Authors: Champagne Pierre-Olivier , McDowell Michael M. , Wang Eric W. , Snyderman Carl H. , Zenonos Georgios A. , Gardner Paul A.
Published: December 2020

OBJECTIVE

During the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, endoscopic endonasal surgery (EES) is feared to be a high-risk procedure for the transmission of coronavirus disease 2019 (COVID-19). Nonetheless, data are lacking regarding the management of EES during the pandemic. The object of this study was to understand current worldwide practices pertaining to EES for skull base/pituitary tumors during the SARS-CoV-2 pandemic and provide a basis for the formulation of guidelines.

METHODS

The authors conducted a web-based survey of skull base surgeons worldwide. Different practices by geographic region and COVID-19 prevalence were analyzed.

RESULTS

One hundred thirty-five unique responses were collected. Regarding the use of personal protective equipment (PPE), North America reported using more powered air-purifying respirators (PAPRs), and Asia and Europe reported using more standard precautions. North America and Europe resorted more to reverse transcriptase–polymerase chain reaction (RT-PCR) for screening asymptomatic patients. High-prevalence countries showed a higher use of PAPRs. The medium-prevalence group reported lower RT-PCR testing for symptomatic cases, and the high-prevalence group used it significantly more in asymptomatic cases.

Nineteen respondents reported transmission of COVID-19 to healthcare personnel during EES, with a higher rate of transmission among countries classified as having a medium prevalence of COVID-19. These specific respondents (medium prevalence) also reported a lower use of airborne PPE. In the cases of healthcare transmission, the patient was reportedly asymptomatic 32% of the time.

CONCLUSIONS

This survey gives an overview of EES practices during the SARS-CoV-2 pandemic. Intensified preoperative screening, even in asymptomatic patients, RT-PCR for all symptomatic cases, and an increased use of airborne PPE is associated with decreased reports of COVID-19 transmission during EES.

Published: December 2020

In this tumultuous time, the entire world has been shaken up by the COVID-19 outbreak. Italy has had one of the highest infection-related mortality rates. Bergamo, a city in eastern Lombardy, was among the most affected. Here, the authors describe the main healthcare actions taken at their institution to stem the crisis, with particular concern regarding the fate of their neurosurgery department. Among the different topics, the authors particularly focus on the retraining of neurosurgeons, organization of activities, and what should be the role of neurosurgeons during a pandemic.

Published: December 2020

OBJECTIVE

Telemedicine has rapidly expanded in the recent years as technologies have afforded healthcare practitioners the ability to diagnose and treat patients remotely. Due to the COVID-19 pandemic, nonessential clinical visits were greatly limited, and much of the outpatient neurosurgical practice at the authors’ institution was shifted quickly to telehealth. Although there are prior data suggesting that the use of telemedicine is satisfactory in other surgical fields, data in neurosurgery are limited. This study aimed to investigate both patient and provider satisfaction with telemedicine and its strengths and limitations in outpatient neurosurgery visits.

METHODS

This quality improvement study was designed to analyze provider and patient satisfaction with telemedicine consultations in an outpatient neurosurgery clinic setting at a tertiary care, large-volume, academic center. The authors designed an 11-question survey for neurosurgical providers and a 13-question survey for patients using both closed 5-point Likert scale responses and multiple choice responses. The questionnaires were administered to patients and providers during the period when the clinic restricted in-person visits. At the conclusion of the study, the overall data were analyzed qualitatively and quantitatively.

RESULTS

During the study period, 607 surveys were sent out to patients seen by telehealth at the authors’ academic center, and 122 responses were received. For the provider survey, 85 surveys were sent out to providers at the authors’ center and other academic centers, and 40 surveys were received. Ninety-two percent of patients agreed or strongly agreed that they were satisfied with that particular telehealth visit. Eighty-eight percent of patients agreed that their telehealth visit was more convenient for them than an in-person visit, but only 36% of patients stated they would like their future visits to be telehealth. Sixty-three percent of providers agreed that telehealth visits were more convenient for them than in-person visits, and 85% of responding providers stated that they wished to incorporate telehealth into their future practice.

