Across-Depth Heterogeneity and Irreversibility of Fast-Charge-Driven Lithium Plating
Authors: Son Seoung-Bum , Trask Steve , Tsai Yifen , Lopykinski Susan , Kim Minkyu , Bloom Ira
Published: May 2022

Enabling fast charging in lithium-ion batteries (LIBs) is a key factor for resolving consumers’ “range anxiety” concerns in choosing an electric vehicle over a gasoline-powered one. The best-known issue in the fast charging of current LIBs (based on LiNixMnyCo1−x−yO2/graphite) is lithium plating, which is barely reversible and is accompanied by capacity loss over time. Therefore, understanding the reasons for the irreversibility of lithium plating driven by fast charging is critical to enhancing the fast-charging capability of LIBs. Here, a study of the irreversibility and heterogeneity of lithium plating is carried out by using electrochemical analyses, inductively coupled plasma mass spectroscopy, and X-ray photoelectron spectroscopy. The study shows that the majority of the lithium plated during fast charging remains inactive even with very slow discharging rates, implying that most of the plated lithium is irreversibly lost. The study also reveals that chemical compounds such as LiF, Li2O and Li2(CO3) are formed heterogeneously within the lithium plating and are responsible for some of the irreversibility of the plated lithium.
Inhibiting the Oxygen Reduction Reaction Kinetics on Carbon Fiber Epoxy Composites Through Diazonium Surface Modification-Impacts on the Galvanic Corrosion of Coupled Aluminum Alloys
Authors: Dammulla Isuri N. , Swain Greg M.
Published: May 2022

We report on the chemical modification of carbon fiber reinforced polymer (CFRP) composites by the electrochemical reduction of 4-nitrophenyl (NP) and 4-nitroazobenzene (NAB) diazonium salts. The electrochemically assisted modification of the exposed carbon fibers was accomplished using cyclic voltammetry from 0.6 to −0.5 V (vs Ag QRE) for 25 cycles in deaerated acetonitrile containing 0.1 M tetrabutylammonium tetrafluoroborate (NBu4BF4) and 5 mM aryldiazonium salt. Raman spectra of the modified composites confirmed the formation of stable 4-NP and 4-NAB adlayers. The influence of diazonium surface pretreatment on the oxygen reduction reaction (ORR) kinetics was assessed by measuring the voltametric curves for dissolved oxygen reduction on unmodified and chemically modified composites in naturally aerated 0.5 M Na2SO4. The adlayers are believed to reduce the kinetically controlled current for the ORR by blocking reactive surface sites for O2 chemisorption. Results show the adlayers are stable during a 7-day continuous neutral salt spray (NSS) exposure and the extent of galvanic corrosion on trivalent chromium process (TCP) conversion-coated aluminum alloys is significantly reduced when joined with a surface treated composite. The extent of carbon corrosion and microstructural degradation of carbon fibers is also reduced by the organic adlayers.
Study on Damage of the OGFC Mixture Based on Characteristics of Void Distribution
Authors: Xu-qiu Teng , Dongdong Zhao , Fuqiang Zhang
Published: May 2022

The void distribution characteristics of the drainage asphalt mixture have a certain influence on its durability. In this paper, X-ray CT technology and digital image processing technology are used to study the void distribution characteristics of three different graded asphalt mixtures, and the void ratio, void quantity, void equivalent diameter, and void fractal dimension of drainage asphalt mixtures are determined. On this basis, the damage characteristics of the asphalt mixture are analyzed with the split strength as the index, and the relationship between the void fractal dimension and the split strength is established. The relationship between the void diameter and the durability of the OGFC mixture is determined by the influence of the void diameter on the void fractal dimension. The results show that the void distribution characteristics of the OGFC mixture have a significant impact on its durability. The void larger than 3 mm in OGFC asphalt mixture has a greater impact on the durability of asphalt mixture. Even if the void ratio of different OGFC mixtures is relatively close, its durability is also very different. The difference in durability is mainly due to the difference of the void structure and the proportion of the number of large voids above 5 mm.

