Occupational Therapy Research in Schools: A Mapping Review
Authors: de Oliveira Borba Patrícia L. , Pereira Beatriz P. , de Souza Joana R. B. , Lopes Roseli E.
Published: August 2020

Background. Throughout the world, schools have become an important place for professional integration for occupational therapists. Objective. To map the production of knowledge on research related to the keywords “occupational therapy” and “school.” Method. A mapping review was performed, searching the terms “occupational therapy” and “school” in the Scopus and Web of Science databases. The data were used to construct a descriptive map of the production of knowledge about occupational therapy and school. The following data were categorized and extracted: years of publication, journals of publication, authors’ and coauthors’ countries, descriptors, informant population, beneficiary population, place of research, and occupational therapy propositions. Results. It included 127 research articles covering from 1988 to 2017. This has been a scientific field under construction for at least 30 years, largely centralized in the United States of America, mostly dedicated to children, and focused on disabilities, with an emphasis on rehabilitation through descriptions and analyses of interventions for individuals or, when it was for groups, with the final goal of benefitting individuals with disabilities. Implications. Examining the existing scientific production invites us to reflect on whether the dominant focus in this field has responded to the contemporary problems of schools.
Jejunal Polyps out of Place: A Case of Gastric Heterotopia of the Jejunum
Authors: Urquhart Siri A. , Coelho-Prabhu Nayantara
Published: August 2020

Heterotopia is the presence of normal physiologic tissue in an atypical location. Gastric heterotopia has been described in various locations throughout the gastrointestinal tract, including the small intestine. Gastric heterotopia of the small intestine typically is asymptomatic but may present in several ways with symptoms of obstruction, bleeding, perforation, intussusception, or pain. However, gastric heterotopia is rare beyond the duodenum except for its frequent association with Meckel’s diverticulum. This entity should be considered in the differential diagnosis of polypoid lesions presenting with symptoms of bleeding or obstruction especially in younger patients. We present a case of gastric heterotopia of the jejunum in a patient with a prior history of Meckel’s diverticulectomy after he presented with obstructive symptoms. His symptoms improved following resection of two jejunal polyps via antegrade double-balloon assisted enteroscopy with fluoroscopy. On histopathlogical examination, findings were consistent with gastric heterotopia. This case highlights the importance of considering gastric heterotopia in the differential diagnosis of polypoid lesions located beyond the ligament of Treitz in younger patients presenting with obstructive symptoms.

Published: August 2020

Chronic cholecystitis or symptomatic gallbladder is a prolonged mechanical or functional disorder of abnormal gallbladder emptying. Most of the patients have recurrent pain attacks (acute biliary colic), but when pain lasts more than 24 hours, it requires urgent surgical intervention (acute cholecystitis). The length of a fully distended gallbladder is about 7 to 10 cm. We report a case of a huge and severely inflamed gallbladder, as we have just found only a few previous case reports of the huge gallbladder in the literature. This case report and review may help to find a mechanism for the development of a giant gallbladder. The patient was a 36-year-old woman, who had been known to have a symptomatic gallstone for at least three years. The patient underwent laparotomy, and a giant 22 cm roundish severely inflamed and overdistended gallbladder with wall thickening and tight adhesion to adjacent organs was found under the right liver lobe. Femininity and diabetes seem to be risk factors for developing a huge gallbladder, and several hypotheses are encountered: (1) a long-lasting obstructed cystic duct or biliary tree, and accumulation of mucosal secretion from the gallbladder epithelium, (2) an obstructed hepatic/cystic duct junction with a stone acting like a check valve and bile trapping mechanism, and (3) gallbladder dysfunction and cholecystoparesis affecting through reduced cholecystokinin and celiac parasympathetic nerve disturbance in diabetes and diabetic autonomic neuropathy. Open cholecystectomy is the technique of choice in surgical excision of a huge gallbladder; however, laparoscopy could be performed by expert hands.
Range-Based Positioning with Self-Adapting Fireworks Algorithm for Wireless Sensor Networks
Authors: Huang Meigen , Yu Bin
Published: August 2020