CONCLUSIONS

Although the authors’ transition to telehealth was both rapid and unexpected, most providers and patients reported positive experiences with their telemedicine visits and found telemedicine to be an effective form of ambulatory neurosurgical care. Not all patients preferred telemedicine visits over in-person visits, but the high satisfaction with telemedicine by both providers and patients is promising to the future expansion of telehealth in ambulatory neurosurgery.

OBJECTIVE

Coronavirus disease 2019 (COVID-19) has changed the way in which cancer is treated. Patients with high-grade glioma (HGG) are believed to be in a vulnerable category. The aim of this study was to describe the experience of a hub cancer center and the measures that were put in place for treatment of patients with newly diagnosed and recurrent glioma.

METHODS

To prevent in-hospital contagion and preserve the safety of health professionals and patients, specific protocols and strict regulations were introduced. Physical distancing, use of surgical masks, and diligent hand hygiene were adopted. Each case was discussed in a multidisciplinary board meeting before treatment. All patient candidates for surgical procedures were tested for SARS-CoV-2 with a nasopharyngeal swab and a chest CT scan. Indications for surgery were the radiological suspicion of HGG in patients with a good performance status and/or the rapid and progressive occurrence of neurological deficits. Adjuvant treatments were performed only in cases of HGG. This therapy consisted of conventional fractional radiotherapy (RT; 60 Gy/30 fractions) with concomitant and adjuvant temozolomide chemotherapy (TMZCHT) in younger patients; in elderly patients, a short course of RT was employed (40.5 Gy/15 fractions). For recurrent HGG, treatments were assessed after a careful evaluation of the patient’s general condition, neurological status, and risk of early impairment in neurological status if not treated. During simulation CT for the RT plan, each patient underwent a chest CT study. In cases in which an imaging study was suspicious for COVID-19 pneumonia, the patient was immediately isolated and rapidly underwent nasopharyngeal swab testing.

RESULTS

Between March 1 and April 30, 2020, 23 HGGs were treated, and these cases are included in the present evaluation. Fifteen patients harboring newly diagnosed glioblastoma (GBM) underwent resection followed by a regimen of chemotherapy and RT, and 3 patients with newly diagnosed anaplastic oligodendroglioma underwent surgery followed by adjuvant RT. Five patients were treated for recurrent GBM, and they received surgery plus adjuvant RT. One patient in whom the simulation CT study was suspicious for COVID pneumonia was tested with a nasopharyngeal swab, which proved positive for SARS-CoV-2 infection. No patients contracted COVID-19 during hospitalization for surgery or during RT treatment. Corticosteroid therapy was administered to all patients beginning on the 1st day of RT.

CONCLUSIONS

The authors’ experience during the COVID-19 pandemic showed that patients with HGG can be treated in the most effective manner without a compromise in safety. Careful selection criteria and a multidisciplinary evaluation are pivotal to assessing the optimal therapeutic strategy.

Abstract: The people of Sendang Village, Jambon Subdistrict, Ponorogo Regency, especially Pondok Country, were mostly farmers. Some farmers in Pondok Country grew vegetables, especially eggplant. In general, eggplant was only intercropping plant or crop interlude in some part of the land they plant. So far, the farmers had suffered losses because the eggplants’ prices tended to be unstable. Therefore, this community service activity was carried out to empower the people of Pondok Country in social entrepreneurship activities to solve the problems that existed in the community environment. The community service team provided training to the community by making alternative processed products in the form of eggplant chips. This activity consisted of three stages, namely preparation, implementation and evaluation. At the implementation stage, the activities carried out in the form of training in making eggplant chips. The training was held in one of the houses of the residents. The result of this activity was the formation of social entrepreneurship growing in the community environment with products in the form of processed eggplant chips that can increase the community income. The processing of eggplants into chips could also minimize the farmers' losses because the chips were not stale easily and the prices became stable.