Authors: Pallant Benjamin A. , Moore Claire E. , Topor Lisa Swartz
Published: May 2022

Background/Objective. Thyrotoxicosis, a condition resulting from excessive peripheral thyroid hormone, is typically accompanied by thyroid function tests demonstrating a high free thyroxine (free T4) with appropriate suppression of thyroid-stimulating hormone (TSH). Case report. We describe a 17-year-old female presenting with symptoms of thyrotoxicosis along with suppressed TSH and low free T4, a laboratory pattern concerning for central hypothyroidism. Further history revealed that she was prescribed liothyronine as an adjunct therapy for depression. Discussion. Due to the short half-life of liothyronine, clinical signs and symptoms of thyrotoxicosis may develop before detection by interval lab monitoring. Conclusion. This case highlights the need for close monitoring and caution when treating adolescents with liothyronine and the importance of interpreting atypical laboratory findings within clinical context.

Authors: Ha Jang Woo , Pyo Jung Yoon , Ahn Sung Soo , Song Jason Jungsik , Park Yong-Beom , Lee Sang-Won
Published: May 2022

Objectives. This study investigated the frequency and patterns of interstitial lung disease (ILD) and their clinical effect on all-cause mortality during the follow-up period in patients with antineutrophil cytoplasmic antibody- (ANCA-) associated vasculitis (AAV) in Korea. Methods. The medical records of 255 AAV patients with ILD were retrospectively reviewed. ILD and its patterns, the usual interstitial pneumonia (UIP) and non-UIP patterns, were confirmed using high-resolution computed tomography both at AAV diagnosis and during follow-up. Forced vital capacity (FVC) and diffusing capacity of the lung for carbon monoxide (DLCO) were also obtained. Results. The median age was 65.0 years, and 34.9% were male. ILD occurred in 53 patients, among whom 49.1% developed ILD after AAV diagnosis. Among AAV subtypes, the frequencies of ILD were significantly higher in both patients with microscopic polyangiitis (MPA) and those with AAV having myeloperoxidase (MPO)-ANCA (or P-ANCA) compared to other subtypes. However, there was no statistical significance in AAV subtypes or FVC/DLCO ratio between patients with the UIP and non-UIP patterns. In particular, the cumulative patients’ survival rate was lower in patients with AAV and ILD than in those without ILD. Conclusions. ILD occurred in one-fifth of Korean patients with AAV in this study and was associated with MPA and MPO-ANCA (or P-ANCA). In addition, ILD significantly increased the rate of all-cause mortality in these patients with AAV. Therefore, we suggest the need for more attention and more frequent regular visit for patients with AAV and ILD regardless of the time of ILD occurrence.

Published: May 2022

Integrating machine learning into one of the manufacturing processes, i.e., forging, is mainly concerned with making the system more intelligent by incorporating them to exhibit global understanding. Sometimes the engineer/operator can find the defects during or after the forging operation. So, the system will need some input to identify the different types of categorized defects. And also, according to that, we will develop the intelligent fault diagnosis process. We should calculate the statistical probability theory. Now, we implement the system which is the structure of the fault analysis system for the forging process. In the structure, we demonstrate the defect of the forged part, use the given imported probability to find the possible causes, and provide some remainders to reduce the fault. For enhancement of feature needs, this work includes more integration of AI with forging.
Central Diabetes Insipidus Induced by Acute Myeloid Leukemia with DNMT3A Mutation
Authors: Lakshmanan Priyanka , Asnani Heena , Knorr David
Published: May 2022