Positioning is the basic function of wireless sensor networks (WSN). At present, range-based positioning is a common method to obtain the position of a node, but its accuracy has encountered a bottleneck. The fundamental reason is that it ignores the ranging information between blind nodes. Therefore, based on the design of the positioning optimization factor to adjust the weight of the ranging information between the blind nodes, the positioning model of minimizing the error is established. On the basis of designing the blind node positioning matrix, the multiblind node localization problem is transformed into a single-objective optimization task, and the model also supports two-dimensional and three-dimensional positioning. In order to solve the model efficiently, we added a self-adaptive function that matches the positioning requirements for the explosion search mechanism of the fireworks algorithm (FWA) and then proposed a self-adaptive FWA (SA-FWA). The experimental results on the real ranging dataset show that the model has higher accuracy than other methods and achieves the current optimal positioning error, which is 1.88 m for received signal strength data and 1.02 m for time of arrival information, respectively.

Lung Cancer and Immunity Markers
Authors: Lim Raymond J. , Liu Bin , Krysan Kostyantyn , Dubinett Steven M.
Published: August 2020

An in-depth understanding of lung cancer biology and mechanisms of tumor progression has facilitated significant advances in the treatment of lung cancer. There remains a pressing need for the development of innovative approaches to detect and intercept lung cancer at its earliest stage of development. Recent advances in genomics, computational biology, and innovative technologies offer unique opportunities to identify the immune landscape in the tumor microenvironment associated with early-stage lung carcinogenesis, and provide further insight in the mechanism of lung cancer evolution. This review will highlight the concept of immunoediting and focus on recent studies assessing immune changes and biomarkers in pulmonary premalignancy and early-stage non–small cell lung cancer. A protumor immune response hallmarked by an increase in checkpoint inhibition and inhibitory immune cells and a simultaneous reduction in antitumor immune response have been correlated with tumor progression. The potential systemic biomarkers associated with early lung cancer will be highlighted along with current clinical efforts for lung cancer interception. Research focusing on the development of novel strategies for cancer interception prior to the progression to advanced stages will potentially lead to a paradigm shift in the treatment of lung cancer and have a major impact on clinical outcomes.

A Novel Gain-of-Function KCND3 Variant Associated with Brugada Syndrome
Authors: Li Xianqing , Li Zongzhe , Wang Dao Wen Wen , Wang Dao Wu , Wang Yan
Published: August 2020

Brugada syndrome (BrS) is a known cause of sudden cardiac death (SCD) characterized by abnormal electrocardiograms and fatal arrhythmias. The variants in KCND3 encoding the KV4.3 potassium-channel (the α-subunit of the Ito) have seldom been reported in BrS. This study aimed to identify novel KCND3 variants associated with BrS and elucidate BrS pathogenesis. High-depth targeted sequencing was performed and the electrophysiological properties of the variants were detected by whole-cell patch-clamp methods in a cultured-cell expressing system. The transcriptional levels of KV4.3 in different genotypes were studied by real-time PCR. Western blot was used to assess channel protein expression. A novel KCND3heterozygous variant, c.1292G>A (Arg431His, R431H), was found in the proband. Whole-cell patch-clamp results revealed a gain-of-function phenotype in the variant, with peak Ito current density increased and faster recovery from inactivation. The expression of mutant Kv4.3 membrane protein increased and the cytoplasmic protein decreased, demonstrating that the membrane/cytoplasm ratio was significantly different. In conclusion, a novel KCND3 heterozygous variant was associated with BrS. The increased Ito current explained the critical role of KCND3 in the pathogenesis of BrS. Genetic screening for KCND3 could be useful for understanding the pathogenesis of BrS and providing effective risk stratification in the clinic.