Background: Evidence suggests that psychosocial factors are associated with cognitive health in older adults; however, associations of psychosocial factors with cognition remain largely unexamined in middle-aged and older Hispanics/Latinos. Objective: To examine the cross-sectional associations of psychosocial factors with cognitive function among middle-aged and older Hispanics/Latinos living in the US. Methods: Baseline (2008–2011) data from the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (n = 2,818; ages 45–74) were used to examine the associations of each psychosocial factor with global cognition (GC), verbal learning, verbal memory, verbal fluency, and processing speed independent of age, sex, education, Hispanic/Latino background, income, language, and depressive symptoms. Psychosocial variables included: intrapersonal factors (ethnic identity, optimism, and purpose in life), interpersonal factors (family cohesion, familism, social network embeddedness, and social support), and social stressors (perceived ethnic discrimination, loneliness, and subjective social status). Results: In fully-adjusted models, purpose in life and social support were each positively associated with all five cognitive variables. Loneliness was negatively associated with GC, verbal learning, memory, and processing speed. Ethnic identity was positively and familism negatively associated with GC, verbal fluency, and processing speed. Family cohesion was positively associated with verbal learning. Conclusion: These findings extend previous evidence from older, largely non-Hispanic White cohorts to show that higher purpose in life and social support are also strongly associated with cognitive health among middle-aged and older Hispanics/Latinos. We also highlight that intrapersonal factors, interpersonal factors, and social stressors have differential relationships with individual cognitive tests.

Published: December 2020

Background: The semantic variant of primary progressive aphasia (svPPA) is characterized by a progressive loss of semantic knowledge impairing the ability to name and to recognize the meaning of words. Objective: We aimed to evaluate the immediate and short-term effect of errorless learning speech therapy on the naming and recognition of commonly used words in patients with svPPA. Methods: Eight participants diagnosed with svPPA received 16 sessions of intensive errorless learning speech therapy. Naming and word comprehension tasks were evaluated at baseline, immediately postintervention, and at follow-up after 1, 3, and 6 months. These evaluations were performed using two item sets (a trained list and an untrained list). Results: In the naming tasks, patients showed a significant improvement in trained items immediately after the intervention, but that improvement decayed progressively when therapy ended. No improvements were found either in trained comprehension or in untrained tasks. Conclusion: Errorless learning therapy could improve naming ability in patients with svPPA. This effect may be due to the relative preservation of episodic memory, but the benefit is not maintained over time, presumably because there is no consolidation.
Brachionus rotifers as a model for investigating dietary and metabolic regulators of aging
Authors: Gribble Kristin E.
Published: December 2020

Because every species has unique attributes relevant to understanding specific aspects of aging, using a diversity of study systems and a comparative biology approach for aging research has the potential to lead to novel discoveries applicable to human health. Monogonont rotifers, a standard model for studies of aquatic ecology, evolutionary biology, and ecotoxicology, have also been used to study lifespan and healthspan for nearly a century. However, because much of this work has been published in the ecology and evolutionary biology literature, it may not be known to the biomedical research community. In this review, we provide an overview of Brachionus rotifers as a model to investigate nutritional and metabolic regulators of aging, with a focus on recent studies of dietary and metabolic pathway manipulation. Rotifers are microscopic, aquatic invertebrates with many advantages as a system for studying aging, including a two-week lifespan, easy laboratory culture, direct development without a larval stage, sexual and asexual reproduction, easy delivery of pharmaceuticals in liquid culture, and transparency allowing imaging of cellular morphology and processes. Rotifers have greater gene homology with humans than do established invertebrate models for aging, and thus rotifers may be used to investigate novel genetic mechanisms relevant to human lifespan and healthspan. The research on caloric restriction; dietary, pharmaceutical, and genetic interventions; and transcriptomics of aging using rotifers provide insights into the metabolic regulators of lifespan and health and suggest future directions for aging research. Capitalizing on the unique biology of Brachionus rotifers, referencing the vast existing literature about the influence of diet and drugs on rotifer lifespan and health, continuing the development of genetic tools for rotifers, and growing the rotifer research community will lead to new discoveries a better understanding of the biology of aging.

Communication Scenarios of Misunderstanding
Authors: Kazarinova N. V.
Published: December 2020

Introduction. The proposed paper discusses communication situations of mutual misunderstanding up to mutual rejection of each other by the parties. The research assumption is that misunderstanding in human communication is not necessarily accompanied by its overcoming. “Miscommunication communication” forms a communicative space that reveals the diversity of practices of personal self-realization, intergroup and intercultural interaction, while retaining the perception of the other side as incomprehensible.

