Published: September 2020

Introduction:

Indocyanine green (ICG) angiography is a novel technology that has been predictive of postoperative wound complications. It is unknown whether this technology can successfully predict complications after sarcoma resection. In this study, we aimed to evaluate the sensitivity and specificity of ICG angiography in predicting postoperative wound complications after soft-tissue sarcoma resection.

Methods:

A prospective cohort study of 23 patients was performed beginning October 2017 at our institution. Patients who underwent soft-tissue sarcoma resection were included. After tumor resection and wound closure, evaluation of tissue perfusion in skin edges was performed with ICG angiography. Wound complications were recorded in the postoperative follow-up.

Results:

Eight patients developed postoperative wound complications. Six patients were predicted to have wound complications on the final ICG scans. The accuracy of ICG angiography was dependent on the anatomic location, with improved accuracy in the lower extremity. ICG angiography had a sensitivity of 50%, a specificity and a positive predictive value of 100%, and a negative predictive value of 70% for wound complications after soft-tissue sarcoma resections located in the lower extremity.

Conclusion:

ICG angiography has a high predictive value in the lower extremity for postoperative wound complications.

At the Canadian Testis Cancer Workshop, the multidisciplinary management of testis cancer care was discussed. The two-day workshop involved urologists, medical and radiation oncologists, pathologists, radiologists, physician’s assistants, residents, fellows, nurses, patients, and patient advocacy group members.

This review summarizes the discussion regarding clinical dilemmas in local and regional testis cancer. We present cases that highlight the need for a coordinated approach to individualize care. Overarching themes include the importance of a multidisciplinary approach to testis cancer, willingness to involve a high-volume experienced center, and given that the oncological outcomes are excellent, a reminder that clinical decisions need to prioritize selecting a strategy with the least treatment-related morbidity when safe to do so.
Computed Tomography/Magnetic Resonance Imaging (CT/MRI) Image Registration and Fusion Assessment for Accurate Glioblastoma Radiotherapy Treatment Planning
Authors: Touabti Khalil Mohamed Mokhtar , Kharfi Faycal , Benkahila Karim , Merouane Sid-Ali
Published: September 2020

Background: In this study, computed tomography/magnetic resonance imaging (CT/MRI) image registration and fusion in the 3D conformal radiotherapy treatment planning of Glioblastoma brain tumor was investigated. Good CT/MRI image registration and fusion made a great impact on dose calculation and treatment planning accuracy. Indeed, the uncertainly associated with the registration and fusion methods must be well verified and communicated. Unfortunately, there is no standard procedure or mathematical formalism to perform this verification due to noise, distortion, and complicated anatomical situations. Objectives: This study aimed at assessing the effective contribution of MRI in Glioma radiotherapy treatment by improving the localization of target volumes and organs at risk (OARs). It is also a question to provide clinicians with some suitable metrics to evaluate the CT/MRI image registration and fusion results. Methods: Quantitative image registration and fusion evaluation were used in this study to compare Eclipse TPS tools and Elastix CT/MRI image registration fusion. Thus, Dice score coefficient (DSC), Jaccard similarity coefficient (JSC), and Hausdorff distance (HD) were found to be suitable metrics for the evaluation and comparison of the image registration and fusion methods of Eclipse TPS and Elastix. Results: The programmed tumor’s volumes (PTV) delineated on CT slices were approximately 1.38 times smaller than those delineated on CT/MRI fused images. Large differences were observed for the edema and the brainstem. It was also found that MRI considerably optimized the dose to be delivered to the optic nerve and brainstem. Conclusions: Image registration and fusion is a fundamental step for suitable and efficient Glioma treatment planning in 3D conformal radiotherapy that ensure accurate dose delivery and unnecessary OAR irradiation. MRI can provide accurate localization of targeted volumes leading to better irradiation control of Glioma tumor.