Background: The COVID-19 pandemic has caused disruption of routine gastroenterology practice, which has resulted in the suspension of elective endoscopic procedures and outpatient consults. For the past months, the strategy was to mitigate infection risk for the healthcare team while still providing essential service to patients. Prolonged suspension of the outpatient clinics and endoscopy practice, however, is deemed unsustainable and could even be detrimental. It can compromise patient care and result in poor outcomes; hence, a well-crafted plan is needed for the gradual resumption of clinic operations and endoscopic procedures. Summary: As the world begins to transition to the “new normal,” there are new health and safety issues to consider. Adaptive measures like telemedicine and electronic health records should be utilized to facilitate patient care while minimizing exposure. Careful patient screening, adequate supply of personal protective equipment, effective infection-control policies, as well as appropriate administrative modifications are needed for a safe return of gastroenterology practice. Key Messages: Ensuring the safety of patients, caregivers, and healthcare workers should remain as top priority. To help ease the transition as we move forward from this pandemic, we present a review of recommendations to guide gastroenterologists and endoscopy unit administrators in the gradual return to gastroenterology practice.

Podcast e radiojornalismo
Authors: Ferraz Nivaldo , Gambaro Daniel
Published: August 2020

O artigo relaciona a formação histórica do radiojornalismo com o podcast, apontando que características institucionalizadas se prolongam em novas práticas, e quais devem ser repensadas. O rádio brasileiro valoriza o modelo “hard news”, com cobertura ao vivo, vozes de especialistas e entrevistas apoiadas por pautas apressadas, causa e consequência da insignificante presença de modos mais elaborados de produção. Já plataformas assíncronas como o podcast caracterizam nova Experiência Midiatizada de Escuta, decorrência das “estruturas de sentimento” contemporâneas, determinadas pela mediação tecnológica de práticas cotidianas e por relações emergentes de representatividade, impondo uma nova lógica de consumo de notícia. Escolhemos o podcast Vozes: histórias e reflexões, da CBN, como exemplo para um modelo que mantém a tradição jornalístico-radiofônica de reportagens especiais, enquanto quebra o paradigma estabelecido e propõe uma nova ordem de produção e provocação de consumo.

In this spirit, after the IAMCR Conference 2019 held in Madrid, Spain, the idea arose to publish some of the research papers by members of the working group that dealt with the themes of the dossier.
Cine familiar y emigración
Authors: Neira Fernando Redondo
Published: August 2020

El cine familiar constituye una muy reveladora herramienta para indagar en el conocimiento visual de un pasado íntimo y personal, útil para la reconstrucción de usos y costumbres que ayuden a comprender la evolución de las sociedades contemporáneas. Nuestro trabajo se basa en la consideración del emplazamiento nuclear que este cine ocupa en el universo audiovisual del siglo XX, tal como asegura Patricia Zimmerman. Para esta autora, la singularidad de estas películas está en que son los propios espectadores quienes se hacen cargo de los mecanismos audiovisuales. Nos proponemos el análisis de una pieza audiovisual que permita abordar en toda su complejidad un fenómeno histórico-social muy concreto: la emigración española en la segunda mitad del siglo XX y cómo, en ella, se gestionó la memoria familiar o la reconstrucción del pasado a través de la imagen.

Published: August 2020

Estudiamos el rol de los prosumidores de imágenes en el contexto de las manifestaciones venezolanas entre 2014 y 2018, años de alta confrontación en los cuales circularon imágenes que desafiaron al gobierno y sus controles. Nos referimos a ellas con la categoría de “fotografías incómodas” debido a su confrontación directa al poder y a las interrogantes que plantean por su contenido violento, indignante y perturbador. A partir de la revisión documental y la consulta a expertos analizamos estas fotografías y trazamos una ruta en la que indagamos la pertinencia de su difusión masiva y reflexionamos sobre su impacto, teniendo como referencia las ideas de George Didi-Huberman, Joan Fontcuberta, Manuel Castells y Guy Debord.
Visual hybridizations in two audiovisual productions
Authors: Faquin César Biégas , Araujo Denize
Published: August 2020

This paper aims to analyze and discuss two films that present hybrid aesthetics: Lars von Trier’s Dogville (2003) and Welchman´s and Kobiela´s Loving Vincent ( 2017). Dogville evokes the theatre language in its construction and develops an intertextual relationship by using Brecht’s epic theatre, while Loving Vincent is a tribute film to Vincent van Gogh, essentially intertextual because it is based on letters that van Gogh once wrote, as well as his own works of art. The theoretical frame of reference on the processes of dialogism, polyphony, hybridization, intermediality and intertextuality is provided by Araujo, Bazin, Bakhtin, Brecht, Kristeva, Metz, Muller, Nagib e Rajewski.