Methodology and sources. The methodological framework for analysis is a social constructionalist approach to the study of social reality, offering a conceptualization of the practical and observable actions of individuals or, in other words, “what people do when they act”. According to pragmatically oriented methodology, we cannot make an exhaustive conclusion about the internal reasons that motivate people to act in one way or another, but we can consider linguistic and non-linguistic actions that are perceived and interpreted by them as having a certain meaning and, therefore, trigger a certain response. The meanings that communicators give to a message are not pre-defined, but are created, produced, and constructed in a communicative interaction through contextspecific discursive procedures and practices, while also triggering specific socially recognizable types of contexts.

Results and discussion. The variant of classification of various types of cognitive and communicative experience acquired by people in situations of misunderstanding is offered. Empirical data are the records of interviews, conversations, and comments that are at our possession. The basis for distinguishing between communicative scenarios of misunderstanding is the values in the range of “expanding one's own experience” ↔ “isolation from others' experience”. The structure of description of the selected situations includes: communicative status of the participant; verbal formulas that determine the choice of vector by the participants of the communication; characteristics of cognitive and communicative experience generated by a situation of misunderstanding; examples and illustrations containing replicas, comments, description of life situations of collision with misunderstanding, corresponding to a specific communicative scenario.

Conclusion. Situations of misunderstanding are developed in scenarios that provide their participants with the resources to cope with the threat of risk to their personal or group (cultural) identity. The range of cognitive and communicative practices ranges from recognizing the value of cultural (social) diversity for social and personal development to discriminating against others, including violence and the exclusion of the incomprehensible from interaction. Discussion of the issue of “understanding misunderstanding” makes it possible to fit misunderstanding into the social fabric  of human behavior practices as a vital resource for any social community.
Optimization of Shovel-Truck Productivity in Quarries
Authors: J Matsimbe
Published: December 2020

In open pit operations, the loading equipment drives production but the haulage fleet drives costs. Most quarries in Malawi face challenges in shovel-truck productivity due to factors which require optimization of mine operations. The case of Njuli quarry is used to come up with a model that can be applied by quarries in Malawi. Loading and haulage costs account as much as 50 – 60 % of a company’s total operation cost hence it is necessary to maintain an efficient shovel-truck system. This research optimized the shovel-truck productivity per day, applied the queuing theory to the haul cycle, and suggested ways to improve the efficiency of materials handling operations. Examining a match between truck body size and shovel bucket size yielded the size of the load, cycle time and number of trips in an hour. The cycle time depended on the weight of the equipment, the horsepower of the engine, haul distance, and condition of the road plus dump area. Quarry companies in Malawi will apply this new knowledge to improve equipment selection and maximize the tonnage of aggregates produced per day to meet production targets.

Published: December 2020

Batam City is the economic center of Riau Province with a predicted population of 1.8 million people in 2025. To support economic development, Batam City needs a reliable supply of raw water. Mukakuning and Duriangkang reservoirs, which are cascade reservoirs, are the largest contributors to raw water supply in Batam City. This study aims to determine the maximum capacity of the two reservoirs to meet current and future raw water demand. Discharge in the watershed is calculated using daily HEC-HMS model calibrated using Duriangkang Reservoir water level data. The storage of Mukakuning and Duriangkang Reservoir are 6.3 and 106.1 million m3 respectively, equivalent to 39% and 77% of the runoff volume of each watershed, classifying the two reservoirs in the multi-year category. Using current operation, the two reservoirs can supply up to 3.24 m3/s at 100% reliability, compared to existing capacity of 3.1 m3/s. The water loss is dominated by evaporation which reaches 32.6 million m3/year while spilled water is only 8.3 million m3/year. At 95% reliability, the reservoirs are almost at maximum capacity and able to supply 4.03 m3/s of raw water with the spilled water is only 0.4 million m3/year. Efforts to increase capacity by increasing normal water levels are not effective and lead to dam overtopping in PMF condition. More effective way to increase water supply can be obtained by changing operating patterns. If the reservoir is in dry condition, determined by predicted SPI, the water supply is limited so that the discharge can be utilized for a longer period.
Laura Marchig e Carla Rotta. Considerazioni introduttive per un confronto tra due innovatrici della letteratura istro-quarnerina
Authors: Bortoletto Anna , Deghenghi Olujić Elis
Published: December 2020