Central diabetes insipidus (CDI) is an uncommon complication of acute myeloid leukemia (AML). Patients present with polyuria either preceding or at the time of diagnosis of AML. We describe the case of a 36-year-old male who presented with a subacute onset of polyuria, polydipsia, nocturia, and fatigue. After an extensive workup, he was diagnosed with AML/CMML (chronic myelomonocytic leukemia) with a normal karyotype with DNMT3A, CBFB, and PTPN11 mutations. Further workup of the polyuria with a water deprivation test helped confirm the diagnosis of CDI along with MRI findings suggestive of hypophysitis. In this report, we analyze the clinical workup for AML and CDI and report the possibility of extramedullary leukemic infiltration associated with DNMT3A mutation, which has been reported as one of the mechanisms in the existing literature. We also discuss other theories hypothesized to cause CDI in AML patients with abnormal karyotypes. Our patient progressed to AML from CMML-2 after a cycle of decitabine, with confirmed gingival and presumed central nervous system (CNS) involvement. He is in minimal residual disease (MRD)-negative complete remission after induction with a CNS-active acute lymphoblastic leukemia-2 regimen. He also received double umbilical cord blood transplantation, conditioned with cyclophosphamide, fludarabine, thiotepa, and total body irradiation (TBI) of 4 Gy. This was complicated by engraftment syndrome for which he is currently being managed. CDI of the patient was corrected by desmopressin administration.

Authors: Liu Yun , Luo Xin , Wang Ze-Zheng , Hu Ao , Liu Jia-Bao
Published: May 2022

The preparation of C4 olefins from ethanol has become a research hotspot in the field of chemical product production. Based on the test data of given catalyst combination at different temperatures, a neural network prediction model for the effect of different catalyst combination and temperature on C4 olefin yield is proposed in this paper. Firstly, taking the catalyst combination and temperature as independent variables, the C4 olefin yield is analyzed by multiple regression analysis and evaluated by R-square index. Secondly, on the basis of this experiment, the BP neural network model for predicting the yield of coupling reaction is reconstructed, and the adaptive genetic operator is added to the BP neural network to optimize its threshold, weight, and convergence speed, so as to improve the accuracy of yield prediction. Finally, the prediction results of BP and GA-BP models are compared from five aspects: SSE, MAE, MSE, RMSE, and MAPE. The experimental results show that the improved model has good global optimization ability and high yield prediction accuracy in the prediction of coupling reaction yield. Therefore, the multiple control variable model proposed in this paper has a certain positive significance for predicting the effect of catalyst combination on yield in coupling reaction.
The Effect of Humanized Nursing Intervention Guided by Computed Tomography Images on Elderly Patients Undergoing Anesthesia for Femur Intertrochanteric Fractures under Intelligent Reconstruction Algorithm
Authors: He Yanfang , Li Yufang , Zeng Rong , Zhang Xiaoyan
Published: May 2022

This research was aimed at analyzing the effect of humanized nursing intervention combined with computed tomography (CT) imaging in the surgical anesthesia of femur intertrochanteric fractures (FIF) in the elderly. An image reconstruction algorithm was proposed based on nonlocal mean (NLM) algorithm, which was named as ONLM, and its performance was analyzed. A total of 114 elderly patients with FIF were equally and randomly divided into a humanized nursing group (57 cases) and a routine nursing group (57 cases). They were performed with CT imaging scan based on the ONLM algorithm, and the clinical indicators of the two groups of patients were recorded. The root mean square error (RMSE) and mean absolute error (MAE) of the CT images constructed using the ONLM algorithm were significantly lower than those using NLM algorithm, edge filtering algorithm, and total variation model, while the peak signal-to-noise ratio (PSNR) was the opposite (

P
<
0.05

). The operation time, hospitalization days, intraoperative blood loss, postoperative drainage, and anesthesia preparation time of patients in the humanized nursing group were significantly lower than those in the routine nursing group. The number of patients with excellent Harris scores in the humanized nursing group was higher than that in the routine nursing group, and the number of patients with poor Harris scores was lower (

P
<
0.05

). The language pain score, facial pain score, and visual analog simulation (VAS) scores of patients in the humanized nursing group were significantly lower than those in the routine nursing group. The numbers of postoperative hip varus and fracture nonunion cases in the humanized nursing group were significantly more than those in the routine nursing group. In short, CT images constructed by the ONLM showed higher performance than those by the traditional algorithm. In addition, CT images constructed by ONLM combined with humanized nursing intervention could more effectively improve the cooperation of patients with surgical anesthesia, reduce surgical pain and fear of patients, improve the prognosis of patients, and lower the occurrence of adverse events.

