Communicating With Breast Imaging Patients During the COVID-19 Pandemic: Impact on Patient Care and Physician Wellness

Abstract Objective Assess the impact of COVID-19 on patient-breast radiologist interactions and evaluate the relationship between safety measure–constrained communication and physician wellbeing. Methods A 41-question survey on the perceived effect of COVID-19 on patient care was distributed from June 2020 to September 2020 to members of the Society of Breast Imaging and the National Consortium of Breast Centers. Non-radiologists and international members were excluded. Anxiety and psychological distress scores were calculated. A multivariable logistic model was used to identify demographic and mental health factors associated with responses. Results Five hundred twenty-five surveys met inclusion criteria (23% response rate). Diminished ability to fulfill patients’ emotional needs was reported by 46% (221/479), a response associated with younger age (OR, 0.8 per decade; P < 0.01), higher anxiety (OR, 2.3; P < 0.01), and higher psychological distress (OR, 2.2; P = 0.04). Personal protective equipment made patient communication more difficult for 88% (422/478), a response associated with younger age (OR, 0.8 per decade; P = 0.008), female gender (OR, 1.9; P < 0.01), and greater anxiety (OR, 2.6; P = 0.001). The inability to provide the same level of care as prior to COVID-19 was reported by 37% (177/481) and was associated with greater anxiety (OR, 3.4; P < 0.001) and psychological distress (OR, 1.7; P = 0.03). Conclusion The majority of breast radiologists reported that COVID-19 has had a negative impact on patient care. This perception was more likely among younger radiologists and those with higher levels of anxiety and psychological distress.
Anomaly Detection Using Power Signature of Consumer Electrical Devices

Abstract The use of the smart grid for developing intelligent applications is a current trend of great importance. One advantage lies in the possibility of direct monitoring of all devices connected to the electrical network in order to prevent possible malfunctions. Therefore, this paper proposes a method for an automatic detection of the malfunctioning of low-intelligence consumer electrical devices. Malfunctioning means any deviation of a household devi ce from its normal operating schedule. The method is based on a comparison technique, consisting in the correlation between the current power signature of a device and an ideal signature (the standard signature provided by the manufacturer). The first step of this method is to achieve a simplified form of power signature which keeps all the original features. Further, the signal is segmented based on the data provided by an event detection algorithm (values of the first derivatives) and each resulting component is approximated using a regression function. The final step consists of an analysis based on the correlation between the computed regression coefficients and the coefficients of the standard signal. Following this analysis all the differences are classified as a malfunctioning of the analyzed device. Index Terms Feature extraction, Pattern matching, Signal analysis, Signal processing.
A Study on Lower Limb Asymmetries in Parkinson’s Disease during Gait Assessed through Kinematic-Derived Parameters

Unilaterality of motor symptoms is a distinctive feature of Parkinson’s Disease (PD) and represents an important co-factor involved in motor deficits and limitations of functional abilities including postural instability and asymmetrical gait. In recent times, an increasing number of studies focused on the characterization of such alterations, which have been associated with increased metabolic cost and risk of falls and may severely compromise their quality of life. Although a large number of studies investigated the gait alterations in people with PD (pwPD), few focused on kinematic parameters and even less investigated interlimb asymmetry under a kinematic point of view. This retrospective study aimed to characterize such aspects in a cohort of 61 pwPD (aged 68.9 ± 9.3 years) and 47 unaffected individuals age- and sex-matched (66.0 ± 8.3 years), by means of computerized 3D gait analysis performed using an optical motion-capture system. The angular trends at hip, knee and ankle joints of pwPD during the gait cycle were extracted and compared with those of unaffected individuals on a point-by-point basis. Interlimb asymmetry was assessed using angle–angle diagrams (cyclograms); in particular, we analyzed area, orientation, trend symmetry and range offset. The results showed that pwPD are characterized by a modified gait pattern particularly at the terminal stance/early swing phase of the gait cycle. Significant alterations of interlimb coordination were detected at the ankle joint (cyclogram orientation and trend symmetry) and at the hip joint (range offset). Such findings might be useful in clinical routine to characterize asymmetry during gait and thus support physicians in the early diagnosis and in the evaluation of the disease progression.
Hybrid Teaching in Schools: Pedagogical Innovation and Professional Well-Being in a Time of Pandemic

At a time where education seems submerged by crisis, some teachers manage to be resilient in order to innovate to adapt and meet educational expectations. This research’s objectives are twofold: 1) to report on their pedagogical innovations and 2) to describe their professional well-being during this unprecedented time. A multi-case study with 20 teachers working in Quebec, in primary and secondary schools, made it possible to present 1) the guidelines teachers followed which directly affected their work context and modulated their professional task, 2) the practices specific to planning, teaching and evaluating, and 3) the evolution of professional well-being, shown alongside with the findings.
CMOS Circuits for High-Density neural Interfaces and Nanowire Sensor Arrays