Questo lavoro desidera offrire una panoramica, comparativa, sulla produzione di due autrici appartenenti alla fase più recente della letteratura istro-quarnerina: Laura Marchig e Carla Rotta. Infatti, nonostante le due si dedichino a generi letterari differenti – rispettivamente poesia e prosa – le loro produzioni presentano dei punti di contatto particolarmente interessanti. Non solo, infatti, costituiscono un punto di rottura notevole con la tradizione letteraria istro-quarnerina precedente; ma entrambe, al netto delle evidenti differenze stilistiche, offrono una visione squisitamente femminile dei grandi temi della vita umana che, in più di un’occasione, tende a convergere. Il lavoro, dunque, dopo aver presentato brevemente le due autrici e averle collocate all’interno della letteratura istro-quarnerina, procederà con l’analisi di alcuni temi peculiari in due opere emblematiche: la silloge poetica T(t)erra per Marchig e la raccolta di racconti Femminile Singolare per Rotta.
Il nazionalismo della letteratura britannica prima della Grande Guerra e l’esperienza dei War Poets
Authors: Giunta Angelo
Published: December 2020

L’immagine di un Regno Unito visto come Eden inconsapevole della tragedia che sta per lacerarlo è diffusa, ma piuttosto falsa. L’apparente serenità nasconde una violenza latente e gravi questioni interne e la guerra, quindi, non fa altro che accelerare un processo già in atto.
Di tutta la letteratura inglese del Ventesimo secolo, la poesia di guerra sembra, sotto molti punti di vista, una “parentesi” all’interno del panorama letterario. La war poetry è il prodotto di un determinato periodo storico, sociale e culturale venutosi a formare nella Prima guerra mondiale. Tra i migliori poeti della Grande Guerra troviamo Rupert Brooke, Wilfred Owen e Siegfried Sassoon. Il fatto che molti poeti siano ufficiali – ma non alti ufficiali – permette loro di essere in contatto, a livello socio-culturale, con i ranghi elevati dell’esercito e, fisicamente, con i soldati semplici. In questo modo hanno una visione più ampia della realtà in trincea.
Aspetti socioculturali nella prassi glottodidattica

Published: December 2020

L’insegnamento della lingua italiana non può essere separato mai del tutto dagli aspetti culturali della nostra storia e civiltà, in quanto esiste tra i due una profonda e intima interconnessione. Diversi esiti linguistici e altrettanti enunciati o idiomatismi si spiegano proprio con l’ausilio di ragioni storiche, sociali e antropologiche, in una parola “culturali”, proprie del Paese. Una delle possibili chiavi di volta per trasmettere ai discenti stranieri elementi della nostra civiltà è quella di partire dalle loro osservazioni critiche e coinvolgerli in qualità di giudici dei nostri stili di vita, delle nostre abitudini e della nostra mentalità per porli al centro del processo di apprendimento in una veste più attiva, partecipe e interlocutoria.

Tanatología: Enfoque histórico-filosófico a la muerte en el contexto de la medicina legal y el derecho
Authors: Figueiredo Antonio Macena de
Published: December 2020