Espacialidade travesti: habitat de gênero e práticas topográficas de corpos trans nas artes da cena brasileira
Authors: Tavares Borges Leal Dodi
Published: September 2020

O artigo trata de interrogar os processos poético-topográficos nas artes cênicas a partir dos paradigmas espaciais instaurados pelas corporalidades transgêneras na cena brasileira recente. A reflexão põe em tensão os fenômenos de performatividade do espaço (Mostaço, 2016) e de performatividade transgênera (Leal, 2018b) buscando entender traços de habitat de gênero nas artes contemporâneas. A espacialidade travesti é então pensada a partir de configurações cênicas provocativas suscitadas por modos atitudinais de proteção e criação de gênero no ambiente. Neste sentido, a partir de incitações de processos criativos recentes, e da noção de racismo ambiental (Santos et al., 2016), analisamos as categorias da passabilidade, da reclusão e do cisplay como possíveis modos de violência ambiental às transgeneridades.

Published: September 2020

La rumiación ira es pensamiento perseverativo sobre un evento personalmente significativo ocurrido a la persona o las demás que conlleva a la ira y se constituye como factor de riesgo para la agresión. El objetivo fue realizar un análisis factorial confirmatorio e invarianza por sexo y edades de la Anger Rumination Scale [ARS]. Se conformó una muestra no probabilística de 640 personas con entre 18 y 63 años (M = 31.07, SD = 11.27), agrupadas por sexos (252 hombres, 378 mujeres) y edades (278 menores de 25 años, 352 mayores de 25 años). Los instrumentos fueron el ARS y el cuestionario de agresión reactiva y proactiva RPQ. Se encontró que el ARS presenta un ajuste favorable en un modelo de cuatro factores correlacionados con covarianzas residuales. A su vez, resultó invariante entre sexos y edades luego de imponer restricciones progresivas en el modelo confirmado, y presentó correlaciones significativas con la agresión reactiva y proactiva como evidencias de la validez de criterio predictivo. Se concluyó que el ARS presenta indicadores adecuados de fiabilidad y validez para ser usado en el contexto colombiano.

Anger rumination is perseverative thinking about a personally significant event that occurred to the person or others that leads to anger and constitutes a risk factor for aggression. The aim was to perform a confirmatory factor analysis and invariance by sex and age of the Anger Rumination Scale [ARS]. A non-probabilistic sample of 640 people between 18 and 63 years old (M = 31.07, SD = 11.27), grouped by sex (252 men, 378 women) and ages (278 under 25 years old, 352 over 25 years old) was formed. The instruments were the ARS and the RPQ reactive and proactive aggression questionnaire. It was found that the ARS presents a favorable fit in a four-factor model correlated with residual covariances. In turn, it was invariant between sexes and ages after imposing progressive restrictions on the confirmed model and presented significant correlations with reactive and proactive aggression as evidence of the validity of predictive criteria. It was concluded that the ARS presents adequate indicators of reliability and validity to be used in the Colombian context.

Authors: Meléndez-Domínguez Montserrat , Bermúdez María Paz
Published: September 2020

Existe una gran heterogeneidad regional y desconocimiento de la situación actual de la violencia de género (VdG) en los diferentes países de la Unión Europea (UE-28). El objetivo del presente trabajo es determinar la prevalencia actual de la VdG y de feminicidios en la UE-28 y en particular en España. Consiste en un estudio descriptivo observacional (análisis de documentos) seleccionando y analizando datos de las diferentes modalidades de la VdG y de feminicidios en los 28 países de la UE. Letonia, Dinamarca, Reino Unido, Suecia, Bélgica, Finlandia, Eslovaquia y Luxemburgo tienen tasas más altas que la media de la UE en todos los tipos de VdG y Finlandia, Hungría, Irlanda del Norte y Letonia poseen índices de prevalencia más altos en feminicidios. Con respecto a España, el 0,13% de las mujeres fueron víctimas de VdG y se producen 2,3 feminicidios por cada 1.000.000 mujeres, situándose España entre los países con tasas más bajas. Se concluye que el maltrato psicológico es el más prevalente en la UE-28, sin embargo, existe una dificultad para la comparación de datos de los diferentes países debido a la inexistencia de una conceptualización legal común de la VdG.

