Importância das plantas alimentícias não convencionais (PANC) para a segurança alimentar na comunidade Pium (TI Manoá-Pium, Roraima, Brasil)
Authors: Veras Joceline Neide Araújo , Pinho Rachel Camargo de , Machado Ananda
Published: June 2022

As plantas alimentícias não convencionais (PANC) têm uma ou mais categorias de uso alimentício e não fazem parte do dia a dia da maioria da população. Essas plantas têm uma importância em nível planetário, já que a alimentação básica global é cada vez mais homogênea, monótona e globalizada. Apesar de serem “não convencionais” para a maioria das pessoas, muitas PANC são familiares e importantes para as populações tradicionais, especialmente para a sua segurança alimentar. No caso das comunidades indígenas, a relação com a terra faz parte da segurança alimentar. Entretanto, os padrões de produção e de consumo de alimentos que hoje prevalecem em algumas comunidades indígenas não são muito bons porque são artificiais. O objetivo deste trabalho foi contribuir para a segurança alimentar por meio da valorização dos alimentos tradicionais e das PANC na comunidade indígena Pium, região Serra da Lua, Roraima. Foi feita uma descrição da percepção de moradoras da comunidade sobre a alimentação no passado e presente; também foi realizado um levantamento de PANC cultivadas por elas; e foi desenvolvida uma experiência de plantio diversificado orgânico, em parceria com a escola. A descrição das PANC e seu uso foram feitas também na língua Wapichana, que é cooficializada no município de Bonfim, onde foi realizado o estudo. É importante continuar uma análise sobre alimentação saudável, para estimular a população a plantar mais PANC e também continuar plantando as plantas tradicionais nas suas roças, hortas, quintais, visando à segurança alimentar e à conservação da cultura.
“Mulher-pajé”: Cosmopolítica do corpo na festa do wira’u haw Tenetehar-Tembé
Authors: Ponte Vanderlúcia da Silva
Published: June 2022

O presente artigo analisa os processos de transformação/fabricação do corpo da mulher Tembé na festa do wira’u haw para se constituir “mulher-pajé”. Com base na noção de pessoa e corporalidade, na etnografia do ritual nas aldeias Teko-haw e Sede e nas narrativas míticas, busco entender as agências, os pontos de vista e as capacidades que os corpos das meninas-moças potencializam nas correlações com as Karuwar(s): Zawar/onça/pajé e Zahy/lua/pajé, e com o espírito de Verônica Tembé, no sistema sociocósmico. É por meio da cosmopolítica do corpo que a menina-moça, nas três fases do ritual, a tocaia, a festa do mingau e a festa do moqueado, aprende, com as velhas mulheres, a construir a sua coexistência de mulher-pajé.

Published: June 2022

The migration of millions of Venezuelans to South American countries in the last two or three decades is one of the most significant social phenomena in the continent’s history. This article presents a brief historical account of the process and describes a variety of dramatic aspects of the migrants’ experiences throughout the long road towards Colombia, Ecuador, Perú and other countries. The main socio-demographic characteristics of the migrant population (numbers, population types, geographic location in the host country, age, gender and civil status, work and employment) in the above three countries, are described as a relevant basis of further inquiries on the repercussions of migration on the mental health of its protagonists. The information covers important aspects of the journey and the arrival as the initiation of a painful and uncertain process of acculturation and adaptation.