La Tanatología Forense integra una de las ramas de la Medicina Legal relacionada con aspectos científicos con la muerte, sus signos y su naturaleza. Aunque la muerte es un fenómeno natural tiene implicaciones en el ámbito jurídico y social, pero siempre ha sido un enigma en la cultura occidental. El objetivo es discutir el tema tanatológico bajo tres puntos de reflexión: cortar desde la perspectiva de los filósofos de la Antiguedad que más trabajaron en este tema, la visión de la muerte en Occidente narrada por el historiador francés Philippe Ariés y cómo Medicina Legal y Derecho ha trabajado este tema en la práctica profesional. Este es un estudio de revisión de la literatura especializada. Siendo demostrado como Medicina-Legal y Derecho La Tanatología contribuyen a estas reflexiones, así como en la definición y concepto de muerte, sin embargo, fueron los filósofos de Platón (428-347 a. C.) e historiadores que este tema se ha abordado en varios aspectos. Se concluye que la forma de abordar este tema se ha transformado con el tiempo. Hoy en día, el fenómeno de la muerte está medicalizado, hospitalizado, alejado de la familia, la sociedad e incluso la formación académica. Aunque la Medicina Legal y el Derecho son disciplinas intrínsecamente asociadas, el tema todavía está lejos de la enseñanza y la práctica profesional. Evidencia que demuestra la necesidad de rediscusar el tema en la formación de profesionales médicos y de derecho.

Towards Discovering Employee-Worker Interactions - Aspects of Conclusion of Psychological Contract
Authors: Rogozińska-Pawełczyk Anna
Published: December 2020

The psychological contract refers to presumed and subjective beliefs in relation to the exchange relationship, considered mainly between employees and employers. An immanent part of the psychological contract is its subjectivity and the relationship of exchange of expectations, promises or commitments of both parties to the employment relationship. The conditions in which modern organisations have to operate justify the use of the psychological contract for the analysis of employment relationships, but do not yet take into account the emerging new form of relationship at the workplace. Currently, thanks to the development of new technologies, including artificial intelligence, the role of robots in the workplace is growing. The aim of the article is to outline the framework for building the involvement of employees in technologically, socially and emotionally advanced forms of artificial intelligence. The manifestations of workers' interactions with social robots within the framework of a contractual partnership will be defined. To this end, the arguments for the possibility of concluding a psychological contract between a human and a robot based on the theory of exchange and the standard of reciprocity, which can set new directions for research in this area, are reviewed.

Published: December 2020

Low dietary diversity in the rural household is a major problem in developing countries due to different factors. The aim of this study is to assess dietary diversity level and its associated factors among indigenous and nonindigenous households in Bambasi district, Western Ethiopia. A cross sectional data which covered a sample of 260 households collected using a semi structured interview schedule. A multi stage sampling procedure was used. A household dietary diversity score based on 12 food groups was created using seven days recalls. A descriptive statistics analysis was applied. An order logistic regression model was used to determine the factors that influence both indigenous and nonindigenous household dietary diversity. The result of the study revealed that indigenous household had better dietary diversity status than nonindigenous household heads. Age of the household heads, access to extension and access to nearest markets are the major determinants of rural households in the area. Despite of this, access to credit, farm income, farm size and dependency ratio are the major determinants for nonindigenous household heads whereas participation in small scale irrigation and education are major factors of dietary diversity of the indigenous household heads. Therefore, we recommended that food and nutrition interventions focusing on improving dietary diversity and quality should due attention to develop community specific interventions instead of generalized interventions. However, further investigation focused on seasonal dietary diversity and individual level dietary diversity of the study area
Calcium Nutrition in Coffee and Its Influence on Growth, Stress Tolerance, Cations Uptake, and Productivity

Published: December 2020

Calcium (Ca2+) is an important macronutrient in coffee and is involved in several physiological processes that influence crop growth, development, productivity, and stress response. This paper presents results from five experiments conducted on coffee under greenhouse and field conditions for over 5 years (2014–2018). The main objective of this study was to evaluate the influence of Ca+2 application on coffee growth, development, abiotic stress response, cation uptake, leaf cell structure, and productivity. The results show that Ca+2 directly influences the growth and development of plants and has a strong effect on root growth. Drought stress and low Ca+2 rates of 8 mg.L−1 showed no differences in photosynthetic rates (PN) and biomass accumulation; high Ca+2 rates between 75 and 150 mg.L−1 increased PN and biomass accumulation in plants under drought stress, with a positive correlation between Ca+2 content in the leaves and PN with and without drought stress. High air temperature (>30°C) reduced PN rates, and the treatment with proper Ca+2 application showed better PN compared to the treatments with low Ca+2. Ca+2 application showed a synergistic effect with potassium (K+) uptake and no influence on the magnesium (Mg+2) uptake but a reduction in the leaf concentration with the increase in Ca+2 application. Additionally, coffee plants with proper Ca+2 application showed thicker leaves, denser epidermis, and larger, more compact, and better-structured palisade parenchyma compared with the plants treated with Ca+2 at lower rates. After 5 years, the mean coffee yield showed a polynomial response with respect to the doses of Ca+2 applied, with optimum rate of 120 kg CaO ha−1year−1 and a peak of Ca+2 uptake by the coffee cherries during 110–220 days after flowering.
A Novel Fluorescent Test Papers Based on Carbon Dots for Selective and Sensitive Detection of Cr (VI)