There is a great regional heterogeneity and ignorance of the current gender-based violence (GBV) situation in the different countries of the European Union (EU-28). The aim of this paper is to determine the current prevalence of GBV and femicides in the EU-28 and in Spain in particular. This study consists of an observational descriptive study (document analysis) which selects and analyses data belonging to the different modalities of GBV and femicides in the EU-28 countries. Latvia, Denmark, United Kingdom, Sweden, Belgium, Finland, Slovakia and Luxembourg possess higher rates than the EU average in all types of GBV while Finland, Hungary, Northern Ireland and Latvia possess higher prevalence rates in femicide. With respect to Spain, 0.13% of women were victims of GBV and 2.3 femicides occur for every 1.000.000 women, with Spain being among the countries with the lowest rates. It is therefore concluded that psychological abuse is the most prevalent within the EU-28, however, it is difficult to compare said data from different countries due to the lack of a common legal conceptuaisation of GBV.
Symposium Review

The Arts of James Baldwin and Beauford Delaney,” held at the University
of Tennessee on 19–21 February 2020.
The Warrior and the Poet
Authors: Binford Nicholas
Published: September 2020

Artists, scholars, and popular media often describe James Baldwin as
revolutionary, either for his written work or for his role in the civil rights
movement. But what does it mean to be revolutionary? This article contends that
thoughtlessly calling James Baldwin revolutionary obscures and erases the
non-revolutionary strategies and approaches he employed in his contributions to
the civil rights movement and to race relations as a whole. Frequent use of
revolutionary as a synonym for “great” or
“important” creates an association suggesting that all good things
must be revolutionary, and that anything not revolutionary is insufficient,
effectively erasing an entire spectrum of social and political engagement from
view. Baldwin’s increasing relevance to our contemporary moment suggests
that his non-revolutionary tactics are just as important as the revolutionary
approaches employed by civil rights leaders such as Malcolm X or Martin Luther
King, Jr.
Baptism by History
Authors: Wilbourn Miller
Published: September 2020

This essay reads James Baldwin’s first novel, Go Tell It on the
Mountain, through the lenses of European existentialism and Black
existential thought to arrive at a new understanding of the novel itself as well
as essential stages of its development. Archival sources and close reading
reveal Baldwin’s historically and existentially informed artistic vision,
summed up in the terms hindsight and insight.
His thoughtful, uncomfortable engagement with the past leads to a recuperated
relationship to the community and constitutes existential hindsight, which
informs his inward understanding of himself—his insight. This
investigation draws on various works from Baldwin’s fiction, essays,
interviews, and correspondence to arrive at a better understanding of the
writer’s intellectual and artistic development, focusing especially on
the professed objectives behind, and major revisions of, the novel. I conclude
the essay through a close reading of the conversion scene that constitutes Part
Three of Go Tell It on the Mountain.
Alstrom syndrome gene is a stem-cell-specific regulator of centriole duplication in the Drosophila testis
Authors: Chen Cuie , Yamashita Yukiko M
Published: September 2020

Asymmetrically dividing stem cells often show asymmetric behavior of the mother versus daughter centrosomes, whereby the self-renewing stem cell selectively inherits the mother or daughter centrosome. Although the asymmetric centrosome behavior is widely conserved, its biological significance remains largely unclear. Here, we show that Alms1a, aDrosophilahomolog of the human ciliopathy gene Alstrom syndrome, is enriched on the mother centrosome inDrosophilamale germline stem cells (GSCs). Depletion ofalms1ain GSCs, but not in differentiating germ cells, results in rapid loss of centrosomes due to a failure in daughter centriole duplication, suggesting that Alms1a has a stem-cell-specific function in centrosome duplication. Alms1a interacts with Sak/Plk4, a critical regulator of centriole duplication, more strongly at the GSC mother centrosome, further supporting Alms1a’s unique role in GSCs. Our results begin to reveal the unique regulation of stem cell centrosomes that may contribute to asymmetric stem cell divisions.
Ribosome recycling is not critical for translational coupling in Escherichia coli
Authors: Saito Kazuki , Green Rachel , Buskirk Allen R
Published: September 2020