Liquid biopsies in primary and secondary bone cancers
Authors: Ucci Argia , Rucci Nadia , Ponzetti Marco
Published: June 2022

Liquid biopsies are a powerful tool to non-invasively analyze tumor phenotype and progression as well as drug resistance. In the bone oncology field, liquid biopsies would be particularly important to develop, since standard biopsies can be very painful, dangerous (e.g., when found in proximity to the spinal cord), and hard to collect. In this review, we explore the recent advances in liquid biopsies in both primary (osteosarcoma and Ewing sarcoma) and secondary bone cancers (breast, prostate, and lung cancer-induced bone metastases), presenting their current role and highlighting their unexpressed potential, as well as the barriers limiting their possible adoption, including costs, scalability, reproducibility, and isolation methods. We discuss the use of circulating tumor cells, cell-free circulating tumor DNA, and extracellular vesicles for the purpose of improving diagnosis, prognosis, evaluation of therapy resistance, and driving therapy decisions in both primary and secondary bone malignancies.
Electrochemotherapy using thin-needle electrode improves recovery in feline nasal planum squamous cell carcinoma - a translational model
Authors: Tellado Matías , Michinski Sebastián , Impellizeri Joseph , Marshall Guillermo , Signori Emanuela , Maglietti Felipe
Published: June 2022

Aim: Cutaneous squamous cell carcinoma (cSCC) is a common disease in patients exposed to UV-light and human papillomavirus. Electrochemotherapy, a well-established treatment modality with minimum side effects in human and veterinary medicine, circumvents chemoresistance to bleomycin by the use of electric fields. However, patients are sensitive to the trauma produced by the insertion of the needles that lengthen recovery times, particularly cats with nasal planum cSCC. To address this matter, we developed thin-needles electrodes. Methods: Thin-needles electrodes developed using computer simulations and plant tissue models were compared to standard electrodes. A prospective non-randomized study recruiting 52 feline patients with nasal planum cSCC was performed. Local response, anorexia, and overall survival were evaluated. Results: Computer simulations and plant model experiments showed satisfactory results with both electrodes. The patients treated with the thin-needle electrode obtained similar local response rates compared to the standard group, OR 97.3% vs. 80%, respectively (P < 0.067). Most patients in the thin-needle group resumed eating in less than 48 h, as the anorexia was significantly lower (P < 0.0001). Using the standard electrode, most patients took 3 to 5 days to resume normal feeding. The electric current circulating in the standard electrode was 44% higher, contributing to a longer duration of anorexia due to tissue damage. The overall survival in both groups was similar. Conclusion: Electrochemotherapy using thin-needle electrodes provides equivalent local response rates and overall survival compared with standard electrodes but significantly reduced return to appetite after the treatment. These results may be useful in the development of new electrodes for human patients.
Mechanical Wave Concepts: Composing of Five-Step Conception Diagnostic Test, Validity and Reliability Test, and Student’s Profile Conception Level
Authors: Andriani Aretha Patricia , Ermawati Frida Ulfah
Published: June 2022

A mechanical wave is one of the Physics concepts related to everyday life. When the Authors interviewed some students at one of Gersik’s senior high schools, the Authors found that some students didn’t understand the concepts yet. Students thought that when a rope was moved up-down, the particles in the rope would be moved horizontally. The truth is that there was no movement of particles in the vibrated rope. Misconceptions must be detected immediately so as not to interfere with students' understanding of the following concepts. One way is by using a conception diagnostic test. The paper aims to report the composition of the five-step conception diagnostic test for Mechanical Wave concepts, its’ validity and reliability, and use it to identify students’ profile conception level in a Gresik’s senior high school. This study used ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model and data collection technique that used was developing of five-step question that passed through the validity and reliability stages. 13 questions were written and tested for their internal validity and 12 only questions declared valid 91.32%. The result of external validity in terms of a true fake (TF) and a wrong fake (WF) was 7.14% and 4.76% (valid as empirical content because of the TF and WF<10%). The conception diagnostic test was also valid as an empirical construct based on the Pearson Product Moment score because rab=0.575>rtable=0.4575 (significance level of 0.05), and 11 questions were finally declared valid and reliable. 40.40% of the 18 students for their profile conception level confirmed as Lack of Knowledge.