8 Paolo Livi nanowires for high-temporal-resolution experiments and parallel sensor experiments (results from pH and KCl concentration sweeps are presented); (2) high speed measurements showing how the CMOS chip can enhance the performance of the nanowire sensor by compensating its limitations as a consequence of hysteresis. In order to obtain a more compact system, different methods of monolithically integrating NW sensor arrays on a CMOS chip were investigated. This approach also eliminates the noise introduced by the interconnections in comparison to the use of two separate chips (the NW array and the CMOS readout). The successful integration of a gold NW array, as well as of a SiNW array on the CMOS chip was demonstrated. Both systems have been tested electrically. Moreover, a PDMS-based packaging system including a microfluidic channel was built, which enabled sensing experiments in the liquid phase on top of the CMOS chip: KCl adsorption on gold NWs and pH measurements with the SiNWs were performed. Furthermore, the capability of the SiNWs to detect proteins at low concentrations was demonstrated by measuring the human cardiac marker troponin T (cTnT) down to 1nM. The use of double-gate (DG) FinFETs as biosensing devices has been investigated. Specifically, the work in this thesis aimed at demonstrating how FinFETs can be used to build simple circuits that allow for an enhancement of the sensing event readout. Examples of so-called sensing circuits based on FinFETs and incorporating both the sensor and the readout have been proposed and successfully validated with simulations.
U-shaped frequency selective surfaces for single- and dual-band applications together with absorber and sensor configurations

In this study, the frequency selective surface (FSS), absorbance and sensing applications of new unit cells comprised of single, double and quad U-shaped metallic elements are numerically and experimentally investigated. The numerical results are realised by using finite integration technique-based electromagnetic simulation software, CST Microwave Studio. Experimental results are obtained by means of Agilent N5234A PNA-L vector network analyser. The simulated and measured results of U-shaped FSSs are carried out by using two different ways; periodic unit cell and waveguide boundary conditions. The single and quad U-shaped FSS elements show a single band-stop filter property, whereas the double U-shaped FSS shows a dual-frequency band-stop filter behaviour. Absorber and sensor applications of the proposed U-shaped FSSs are illustrated both numerically and experimentally. The three types of U-shaped FSS structures show a narrowband absorbance which has potential in biomedical and sensing applications. Single and dual absorber characteristics are observed with a 90% absorbance. For the sensor configuration, 800 MHz bandwidth is obtained for sensing different materials showing that it is possible to realise different microwave sensor studies in industries of food and agriculture. Simulated and measured results are compared for FSS, absorber and sensor configurations, and the results show a good agreement with each other.
Injuries in Competitive Austrian Gymnasts

Background: Competitive gymnastics is a physically demanding sport that requires flexibility, coordination, endurance and strength. The biomechanics of the sport also result in a specific injury profile. Methods: A total of 30 gymnasts from the Austrian national team (21.9±3.9 years) and 25 competitive gymnasts not affiliated with the national team (22.8±6.4 years) provided information on their injuries of a 3-year period (2018-2020) via an online survey. The injury rate per 1000 hours of training was calculated and injuries were stratified by severity, injured body structure and the localization of the injury. Mann Whitney U and Chi-square tests were used to examine differences between national team and non-national team gymnasts. Results: A total of 64 injuries were reported, which resulted in 0.4 injuries per 1000 hours of training. There was no difference in injury rate per training hours; national team members, however, reported significantly more injuries per person compared to their non-national team peers (1.4±1.1 vs. 0.8±1.0; p=0,04). The most common tissue affected by injuries were tendons and ligaments (59%) while muscle injuries were the least common injuries (11%). Almost half of the injuries (47%) affected the lower extremities, with ankle injuries being the most common ones. Roughly 80% of injuries were considered minor to moderate and could be treated via outpatient care. Across the different disciplines of gymnastics most injuries were reported during floor routines (36%) followed by vault (16%). Conclusion: Injury risk was directly associated with training volume. Severe injuries, however, were rare even in highly competitive gymnasts.
Experimental characterization of vibro-acoustic properties of an aircraft fuselage

