Published: June 2022

Purpose: This study aimed to investigate the relationship between dielectric properties (permittivity and conductivity), thermoacoustic signals (TAS) and temperature of liver tissues at 3.0 GHz.Materials and Methods: An open-ended coaxial probe was used to measure the dielectric properties of fresh porcine liver tissues in vitro, and a thermoacoustic imaging (TAI) system was used to collect the TAS. Porcine liver tissues were placed on a heating platform, and the dielectric properties measuring probe and temperature sensor were inserted into the liver tissues separated by 1.5 cm. First, the liver tissues were gradually heated by a heating platform from room temperature (30°C) to 60°C, and the dielectric properties and TAS were measured as the temperature increased approximately every 1°C. Second, after the temperature of the porcine liver tissue reached 60°C, the heating platform was turned off to naturally cool the porcine liver tissue to room temperature. During the process, the dielectric properties and TAS were also measured as the temperature decreased every 1°C. Finally, the changes in the dielectric properties and TAS of the liver tissues with temperature at 3.0 GHz frequency were analyzed.Results: During the process of heating the tissues up to 60°C, the conductivity of the porcine liver tissues decreased while the permittivity and TAS of the porcine liver tissues increased, and the relationships were nonlinearly correlated. Meanwhile, during the cooling process, the conductivity of the porcine liver tissues increased, while the permittivity and TAS decreased, and the relationships were also nonlinearly correlated.Conclusion: The dielectric properties and TAS of porcine liver tissue changed significantly with temperature, which makes it possible to differentiate the safety margin during liver thermal ablation with thermoacoustic imaging (TAI). While the relationship between temperature, dielectric properties and TAS needs to be further investigated, TAI has the potential to be utilized for safety margin screening during thermal ablation.

BackgroundStory recall (SR) tests have shown variable sensitivity to rate of cognitive decline in individuals with Alzheimer’s disease (AD) biomarkers. Although SR tasks are typically scored by obtaining a sum of items recalled, item-level analyses may provide additional sensitivity to change and AD processes. Here, we examined the difficulty and discrimination indices of each item from the Logical Memory (LM) SR task, and determined if these metrics differed by recall conditions, story version (A vs. B), lexical categories, serial position, and amyloid status.Methodsn = 1,141 participants from the Wisconsin Registry for Alzheimer’s Prevention longitudinal study who had item-level data were included in these analyses, as well as a subset of n = 338 who also had amyloid positron emission tomography (PET) imaging. LM data were categorized into four lexical categories (proper names, verbs, numbers, and “other”), and by serial position (primacy, middle, and recency). We calculated difficulty and discriminability/memorability by item, category, and serial position and ran separate repeated measures ANOVAs for each recall condition, lexical category, and serial position. For the subset with amyloid imaging, we used a two-sample t-test to examine whether amyloid positive (Aβ+) and amyloid negative (Aβ−) groups differed in difficulty or discrimination for the same summary metrics.ResultsIn the larger sample, items were more difficult (less memorable) in the delayed recall condition across both story A and story B. Item discrimination was higher at delayed than immediate recall, and proper names had better discrimination than any of the other lexical categories or serial position groups. In the subsample with amyloid PET imaging, proper names were more difficult for Aβ+ than Aβ−; items in the verb and “other” lexical categories and all serial positions from delayed recall were more discriminate for the Aβ+ group compared to the Aβ− group.ConclusionThis study provides empirical evidence that both LM stories are effective at discriminating ability levels and amyloid status, and that individual items vary in difficulty and discrimination by amyloid status, while total scores do not. These results can be informative for the future development of sensitive tasks or composite scores for early detection of cognitive decline.

BackgroundResting-state EEG microstate and omega complexity analyses have been widely used to explore deviant brain function in various neuropsychiatric disorders. This study aimed to investigate the features of microstate dynamics and spatial complexity in patients with late-life schizophrenia (LLS).MethodMicrostate and omega complexity analyses were performed on resting-state EEG data from 39 in patients with LLS and compared with 40 elderly normal controls (NCs).ResultThe duration of microstate classes A and D were significantly higher in patients with LLS compared with NCs. The occurrence of microstate classes A, B, and C was significantly lower in patients with LLS compared with NCs. LLS patients have a lower time coverage of microstate class A and a higher time coverage of class D than NCs. Transition probabilities from microstate class A to B and from class A to C were significantly lower in patients with LLS compared with NCs. Transition probabilities between microstate class B and D were significantly higher in patients with LLS compared with NCs. Global omega complexity and anterior omega complexity were significantly higher in patients with LLS compared with NCs.ConclusionThis study revealed an altered pattern of microstate dynamics and omega complexity in patients with LLS. This may reflect the disturbed neural basis underlying LLS and enhance the understanding of the pathophysiology of LLS.