Authors: Alisia Novi , Lesmono Albertus Djoko , Yushardi Yushardi
Published: June 2022

Physics is very well known as a difficult science to understand because it contains many complex mathematical formulas and calculations that can affect student learning outcomes and motivation. To overcome this situation, it is necessary to innovate teaching materials, namely with android-based modules. Almost all students now have a smartphone. An android-based physics module was developed to improve student learning outcomes and motivation. This research is a Research and Development (R&D) research using a Nieveen research design which includes 1) preliminary research, 2) the design stage (prototype stage), and 3) the assessment stage. The android-based module was validated by two expert validators who are lecturers of Physics Education at the University of Jember, obtaining the same score of 75 in the valid category. As for the validation results, the user validator, a physics teacher at MA Raudaltul Ulum obtained a score of 92.8 with a very valid category. To find out the increase in student learning outcomes, pre-test and post-test questions were given. The pre-test and post-test results were analyzed using the N-gain test and obtained a score of 0.72 in the high category. Learning motivation is done by distributing questionnaires. The distribution of the questionnaire was carried out after learning using an android-based module.

Sound Feedback for Social Distance: The Case for Public Interventions During a Pandemic
Authors: Primett William , Silva Hugo Plácido Da , Gamboa Hugo
Published: June 2022

Within the field of movement sensing and sound interaction research, multi-user systems have gradually gained interest as a means to facilitate an expressive non-verbal dialogue. When tied with studies grounded in psychology and choreographic theory, we consider the qualities of interaction that foster an elevated sense of social connectedness, non-contingent to occupying one’s personal space. In reflection of the newly adopted social distancing concept, we orchestrate a technological intervention, starting with interpersonal distance and sound at the core of interaction. Materialised as a set of sensory face-masks, a novel wearable system was developed and tested in the context of a live public performance from which we obtain the user’s individual perspectives and correlate this with patterns identified in the recorded data. We identify and discuss traits of the user’s behaviour that were accredited to the system’s influence and construct 4 fundamental design considerations for physically distanced sound interaction. The study concludes with essential technical reflections, accompanied by an adaptation for a pervasive sensory intervention that’s finally deployed in an open public space.
“I Think That’s the Most Beneficial Change That WIC Has Made in a Really Long Time”: Perceptions and Awareness of an Increase in the WIC Cash Value Benefit
Authors: Duffy Emily W. , Vest Daniele A. , Davis Cassandra R. , Hall Marissa G. , De Marco Molly , Ng Shu Wen , Taillie Lindsey Smith
Published: June 2022

During the COVID-19 pandemic, WIC increased the Cash Value Benefit (CVB) for fruits and vegetables by roughly $25/month/person. We sought to understand WIC participant perceptions of this change and barriers and facilitators to using the CVB. We conducted 10 virtual focus groups (5 rural, 5 urban/suburban) with WIC participants (n=55) in North Carolina in March 2022. Focus groups were recorded and transcribed. We open coded the content and used thematic analysis to uncover consistencies within and between sampled groups. Participants expressed favorable perceptions of the CVB increase and stated the pre-pandemic CVB amount was insufficient. Barriers to using the increased CVB were identifying WIC approved fruits and vegetables in stores and insufficient supply of fruits and vegetables. Barriers were more pronounced in rural groups. CVB use facilitators were existing household preferences for fruits and vegetables and the variety of products that can be purchased with the CVB relative to other components of the WIC food package. Participants felt the CVB increase allowed their families to eat a wider variety of fruits and vegetables. The CVB increase may improve fruit and vegetable intake, particularly if made permanent, but barriers to CVB and WIC benefit use may be limiting the potential impact.
Socioeconomic-Related Inequalities in COVID-19 Vulnerability in South Africa
Authors: Shifa Muna , Gordon David , Leibbrandt Murray , Zhang Mary
Published: June 2022

