This study highlights that aerobically trained women perform 30-min self-paced work trials ∼2 wk apart with acceptably low variability and their hormonal/ovulatory status and the introduction of greater ambient heat and humidity do not moderate this measurement error.
Preconditioning contractions prevent prolonged force depression and Ca2+-dependent proteolysis of STAC3 after damaging eccentric contractions
Authors: Ashida Yuki , Himori Koichi , Tamai Katsuyuki , Kimura Iori , Yamada Takashi
Published: September 2021

The SH3 and cysteine-rich domain 3 (STAC3) is a skeletal muscle-specific protein that couples membrane depolarization to sarcoplasmic reticulum Ca2+ release. No studies, however, examined the role of STAC3 in protective effects of preconditioning contractions (PCs) against damaging eccentric contractions (ECCs). Here, we demonstrate that PCs may improve recovery from damaging ECCs-induced force depression, in part by an inhibition of Ca2+-dependent proteolysis of STAC3 due to increased membrane permeability and subsequent calpain 1 activation.

Published: September 2021

Aim/Introduction. Obstructive sleep apnea (OSA) is a sleep-related breathing disorder that is characterized by repeated episodes of upper airway occlusion during sleep. The patients with OSA suffered from comprehensive oxidative stress in all systems. OSA might induce type 2 diabetes mellitus (T2DM), a kind of metabolism disorder. In this passage, we are exploring the dose-response relationship between OSA and T2DM. Materials and Methods. We screened four databases (PubMed, Embase, Cochran Library, and CNKI) for the observational studies about the OSA and T2DM. Studies were collected from database establishment to October 2020. We performed a traditional subgroup meta-analysis. What is more, linear and spline dose-response models were applied to assess the association between apnea-hypopnea index (AHI), an indicator to evaluate the severity of OSA, and the risk of T2DM. Review Manager, version 5.3, software and Stata 16.0 were used for the analysis. Result. Seven observational studies were included in the research. We excluded a study in the conventional meta-analysis. In the subgroup analysis, mild-dose AHI increased the risk of T2DM (odds ratio = 1.23, 95% confidence interval = 1.06–1.41,

P

 < 0.05). Moderate-dose AHI increased the risk of T2DM with a higher odds ratio (OR = 1.35, 95% CI = 1.13–1.61,

P

 < 0.05). Moderate-to-severe-dose AHI increased the risk of T2DM with a higher odds ratio (OR = 2.14, 95% CI = 1.72–2.67,

P

 < 0.05). Severe-dose AHI increased the risk of T2DM with a higher odds ratio (OR = 2.19 95% CI = 1.30–3.68,

P

 < 0.05). Furthermore, the spline and linear dose-response meta-analysis results revealed that the risk of T2DM increased with increasing AHI values. Conclusion. Through the dose-response meta-analysis, we found a potential dose-response relationship existed between the severity of OSA and the risk of T2DM. This relationship in our passage should be considered in the prevention of T2DM in the future.

) in telemedicine services, 122 rheumatoid arthritis patients (1.6%) were followed for 1 month to assess change in functional status by modified Health Assessment Questionnaire (mHAQ). Telephonic interviews of the enrolled patients were conducted to determine the level of understanding of advice given by consultants, barriers during the consultation, and satisfaction with teleconsultations for rheumatology clinics. Results. For the native people, language of the clinicians was the main barrier (20%) in telerheumatology. Saving of time and money was observed as beneficial factors for patients. More than three-quarters of all rheumatoid arthritis patients were ready to use teleconsultation in the near future. A similar proportion of patients were in support for the recommendation of these services to other persons. Conclusion. We report the successful use of telemedicine services in the evaluation and management of rheumatic diseases in the current COVID-19 pandemic situation.