Application of Viscoelastic Tuned Mass Dampers in Vibration Mitigation of Steel Joist Jack Arch Floor Structures
Authors: Nikravesh Fatemeh , Toopchi-Nezhad Hamid
Published: May 2022

A common situation found in many old and modern buildings is the annoying floor vibration. Many old buildings suffer floor vibration as no specific design guidelines were employed to limit the situation. In modern buildings, the development of floors of lighter weight, longer span, and less inherent damping is the main cause for the annoying vibration. In this paper, as a novel application, the influence of viscoelastic tuned mass dampers (TMDs) in vibration mitigation of an existing steel joist jack arch floor structure is investigated using finite element (FE) analysis. Results of a free vibration test conducted on the prototype TMDs are used to validate the FE model. The jack arch floor is subjected to the walking loads of different stepping rates of 1.5, 2, and 3 Hz. Various load models that are available in the literature are used to define the dynamic walking load, and the response mitigation is carried out based on the most critical load models. The influence of design parameters such as the excitation frequency, configuration of the individual dampers in the TMD system, and the mass ratio of the TMD system on the vibration mitigation of the floor structure are investigated in detail. Results of this study indicate that the viscoelastic TMDs are effective in vibration mitigation of jack arch floor structures.

The development of assistive robots is gaining momentum in the robotic and biomedical fields. An assistive robotic system is presented in this research paper for object manipulation to aid people with physical disabilities. The robotic arm design is imported to a simulated environment and tested in a virtual world. This research includes the development of a versatile design and testing platform for robotic applications with joint torque requirements, workspace restrictions, and control tuning parameters. Live user inputs and camera feeds are used to test the movement of the robot in the virtual environment. To create the environment and user interface, a robot operating system (ROS) is used. Live brain computer interface (BCI) commands from a trained user are successfully harvested and used as an input signal to pick a goal point from 3D point cloud data and calculate the goal position of the robots’ mobile base, placing the goal point in the robot arms workspace. The platform created allows for quick design iterations to meet different application criteria and tuning of controllers for desired motion.

Published: May 2022

Background. Ovarian cancer (OC) is the leading cause of gynecologic malignant tumors. The role of necroptosis-related lncRNAs (NRLs) in OC remains unclear. This study aims to explore the association between NRLs and prognosis in OC patients. Methods. The Cancer Genome Atlas (TCGA) and GTEx datasets were used to obtain OC’s data. A NRLs signature associated with overall survival (OS) was constructed by Cox-LASSO regression analysis in training cohort for calculating risk score and then validated in testing cohort. Subsequently, the area under the curve (AUC) and Kaplan–Meier survival analysis were used to evaluate the predictive accuracy of the risk score. Finally, the immune infiltration and functional enrichment were compared between different risk groups. Results. A 8-NRLs signature including AC245128.3, AL355488.1, AC092794.1, AC068888.2, AL590652.1, AC008982.2, FOXP4-AS1, and Z94721.1 was identified to assess the OS of OC. Kaplan–Meier survival analysis, AUC value, and Cox regression analysis confirmed its predictive value and showed that the clinical outcomes were worse for high-risk patients. There were also differences in immunological functioning and immune pathways between the high-risk and low-risk groups. Conclusions. The signature based on eight NRLs has significant values in predicting prognostic prediction in OC, as well as providing a new sight for targeted therapies.