Published: August 2020

Objective:

The risk of thrombosis in myeloproliferative neoplasms, such as primary myelofibrosis varies depending on the type of key driving mutation (JAK2 [janus kinase 2], CALR [calreticulin], and MPL [myeloproliferative leukemia protein or thrombopoietin receptor]) and the accompanying mutations in other genes. In the current study, we sought to examine the propensity for thrombosis, as well as platelet activation properties in a mouse model of primary myelofibrosis induced by JAK2
V617F
(janus kinase 2 with valine to phenylalanine substitution on codon 617) mutation.

Approach and Results:

Vav1-hJAK2
V617F
transgenic mice show hallmarks of primary myelofibrosis, including significant megakaryocytosis and bone marrow fibrosis, with a moderate increase in red blood cells and platelet number. This mouse model was used to study responses to 2 models of vascular injury and to investigate platelet properties. Platelets derived from the mutated mice have reduced aggregation in response to collagen, reduced thrombus formation and thrombus size, as demonstrated using laser-induced or FeCl
3
-induced vascular injury models, and increased bleeding time. Strikingly, the mutated platelets had a significantly reduced number of dense granules, which could explain impaired ADP secretion upon platelet activation, and a diminished second wave of activation.

Conclusions:

Together, our study highlights for the first time the influence of a hyperactive JAK2 on platelet activation-induced ADP secretion and dense granule homeostasis, with consequent effects on platelet activation properties.
Conflicting Perspectives on the Value of Neprilysin Inhibition in Heart Failure Revealed During Development of a Decision Aid Focusing on Patient Costs for Sacubitril/Valsartan
Authors: Venechuk Grace E. , Allen Larry A. , Doermann Byrd Katherine , Dickert Neal , Matlock Daniel D.
Published: August 2020

Background:

Despite concerns about rising costs in health care, cost is rarely an issue discussed by patients and clinicians when making treatment decisions in a clinical setting. This study aimed to understand stakeholder perspectives on a patient decision aid (PtDA) meant to help patients with heart failure choose between a generic and relatively low-cost heart failure medication (ACE [angiotensin-converting enzyme] inhibitor or angiotensin II receptor blocker) and a newer, but more expensive, heart failure medication (angiotensin II receptor blocker neprilysin inhibitor).

Methods and Results:

Feedback on the PtDA was solicited from 26 stakeholders including patients, clinicians, and the manufacturer. Feedback was recorded and discussed among development team members until consensus regarding both the interpretation of the data and the appropriate changes to the PtDA was reached. Stakeholders found the PtDA sufficient in clarifying the different treatment options for heart failure. However, patients, physicians, and the manufacturer had different opinions on the importance of highlighting cost in a PtDA. Patients indicated issues of cost were crucial to the decision while physicians and manufacturers expressed that the cost issue was secondary and should be de-emphasized.

Conclusions:

The stratified perspectives on the role of cost in medical decision-making expressed by our participants underscore the importance and challenge of having clear, frank discussions during clinic visits about treatment cost and perceived value.
Excimer Laser Sheath–Assisted Retrieval of “Closed‐Cell” Design Inferior Vena Cava Filters
Authors: Desai Kush R. , Xiao Nicholas , Salem Riad , Karp Jennifer K. , Ryu Robert K. , Lewandowski Robert J.
Published: August 2020

Background

Numerous reports have shown that inferior vena cava filters are associated with clinically significant adverse events. Complicating factors, such as caval incorporation, may lead to technical challenges at retrieval. The use of advanced techniques including the laser sheath have increased technical success rates; however, the data are limited on which filter types necessitate and benefit from its use.