Published: September 2021

Road surface defects are crucial problems for safe and smooth traffic flow. Due to climate changes, low quality of construction material, large flow of traffic, and heavy vehicles, road surface anomalies are increasing rapidly. Detection and repairing of these defects are necessary for the safety of drivers, passengers, and vehicles from mechanical faults. In this modern era, autonomous vehicles are an active research area that controls itself with the help of in‐vehicle sensors without human commands, especially after the emergence of deep learning (DNN) techniques. A combination of sensors and DNN techniques can be useful for unmanned vehicles for the perception of their surroundings for the detection of tracks and obstacles for smooth traveling based on the deployment of artificial intelligence in vehicles. One of the biggest challenges for autonomous vehicles is to avoid the critical road defects that may lead to dangerous situations. To solve the accident issues and share emergency information, the Intelligent Transportation System (ITS) introduced the concept of vehicular network termed as vehicular ad hoc network (VANET) for achieving security and safety in a traffic flow. A novel mechanism is proposed for the automatic detection of road anomalies by autonomous vehicles and providing road information to upcoming vehicles based on Edge AI and VANET. Road images captured via camera and deployment of the trained model for road anomaly detection in a vehicle could help to reduce the accident rate and risk of hazards on poor road conditions. The techniques Residual Convolutional Neural Network (ResNet‐18) and Visual Geometry Group (VGG‐11) are applied for the automatic detection and classification of the road with anomalies such as a pothole, bump, crack, and plain roads without anomalies using the dataset from different online sources. The results show that the applied models performed well than other techniques used for road anomalies identification.

Published: September 2021

Purpose. Exercise training is an essential treatment option for patients with chronic heart failure (CHF). However, it remains controversial, which surrogate measures of functional work capacity are most reliable. The purpose of this paper was to compare functional capacity work measured as capillary lactate concentrations area under the curve (AUC) with standard cardiopulmonary exercise testing (CPET) with VO2peak and the 6-minute walk test (6 MWT). Methods. Twenty-three patients in New York Heart Association (NYHA) class II/III with left ventricular ejection fraction (LVEF) <35% were randomised to home-based recommendation of regular exercise (RRE) (controls), moderate continuous training (MCT) or aerobic interval training (AIT). The MCT and AIT groups underwent 12 weeks of supervised exercise training. Exercise testing was performed as standard CPET treadmill test with analysis of VO2peak, the 6 MWT and a novel 30-minute submaximal treadmill test with capillary lactate AUC. Results. All patients had statistically significant improvements in VO2peak, 6 MWT and lactate AUC after 12 weeks of exercise training: 6 MWT (p =0.035), VO2peak (p =0.049) and lactate AUC (p =0.002). Lactate AUC (p =0.046) and 6MWT (p =0.035), but not VO2peak revealed difference between the exercise modalities regarding functional work capacity. Conclusion. 6-MWT and lactate AUC, but not VO2peak, were able to reveal a statistically significant improvement in functional capacity between different exercise modalities.

Published: September 2021

In order to grasp the timing of sun calibration in advance, this paper introduces a high-precision method to predict the solar angle by using the current broadcast time and orbital instantaneous root of the satellite platform. By calculating the sun’s apparent right ascension and apparent declination, the conversion matrix from the geocentric inertial coordinate system to the orbital coordinate system, and the satellite attitude correction matrix, the sun vector in the satellite body coordinate system is obtained. This method is used to predict the sun angle of a sun synchronous orbit in the satellite coordinate system, and the prediction results are compared with the STK simulation results. The results show that the sun angle prediction error of this method is less than ±0.003°. It can meet the requirements of on-orbit solar calibration. The main error sources in the prediction method are analysed.

Ilicis Rotundae Cortex (IRC) consists of the bark of Ilex rotunda Thunb, and its chemical constituents mainly include flavonoid glycosides, phenols, and triterpenoid saponins. In this study, a preliminary analysis was performed to identify and obtain the chemical components from IRC to better control the quality of the medicinal materials and provide a chemical basis for the study of the efficacy of the active components. Simple and efficient sample pretreatment and ultrasonic-assisted extraction methods were used to analyze the mass spectrum fragments and fracture modes in the anion mode by UPLC-Q-TOF-MS/MS. Using a two-step strategy, the neutral loss, diagnostic ions, and characteristic fragments were studied to screen diverse skeletons and substitutions, and the possible compounds were identified by comparison with databases. The representative compounds were compared with the standard, and the mass spectrogram was found to match perfectly. Thus, our findings reveal that this method is feasible and reliable and can be used to analyze the chemical components of IRC. We identified 105 compounds, including 22 triterpenoid saponins, 15 chlorogenic acids, 33 phenylpropanoids and phenylpropanosides, 3 iridoids, 1 flavonoid, 10 lignans, 12 glycosides, and 9 other compounds. This method lays the foundation for further elucidating the pharmacodynamics of IRC and provides a practical method for the identification of IRC.