Published: December 2020

In recent years, carbon dots (CDs) are promising fluorescence probes for ions detection. In this paper, the CDs which are with an average diameter of 5.5 nm were synthesized through a simple one-step hydrothermal carbonization of ethylene diamine tetraacetic acid (EDTA) salt. The CDs have strong yellow photoluminescence (PL) with a maximum emission intensity at 550 nm under an excitation wavelength of 450 nm. As the electron transfer will occur between Cr (VI) and the CDs, yellow fluorescence was quenched after adding the Cr (VI) ions. The CDs probe allows the detection of Cr (VI) ions over a concentration range from 0 to 0.1 M (R2 = 0.987) and the lower detection limit is 10−5 M. Simultaneously, the CDs show highly selectivity and stability toward the detection of Cr (VI) ions.

Published: December 2020

As we rapidly approach a post-antibiotic era in which multi-drug resistant bacteria are ever-pervasive, antimicrobial peptides (AMPs) represent a promising class of compounds to help address this global issue. AMPs are best-known for their membrane-disruptive mode of action leading to bacteria cell lysis and death. However, many AMPs are also known to be non-lytic and have intracellular modes of action. Proline-rich AMPs (PrAMPs) are one such class, that are generally membrane permeable and inhibit protein synthesis leading to a bactericidal outcome. PrAMPs are highly effective against Gram-negative bacteria and yet show very low toxicity against eukaryotic cells. Here, we review both the PrAMP family and the past and current definitions for this class of peptides. Computational analysis of known AMPs within the DRAMP database (http://dramp.cpu-bioinfor.org/) and assessment of their PrAMP-like properties have led us to develop a revised definition of the PrAMP class. As a result, we subsequently identified a number of unknown and unclassified peptides containing motifs of striking similarity to known PrAMP-based DnaK inhibitors and propose a series of new sequences for experimental evaluation and subsequent addition to the PrAMP family.

Purpose

Acromegaly is a rare, intractable endocrine disease. We aimed to describe the patient characteristics, diagnostic delays, treatment patterns, treatment outcomes, comorbidities and treatment costs of acromegaly in China.

Methods

This is a nationwide cross-sectional study. Patients diagnosed with and treated for acromegaly between 1996 and 2019 across China were surveyed via the Chinese Association of Patients with Acromegaly platform.

Results

In total, 473 patients (58.8% females, mean age at diagnosis: 39.4±9.5 years) were included. The median disease duration was 3 years. The most common symptoms were extremity enlargement (91.8%) and facial changes (90.1%). Overall, 63.0% of patients experienced diagnostic delays within healthcare systems; 63.8% of the delays were <1 year. The most common first-line therapy was surgery with a transsphenoidal (76.1%) or transcranial approach (3.2%). Somatostatin analogues or dopamine agonists were administered in 20.5% of the patients as first-line therapies and in 41.7% as adjuvant therapies. Radiotherapy was performed in 32.1% of patients, 99.3% of whom received radiotherapy as an adjuvant therapy. After a median 5-year follow-up, 46.2% achieved biochemical control. Comorbidities were reported in 88.2% of the patients at follow-up; memory deterioration and thyroid nodules were the most common. Controlled patients had greater improvements in symptoms and comorbidities during follow-up than uncontrolled patients. The annual per-capita cost-of-treatment was $11013 in 2018, with medical treatments being the largest contributor (67%). Medical insurance covered 47.2% of all treatment costs.

Conclusion

This study provides the first comprehensive description of real-world acromegaly data in China, serving as a basis for future population-based studies.