Learn about the benefits of muscle strength training combined with tai chi for adult skeletal muscle in multiple CT scanning. The study included 182 people over the age of 60 with no long-term history of physical activity and exercise. They were divided into the Taijiquan group (52 people), student muscle strength group (45 people), student muscle group combined with Taijiquan group (45 people), and control group (40 people). The board of directors did not attend. The other three groups received tai chi (more than 4 times a week), muscle strength training, and muscle training combined with tai chi for 6 months. Lumbar spine (L1-4) BMD and Berg scores were approximately the same as those measured in adults before exercise and at 3 and 6 months after exercise. The results showed that there were significant differences in the scores of lumbar spine BMD and Berg Balance Scale between the Taijiquan group and students before and after exercise combined with muscle strength training (

P
<

Authors: Jerath Nivedita U.
Published: May 2022

This study presents the clinical and electrophysiological findings of four subjects with a pathogenic heterozygous GDAP1 variant causing Charcot–Marie–Tooth disease 2K (CMT2K) and one additional subject with an uncertain GDAP1 variant and clinical findings of CMT 2K. The study evaluated these five subjects using clinical, laboratory, electrophysiological, and genetic testing. The findings showed that clinical features demonstrated no pes cavus, no significant weakness in the hands or feet, normal reflexes in four out of the five subjects, and mild to normal electrodiagnostic findings. The variant was associated with painful and numb feet with diminished sensation to pinprick. This study suggests that GDAP1 variants may be associated with very mild, predominantly sensory Charcot–Marie–Tooth disease, warranting continuing research for this type of the disease.

Authors: Yu Linxiang , Zhang Bin , Zou Haosheng , Shi Yi , Cheng Liang , Zhang Ying , Zhen Haiwen
Published: May 2022

Objective. To analyze multiple factors developing lung adenocarcinoma lesion from solitary pulmonary nodule (SPN). Methods. A total of 70 patients diagnosed with lung adenocarcinoma after finding SPN by chest CT and treated in our hospital (01, 2018–01, 2021) were selected as the malignant lesion group, and another 70 patients diagnosed with benign lesion after finding SPN by CT in the same period were included in the benign lesion group. All patients had complete medical records. With univariate analysis and multivariate logistic regression, the independent risk factors for developing lung adenocarcinoma lesions from SPN were analyzed. Results. By conducting univariate analysis of patients’ general information (age, course of disease, BMI, nodule diameter, and gender), smoking status (smoking history and number of cigarettes smoked per year), medical history (family history of lung cancer, history of extrapulmonary malignant tumor, and history of autoimmune diseases), basic complications (hypertension and diabetes), and laboratory examinations (CEA, NSE, CYFRA21‐1, SCC‐Ag, and CA125), it was concluded that age, course of disease, nodule diameter, CEA positive, CYFRA21‐1 positive, and CA125 positive were significantly different between the two groups (P < 0.05); the logistic regression results showed that high age, increased nodule diameter, and CYFRA21‐1 positive were the independent risk factors developing lung adenocarcinoma from SPN (P < 0.05). Conclusion. In patients with SPN, higher age, longer course of disease, greater nodule diameter, and CYFRA21‐1 positive imply increased risk for triggering lung adenocarcinoma lesion. Therefore, high attention should be paid in the clinic to such SPN patients for early diagnosis and treatment.

Published: May 2022

Background. In patients with severe injury, predicting the injury site without using advanced diagnostic modalities can help formulate a diagnosis and treatment plan based on the suspected injury site. Objectives. This study aimed to determine the correlation between the injury site and trauma mechanism in severely injured patients with blunt trauma. Methods. We retrospectively analyzed the clinical characteristics—including age, sex, date of emergency room (ER) visit, time of injury, trauma mechanism (car accident, motorcycle accident, bicycle accident, pedestrian accident, fall, slipping and rolling down, crush injury, assault, and others), final diagnosis, injury severity score, abbreviated injury scale (AIS) score, and injury site—of 1,245 patients in a tertiary trauma center. Results. There was a strong correlation between certain injury sites and specific trauma mechanisms. In particular, most trauma mechanisms were associated with injury to the head and neck, as well as the chest, with a combined frequency of >40.0%. Moreover, when using one-way analysis of variance and Bonferroni’s post hoc tests, there were significant differences in AIS scores 1, 3, 4, and 5 for each trauma mechanism. Conclusion. Generally, when patients with severe injury present to the ER, the injury site can be predicted upon initial assessment based on the trauma mechanism. Based on our study, the injury site predicted by a specific mechanism should be checked repeatedly and additionally through physical examination and imaging tools. This can reduce misdiagnosis and help with accurate diagnosis and treatment.