Published: September 2021

Budd-Chiari syndrome (BCS) is a rare disorder caused by hepatic venous outflow obstruction that can lead to acute liver failure proposing liver transplantation or transjugular intrahepatic portosystemic shunt. However, the transjugular intrahepatic portosystemic shunt is not always successful due to the entire hepatic vein thrombosis while transplantation is not unfailingly feasible. In these situations, the direct intrahepatic portosystemic shunt (DIPS) is a viable alternative that may ameliorate portal hypertension in these patients. We described a case of a 21-year-old male with fulminant hepatic failure owning to BCS with a 4-day history of abdominal pain and nausea. Laboratory workup, including viral, autoimmune etiologies JAK2 mutation, Factor V Leiden, antiphospholipid antibody syndrome, was negative. The patient’s clinical status worsened with hepatic encephalopathy stage II despite administering anticoagulation. Thus, the patient underwent urgently DIPS after unaccessible to the creation of a transjugular intrahepatic portosystemic shunt and impossible to transplantation. The patient’s health was improved and discharged. Fulminant Budd-Chiari is a rare disease to be demanding prompt treatment. While transplantation or transjugular intrahepatic portosystemic shunt is failed, the DIPS is considered an alternative candidate associated with clinical improvement.
Comparison between Original and Reviewed Consensus of European Working Group on Sarcopenia in Older People: A Probabilistic Cross-Sectional Survey among Community-Dwelling Older People
Authors: Ramirez Erik , Salas Rogelio , Bouzas Cristina , Pastor Rosario , Tur Josep A.
Published: September 2021

Introduction: The European Working Group on Sarcopenia in Older People (EWGSOP) published a consensus on sarcopenia in 2010 and updated it in 2019 (EWGSOP2) which included the use of specific cut-off points. The aim was to assess how much prevalence of sarcopenia differed between EWGSOP2 and EWGSOP, as well as the use of specific cut-off points to assess differences in presarcopenia versus probable sarcopenia. Methods: Observational, transversal, and comparative study (n = 1,283 older adults; 57% women). Anthropometrics and handgrip strength were measured, and appendicular skeletal muscle mass equation was defined. Conceptual and methodological definitions of EWGSOP and EWGSOP2 consensus were applied to calculate prevalence of presarcopenia, probable sarcopenia, and sarcopenia. Results: Using cut-off points recommended for European population, prevalence of sarcopenia with EWGSOP2 was lower (−6.6%; p < 0.001) than EWGSOP. The prevalence of probable sarcopenia (EWGSOP2) was higher (+7.8%; p < 0.001) than EWGSOP presarcopenia. The agreement between EGWGSOP and EWGSOP2 was moderated (K = 0.45; IC = 0.40–0.51). Using specific-population cut-off points for muscle strength and appendicular muscle mass, the prevalence of probable sarcopenia with EWGSOP2 was higher (46.5%; p < 0.001) than EWGSOP (1.8%). The agreement between EGWGSOP and EWGSOP2 was moderated (K = 0.48; IC = 0.42–0.52). Conclusion: The new EWGSOP2 consensus underestimates the prevalence of sarcopenia, compared with EWGSOP using conventional cut-off points. The prevalence of presarcopenia with EWGSOP (low muscle mass) was lower than probable sarcopenia (low muscle strength) with the new EWGSOP2. In both cases, agreements between EWGSOP2 and EWGSOP were moderated. Discrepancies between the original and new consensus have implications on the primary health setting for identifying old and new cases for prevention and treatment.

