass relationships between particle size, cross-sectional area, and fall speed are studied for these 15 shape groups. Furthermore, the mass relationships presented in this study are compared with the previous studies.
An Updated Systematic Review of Human Papillomavirus Genotype Distribution by Cervical Disease Grade in Women Living With Human Immunodeficiency Virus Highlights Limited Findings From Latin America

An updated review of global HPV genotype distribution by cervical disease grade in women living with human immunodeficiency virus revealed limited data from Latin America, a region with high prevalence of HPV and cervical cancer. Supplemental digital content is available in the text. Abstract Cervical cancer is 5 times more likely among women living with human immunodeficiency virus (WHIV), likely due to higher prevalence of human papillomavirus (HPV). Despite evidence of higher rates with multiple HPV genotypes in WHIV, there are no recommendations for triage by HPV genotyping specific to WHIV. In Latin America/Caribbean rates are high and vary significantly. To guide optimization of HPV-based cervical cancer screening among WHIV in Latin America/Caribbean, review of current literature was completed to assess HPV genotype distribution by cervical disease grade in WHIV in this region; and further expanded globally for comparison across regions. A systematic review of the literature from June 2016 to January 2020 revealed 15 studies reporting human papillomavirus (HPV) genotype distribution by cervical disease state (normal, low-grade disease, high-grade disease, and invasive cervical cancer) across different global regions. Across all studies, there were 6928 WHIV from 4 global regions, 3952 of whom were HPV-positive. Three studies from Latin America/Caribbean (LAC) countries were reviewed, with 1 providing enough detail to describe HPV genotypes by cervical disease grade and identified types 31 and 35 in high-grade cervical lesions. Of the studies included, 4 from Africa and Europe/North America each, and 1 from Asia included data that were able to be summarized. Latin America, a region which experiences high rates of HPV, human immunodeficiency virus (HIV), and cervical disease, had few published studies reporting HPV genotypes by cervical disease grade, with 1 reporting individual HPV genotype and specific cervical disease grade. Identifying HPV types associated with CIN2+ in WHIV in this region has the potential to improve screening and treatment for cervical cancer prevention and should be the focus of future research.
Review of Post-Prognostics Decision-Making in Prognostics and Health Management

Mainly, the prognostics and health management (PHM) process is based on three processes: the data acquisition and health assessment process in which sensors signals are acquired and processed, the diagnostic and prognostic process in which the source of failure is detected and the remaining useful life (RUL) is predicted and finally the decisionmaking process that refers to the term management in prognostics and health management. This paper reviews in the literature about the different aspects of decision-making in the context of PHM. The selected papers are subject to content assessment and grouped according to the decision type. Additionally, this paper presents a synthesis of the previous works that helps identify new trends and deficiencies in the decision-making process. The synthesis can guide efforts for future work.
Modified QUIC protocol with congestion control for improved network performance

In the networks, a transport layer is responsible for reliable data with guaranteed Quality of Service. A Modiﬁed-QUIC protocol provides improved throughput and reduced latency of the network. This work proposes a modiﬁcation in handshaking mechanism for QUIC protocol to minimize overhead due to control signals and time required to update the congestion-window size. This modiﬁcation ﬁne-tunes the window update mechanism with the acknowledgment frame, which results in a smooth variation in the congestion-window size. This leads to the control congestion by regulating trafﬁc in the network. In the proposed mechanism, unnecessary time out events are avoided by updating the congestion-window on receipt of the acknowledgment frame. This work has been carried out using two different testbed setups to verify the transport layer and a browser network performance. It has been observed that a Modiﬁed-QUIC protocol is easy to deploy, improves the throughput and data rate by 35% and 3.43%, respectively, over the QUIC protocol. The average fairness index is increased with a ﬁle size and for the long live trafﬁc.
Comparison of laxatives used in CT colonography with full bowel preparation