Authors: Almutlaq Nourah , Eugster Erica A. , Nabhan Zeina , Donegan Diane
Published: May 2022

Background: Prolactinomas are rare in children and adolescents. As in adults, dopamine agonists (DAs) are the treatment of choice in the majority of patients. However, at what point children should be taken off of therapy and what the recurrence risk of hyperprolactinemia is following treatment withdrawal is not well described. Objective: Our objective was to systematically review our experience with DA treatment withdrawal in children and adolescents with prolactinomas. Methods: A retrospective review of patients followed for prolactinomas during the last 12 years was conducted. Variables analyzed included age, gender, initial serum prolactin levels, tumor characteristics, cabergoline dose, and results of treatment withdrawal. Clinical characteristics of patients who met eligibility criteria for DA withdrawal were compared with those who did not. Patients who underwent surgery were excluded. Results: Of 47 patients identified, 42 were included in the study. Of those, DA withdrawal was attempted in 13 (31%) and was initially successful in 3 (21%). Patients who did not meet eligibility criteria for treatment withdrawal had higher baseline prolactin levels (p = 0.018) as well as larger (p = 0.03) and more invasive (p = 0.002) tumors. Conclusions: Less than half of our patients were eligible for DA treatment withdrawal and less than one-fourth achieved remission of hyperprolactinemia following cessation of therapy. This suggests that the overall recurrence rate of prolactinomas in pediatric patients may be higher than has been reported in adults.

Published: May 2022

Background:

Sex differences in clinical characteristics and in-hospital outcomes among patients with non–ST-segment–elevation myocardial infarction have been described in Western countries, but whether these differences exist in China is unknown.

Methods:

We used a 2-stage random sampling design to create a nationally representative sample of patients admitted to 151 Chinese hospitals for non–ST-segment–elevation myocardial infarction in 2006, 2011, and 2015 and examined sex differences in clinical profiles, treatments, and in-hospital outcomes over this time. Multivariable logistic regression models adjusting for age or other potentially confounding clinical covariates were used to estimate these sex-specific differences.

Results:

Among 4611 patients, the proportion of women (39.8%) was unchanged between 2006 and 2015. Women were older with higher rates of hypertension, diabetes, and dyslipidemia. Among patients without contraindications, women were less likely to receive treatments than men, with significant differences for aspirin in 2015 (90.3% versus 93.9%) and for invasive strategy in 2011 (28.7% versus 45.7%) and 2015 (34.0% versus 48.4%). After adjusting for age, such differences in aspirin and invasive strategy in 2015 were not significant, but the difference in invasive strategy in 2011 persisted. The sex gaps in the use of invasive strategy did not narrow. From 2006 to 2015, a significant decrease in in-hospital mortality was observed in men (from 16.9% to 8.7%), but not in women (from 11.8% to 12.0%), with significant interaction between sex and study year (
P
=0.023). After adjustment, in-hospital mortality in women was significantly lower than men in 2006, but not in 2011 or 2015.

Conclusions:

Sex differences in cardiovascular risk factors and invasive strategy after non–ST-segment–elevation myocardial infarction were observed between 2011 and 2015 in China. Although sex gaps in in-hospital mortality were largely explained by age differences, efforts to narrow sex-related disparities in quality of care should remain a focus.