Published: September 2021

O artigo examina o discurso organizacional do movimento pela igualdade de gênero HeForShe/ElesPorElas da ONU Mulheres, com atenção ao debate sobre lugares de fala. Embasando-se na semiótica discursiva paratextual de contextualização sóciohistórica e enunciativa, a análise é feita por meio de três estratégias: 1) contextualização histórica e identidade visual; 2) protagonismo feminino e convite à cooperação masculina; e 3) implementação e alcance da campanha. Evidencia-se que a prática discursiva da ElesPorElas envolve homens como agentes na luta contra o sexismo e se sustenta pelo feminismo visionário.

Background and Purpose:

Computed tomography perfusion imaging allows estimation of tissue status in patients with acute ischemic stroke. We aimed to improve prediction of the final infarct and individual infarct growth rates using a deep learning approach.

Methods:

We trained a deep neural network to predict the final infarct volume in patients with acute stroke presenting with large vessel occlusions based on the native computed tomography perfusion images, time to reperfusion and reperfusion status in a derivation cohort (MR CLEAN trial [Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands]). The model was internally validated in a 5-fold cross-validation and externally in an independent dataset (CRISP study [CT Perfusion to Predict Response to Recanalization in Ischemic Stroke Project]). We calculated the mean absolute difference between the predictions of the deep learning model and the final infarct volume versus the mean absolute difference between computed tomography perfusion imaging processing by RAPID software (iSchemaView, Menlo Park, CA) and the final infarct volume. Next, we determined infarct growth rates for every patient.

Results:

We included 127 patients from the MR CLEAN (derivation) and 101 patients of the CRISP study (validation). The deep learning model improved final infarct volume prediction compared with the RAPID software in both the derivation, mean absolute difference 34.5 versus 52.4 mL, and validation cohort, 41.2 versus 52.4 mL (
P
<0.01). We obtained individual infarct growth rates enabling the estimation of final infarct volume based on time and grade of reperfusion.

Conclusions:

We validated a deep learning-based method which improved final infarct volume estimations compared with classic computed tomography perfusion imaging processing. In addition, the deep learning model predicted individual infarct growth rates which could enable the introduction of tissue clocks during the management of acute stroke.
Presence and Communication in Hybrid Virtual and Augmented Reality Environments
Authors: Li Yue , Ch'ng Eugene , Cobb Sue , See Simon
Published: September 2021

The use of virtual reality (VR) and augmented reality (AR) in connected environments is rarely explored but may become a necessary channel of communication in the future. Such environments would allow multiple users to interact, engage, and share multidimensional data across devices and between the spectrum of realities. However, communication between the two realities within a hybrid environment is barely understood. We carried out an experiment with 52 participants in 26 pairs, within two environments of 3D cultural artifacts: (1) a Hybrid VR and AR environment (HVAR) and (2) a Shared VR environment (SVR). We explored the differences in perceived spatial presence, copresence, and social presence between the environments and between users. We demonstrated that greater presence is perceived in SVR when compared with HVAR, and greater spatial presence is perceived for VR users. Social presence is perceived greater for AR users, possibly because they have line of sight of their partners within HVAR. We found positive correlations between shared activity time and perceived social presence. While acquainted pairs reported significantly greater presence than unacquainted pairs in SVR, there were no significant differences in perceived presence between them in HVAR.
Trends and projection of heavy snowfall in Hokkaido, Japan as an application of self-organizing map
Authors: Inatsu Masaru , Kawazoe Sho , Mori Masato
Published: September 2021

This paper showed the frequency of local-scale heavy winter snowfall in Hokkaido, Japan, its historical change, and its response to global warming using self-organizing map (SOM) of synoptic-scale sea-level pressure anomaly. Heavy snowfall days were here defined as days when the snowfall exceeded 10 mm in water equivalent. It was shown that the SOMs can be grouped into three categories for heavy snowfall days: 1) a passage of extratropical cyclones to the south of Hokkaido, 2) a pressure pattern between the Siberian high and the Aleutian low, and 3) a low-pressure anomaly just to the east of Hokkaido. Groups 1 and 2 were associated with heavy snowfall in Hiroo (located in southeastern Hokkaido) and in Iwamizawa (western Hokkaido), respectively, and heavy snowfall in Sapporo (western Hokkaido) was related to Group 3. The large-ensemble historical simulation reproduced the observed increasing trend in Group 2 and future projection revealed that Group 2 was related to a negative phase of the Western Pacific pattern and the frequency of this group would increase in the future. Heavy snowfall days associated with SOM Group 2 would also increase due to the increase in water vapor and preferable weather patterns in global warming climate, in contrast to the decrease of heavy snowfall days in other sites associated with SOM Group 1.
Precipitation unevenness in gauge observations and eight reanalyses from 1979 to 2018 over China
Authors: Wu Guocan , Li Yun , Qin Shun , Mao Yuna , Wang Kaicun
Published: September 2021