Published: June 2022

ObjectivesAttention deficit hyperactivity disorder (ADHD) frequently co-occurs with other neurodevelopmental diagnoses, such as autism spectrum disorder (autism), which can make clinical decision making around symptom management challenging for clinicians. There is a paucity of research examining pharmacotherapeutic management of children who have ADHD with co-occurring diagnoses. We aimed to report on the co-occurring diagnoses and symptom profile of children, and report on medication use, stratified by ADHD, autism and ADHD + autism diagnoses.Methods and MaterialsCaregivers of 505 children (2–18 years) with ADHD (n = 239), autism (n = 117), and co-occurring ADHD + autism (n = 149) completed a questionnaire on current medication use and clinical rating scales about their child's symptoms, as part of a broader project investigating diagnosis and management of symptoms in children with ADHD or autism.ResultsThe parents of the ADHD group reported a higher proportion of their children had learning disorders (17.15%) and speech and language disorders (4.60%) compared to the parents of the autism and ADHD + autism groups. Parents of the ADHD + autism group reported higher proportions of intellectual disability (5.37%), oppositional defiant disorder (20.13%), anxiety (38.93%), depression (6.71%) and genetic conditions (3.36%) in their children, in comparison to the parents of the ADHD and autism groups. Children with ADHD were reported to be taking a higher proportion of psychotropic medication (90%), followed by ADHD + autism (86%) and autism (39%). The parents of children with ADHD + autism reported a higher proportion of non-stimulant ADHD medication (25.5%), antipsychotic (18.79%), antidepressant (22.15%) and melatonin (31.54%) use by their children, compared to the parents of the ADHD and autism groups.ConclusionsA similar proportion of children with ADHD + autism and ADHD were reported to be taking medication. However, the types of medication taken were different, as expected with reported co-occurring diagnoses. The complexity of symptoms and diagnoses in ADHD + autism warrants targeted research to optimize management and therapeutic outcomes.

Published: June 2022

Background:There were few studies to report whether drinking water sources and habits affected health outcomes. Therefore, this study aimed to examine how boiled water and lifespan water sources affected the risks of cardiovascular disease (CVD) and all-cause mortality in the elderly.MethodsThis study was a 20-year cohort study. All participants aged ≥60 years were eligible. Exposures of interest included lifespan drinking water sources and habits, which were collected using a validated questionnaire. Drinking water sources included wells, surface water, spring, and tap water in childhood, around the age of 60 years, and at present. Drinking habits included boiled and un-boiled water. The main end events included CVD and all-cause mortality.ResultsThere were 33,467 participants in this study. Compared to tap water, drinking well and surface water around the age of 60 years were associated with a higher risk of all-cause mortality (HR: 1.092, 95% CI: 1.051–1.134, P &lt; 0.001; and HR: 1.136, 95% CI: 1.081–1.194, P &lt; 0.001, respectively). However, only drinking spring around aged 60 years and drinking well at present were associated with a lower CVD mortality (HR: 0.651, 95% CI: 0.452–0.939, P = 0.022; and HR: 0.757, 95% CI: 0.665–0.863, P &lt; 0.001, respectively). Boiled water was not associated with mortality.ConclusionsDrinking water from well and surface water around the age of 60 years were associated with increased all-cause mortality. Drinking water from spring around the age of 60 years and well at present was associated with a decreased CVD mortality. However, boiled water was not associated with mortality.

IntroductionTelemedicine has had a slow integration into surgical subspecialties like urology. Little data exists on its effect on urologic patient-provider rapport nor long term clinical outcomes. The purpose of this study was to assess the feasibility and parent-reported experience with telemedicine visits in a tertiary pediatric urology practice during the COVID-19 pandemic.MethodsParents/guardians of pediatric urology patients who were seen via telemedicine between March 12th - October 30th, 2020, at Children’s Hospital Colorado main campus or a satellite campus were contacted within 1 week of their child’s visit and invited to take a telephone survey. A total of 4 yes/no questions and an open-ended question was asked to explore domains of the drawbacks and benefits to telemedicine. Categorical responses and associations between parent demographics and telehealth satisfaction were analyzed with descriptive statistics. Open-ended questions were analyzed using a team-based content analysis approach.ResultsResponse rate was 76.7% (376/490). Median patient age was 4 years. 60.9% (229/376) patients were male, and 39.1% (147/376) patients female. 96.5% of parents felt that all their questions were answered by the end of their appointment. 97.8% of parents felt comfortable using telemedicine for future appointments. Patient sex, age, provider type, insurance type, clinic site, distance from clinic site, and visit diagnosis had no significant impact on survey response. Based on open-ended responses, five general themes emerged: issues with accessing technology, time saving logistics, challenging clinical interactions, a positive overall experience, and parents having about a 50/50 split in preference for telemedicine or in person visits. Multiple parents expressed discomfort with a genital exam via telemedicine.ConclusionsOverall, parents found telemedicine to be an acceptable alternative to in-person visits and demonstrated a willingness to continue to use it in the future. Patient diagnosis and insurance type had no effect on parent response. Parents noted that pediatric urology offers unique challenges due to its personal and sensitive treatment, including the need to evaluate the genitalia. As the role of telemedicine continues to expand, consideration of these challenges is needed to ensure that pediatric urology patients and their parents are comfortable with this approach.