Emotions and Values in Practice: The Case of Elderly Care
Authors: Klausen Søren Harnow , Christiansen Regina , Emiliussen Jakob , Engelsen Søren
Published: May 2022

The moral and epistemic significance of emotions has been increasingly emphasized in recent philosophy. The focus has been mostly on metaethical questions. We add a new perspective by considering the practical importance of gauging, reacting to, enhancing, or reducing the emotions of others and oneself. We focus particularly on the collective aspect of emotion development and regulation, how emotions are entangled with values, and how they may be used constructively for handling otherwise difficult situations. We use the case of elderly care, drawing on a qualitative study from a Danish municipality, to illustrate the complex and multifarious ways in which emotions shape the normative landscape in which attempts to maintain or improve well-being take place.

Research on distributed beamforming synchronization technology in inter-satellite link system
Authors: Chen Jianyun , Yonggang Zhang , Liu Sili
Published: May 2022

Limited by satellite load and carrying capacity, it is difficult for inter-satellite link systems to improve information transmission capabilities by increasing power and antenna size like traditional terrestrial communication systems. Satellite communication payload power has always been an important limitation of long-distance communication performance. In order to improve the satellite’s long-distance communication capability and comprehensively consider the characteristics of Doppler frequency changes in the satellite environment, we propose a cooperative communication algorithm based on weak bit feedback. This algorithm can realize the time and space focusing of the beams emitted by multiple distributed satellite nodes at the destination node, and improve the performance of satellite long-distance communication. This paper simulates the above algorithm based on STK/Matlab software. The simulation results show that the weak bit feedback algorithm has stronger adaptability, faster convergence speed and higher synthesis efficiency under different channel changes. The algorithm is simple and easy to implement, and is suitable for the inter-satellite link environment with many satellite nodes and high scalability. Finally, we conducted hardware experimental verification, analyzed the signal flow of each module in the hardware, and tested it on the USRP software radio platform. The test results show that it is a feasible solution to realize distributed satellite node cooperative communication based on the weak bit feedback algorithm.
Effects of the moisture barrier and thermal liner components on the heat strain and thermal protective performance of firefighter turnout systems
Authors: Gao Huipu , Deaton A Shawn , Barker Roger , Fang Xiaomeng , Watson Kyle
Published: May 2022

An ideal firefighter turnout system should be capable of releasing body heat to prevent heat stress, indicated by THL (total heat loss) and Ref (evaporative resistance) indexes, while maintaining high thermal protective performance (TPP). Our study found no correlations between THL and Ref, or between Ref and TPP. The results showed that, when tested in the mild condition as in the standard THL test method, turnout systems with bi-component moisture barriers exhibited an advantage in THL that did not translate to more thermally stressful hot environments. A physiological manikin was used to understand the effect of turnout clothing systems on heat strain in different environmental conditions and the value of utilizing Ref or THL to predict heat strain performance. We found no difference in heat strain performance between composites with one-layer and two-layer spunlace thermal liners in mild or hot conditions. It showed that both THL and Ref had their limitations: THL only predicted thermal burden in mild environments, while Ref was only correlated in hot conditions. Thus, the exclusive reliance on either index could increase the risk of heat stress, and we recommend incorporating the Ref heat strain index, along with THL, as dual metrics for certifying the heat strain performance of turnout suits in the NFPA 1971 standard.

Objective

To examine factors associated with hospital safety net burden and its impact on survival for patients with sinonasal squamous cell carcinoma (SNSCC).

Study Design

Retrospective database study.

Setting

National Cancer Database from 2004 to 2016.

Methods

SNSCC cases were identified in the National Cancer Database. Hospital safety net burden was defined by percentage of uninsured/Medicaid patients treated, namely ≤25% for low‐burden hospitals, 26% to 75% for medium‐burden hospitals, and >75% for high‐burden hospitals (HBHs). Univariate and multivariate analyses were used to investigate patient demographics, clinical characteristics, and overall survival.