Purpose. Our study aimed to identify an optimal full-cleanse bowel preparation scheme for patients undergoing CT colonography.Material and methods. The final sample included 118 patients: 81 females (68.6%), with the median age being 75 years (IQR 675-80 years). For bowel preparation 39 (33.1%) patients used PM/Ca, 36 (30.5%) – 2 L PEG + Asc, 19 (16.1%) – 3 L PEG, 24 (20.3%) – 4 L PEG. Otherwise, the preparation did not differ in all four groups. Visual assessment of residual stool, residual fluid, and distension degree was performed using a 4-point Likert scale. The patient’s subjective tolerance assessment was executed according to the survey results using a 5-point Likert scale.Results. There were no statistically significant differences in quality of bowel preparation in all four groups. Mean value of the total residual stool score in groups was 46.2 ± 2.87 for PM/Ca; 46.9 ± 2.34 for 2 L PEG + Asc; 46.5 ± 1.98 for 3 L PEG; 45.9 ± 3.18 for 4 L PEG (p > 0.05). The median of the total residual fluid score in groups was 36 (33–38) for PM/Ca; 36.5 (34–39) for 2 L PEG + Asc; 37 (36–39) for 3 L PEG; 36 (34–40) for 4 L PEG (p > 0.05). Mean value of the total distention degree score in groups was 43 ± 4.34 for PM/Ca; 44.6 ± 3.13 for 2 L PEG + Asc; 44.2 ± 3.98 for 3 L PEG; 43.5 ± 4.9 for 4 L PEG (p > 0.05). There was a statistically significant difference in the patient tolerance total score, depending on the laxative (p = 0.001). The total preparation score was significantly lower for PM/Ca when compared with 2 L PEG + Asc. (p = 0.021), 3 L PEG (p = 0.001), and 4 L PEG (p = 0.043). Conclusion. Use of PM/Ca in CTC preparation lowers the burden of full cleanse exam preparation and can be recommended as a safe laxative choice, including senior age patients.
Stationary ethylene–air edge flames in a wedge-shaped region at low and high strain rates

ABSTRACT Edge flames are a canonical two-dimensional flame structure appearing in lifted jet flames and in the growth and repair of flame holes in nonpremixed turbulent combustion. Computational studies of edge flames with hydrodynamic-coupling at high strains are difficult owing to difficulties defining a stationary state. A wedge-shaped counterflow configuration is here used to provide control over the position of the edge flame, and allowing access to stationary, hydrodynamically-coupled retreating flames (at low and high strains). ethylene–air edge flames are established in the resulting non-uniformly strained counterflow, with combustion modeled using a skeletal reduction of the USC Mech II. The details of the ethylene–air edge flame are discussed, and comparisons are made between stoichiometric, fuel-lean, and fuel-rich compositions. Mixture-fraction-based coordinates local to the flame front are developed and analysed for a range of edge-flame speeds and compositions. A strain-rate parameter is described that admits a speed-strain relationship that is insensitive to the mixture stoichiometry, and a model for retreating flame speeds at high strain rates is discussed.

El presente estudio se lo realizo con la finalidad de identificar a dos tipos de garrapatas, Rhipicephalus microplus y Amblyomma cajennense en vacunos de la parroquia Huambi del canton Sucua, ubicada en la provincia de Morona Santiago. Se utilizaron 367 vacunos elegidos al azar, tomando como dato una muestra significativa de la poblacion total de bovinos existentes en la parroquia, en los cuales se tomo informacion de los niveles de infestacion de garrapatas clasificando a los bovinos por la genetica y por el sexo. El proceso de recoleccion de las garrapatas fue de manera manual, donde el tamano minimo de los ectoparasitos debia ser mayor a 4mm, estos ectoparasitos obtenidos fueron colocados en alcohol al 70% para su sacrificio, conservacion y posterior analisis en frascos debidamente rotulados por animal. En relacion a la genetica presento mucha mas resistencia los Bos Indicus con un 13.6% de animales infestados; los Bos Taurus presentaron el 19,3% de animales y los cruces presentaron una infestacion del 32% de animales; todo esto en relacion a la especie R. microplus; mientras que para la especie A. cajennense los resultados dieron que para B. indicus un 4% de animales infestados, para B. Taurus un 7% de animales y para los cruces dio un total del 14% de vacunos con infestacion ectoparasitaria. En relacion al sexo de los bovinos las hembras fueron mucho mas susceptibles que los machos teniendo el 22,35% de hembras infestadas y un 18,75% de machos; en relacion a la esoecie A. cajennense no hubo diferencias en el grado de infestacion entre machos y hembras.
Fabrication and characterization of poly(ε-caprolactone)/gelatin nanofibrous scaffolds for retinal tissue engineering