Precipitation is spatially and temporally unevenly distributed. The unevenness of precipitation is crucial for climate change, as well as for water resource management, environmental risk reduction and industrial/agricultural production. In this study, gauge observations and eight reanalysis products are used to examine the unevenness of precipitation from 1979 to 2018 over China. The results show that all the reanalysis datasets can reproduce the spatial pattern of the annual number of wet days and precipitation intensity, as shown in the observations; however, most reanalyses overestimate the former and underestimate the latter. The mean cumulative fractions of the precipitation amount on the wettest 1, 5, and 10 days to annual total are approximately 9.3%, 29.8% and 45.1% in the gauge observations, and are 6.6%±0.8%, 22.1%±2.5% and 34.3%±3.5% in the reanalyses. The mean cumulative fractions of precipitation amount on the wettest 1, 5, and 10 days to annual total displays a small negative trend based on gauge observations over China (-0.06%/decade, -0.10%/decade and -0.10%/decade, respectively), but are positive and stronger in the eight current reanalyses (0.08% ± 0.08%/decade, 0.25%±0.08%/decade and 0.35%±0.10%/decade). The Japanese 55-year reanalysis is the best in quantifying the annual variability of the cumulative fractions of precipitation on the wettest 1, 5, and 10 days over China, while the ERA-Interim is the best in reflecting their trends. The reanalyses agree best with the observations in reflecting cumulative fractions of precipitation in the Yangtze River Basin and the worst in the Northwest China.
A Leadership Development Kōan: Vulnerability as Change Capacity
Authors: Elgayeva Ekaterina
Published: September 2021

How are organizations embracing the emotional complexity of the emerging organizational landscape? More specifically, how do leaders develop the capacity necessary to infuse the organization's emotional circuitry with renewed energy at a time of transformation? In this essay, I posit that vulnerability can be the threshold for change capacity in institutional work, fortifying leaders' developmental trajectories and transforming organizing and organizations. While paradoxical, the regenerative nature of vulnerability yields change capacity requisite of navigating the emotional complexity leaders encounter on their developmental journeys.
Incremental Visual Occlusion During Split-Belt Treadmill Walking Has No Gradient Effect on Adaptation or Retention
Authors: Stone Amanda E. , Hockman Adam C. , Roper Jaimie A. , Hass Chris J.
Published: September 2021

Split-belt treadmills have become an increasingly popular means of quantifying ambulation adaptability. Multiple sensory feedback mechanisms, including vision, contribute to task execution and adaptation success. No studies have yet explored visual feedback effects on locomotor adaptability across a spectrum of available visual information. In this study, we sought to better understand the effects of visual information on locomotor adaptation and retention by directly comparing incremental levels of visual occlusion. Sixty healthy young adults completed a split-belt adaptation protocol, including a baseline, asymmetric walking condition (adapt), a symmetric walking condition (de-adapt), and another asymmetric walking condition (re-adapt). We randomly assigned participants into conditions with varied visual occlusion (i.e., complete and lower visual field occlusion, or normal vision). We captured kinematic data, and outcome measures included magnitude of asymmetry, spatial and temporal contributions to step length asymmetry, variability of the final adapted pattern, and magnitude of adaptation. We used repeated measures and four-way MANOVAs to examine the influence of visual occlusion and walking condition. Participants with complete, compared to lower visual field visual occlusion displayed less consistency in their walking pattern, evident via increased step length standard deviation ( p = .007, d = 0.89), and compared to normal vision groups ( p = .003 d = 0.81). We found no other group differences, indicating that varying levels of visual occlusion did not significantly affect locomotor adaptation or retention. This study offers insight into the role vision plays in locomotor adaptation and retention with clinical utility for improving variability in step control.
New directions in natural theology
Authors: Pickering David
Published: September 2021