IntroductionPara badminton entered the Paralympic world for the first time with the 2021 Paralympic Games in Tokyo. The particularity of this sport lies in the handling of the wheelchair and the racket simultaneously. To the best of our knowledge, and considering the youthfulness of this sport, it appears that no study has looked at the impact of the badminton racket on the kinetic and spatiotemporal parameters. Therefore, the aim of our study was to investigate the impact of the badminton racket on the amplitude of kinetic and spatiotemporal parameters of wheelchair propulsion, considered as propulsion effectiveness and risk of injury criteria. We hypothesized that holding a badminton racket while propelling the wheelchair modifies the kinetics and temporal parameters of the athlete's propulsion due to the difficulty to hold the handrim, therefore decreasing propulsion effectiveness and increasing risk of injury.Materials and MethodsFor six 90-min sessions, 16 able-bodied individuals were introduced to badminton. No injuries hindered their propulsion. They had to propel with and without a racket held on the dominant side along a 20 m straight line at a constant velocity of 5 km/h. They all used the same sports wheelchair equipped with two instrumented wheels (SmartWheel).ResultsParticipants increased their maximal total force and force rate of rise but decreased their fraction of effective force with their dominant hand compared to the non-dominant hand when using a racket. In addition, they decreased their fraction of effective force, push time, cycle time, and push angle, and increased their maximal propulsive moment, maximal total force, and force rate of rise when comparing the same dominant hand with and without the racket.DiscussionUsing a badminton racket modifies the athlete's force application in a way that is generally related to lower propulsion effectiveness and a higher risk for injury. Indeed, it seems that propulsion with a racket prevents from correctly grabbing the handrim.
Effect of 17β-Estradiol on Growth and Biosynthesis of Microalgae Scenedesmus quadricauda (CPCC-158) and Duckweed Lemna minor (CPCC-490) Grown in Three Different Media

Published: June 2022

As fish farm wastewaters have detectable levels of fish hormones, such as 17β-estradiol (E2), an understanding of the influence of fish steroids on algal (Scenedesmus quadricauda) and duckweed (Lemna minor) physiology is relevant to the potential use of fishery wastewaters for microalgae and plant biomass production. The study was conducted using three types of media: Bold Basal Medium (BBM), natural fishery wastewater (FWW), and reconstituted fishery wastewater (RFWW) with the nutrient composition adjusted to mimic FWW. During the experiment, the media were aerated and changes in the pH and conductivity of the water were closely monitored. E2 promoted the growth of S. quadricauda and L. minor, with significant accumulation of high-value biomolecules at very low steroid concentrations. However, clear differences in growth performance were observed in both test cultures, S. quadricauda and L. minor, grown in different media, and the most effective hormone concentrations were evidently different for the algae and the plant.

Published: June 2022

Background: The incidence of gastrointestinal bleeding in patients with severe burns can reach up to 10%.Objective: Evaluation of the risk factors for gastrointestinal bleeding and of the effectiveness of stress ulcer prophylaxis in patients with severe burns receiving proton pump inhibitors.Material and methods: The study included the results of treatment of 270 patients with burns more than 10% of total body surface area (TBSA), in whom 13 potential risk factors for gastrointestinal bleeding were studied. All patients received omeprazole therapy with 40 mg № 1 intravenous or 20 mg № 2 orally. The data obtained were processed in Microsoft Office Excel 2007 and IBM SPSS 20.0.Results: Significant risk factors for gastrointestinal bleeding were hypotension requiring treatment with vasopressors (dopamine ≥ 10 μg/kg/min or norepinephrine ≥ 0.5 μg/kg/min) for 2 or more days (χ2 = 5.126; p = 0.024) and full thickness burns with more than 50% of total body surface area (χ2 = 7.031; p = 0.008). The incidence of gastrointestinal bleeding was 4%. These bleedings were hemodynamically insignificant; in all cases, acute ulcers were the cause for them. There were no recurrences of bleeding and no repeated endoscopy or surgical treatment was required. The developed bleeding did not have a significant effect on mortality.Conclusion: Using proton pump inhibitors minimizes the frequency and intensity of gastrointestinal bleeding and also prevents lifethreatening complications during their development. More complex prevention of stress ulceration is necessary for patients with full thickness burns more than 50% of TBSA which develop hypotension requiring long‑term vasopressor therapy.
Cordilheira de amora II: detritos de infância Guarani-Kaiowá
Authors: Soeiro Bárbara 
Published: June 2022