We used ribosome profiling to characterize the biological role of ribosome recycling factor (RRF) inEscherichia coli. As expected, RRF depletion leads to enrichment of post-termination 70S complexes in 3′-UTRs. We also observe that elongating ribosomes are unable to complete translation because they are blocked by non-recycled ribosomes at stop codons. Previous studies have suggested a role for recycling in translational coupling within operons; if a ribosome remains bound to an mRNA after termination, it may re-initiate downstream. We found, however, that RRF depletion did not significantly affect coupling efficiency in reporter assays or in ribosome density genome-wide. These findings argue that re-initiation is not a major mechanism of translational coupling inE. coli. Finally, RRF depletion has dramatic effects on the activity of ribosome rescue factors tmRNA and ArfA. Our results provide a global view of the effects of the loss of ribosome recycling on protein synthesis inE. coli.
Hidden Constructs of Sexual Victimization of Men and Boys in Armed Conflict: Prosecutorial and Jurisdictional Trajectories of the International Criminal Courts and Tribunals
Authors: Frunse Tamara
Published: September 2020

During armed conflict, sexual violence against women regularly takes on different forms than against the male gender. Frequently, men and boys are attacked either by coercion to witness sexual violence committed against their family and community members, or to rape and sexually assault
others. The shared feature of both forms of such victimization is that they rarely constitute an attack on the individual alone. Instead, they are utilized by perpetrators as a war tactic to debase entire communities. Protection for male victims of these forms of sexual violence is limited
due to a disconnect between formal statutory provisions under International Criminal Law (ICL) criminalizing sexual violence and the jurisprudential interpretation thereof. The jurisprudence of the international criminal courts and tribunals has been widely criticized in academic literature
for misclassifying sexual harm against men and accommodating it incoherently under various provisions other than the explicit sexual violence norms. The prosecutorial and jurisprudential dichotomy partly originates in the lack of clarity surrounding these selected forms of sexual violence.
In light of their devastating impact on men and boys, this article aims to map the inconsistencies within and between selected international criminal courts and tribunals and prompts to rethink current international criminal jurisprudence to coherently address and condemn such forms of sexual
violence.

Published: September 2020

The breeding activity of Himalayan sucker frog (Amolops himalayanus), was studied under natural conditions at Bodidrang stream, Kanglung, Trashigang, Bhutan, for 12 months. We examined the correlation between meteorological factors (relative humidity, temperature and rainfall) and sightings of adult, juvenile, and tadpole/larvae individuals as well as egg masses from monthly surveys using Pearson Correlation in statistical software (Python 3.6). A. himalayanus was an explosive breeder influenced by the high seasonality in Bhutan. Adult, juvenile, and larvae individuals recorded had a positive Pearson correlation with monthly mean rainfall. There was a strong correlation between rainfall and adult sightings (r=0.732), however tadpoles sightings had a low correlation (r=0.178). We observed moderate positive correlations of temperature and relative humidity with adult (r=0.536; r=0.442) and juvenile (r=0.398; r=0.252) individuals, while tadpoles had low positive correlation for relative humidity (r =0.048) respectively. Brief note of amplexus position of A. himalayanus is discussed.

The extract was subjected to phytochemical screening, DPPH inhibition, ferric reducing antioxidant power (FRAP), nitric oxide determination, antioxidant vitamins and minerals composition analysis. All analyses were carried out using standard biochemical methods. The phytochemical evaluation of the plant extract showed the presence of flavonoids (24.20 ± 0.14 mg QE/g), Alkaloids (15.87 ± 1.71 mg/g), total phenol (12.73 ± 0.61 mg GAE/g), tannins (9.24 ± 0.03 mg TAE/g), terpenoids (8.90 ± 0.96 mg/g), steroids (2.65 ± 0.55 mg/g) and saponins (5.55 ± 0.76 mg/g). The in vitro antioxidant determination showed that the extract had antioxidant properties in a concentration dependent manner. The antioxidant property of the sample was compared to that of ascorbic acid (for DPPH and nitric oxide determination) and gallic acid (for FRAP) as standards. The antioxidant mineral composition of the extract revealed the presence of zinc (1.82 ± 0.03 mg/100g) and selenium (0.59 ± 0.04 mg/100g). The antioxidant vitamins composition of the extract showed moderate concentrations of vitamin C (0.35 ± 0.01 mg/100 g) and vitamin E (0.68 ± 0.07 mg/100g). The result of this study revealed that methanol extract of Duranta erecta leaves could be a good source of antioxidants.