Methods and Results

From October 2011 to September 2019, patients with inferior vena cava filter dwell times >6 months or with prior failed retrievals were considered for laser sheath–assisted retrieval. Standard and nonlaser advanced retrieval techniques were attempted first; if the filter could not be safely or successfully detached from the caval wall using these techniques, the laser sheath was used. Technical success, filter type, necessity for laser sheath application based on “open” versus “closed‐cell” filter design, dwell times, and adverse events were evaluated. A total of 441 patients (216 men; mean age, 54 years) were encountered. Mean dwell times for all filters was 56.6 months, 54.4 among closed‐cell filters and 58.5 among open‐cell filters (
P
=0.63). Technical success of retrieval was 98%, with the laser sheath required in 143 cases (40%). Successful retrieval of closed‐cell filters required laser sheath assistance in 60% of cases as compared with 7% of open‐cell filters (odds ratio, 20.1;
P
<0.01). In closed‐cell inferior vena cava filters, dwell time was significantly associated with need for laser, requiring it in 64% of retrievals with dwell times >6 months (
P
=0.01). One major adverse event occurred among laser sheath retrievals when a patient required a 2‐day inpatient admission for a femoral access site hemorrhage.

Conclusions

Closed‐cell filters may necessitate the use of the laser sheath for higher rates of successful and safe retrieval.

Authors: Yang Xiaojiao , Li Jun , Liu Ying
Published: August 2020

One-dimensional gold nanofibers are good candidates for next generation nanoelectronic devices. Here, gold nanofibers were synthesized via electrospinning with subsequent in-situ thermal reduction. The thermal behavior of the precursor nanofibers was investigated by thermogravimetric/differential
thermal analysis and fourier transform infrared. The polymer parts are decomposed and removed step by step, meanwhile, gold salt is decomposed and in-situ reduced to form gold nanoparticles in air without any reducing agent or gas due to its strong oxidation ability. The effects of
gold content, polymers type (PVP, PVA, PAN), calcination atmospheres (Air, H2, H2/Ar) and temperatures (200 °C to 500 °C) on the morphology and structures of gold nanofibers were characterized by XRD, SEM, and TEM. The results shows that PVP is the optimal polymer
with the gold content of 6:1 (PVP:Au) to fabricate the continuous gold nanofibers with good morphology and structures. The final gold nanofibers with average diameter of 60 nm and several hundred micrometers long, were fabricated after calcined at 500 °C in air for 2 hours. It was composed
of gold nanoparticles that ranged from 5 to 30 nm.
Antimicrobial Properties of Levofloxacin Antibiotic Complexes of Zirconium(IV) and Indium(III)
Authors: Alnuwaiser Maha Abdallah
Published: August 2020

In this article, there are two new levofloxacin (HLevo) complexes were synthesized and spectroscopically discussed. These complexes were prepared in alkaline state (pH = 8) with the 1:1 stoichiometry between zirconyl(II) or indium(III) chloride and pure HLevo antibiotic drug ligand
in mixed solvent equal volumes from methanol and bi-distilled water. The structures interpretation were performed based on the micro analytical (elemental analyses), molar conductance and spectroscopic measurements. It is shown that the deprotonated HLevochelate was coordinated towards ZrIV
and InIII metal ions, this occurs as a bidentate ligand through the oxygen atoms of carboxylate and carbonyl group, respectively. Accordingly, these complexes can be speculated as [ZrO(Lev)(Cl)(H2O)] · H2O (1) and [In(Lev)(Cl)2(H2O)2]
(2). Through Tranmission Electron Microscopy (TEM) imaging it is demonstrated that the nanoscale particles have a homogeneous distribution across the complex surface. Furthermore, by assessing in vitro antimicrobial activities, the inhibition activity of HLevo drug ligand as well as
the associated metal ion complexes were evaluated towards specific types of bacteria and fungi.