Results

An overall 6556 SNSCC cases were identified, with 1807 (27.6%) patients treated at low‐burden hospitals, 3314 (50.5%) at medium‐burden hospitals, and 1435 (21.9%) at HBHs. On multivariate analysis, Black race (odds ratio [OR], 1.39; 95% CI, 1.028‐1.868), maxillary sinus primary site (OR, 1.31; 95% CI, 1.036‐1.643), treatment at an academic/research program (OR, 20.63; 95% CI, 8.868‐47.980), and treatment at a higher‐volume facility (P < .001) resulted in increased odds of being treated at HBHs. Patients with grade III/IV tumor (OR, 0.70; 95% CI, 0.513‐0.949), higher income (P < .05), or treatment modalities other than surgery alone (P < .05) had lower odds. Survival analysis showed that hospital safety net burden status was not significantly associated with overall survival (log‐rank P = .727).

Conclusion

In patients with SNSCC, certain clinicopathologic factors, including Black race, lower income, treatment at an academic/research program, and treatment at facilities in the West region, were associated with treatment at HBHs. Hospital safety net burden status was not associated with differences in overall survival.

Introduction: Neoliberalism in the Americas. Brutal experiments, distressful realities, and conspicuous contestations
Authors: Altheman Eduardo , González García Mónica , Martínez Ximena
Published: May 2022

This special issue was originally conceived as a conference organized at Duke University in January 2019, entitled “Neoliberalism in the Americas: Brutal Experiments, Distressful Realities, and Conspicuous Contestations. Re-thinking the South in the North and the North in the South.” The premise that inspired this reunion was, since Milton Friedman used dictatorial Chile as a laboratory for his monetary theories, neoliberalism has always been a matter that concerned the Americas as a continent. It has bound together Chicago and Santiago in one single package of authoritarian rule and unfettered capitalism, blemished with Nobel prizes, wealth concentration, and always-renewed, never-fulfilled promises of freedom and economic growth. Most of the articles were originally presented at the aforementioned conference, including a piece shared by one of the keynote speakers, Brazilian philosopher Vladimir Safatle. Nonetheless, we have also incorporated other contributions, such as an interview with Australian scholar Melinda Cooper. These works address neoliberalism from literature to psychoanalysis, from politics to gender and sexual identities, from historical and present-day investigations. The result is a multinational, transdisciplinary volume centered on the experiments of neoliberalization which, since the 1970s, connect the entire continent—ultimately reaching the extent of a truly global experience.

In this article, we present ideas about developing innovative methods for the sociology of futures. Our approach brings together the literature on sociotechnical imaginaries and the sociology of futures with vital materialism theories and research-creation methods. We draw on our research-creation materials from a series of online workshops. The workshops involved the use of creative writing prompts with participants across a diverse range of age groups and locations. The article ends with some reflections on the implications of our approach for researching the futures of emerging digital technologies and the methodological and theoretical development of the sociology of futures.
Social workers’ experiences in integrated health care during the COVID-19 pandemic
Authors: Weng Suzie S
Published: May 2022

The massive spread of the novel COVID-19 virus across the globe has been disruptive to all providers within integrated healthcare systems, including social workers. The literature on how the pandemic has impacted medical workers are emerging. The present article explored the experiences of social workers. A purposive sample of 40 social workers in integrated healthcare settings was interviewed from September to November 2020 prior to vaccine availability to learn about how they managed the earlier months of the pandemic. A constant comparison approach was used to analyze the data.

Themes identified included: (1) how social workers felt about safety in their work environments; (2) what it was like for social workers to transition to remote work; (3) how the pandemic affected social workers’ workload and mental health; and (4) what were the preparedness issues and lessons learned.

This study adds to the existing literature on provider experiences of the pandemic in integrated health care with social workers’ voices. This additional perspective may contribute to better preparedness of behavioral health services and taking care of social workers in future crises.