To contain and mitigate the coronavirus (COVID-19) pandemic, African governments have implemented non-pharmacological interventions (NPIs), such as imposing travel bans, confining people to their homes and closing schools, shops and workplaces. These NPIs are likely to be less effective in circumstances where people need to leave their homes to work, collect food, water and cooking fuel or where people cannot maintain distancing due to overcrowded living environments. Using data from the nationally representative South African General Household Survey 2019, we examined individuals’ vulnerability to the risk of COVID-19 infection due to their health, socioeconomic and living circumstances. We explored socioeconomic-related inequalities in COVID-19 using concentration curve and concentration index methods. Our results showed that vulnerability to COVID-19 was disproportionately concentrated among those with low socioeconomic status. Using the Recentered Influence Function decomposition approach, we found that higher income and education had a significant and positive impact on reducing socioeconomic-related COVID-19 vulnerability. Conversely, people with lower socioeconomic status were more likely to live in circumstances that made compliance with NPI requirements almost impossible, and they were also more likely to have pre-existing health conditions that made them more vulnerable to COVID-19.
Investigating the Relationship between Facial Mimicry and Empathy
Authors: Kovalchuk Yevgeniya , Budini Elizabeta , Cook Robert , Walsh Andrew
Published: June 2022

Facial expressions play a key role in interpersonal communication when it comes to negotiating our emotions and intentions, as well as interpreting those of others. Research has shown that we can connect to other people better when we exhibit signs of empathy and facial mimicry. However, the relationship between empathy and facial mimicry is still debated. Among the factors contributing to the difference in results across existing studies is the use of different instruments for measuring both empathy and facial mimicry, as well as often ignoring the differences across various demographic groups. This study first looks at the differences in empathetic abilities of people across different demographic groups based on gender, ethnicity and age. The empathetic ability is measured based on the Empathy Quotient capturing a balanced representation of both emotional and cognitive empathy. Using statistical and machine learning methods, the study then investigates the correlation between the empathetic ability and facial mimicry of subjects in response to images portraying different emotions displayed on a computer screen. Unlike the existing studies measuring facial mimicry using electromyography, this study employs a technology detecting facial expressions based on video capture and deep learning. This choice was made in the context of increased online communication during and post the COVID-19 pandemic. The results of this study confirm the previously reported difference in the empathetic ability between females and males. However, no significant difference in the empathetic ability was found across different age and ethnic groups. Furthermore, no strong correlation was found between empathy and facial reactions to faces portraying different emotions shown on a computer screen. Overall, the results of this study can be used to inform the design of online communication technologies and tools for training empathy team leaders, educators, social, and health care providers.

Introduction: The development of effective vaccines has partially mitigated the trend of the SARS-CoV-2 pandemic, however, the need for orally available antiviral drugs persists. This study aims to investigate the activity of molnupiravir in combination with nirmatrelvir or GC376 on SARS-CoV-2 to verify the synergistic effect. Methods: The SARS-CoV-2 strains 20A.EU, BA.1 and BA.2 were used to infect Vero E6 in presence of antiviral compounds alone or in combinations using 5 two-fold serial dilution of compound concentrations ≤EC90. After 48 and 72 h post-infection, viability was performed using MTT reduction assay. Supernatants were collected for plaque-assay titration. All experiments were conducted three times and in triplicate. The synergistic score was calculated using Synergy Finder version 2. Results: All compounds reached micromolar EC90. Molnupiravir and GC376 showed a synergistic activity at 48 h with an HSA score of 19.33 (p<0.0001) and an additive activity at 72 h with an HSA score of 8.61 (p<0.0001). Molnupiravir and nirmatrelvir showed a synergistic activity both at 48 h and 72 h with an HSA score of 14.2 (p=0.01) and 13.08 (p<0.0001), respectively. Conclusion: Molnupiravir associated with one of the two protease-inhibitors nirmatrelvir and GC376 showed good additive-synergic activity in vitro.
Fermat’s Last Theorem Proved in Hilbert Arithmetic. III. The Quantum-Information Unification of Fermat’s Last Theorem and Gleason’s Theorem
Authors: Penchev Vasil
Published: June 2022