Maize is one of the most important cereal crops of Kashmir Valley where it serves as a source of food, feed, fodder and industrial raw material, providing enormous opportunity for crop diversification, value addition and employment generation. However, the average productivity of maize in Kashmir Valley is quite low (1.5 t ha-1) when compared to the national productivity (2.5 t ha-1). The development, dissemination and adoption of high yielding, early maturity, cold tolerant maize hybrids can serve as the most economical, effective and coherent approach to contribute significantly towards increasing maize production in Kashmir Valley. A single cross hybrid SMH4 (Shalimar Maize Hybrid 4) has been developed to enhance the maize productivity in high altitude agro-ecologies of the Valley. SMH4 possesses very high yield potential of about 7.0-8.2 t ha-1 compared to 2.5-4.0 t ha-1 as realised by the predominantly grown landraces in hilly agro-ecosystems. The hybrid revealed the grain yield superiority of about 23.61% and the stover yield superiority of about 15.77% over the commercial check viz., Shalimar maize Hybrid 1. The variety is resistant to Turcicum leaf blight and common rust, besides showing resistance to stem borers and cut worms. SMH4 has a very good acceptability by farmers for its high yield potential (both grain and fodder), better seedling vigour and early maturity. SMH4 with the traits like cold tolerance and early maturity can play a potential role in enhancing the economy of maize growers under high altitude ecologies of Kashmir Valley. The development, upscaling and mass adoption of SMH4 in temperate agro-ecologies will lead to socio-economic upliftment of small and marginal farmers through increase in production, productivity and farm profitability.

Aims: This study was aimed at exploring tissue culture technique as a tool for mass propagation of some Cameroonian cocoyam (Xanthosoma sagittifolium) cultivars/landraces (red, yellow and white skin colour).

Study Design: The experiment was laid out in a completely randomized design with three treatments in four replications.

Place and Duration of Study: The study was conducted in the tissue culture laboratory of the Institute of Agricultural Research for Development, Bambui, Cameroon, in the first half of                  2018.

Methodology: Explants were gotten from three Cameroonian cocoyam landraces (red, white and yellow skin colour). Shoot tips were excised and cultured on Murashige and Skoog (MS)                  medium supplemented with 30 g of sucrose, 5ml of ascorbic acid, 4ml of 6- benzylaminopurine (BAP 1mg/l), 1 ml indole-3- acetic acid (IAA 1 mg/l) and 6 g of agar at pH of 5.8±0.1 for shoot initiation and proliferation. Data was collected after 4 weeks (number dead, number rooted, number of roots, number of buds) and 12 weeks (number of leaves, shoot length, number contaminated) of initiation.

Results: All the landraces responded positively to the growth media since none died. The number of explant rooted did not vary significantly (p > .05). The highest number of roots and buds were from the white cultivar, followed by the red cultivar. Analysis of variance revealed significant differences (p = .05) in most of the parameters measured except for number rooted. Highest numbers of leaves and shoot length were recorded from the red cultivar, followed by the yellow and white cultivars. However, the white cultivar (4.2) was more susceptible to pathogen than the yellow (3.5) and red (2.67) cultivar (F = 19.13, df = 2, 8, p < .001.

Conclusion: Cameroonian cocoyam cultivars responded positively as far as growth parameters are concern on growth media. It is recommended that the three cocoyam cultivars be followed from growth media to the field and evaluate their growth and yield parameters.

Poor aqueous solubility is the principle obstacle in accomplishing suitable oral bioavailability for huge proportion of drug composites in drug development todays. Nano-suspension is an emerging field of research in the scientific community to provide a new solution for poorly water-soluble active constituents. The objective of the nano-suspension is to reduce the drug particle size (100-200 nm) range, which enhance solubility and bioavailability of biopharmaceutical active compounds. Crude extract of Piper nigrum shows various biological activities but poor aqueous solubility so, there is a need to isolate the piperine from Piper nigrum and prepare its nano-suspension to reduce particle size and enhance its bioavailability. This review defines the principles behind nanosizing, the synthesis and characterization of piperine nano-suspension as well as the recent practice withapplication of such formulations in-vivo can be used as a better alternative to treat cardiovascular diseases with improved therapeutic efficacy compared to extract.