ABSTRACT Different ratios of poly(ε-caprolactone) (PCL) and gelatinwere used to fabricate scaffolds for regeneration of retinal pigment epithelium (RPE) layer. Physical and chemical characterizations were performed and the behavior of human RPE cells on the scaffolds was evaluated subsequently. An increase in gelatin content in the scaffold enhanced hydrophilicity, RPE cell attachment, proliferation, and spreading over PCL scaffolds. Granular and cytoplasmic expressions of RPE65 and Cytokeratin 8/18 markers confirmed the presence of RPE cells. It was believed that PCL/gelatin scaffolds could be used as substrates to replace RPE extracellular matrix to facilitate regeneration of RPE layer in retinal diseases. GRAPHICAL ABSTRACT
An Improved PID Controller for the Compliant Constant-Force Actuator Based on BP Neural Network and Smith Predictor

A compliant constant-force actuator based on the cylinder is an important tool for the contact operation of robots. Due to the nonlinearity and time delay of the pneumatic system, the traditional proportional–integral–derivative (PID) method for constant force control does not work so well. In this paper, an improved PID control method combining a backpropagation (BP) neural network and the Smith predictor is proposed. Through MATLAB simulation and experimental validation, the results show that the proposed method can shorten the maximum overshoot and the adjustment time compared with traditional the PID method.
Clinical Patterns and Seasonal Distribution of Urinary Tract Infection Caused by Extended-spectrum Beta-lactamase-producing Bacteria in Children

Introduction: Extended-spectrum β-lactamase-producing Escherichia coli or Klebsiella pneumoniae infections in the pediatric age group are mostly nosocomial infections. This study aimed to investigate the clinical pattern of extended-spectrum β-lactamase positive urinary tract infection and its seasonal distribution. Materials and Methods: We retrospectively reviewed the medical records of pediatric patients with extended-spectrum β-lactamases-positive UTI, who were followed-up in our clinic between June 2015 and June 2020. Results: One hundred-and-ten patients with ESBL-positive UTI and 231 with non-ESBL UTI were enrolled in this study. The rate of male sex in the ESBL group was significantly lower than that in the non-ESBL group (10.9% vs 27.2%, p= 0.001). The patients with ESBL were older than those in the non-ESBL group (81.3 ± 49.0 months vs 56.0 ± 47.2 months, p= 0.001). E. coli was the most isolated bacteria in both groups (68% and 70.5%, respectively). The rate of Klebsiella isolation in urine culture was significantly greater in the ESBL group than in the non-ESBL group (p= 0.04). The seasonal distribution of ESBL-positive patients was as follows: spring (18/16.4%), summer (25/22.7%), autumn (25/22.7%), and winter (42/38.2%). Conclusion: There is a substantially high rate of antibiotic resistance among patients with urinary tract infection in developing countries like Turkey. Moreover, we should be aware of the risk of ESBL-positive UTIs, especially in winter.

Environmental correlates of morphological diversity in Australian geckos

Editor: Brody Sandel Abstract Aim: Climatic variation has long been regarded as a primary source of morphological variation. However, there is mixed support for the adherence of reptiles to ecogeographical hypotheses, such as Bergmann’s rule (body size decreases with temperature) and Allen’s rule (limb length increases with temperature). We quantified body and limb morphology among the diverse Australian gecko fauna (4 families, 30 genera, 226 of the 231 described species) to investigate environmental correlates of morphological variation in this radiation. Location: Australia. Major taxa studied: Geckos (Squamata: Gekkota; the families Gekkonidae, Carphodactylidae, Diplodactylidae and Pygopodidae). Methods: We measured 20 external features of ethanolpreserved museum specimens. We investigated whether principal component axes of morphology were correlated with three key environmental variables, and the microhabitat occupied by each species. Results: Morphology varied greatly among Australian gecko families and genera, although there was a strong phylogenetic signal in morphology. After accounting for phylogeny, morphology was correlated with a species’ microhabitat use. Saxicolous species and species with variable microhabitat requirements (i.e., generalists) had larger body dimensions than terrestrial species. Saxicolous species also had longer proportional forelimbs and hindlimbs than terrestrial species. Main conclusions: Our results highlight the importance of phylogeny and microhabitat use in shaping the morphology of Australian geckos. We find little evidence that Australian geckos adhere to Bergmann’s rule or Allen’s rule, suggesting that these ecogeographical hypotheses provide limited insight into the adaptive potential of lizard species to altered environmental conditions.
Emotional Impact of Dishes versus Wines on Restaurant Diners: From Haute Cuisine Open Innovation