In this paper, we mainly study the change of concrete quality and law of mechanical change under acid-rain environment, we adopt periodic immersion method to make statistics of concrete samples in different periods. In the process of experimental design, we need to prepare raw materials,
choose the appropriate mixing scheme of concrete materials, prepare materials, make testing samples, simulate the acid-rain environment; we analyze the corrosion principle of concrete samples, in different period, sample weight measurement, compressive strength measurement and tensile strength
measurement are done mainly by periodic immersion method, we need to design a clear calculation method. In the steps of experimental results and analysis, XRD and SEM are adopted to analyze the morphology of concrete specimen, in order to compare the influence of acid-rain environment on concrete
samples, we set different pH of acid-rain environment (1.2, 2.5 and 4.5, respectively), we find that with the increase of soaking time, a large number of holes appear on the surface of concrete samples, at the same time, the lower the pH is, the larger the pore size of these small holes will
be; we analyze the quality of concrete samples, and adjust the pH of sample, soak for 90 days respectively, every 10 days can be taken as an observation time point, we find that the quality of concrete samples shows a downward trend as a whole, at the same time, the smaller the pH is, the
faster the mass declines; we test the compressive strength of concrete samples and tensile strength of concrete samples, find that with the increase of pH, the compressive strength of concrete samples and tensile strength of concrete samples show the trend of first increasing-then decreasing.

Authors: Choi Hyeokjoo , Choi Chiwon , Kwon Seok Hun , Park Young , Choi Wonseok
Published: August 2020

Materials with low adhesion have a limited range of applications. To solve this problem, the stress can be alleviated by inserting an interlayer between the substrate and the semiconductor material. As such, the adhesion can also be improved by depositing an interlayer between the carbon
nanowall (CNW) with a low adhesive force and the substrate. In this study, indium tin oxide (ITO), whose thickness was controlled via radio frequency (RF) magnetron sputtering on the substrate, was used as an interlayer, and CNWs were grown using microwaveplasma-enhanced chemical vapor deposition
(MPECVD) with a mixture of methane (CH4) and hydrogen (H2) gases. To confirm the adhesion between the CNWs and the substrate according to the thickness of the ITO interlayer, the dissociation of the CNWs was confirmed using an ultrasonic washing machine. Hall measurement
was used to investigate the electrical properties. Afterwards, to analyze the change in the surface structure, contact angle analysis and field emission scanning electron microscopy (FESEM) analysis performed.

encapsulate bio-inert gases to prepare nano-scale microbubbles NBs. Meanwhile, the Annexin V molecules were connected through the conjugation of biotin-avidin to prepare targeted nano-scale ultrasound contrast agents (UCAs) Annexin V-Nanobubbles (AVNBs). The tumor-bearing mice apoptosis models
were constructed by injecting human breast cancer MDA-MB231 cells, and the nano-scale UCA AV-NBs was used for ultrasound diagnosis, data collection, and statistical analysis. The results showed that the prepared AV-NBs were nano-sized hollow spheres with relatively stable particle size, zeta
potential, and excellent stability. By verifying the constructed mice apoptosis models, it was found that mice heterotopic transplantation tumor apoptosis models were successfully constructed. When the mice models were observed by ultrasound, the apoptosis index of the cell was found to be
positively correlated with the enhancement degree of the image. Therefore, the enhancement effect of the targeted UCA AV-NBs was obvious. The AV-NBs could be specifically targeted to the apoptotic region of tumor tissue in vivo, which was also slightly enriched in the liver and kidney.
Therefore, the experiment found that the targeted nano-scale UCA AV-NBs combined with ultrasound detection could significantly enhance the diagnostic accuracy of breast cancer tumors, which provided the experimental evidence for early tumor diagnosis and evaluation.

In this paper a novel PEMFC voltage model considering the leakage current is established. Numerical simulation results based on the newly established PEMFC model is compared with the experimental results and indicates that they have a good match with the experimental results. Based
on the proposed voltage model and previous studies, the PEMFC ecological criterion was proposed and derived. As well, other finite time thermodynamics objective functions including entropy yield, ecological objective function and ecological performance coefficient formula are derived for PEMFCs.
Detailed numerical simulations are performed considering different design parameters and operating parameters. Ecological performance of an irreversible PEMFC is gained and such results can be further used for ecological optimization to yield maximum performance of the PEMFC.