The previous two parts of the paper (correspondingly, https://philpapers.org/rec/PENFLT-2 and https://philpapers.org/rec/PENFLT-3) demonstrate that the interpretation of Fermat’s last theorem (FLT) in Hilbert arithmetic meant both in a narrow sense and in a wide sense can suggest a proof by induction in Part I and by means of the Kochen - Specker theorem in Part II. The same interpretation can serve also for a proof FLT based on Gleason’s theorem and partly similar to that in Part II. The concept of (probabilistic) measure of a subspace of Hilbert space and especially its uniqueness can be unambiguously linked to that of partial algebra or incommensurability, or interpreted as a relation of the two dual branches of Hilbert arithmetic in a wide sense. The investigation of the last relation allows for FLT and Gleason’s theorem to be equated in a sense, as two dual counterparts, and the former to be inferred from the latter, as well as vice versa under an additional condition relevant to the Gödel incompleteness of arithmetic to set theory. The qubit Hilbert space itself in turn can be interpreted by the unity of FLT and Gleason’s theorem. The proof of such a fundamental result in number theory as FLT by means of Hilbert arithmetic in a wide sense can be generalized to an idea about “quantum number theory”. It is able to research mathematically the origin of Peano arithmetic from Hilbert arithmetic by mediation of the “nonstandard bijection” and its two dual branches inherently linking it to information theory. Then, infinitesimal analysis and its revolutionary application to physics can be also re-realized in that wider context, for example, as an exploration of the way for physical quantity of time (respectively, for time derivative in any temporal process considered in physics) to appear at all. Finally, the result admits a philosophical reflection of how any hierarchy arises or changes itself only thanks to its dual and idempotent counterpart.
Fuzzy Artificial Intelligence Based Control Strategy Applied to an Electromagnetic Frequency Regulator in Wind Generation Systems
Authors: Crisóstomo Daniel C. C. , Do Nascimento Thiago F. , Nunes Evandro A. F. , Villarreal Elmer , Pinheiro Ricardo , Salazar Andrés
Published: June 2022

This paper presents the implementation of a control strategy based on fuzzy logic artificial intelligence (AI) for speed regulation of an electromagnetic frequency regulator (EFR) prototype, aiming to eliminate the dependence on knowledge of physical parameters in the most diverse operating conditions. Speed multiplication is one of the most important steps in power generation wind. Gearboxes are generally used for this purpose. However, they have a reduced lifespan and a high failure rate and are still noise sources. The search for new ways to match the speed (and torque) between the turbine and the generator is an important research area to increase the energy, financial and environmental efficiency of wind systems. The EFR device is an example of an alternative technology that this team of researchers has proposed. It counts the fact of taking advantage of the main advantages of an induction machine with the rotor in a squirrel cage positively. In the first studies, the EFR control strategy consisted of the conventional PID controllers, which has several limitations widely discussed in the literature. This strategy also limits the EFR's performance, considering its entire operating range. The simulation program was developed using the Matlab/Simulink platform, while the experimental results were obtained in the laboratory emulating the EFR-based system. The EFR prototype used has 2 poles, a nominal power of 2.2 kW, and a nominal frequency of 60 Hz. Experimental results were presented to validate the efficiency of the proposed control strategy.
Physics Teachers’ Perceptions about their Judgment within Differentiated Learning Environment: An Implication for Technology Implementation
Authors: Santoso Purwoko Haryadi , Istiyono Edi , Haryanto Haryanto
Published: June 2022