Modern turbo-prop engines have been identified as an efficient alternative to jet engines for the propulsion of next generation short range aircraft. However, the benefit in operating efficiency comes along with disadvantages related to engine noise and noise transmission into the aircraft cabin. Numerical models used for response analysis often show significant deviations in the medium frequency range up to 500 Hz. Model validation based on experimental modal data is often not possible due to the high modal density that aircraft fuselage structures exhibit in this frequency range. A method is presented that provides a meaningful correlation of the results of vibration tests on aircraft fuselage structures with corresponding numerical predictions. The correlation criterion used is inspired by statistical energy analysis and is based on kinetic energies integrated over frequency bands and spatially integrated over surface areas of the fuselage structure. The objective is to indicate frequency bands where the finite element model needs to be adjusted to better match with experimental observations up to 500 Hz and to locate the areas where these adjustments should be applied. The application of the kinetic energy correlation criterion comes along with several requirements on the test equipment, test installation and testing procedures. An effort has been spent to extent well defined testing procedures stemming from aircraft ground vibration testing into the medium frequency range. As a result, a test method is presented that has been applied in a test campaign on a full-scale aircraft fuselage structure to validate the proposed correlation criterion based on kinetic energies.
Effect of Nitrogen and Phosphorus Fertilizers on Nutrient Content and Uptake of High Quality Protein Maize (Zea mays L.) to under South Saurashtra Agroclimatic Zone of Gujarat

An experiment was conducted to assess the “effect of nitrogen and phosphorus fertilizers on nutrient content and uptake of high quality protein maize (Zea mays L.) to under South Saurashtra agroclimatic zone of Gujarat” during summer, 2016 at the department of agronomy, college of agriculture, JAU, Junagadh. The experiment comprising of total twelve treatment combinations consisting four levels of nitrogen (Control, 90 kg N ha-1, 120 kg N ha-1, 150 kg N ha-1) and three levels of phosphorus (Control, 45 kg P2O5 ha-1, 60 kg P2O5 ha-1) laid out in Factorial Randomized Block Design replicated thrice. The results revealed that application of 150 kg N/ha significantly higher nitrogen, phosphorus and potassium content and uptake of grains and straw over control and 90 kg N/ha, while at par with 120 kg N/ha. Result showed that application of 60 kg P2O5 /ha significantly higher nitrogen, phosphorus and potassium content and uptake of grains and straw, being remained at par with 45 kg P2O5 /ha over control.
Nutritional Quality and Safety of the Spirulina Dietary Supplements Sold on the Slovenian Market

The microalgae Spirulina may be a popular dietary supplement rich in essential nutrients and vitamins, but oversight of the supplement industry, in general, remains limited, and increasing incidents of adulteration, misbranding, and undeclared ingredients together with misleading claims create potential risks. In response, this study characterized the elemental, amino acid and fatty acid content of commercially available Spirulina supplements in Slovenia using EDXRF, ICP-MS and GC-MS and compared the results with their nutritional declaration. The gathered data confirm that Spirulina supplements are a good source of calcium (0.15 to 29.5% of RDA), phosphorous (3.36–26.7% of RDA), potassium (0.5 to 7.69% of RDA) and selenium (0.01 to 38.6% of RDA) when consumed within recommended amounts. However, although iron contents were relatively high (7.64 to 316% of RDA), the actual bioavailability of iron was much lower since it was mainly present as the ferric cation. This study also confirms that pure Spirulina supplements are a good source of essential and non-essential amino acids, and ω-6 but not ω-3 polyunsaturated fatty acids. The presence of additives resulted in significant variation in nutrient content and, in some instances, lower product quality. Moreover, a high proportion (86.7%) of inappropriate declarations regarding the elemental content was observed. Overall, the study conclusions underline the need for a stricter control system for Spirulina-based supplements.
Functional Analysis of Fracture Patella Managed with Tension Band Wiring

Background: Fracture patella accounts for around 1% of all skeletal fractures. It is basically of 2 types: displaced fracture and un displaced fracture. It mainly occurs due to direct blows to the knee joint such as car accidents, injuries, or direct falls on the ground with bent knees. Management of these fractures varies from cylindrical cast application to surgical management for displaced fractures. This study focuses on the functional evaluation of fracture patella managed with tension band wiring. Materials and Methods: 17 patients with displaced transverse patella fracture managed with tension band wiring were included in the study. An interventional study was performed in AVBRH hospital Wardha between 2017-2019. Operated patients were followed up at one month, two months, and three months for functional assessment. On every follow-up, x-ray was taken to assess the union and implant positioning. Observations and Results: 41.47 were the mean age (in years) of patients participating in the study. In the study, 17 patients participated, 13 were males (76.47%) and 4 were females (23.53%). Comminuted and oblique fractures were excluded from the study. Out of 17 patients at final follow up, 70.58% patients had excellent results, 29.42 percent had good results, and no patient had a poor functional outcome. Conclusion: Tension band wiring of fracture patella yields better fun outcomes outcome and an inexpensive method of managing fractured patella. Early knee mobilization and knee range of motion exercises should be started to avoid quadriceps muscle wasting.
The Impact of the COVID-19 Pandemic on Women’s Adjustment Following Pregnancy Loss