Haute cuisine is emblematic in the world of tourism and is of fundamental importance in the economic and social life in most countries worldwide. Haute cuisine gastronomic experiences play with the senses, involving the diner, thus generating a unique experience for the customer. This empirical study aims to analyze the influence on the consumer of the characteristic stimuli of a high-level gastronomic experience in a restaurant with two Michelin stars. Using neuromarketing biometrics, combined with a qualitative research technique, the objective of this research was to determine the emotional impact of the presentation and tasting of dishes compared to wines and to draw conclusions about each variable in the general experience. The results indicate that the dishes have a greater influence on the level of interest than the wines, and both have a different emotional impact at different moments of the experience due to its duration.
Etiology, Diagnosis, and Treatment of Leukorrhea

The most frequently reported complaints in the urogenital organ system is leukorrhea, also known as fluor albus. Leukorrhea is a discharge secreted from the genital organs, mostly occur in female. Leukorrhea has a significant incidence rate and varies according to many factors such as hormone and infection. Leukorrhea can be physiological in female, but when excess discharge is accompanied by other characteristics, the leukorrhea is considered pathological. This genital discharge also occurs in male for pathological reasons, mainly caused by infection. Several pathogenic infections, whether transmitted through secual contact or not, are the etiology of complaints of leukorrhea. Some specific pathogens will cause different symptoms in the two sex groups. To make a diagnosis, it is important for the examiner to carry out a detailed and coherent history, especially regarding sexual contact and a history of risky sexual behavior. Although some infections are asymptomatic, complications may occur if infections are not treated properly as early as possible. The management of leukorrhea is based on an examination and treatment algorithm with syndromic approach.
The Seasonality of In‐Stream Nutrient Concentrations and Uptake in Arctic Headwater Streams in the Northern Foothills of Alaska's Brooks Range

Over the past 30 plus years, the Arctic has warmed at a rate of 0.6°C per decade. This has resulted in considerable permafrost thaw and alterations of hydrological and biogeochemical processes. Coincident with these changes, recent studies document increases in annual fluxes of inorganic nutrients in larger Arctic rivers. Changing nutrient fluxes in Arctic rivers have been largely attributed to warming‐induced active layer expansion and newly exposed subsurface source areas. However, the ability of Arctic headwater streams to modulate inorganic nutrient patterns manifested in larger rivers remains unresolved. We evaluated environmental conditions, stream ecosystem metabolism, and nutrient uptake in three headwater streams of the Alaskan Arctic to quantify patterns of retention of inorganic nitrogen (N) and phosphorous (P). We observed elevated ambient nitrate‐N (NO3‐N) concentrations in late summer/early fall in two of three experimental stream reaches. We observed detectable increases in uptake as a result of nutrient addition in 88% of PO4‐P additions (n = 25), 38% of NH4‐N additions (n = 24), and 24% of NO3‐N additions (n = 25). We observed statistically significant relationships between NH4‐N uptake and ecosystem respiration, and PO4‐P uptake and gross primary productivity. Although these headwater streams demonstrate ability to control downstream transport of PO4‐P, we observed little evidence the same holds for dissolved inorganic N. Consequently, our results suggest that continued increases in terrestrial to aquatic N transfer in Arctic headwater landscapes are likely to be evident in larger Arctic rivers, in‐network lakes, and coastal environments.
Cyber Place Management and Crime Prevention: The Effectiveness of Cybersecurity Awareness Training Against Phishing Attacks

Criminologists and crime prevention practitioners recognize the importance of geographical places to crime activities and the role that place managers might play in effectively preventing crime. Indeed, over the past several decades, a large body of work has highlighted the tendency for crime to concentrate across an assortment of geographic areas, where place management tends to be absent or weak. Nevertheless, there has been a paucity of research evaluating place management strategies and cybercrime within the virtual domain. The purpose of this study was to investigate the effectiveness of place management techniques on reducing cybercrime incidents in an online setting. Using data derived from the information technology division of a large urban research university in the United States, this study evaluated the impact of an anti-phishing training program delivered to employees that sought to increase awareness and understanding of methods to better protect their “virtual places” from cybercrimes. Findings are discussed within the context of the broader crime and place literature.