A laboratory-experimental and theoretical-modeling investigation was conducted of isobaric, radiative cooling of cloud-like water mists to a remote heat sink, similar to what can happen at the tops of clouds. For mist initially at 20°C cooled by a radiative sink at −20°C, the mean (D43) mist droplet diameter grew from 5.5 to 8.4 μm and the mist temperature decreased from 20° to 3°C in just 80 s. Modeling showed that conventional assumptions were able to predict the measured temperature decrease reasonably well but not droplet size changes, suggesting that bulk radiative cooling was being reasonably well modeled but not detailed, droplet-size-dependent behavior. In a theoretical analysis, Lewis-number near unity was exploited to obtain an analytic expression for quasi-steady supersaturation that agrees with what Davies reported in 1985 but is simpler and is a function of only droplet size distribution, surface tension, and solute parameters and not radiative transfer. A simpler expression for the corresponding time constant was also found that is a function of only the binary diffusion coefficient and D31 moment of the droplet diameter distribution. The time constant was found to be in milliseconds and not seconds. Simply modifying quasi-steady supersaturation (i.e., applying droplet cooling effects uniformly to all droplet sizes) was shown not to be an acceptable substitute for including droplet-specific radiation terms in the droplet growth equation. These results confirm that radiative cooling at cloud top can have a significant effect on droplet size evolution and temperature change and provide data and analytical simplifications for use in further needed investigations of radiation modeling assumptions and parameterizations.

The development of tropical cloud clusters (TCCs) to tropical cyclones (TCs) is the process of TC formation. This study identifies five main environmental transitions for the development of TCCs to TCs in the western North Pacific by using a cluster analysis method. Of these, three transitions indicate TCCs that develop in monsoon environments and two in easterly environments. Their numbers, distributions, and interannual variability differ. On average, the development time, defined as the period from the TCC forming to it developing into a TC, for TCCs that develop in easterly environments is shorter than that in monsoon environments. For the development of TCC to TC in easterly environments, TCCs have fewer embedded mesoscale convective systems (MCSs), which are located closer to the TCC center. Moreover, there is a stronger inward short-term (less than 10 days) angular momentum flux (AMF) at middle levels (800–500 hPa) before TCC formation. Conversely, in monsoon environments, TCCs have more MCSs, which are located farther from the TCC center. A stronger inward short-term AMF at low levels (1000–850 hPa) is observed before TCC formation and develops upward during the development of TCC to TC. The characteristics of MCS and AMF are significantly correlated with the development time of TCC to TC. In summary, large-scale easterly and monsoon environments cause TCCs to have different MCS and AMF characteristics, leading to higher efficiency for TCCs developing into TCs in easterly environments compared to monsoon environments.
Biodebridement in the Surgical Intensive Care Unit: Unique Therapy for Unique Patients

Published: August 2020

Acute care surgery has evolved to encompass the advanced management of complex nonhealing wounds. Biodebridement has the potential to improve the care of chronic wounds for acute care surgery patients, particularly for patients in the surgical intensive care unit (SICU) with hospital-acquired pressure injuries. A case report of biodebridement using larval maggot therapy in the SICU is presented to illustrate real-world application and progression in wound healing. A review of current research involving biodebridement was conducted. A septuagenarian gentleman sustained a fall resulting in cervical spine fractures with neurological deficits. The patient had a prolonged hospital course in the SICU, complicated by myocardial infarction, respiratory failure requiring tracheostomy, and development of a Stage IV sacral pressure ulcer. The wound base was sharply debrided several times and became refractory to conventional mechanical/chemical debridement techniques. The patient had a prohibitively high risk for the operating room but remained too sensate for further effective bedside debridement. Biodebridement was utilized to create a viable wound base, with improved appearance noted within 2 weeks. A review of the current literature shows biodebridement has numerous benefits in the management of chronic wounds. Biodebridement is a unique therapy that possesses great value for select patients in the SICU. In particular, patients who are too high risk for further operative intervention, but too sensate for ongoing bedside debridement and dressing changes, benefit significantly from this underutilized approach. Further research is needed to solidify the place of biodebridement in the surgical management of chronic nonhealing wounds.
Epithelioid Sarcoma of the Tongue: An Unusual Tumor Mimic for Squamous Cell Carcinoma

Published: August 2020

Introduction:

Epithelioid sarcoma is a rare soft tissue malignancy that usually presents in the distal extremities along fascial planes, aponeuroses or tendon sheaths. Very rarely, it presents as a primary or metastatic lesion of the head neck.