Abstract There are a variety of constraints to accessing social support following pregnancy loss that can negatively impact women. Being able to seek and receive needed social support following pregnancy loss may be further complicated by the ongoing COVID-19 pandemic. The current study explored the experiences and impact of the COVID-19 pandemic on women who have experienced miscarriage or stillbirth. Results showed that the pandemic exacerbated women’s feelings of grief, trauma, depression and anxiety. These findings indicate that addressing the mental health needs of women who have experienced pregnancy loss during the pandemic should be evaluated and addressed.
Incidence of Candidemia Is Higher in COVID-19 versus Non-COVID-19 Patients, but Not Driven by Intrahospital Transmission

There is scarce information on the actual incidence of candidemia in COVID-19 patients. In addition, comparative studies of candidemia episodes in COVID-19 and non-COVID-19 patients are heterogeneous. Here, we assessed the real incidence, epidemiology, and etiology of candidemia in COVID-19 patients, and compared them with those without COVID-19 (2020 vs. 2019 and 2020, respectively). We also genotyped all C. albicans, C. parapsilosis, and C. tropicalis isolates (n = 88), causing candidemia in both groups, providing for the first time a genotypic characterization of isolates gathered in patients with either COVID-19 or non-COVID-19. Incidence of candidemia was higher in patients with COVID-19 than non-COVID-19 (4.73 vs. 0.85 per 1000 admissions; 3.22 vs. 1.14 per 10,000 days of stay). No substantial intergroup differences were found, including mortality. Genotyping proved the presence of a low number of patients involved in clusters, allowing us to rule out rampant patient-to-patient Candida transmission. The four patients, involved in two clusters, had catheter-related candidemia diagnosed in the first COVID-19 wave, which demonstrates breaches in catheter management policies occurring in such an overwhelming situation. In conclusion, the incidence of candidemia in patients with COVID-19 is significantly higher than in those without COVID-19. However, genotyping shows that this increase is not due to uncontrolled intrahospital transmission.
Improved management of farm dams increases vegetation cover, water quality, and macroinvertebrate biodiversity

Abstract In many farming landscapes, aquatic features, such as wetlands, creeks, and dams, provide water for stock and irrigation, while also acting as habitat for a range of plants and animals. Indeed, some species threatened by land‐use change may otherwise be considerably rarer—or even suffer extinction—in the absence of these habitats. Therefore, a critical issue for the maintenance of biodiversity in agricultural landscapes is the extent to which the management of aquatic systems can promote the integration of agricultural production and biodiversity conservation. We completed a cross‐sectional study in southern New South Wales (southeastern Australia) to quantify the efficacy of two concurrently implemented management practices—partial revegetation and control of livestock grazing—aimed at enhancing the vegetation structure, biodiversity value, and water quality of farm dams. We found that excluding livestock for even short periods resulted in increased vegetation cover. Relative to unenhanced dams (such as those that remained unfenced), those that had been enhanced for several years were characterized by reduced levels of turbidity, nutrients, and fecal contamination. Enhanced dams also supported increased richness and abundance of macroinvertebrates. In contrast, unenhanced control dams tended to have high abundance of a few macroinvertebrate taxa. Notably, differences remained between the macroinvertebrate assemblages of enhanced dams and nearby “natural” waterbodies that we monitored as reference sites. While the biodiversity value of semilotic, natural waterbodies in the region cannot be replicated by artificial lentic systems, we consider the extensive system of farm dams in the region to represent a novel ecosystem that may nonetheless support some native macroinvertebrates. Our results show that management interventions such as fencing and grazing control can improve water quality in farm dams, improve vegetation structure around farm dams, and support greater abundance and diversity of aquatic macroinvertebrates.
Parametric Modeling for Advanced A rchitecture

Computer simulation of evolutionary processes is already well established technique for the study of environmental, biological and economic dynamics. Use of algorithms for generation of virtual entities that will develop its functional and formal properties within the non-linear process of adaptation of complex system is a foundation for new point of view in understanding architecture and urban environment. This paper describes parametric approach in architectural design through elaboration of shift in paradigms in architecture that has brought to the idea of use of parametric modeling with emphasis on two different groups of parametric software and presents the possibilities of generative algorithms in modeling architectural form and development of cities and urban design.
Manner of Death Impacts the Death Effect in Literary Evaluation

The existence of a death effect—that the value of a creative work tends to increase after the creator has died—in literary evaluation was demonstrated. To replicate and extend previous findings, (N = 408) university students were asked to imagine being an art collector potentially interested in purchasing a short story. The status of the author varied from still being alive to having died from a car accident, suicide, or heart attack. Consistent with earlier work, students, when informed that the author was dead, offered to pay more money (81% more, on average) to purchase the story relative to students informed that the author was alive. Unique to this investigation, students offered the most money when told that the author died from a car accident. Priming students about death and dying boosted valuations. Unlike earlier work, subjective impressions about the author and the story were not affected by these manipulations. Mortality awareness and the relatability of the manner of death enhanced the desire for a perceived-to-be scarce product, in this case a creative literary work from a dead author.