There is a national shift in the new Indonesian curriculum to employ differentiated learning approach in addressing diversity of students’ needs and abilities. Teachers’ judgment obviously corresponds to the duty that takes physics teachers to monitor their students at individual level. Within Indonesian physics education research (PER) context, empirical study that has addressed this subject is still lacking. To fill this gap, eight Indonesian physics teachers’ experiences and limitations about their judgment within differentiated learning environment has been investigated through phenomenological study. Physics teachers were voluntarily recruited after they have declared their endorsement and personal consent to participate in the study. Our participants were distributed over several teaching experiences, geographic regions, and ICT experiences. The latter experience might be taken into account since, through this study, we would project upcoming developmental research about engaging recent technological approaches to cope limitations of teachers’ judgment. Online semi-structured interviews (~ 50 min) were conducted by the first author (P.H.S.) to all physics teachers. Other authors contributed in reviewing the interview protocol (E.I. and H) and training the first author’s pilot interview (H.R.). Model of teachers’ thought and action was implemented to uncover physics teachers’ experiences and limitations in making judgment within diverse students. Findings revealed that physics teachers have conceded that they should adapt learning process in order to meet heterogeneous students’ needs. Personal observation has mainly informed teachers to identify students’ differences. After students have been identified, they creatively designed learning transformations to accommodate spectrum of students’ abilities. Nevertheless, we discovered several limitations encountered by teachers particularly in terms of judgments’ equity, accuracy, and their workload. To overcome this, teachers indicated various and supportive attitudes about technology implementation to assist their judgment. Implications for technological development was provided to address obstacles during the teachers’ judgment.

Published: June 2022

Nowadays molecular and immunological research is essential for the better understanding of tumor cells pathophysiology. The increasing number of neoplasms is taken under ‘the molecular magnifying glass’ therefore it is possible to discover complex relationships between cytophysiology and immune system action. An example could be renal cell carcinoma (RCC) which has deep interactions with immune mediators such as Interleukin 17 (IL-17) - an inflammatory cytokine reacting to tissue damage and external pathogens. RCC is one of the most fatal urological cancer because of its often late diagnosis and poor susceptibility to therapies. IL-17 and its relation with tumors is extremely complex and constitute a recent topic for numerous research. What is worth highlighting is IL-17 dual character in cancer development - it could be pro- as well as antitumorigenic. The aim of this review is to summarize the newest data considering multiple connections between IL-17 and RCC.
SailBuoy Ocean Currents:Low Cost Upper Layer Ocean Current Measurements
Authors: Wullenweber Nellie , Hole Lars Robert , Ghaffari Peygham , Graves Inger , Tholo Harald , Camus Lionel
Published: June 2022

This study introduces an alternative to the existing methods for measuring ocean currents based on a recently developed technology. The SailBuoy is an unmanned surface vehicle powered by wind and solar panels that can navigate autonomously to predefined way-points and record velocity profiles using an integrated downward-looking Acoustic Doppler Profiler (ADCP). Data, collected on two validation campaigns, shows a satisfactory correlation between the SailBuoy current records and traditional observation techniques such as bottom mounted and moored current profilers and moored single-point current meter. While the highest correlations were found in tidal signals, strong current, and calm weather conditions, low current speeds and varying high wave and wind conditions reduced correlation considerably. Filtering out some events with high sea surface roughness associated with high wind and wave conditions may increase the SailBuoy ADCP listening quality and lead to better correlations. Not yet resolved is a systematic offset between the measurements obtained by the SailBuoy and the reference instruments of ± 0.03 m/s. Possible reasons are discussed to be the differences between instruments (various products) as well as changes in background noise levels due to environmental conditions.
Flat Slabs in Eccentric Punching Shear: Experimental Database and Code Analysis
Authors: Vargas Daniel , Lantsoght Eva O.L. , Genikomsou Aikaterini
Published: June 2022

Eccentric punching shear can occur in concrete slab-column connections when the connection is subjected to shear and unbalanced moments. Typically, this situation results in edge and corner columns and is thus a common practical case. However, most punching experiments in the literature are concentric punching shear. This paper presents a developed database of eighty-eight experiments of flat slabs under eccentric punching shear, including a summary of the testing procedure of each reference and a description of the slab specimens. Additionally, a linear finite element analysis of all the specimens is included to determine the relevant sectional shear forces and moments. Finally, the ultimate shear stresses from the database experiments are compared to the shear capacities determined with ACI 318-19, Eurocode 2 NEN-EN 1992-1-1:2005, and the Model Code 2010. The comparison shows that the Model Code 2010 is the most precise in the predictions with an average tested over predicted ratio of 0.96 and a coefficient of variation of 27.96%. It can be concluded that this study represents the inconsistencies of the currently used design methods and the lack of experimental information.