Cordilheira de amora II é um documentário/curta-metragem produzido pela cineasta Jamille Fortunato, no ano de 2015. Gravado na aldeia Amambai, no Mato Grosso do Sul, o curta acompanha a garotinha Guarani Kaiowá Cariane Martins, de nove anos de idade. Em meio às ruínas de tijolos, barro seco, madeira velha e eletrodomésticos abandonados, Cariane cria a sua realidade imaginária. A partir de objetos descartáveis — detritos da existência adulta — faz do seu quintal um experimento do mundo. Tomando como ponto de partida a narrativa e a voz da criança, interessa-nos neste artigo debruçarmo-nos sobre o saber infantil simultaneamente associado ao saber indígena, ambos saberes tidos como “menores” frente a um sistema-mundo moderno que privilegia o conhecimento europeu — e, evidentemente, o conhecimento adulto —, alçando-o ao falso patamar de conhecimento universal, pretensamente capaz de abarcar toda a história e subjetividade dos povos. A fantasia aparece aqui não mais como antítese da objetividade, racionalidade, exatidão; surge, antes, como vetor potencial do que chamamos uma “poética infantil-indígena”, combativa, em sua própria singularidade, na resposta contra as amarras de uma “colonização da imaginação”.

Published: June 2022

CEL NAUKOWY: Celem opracowania jest przedstawienie uwarunkowań kontekstowych kazań i homilii w aspekcie kształtowania duchowości dziecka.
PROBLEM I METODY BADAWCZE: Główny problem badawczy dotyczy odpowiedzi na pytanie, na ile kontekst wpływa na skuteczność komunikacyjną działań językowych podejmowanych podczas wystąpień związanych z działalnością duszpasterską. Wykorzystano metodę analizy pragmalingwistycznej, ze szczególnym uwzględnieniem kontekstu jako jednego z warunków skutecznej komunikacji.
PROCES WYWODU: Na wstępie pracy zarysowano ramy teoretyczne wywodu, ukazując językowe aspekty duchowości człowieka. Przyjęto, że jednym z narzędzi kształtowania duchowości młodego człowieka jest głoszenie kazań i homilii. Następnie przeanalizowano język wystąpień dusz‑ pasterskich z punktu widzenia uwarunkowań kontekstowych.
WYNIKI ANALIZY NAUKOWEJ: Z przedstawionych rozważań wynika, że dla skuteczności komunikacyjnej przekazów homiletycznych ważna jest nie tylko treść komunikatu, ale przede wszystkim relacja nadawcy i odbiorcy, odwołania do innych tekstów, a także zachowanie interlokutorów oraz ich uwarunkowania kulturowe.
WNIOSKI, INNOWACJE, REKOMENDACJE: Wnioski wskazują przede wszystkim na przewagę interpersonalną kaznodziei nad słuchaczem. Odzwierciedla się ona zarówno w doborze form językowych, jak i w pozajęzykowym układzie ról. To połączenie wpływa na skuteczność działań mających na celu kształtowanie duchowości dziecka.

Published: June 2022

<p>With the increasing number of applications of internet-of-things (IoT) devices, co-channel interference is unavoidable among coexisting wireless networks, where multiple IoT devices transmit their observations to their respective destinations (access points (APs)). In this scenario, we present a joint precoding and power allocation solution to minimize the mean squared error (MSE), while satisfying power constraints at individual IoT devices. In this regard, first, the necessary feasibility condition for the joint convexity of the optimization problem is derived, ensuring the global optimum solution. Subsequently, based on the solution, an iterative MSE algorithm is formulated and analyzed for convergence. Further analysis shows that the total resulting MSE at APs is limited by the observation signal-to-noise-ratio (SNR). It leads to the inference that in order to avoid the MSE saturation at APs at higher SNRs, the transmit power at IoT devices should be scaled proportional to and less than the observation SNR. Next, we compare the performance of our solution with two classical methods, namely, the minimum variance distortionless precoding (MVDP) and interference alignment (IA) methods, which are modified and enhanced for the given system. Simulations verify the above inference, and the global convergence of the MSE algorithm, with robustness to initializations yielding the better precoders and power allocation as compared to MVDP's and IA's in terms of the averaged total MSE performance.</p>