Methods:

Chart review and comprehensive literature review using PubMed and Google Scholar.

Results:

A 17-year-old non-smoker was referred for evaluation of an ulcerative lesion of the right anterior-lateral tongue, progressing over several months. Incisional biopsy was concerning for squamous cell carcinoma. He underwent partial glossectomy and bilateral selective neck dissections, with reconstruction using a radial forearm free flap. Final pathology was consistent with epithelioid sarcoma, proximal type, demonstrating perineural invasion and close margins. Post-operative PET scan showed no persistent nor metastatic disease. He underwent post-operative radiation therapy to a total dose of 56 Gy to the primary site.

Conclusion:

Epithelioid sarcoma is a rare malignancy usually presenting in the extremities of young adults, which uncommonly presents in the head and neck as a primary or metastatic lesion. The infrequency of these lesions has prevented development of evidence-based treatment recommendations. As with most sarcomas, surgery is the mainstay of therapy for epithelioid sarcoma, while radiation has been used in an adjunctive role. Although a rare lesion, epithelioid sarcoma should be considered in the differential diagnosis for atypical epithelioid lesions of the tongue and oral cavity when patient demographics, gross lesion characteristics, or histopathology are not entirely consistent with more common lesions, such as squamous cell carcinoma.
Caring for the Poor and Vulnerable: A Virtue Analysis of Mandated Health Insurance Compared with Healthcare Sharing Ministries
Authors: Sullivan Ezra
Published: August 2020

In the present time, what has been called the “medical–industrial insurance complex” in the United States needs reform. As health insurance in the United States remains inaccessible to millions of people, and as prices continue to rise, questions arise about the most moral ways to ensure delivery of health care especially to the most vulnerable populations. In this essay, I offer a virtue analysis of the moral implications of health insurance mandated by the US Government in contrast to an increasingly popular alternative to insurance, namely, healthcare sharing ministries. In part 1, I list some of the moral problems entangled with US Government-mandated health insurance, including injustice, disrespect for patient autonomy, limitations on patient freedom, exploitation of patients for profit, undermining of conscience rights, cooperation with evil, and scandal. In part 2, I discuss the issue of risk and then list some potential moral advantages to healthcare ministries, including respect for patient autonomy, conscience, and the religious freedom to witness to the Catholic faith in charity and solidarity.

Mandated health insurance the United States presents some moral challenges for conscientious Catholics, whereas healthcare sharing ministries appear to ameliorate some of these issues. Ultimately, the individual should have freedom to choose either insurance or healthcare sharing, given the different benefits and risks entailed by both.

A systematic review and meta-analysis was conducted to comprehensively examine the association between Dietary Inflammatory Index (DII®) score and risk of frailty. Frailty risk were available from five studies comprising 13,908 older adults. Furthermore, frailty related parameters were extacted from two studies with 7,539 individuals. A pooled adjusted odds ratio analysis indicated that there was an association between DII® score and frailty risk (OR = 1.24, 95%CI: 1.6–1.33, P < 0.001, I2 = 0.0%). The results of frailty related parameters demonstrated that DII® score was associated with weakness risk (OR = 1.12, 95%CI: 1.05–1.19, P = 0.014, I2 = 0.0%), but not other frailty-related parameters including exhaustion, low BMI or low physical activity. The results of this meta-analysis suggest that older adults who exhibit higher DII® scores have an increased frailty risk. Further prospective cohort studies with longer follow-up periods, are needed to support this possible association between DII® score and frailty risk.