Objectives

Nail workers are exposed to many hazardous chemicals. Despite many warnings about health problems among nail workers in other countries, data concerning exposure to chemical hazards among nail workers is still limited in Vietnam. In this study, we aimed to identify exposure to volatile organic compounds and their relationship with occupational symptoms among Vietnamese female nail salon workers.

Methods

A cross-sectional study was conducted in Danang, Vietnam, from January 2019 to September 2019. Total 42 personal passive samplers were collected to evaluate 12 substances from 21 nail workers (15 salons) twice a week. We chose one representative worker from each of the nine salons with less than six workers and two representative workers from each of the six salons with over five workers for personal sampling based on the principle of similar exposure groups. We interviewed a total of 100 nail workers in 15 salons and 100 office workers in offices adjacent to the salons to compare occupational symptoms among them.

Results

The commonly detected compounds in nail salons were acetone (97.6%), butyl acetate (83.3%), and ethyl acetate and ethyl methacrylate (78%). The concentration of total target VOCs was related to the number of serviced customers, the concentration of CO2, and general ventilation used. The subjective symptoms were significantly higher for the nail workers than for the comparison subjects, that is, headache, nausea, nose irritation, skin irritation, shortness of breath, and confusion. Among 100 nail workers, nose irritation was significantly higher for nail workers who were exposed to acetone at levels exceeding the Vietnam occupational exposure limit (VOEL) adjusted with the Brief-Scala model.

Conclusions

Exposure to VOCs such as acetone in nail salons results in occupational symptoms among workers.

Published: September 2020

Background

Nurses are one of the population groups with the highest prevalence of musculoskeletal disorders (MSDs). At many sites, musculoskeletal symptoms (MS) represent a major health-care burden, adversely affecting nurses’ quality of life and giving rise to mental health issues.

Objectives

This study measured the prevalence of multi-body-site (two or more anatomical sites) musculoskeletal symptoms (MMS), and the association between MMS, a number of demographic and work characteristics, psychological distress, and the quality of life among district hospital nurses.

Material and Methods

A cross-sectional study was performed with 1179 nurses in Haiphong City using three questionnaires: the Modified Nordic; Quality of Life Enjoyment and Satisfaction Short Form (Q-LES-Q-SF); and the Kessler Psychological Distress Questionnaire (K6).

Results

Women have a higher MMS prevalence than men (57.1% in women vs 37.6% in men, P < .001). Having a higher number of anatomical sites of MS appears to be associated with a worse quality of life among nurses. Linear regression analysis found a number of other factors negatively associated with the nurses’ quality of life: gender (female), age (50-60 years old vs 19-29 years old), and psychological distress.

Conclusions

This study shows a high prevalence of MMS and the relationship between, on the one hand, MMS, gender, age, as well as psychological distress and, on the other hand, the quality of life among nurses in Vietnam. Further in-depth studies are needed to investigate the causal relationships between these indicators.

Objectives

To estimate hypertension prevalence and associated factors among female correctional officers (FCO) in female Brazilian prisons.

Methods

Cross-sectional, analytical study conducted in 15 female prisons in all five Brazilian regions between January 2014 and December 2015. The study population consisted of correctional officers with at least 6 months in the position. The sampling included 40% of FCO present in the prison during data collection, yielding 295 FCOs. Data were collected via Audio Computer-Assisted Self-Interview. A physical examination of participants was conducted including blood pressure, weight, and waist and hip circumference. The Odds Ratio and confidence intervals for independent factors were estimated.

Results

Hypertension prevalence in correctional officers was 37.9%, (95% CI 32.1-44.0). Hypertension was associated with obesity (95% CI = 1.884-9.947), cardiovascular disease (95% CI = 3.348-16.724), and participation in the specific training course for the relevant position (95% CI = 1.413-9.564).

Conclusions

While findings, except for the last factor, are not novel, this is the first such study conducted in Brazil. Hypertension prevalence among this pool of all female correctional officers is higher than in the average population, and FCOs associate this with the prison environment. Current training does not appear to address this problem. Especially since prison populations are growing in Brazil, this problem needs to be addressed for the health of the FCOs and the prisoners in their care.