The research sample used was 30 science class students consisting of X science 1, X science 2, and X science 3 SMAN 10 Muaro Jambi. The sampling technique used is random sampling. The instruments used in this study were scientific process skills observation sheets and analytical thinking skills assessment questions. The regression analysis was used to determine how the variables were used. This study obtained the results after students used a practical guide based on science process skills. Students had good science process skills. The science process skill variable affected the students’ analytical thinking ability by 52.2%, and other variables influenced the remaining 47.8%. The impact of the research that researchers expect is that teachers can innovate the learning process using e-modules based on science process skills to improve other abilities possessed by students.

This paper presents an optimization study of an adsorption solar refrigerator through dynamic modeling and simulation of the system behavior using the zeolite/water couple. Thus, a mathematical model representing the evolution of heat and mass transfer at each component of the adsorption solar refrigerator has been developed. The results of this study showed that increasing the angle of inclination of the collector from 0° to 13° with respect to the horizontal causes an increase in the temperature of the zeolite. The result is an increase in the mass of water vapor cycled, but also an improvement in the performance of the solar refrigerator. When the value of the angle of inclination exceeds 13°, the mass of water vapor cycled decreases and subsequently leads to a decrease in the performance of the refrigeration system.

In this paper, the study is focused on the anti-reflection coatings on silicon solar cells and monocrystalline solar cells. The impact of optical parameters such as refractive index on the reflectivity as well as the impact of the as well as the impact of the diffusion length of the carriers was studied. The calculations performed according to the transfer matrices on the stacking of layers through the diopters have allowed establishing simulations for antireflective multilayer coatings. In our study, the reference wavelength was chosen equal to l= 700 nm, which gives us an optimal refractive index of silicon (n = 3.7838) corresponding to a reflectivity at the surface of 33%. To reduce this high reflectivity, the coating of the surface is a technique used to improve the transmission of the incident luminous flux in the active material and light flux in the active material which is silicon.

Background:

Polyethylene bearing design may influence the risk of revision after total knee arthroplasty (TKA). Previous investigations from outside of the United States have suggested the potential for an increased risk of all-cause revision and revision for infection with the use of posterior-stabilized bearings. We examine the risk of revision based on the polyethylene bearing design selection for primary TKA.

Methods:

An analysis of the American Joint Replacement Registry (AJRR) data from 2012 to 2019 was performed. We identified all primary TKAs over the study period and linked cases to supplemental U.S. Centers for Medicare & Medicaid Services (CMS) data where available. Patient demographic characteristics, polyethylene characteristics, procedure dates, and cause for revision were recorded. Analysis was performed to compare minimally stabilized implants (cruciate-retaining, anterior-stabilized, or pivot bearing designs) with posterior-stabilized implants. Cumulative incidence function (CIF) curves and Cox proportional hazard ratios (HRs) were created for all-cause revision and revision for infection in each group.

Results:

We identified 305,279 cases with reported minimally stabilized or posterior-stabilized implant characteristics. There were 161,486 cases (52.9%) that utilized posterior-stabilized bearings compared with 143,793 cases (47.1%) with minimally stabilized bearings. For minimally stabilized bearings, 1,693 cases (1.18%) had all-cause revision and 334 cases (0.23%) had revision for infection. For posterior-stabilized bearings, 2,406 cases (1.49%) had all-cause revision and 446 cases (0.28%) had revision for infection. The use of posterior-stabilized bearings had HRs of 1.25 (95% confidence interval [CI], 1.2 to 1.3; p < 0.0001) for all-cause revision and 1.18 (95% CI, 1.0 to 1.4; p = 0.02) for revision for infection.

Conclusions:

Similar to investigations from international registries, we found an increased risk of all-cause revision and revision for infection when using posterior-stabilized bearings in TKA in the United States. Surgeons should consider this finding when considering bearing selection for primary TKA.

Understanding Noise Exposure During Cast Removal
Authors: Shaw K. Aaron , Mueller Casey , Biolzi Francesco , Villani Nolan , O’Brien Frederick , Burks Robert
Published: June 2022

Background:

Cast removal can be associated with considerable noise exposure, especially impacting the pediatric patient and provider. Although noise generation from cast saws has been deemed safe by the U.S. Occupational Safety and Health Administration and the U.S. Centers for Disease Control and Prevention standards, there are no current studies on the effects of cast material on noise levels generated.

Methods:

A simulated casting model utilizing plaster, fiberglass, and plaster with fiberglass overwrapping was used for experimental testing. Four different casting conditions were tested, with 5 samples in each group. Samples were tested using 2 different cast saws: a standard cast saw and a quiet saw. Each saw was used for 30 seconds of continuous cutting for each sample, measuring peak, mean, and minimum sound levels in decibels with sound level meters. Noise levels were measured at 18, 36, and 72 in (20, 91, and 183 cm) from the saw, comparing saw and cast types against ambient noise and baseline cast-saw noises. Between-group comparisons were performed using univariate analyses.

Results:

Mean noise generation differed between casting materials, with plaster material demonstrating significantly greater noise levels than fiberglass casts at all distances for each saw type. Increasing fiberglass thickness significantly increased the mean noise levels with standard (18-in distance for 10 and 5 ply: 87.4 and 85.8 dB; p = 0.0004) and quiet cast saws (78.3 and 76.1 dB; p = 0.041. Additionally, the quiet cast saw provided a 5.7 to 10.6 dB reduction in mean and peak noise levels, varying by casting material and distance.

Conclusions:

Occupational noise exposure can be mitigated with the use of fiberglass casting material that is not >5 ply in thickness, with a quiet cast saw for removal. The use of a quiet cast saw substantially decreased noise exposure to patients and staff members over standard orthopaedic cast saws.

Background:

The specific advantages of spinal anesthesia compared with general anesthesia for primary total hip arthroplasty (THA) remains unknown. Therefore, this study aimed to investigate the pain control, length of stay, and postoperative outcomes associated with spinal anesthesia compared with general anesthesia in a large cohort of primary THAs from a single, high-volume academic institution.

Methods:

We retrospectively identified 13,730 primary THAs (11,319 patients) from 2001 to 2016 using our total joint registry. Of these cases, 58% had general anesthesia and 42% had spinal anesthesia. The demographic characteristics were similar between groups, with mean age of 64 years, 51% female, and mean body mass index (BMI) of 31 kg/m2. Data were analyzed using an inverse probability of treatment weighted model based on a propensity score that accounted for numerous patient and operative factors. The mean follow-up was 6 years.

Results:

Patients treated with spinal anesthesia had lower Numeric Pain Rating Scale (NPRS) scores (p < 0.001) and required fewer postoperative oral morphine equivalents (OMEs) at all time points evaluated (p < 0.001). Patients treated with spinal anesthesia also had shorter hospital length of stay (p = 0.02), fewer altered mental status events (odds ratio [OR], 0.7; p = 0.02), and fewer intensive care unit (ICU) admissions (OR, 0.7; p = 0.01). There was no difference in the incidence of deep vein thrombosis (p = 0.8), pulmonary embolism (p = 0.4), 30-day readmissions (p = 0.17), 90-day readmissions (p = 0.18), all-cause revisions (p = 0.17), or all-cause reoperations (p = 0.14).

Conclusions:

In this large, single-institution study, we found that spinal anesthesia was associated with reduced pain scores and OME use postoperatively. Furthermore, spinal anesthesia resulted in fewer altered mental status events and ICU admissions. These data favor the use of spinal anesthesia in primary THAs.