This article contrasts natural theology’s vicissitudes in recent centuries with its more promising prospects in contemporary philosophy and theology. It interrogates certain genres of theology regarding their relation to natural theology, focusing on feminist theology, eco-theology, apologetics and the theology of natural law. It concludes with a reflection on the aspects of natural theology that are particularly prominent at present, and asks if the degree of revival currently enjoyed by natural theology may even be the precursor of a greater role in the academy.

Authors: Shin Myung Ho , Baek Samuel , Kim Tae Min , Kim HyunTae , Oh Kyung-Soo , Chung Seok Won
Published: September 2021

Background:

Superior labral anterior and posterior (SLAP) lesions are common injuries in overhead athletes. As a surgical treatment for SLAP lesions, SLAP repair has been traditionally performed. Recently, biceps tenodesis has been performed as an alternative treatment option; however, there is no review for outcome comparisons between these 2 procedures in overhead athletes.

Purpose:

The aim of this study was to compare the outcomes of SLAP repair versus biceps tenodesis, especially in overhead athletes with SLAP lesions.

Study Design:

Systematic review and meta-analysis; Level of evidence, 4.

Methods:

An electronic literature search was performed in Medline, Embase, Scopus, and the Cochrane Library. The studies were appraised using the Methodological Index for Non-randomized Studies (MINORS) tool. Studies that had a minimum follow-up of 2 years, included only patients with SLAP lesions without other major shoulder pathologies, and included only patients who engaged in overhead sports were included. The functional outcomes of the American Shoulder and Elbow Surgeons (ASES) score, rate of return to sport, rate of return to preinjury level of sport, and complication rate were subjected to meta-analysis.

Results:

A total of 332 articles were identified, and 13 were included in the systematic review. Even though the postoperative ASES scores were slightly higher in the biceps tenodesis group than in the SLAP repair group, no statistically significant differences were found between the groups (biceps tenodesis, 95% CI = 91.71-96.75, I2 = 0.00; SLAP repair, 95% CI = 85.47-94.46, I2 = 16.3; P = .085) The rate of return to sport and the return to preinjury level of sport were slightly higher in the biceps tenodesis group than in the SLAP repair group; however, in meta-analysis these factors did not reach statistical significance (return to sport: biceps tenodesis, 95% CI = 0.66-0.91, I2 = 0.00; SLAP repair, 95% CI = 0.68-0.93, I2 = 70.23; P = .94) (return to preinjury level of sport: biceps tenodesis, 95% CI = 0.61-0.89, I2 = 17.78; SLAP repair, 95% CI = 0.53-0.82, I2 = 58.07; P = .37). The biceps tenodesis group showed a lower complication rate compared with the SLAP repair group without statistical significance (biceps tenodesis, 95% CI = 0.013-0.145, I2 = 0.00; SLAP repair, 95% CI = 0.049-0.143, I2 = 0.00; P = .25).

Conclusion:

The results of biceps tenodesis, compared with SLAP repair, were not inferior in the surgical treatment of overhead athletes with SLAP lesions with regard to the ASES score, rate of return to sport, rate of return to preinjury level of sport, and complication rate. Further high-level, randomized controlled studies are needed to confirm this result.

Published: September 2021

Background:

Purpose:

In response to the pandemic, some public health agencies recommend the wearing of surgical masks in indoor spaces including radiology common reporting rooms. We aim to demonstrate whether mask wearing may lead to increased errors incidence in radiology reports.

Materials and Methods:

Our prospective studywas conveyed in 2 parts. Firstly, the participants were surveyed if they believed that mask affected dictation. Then participants performed a dictation: they read artificial radiology reports using a commercial voice recognition (VR) system. They performed this task 5 times, each time donning a different mask in random order: a surgical mask, surgical visor, N-95, combination of 2 surgical masks and no mask. Error rates were compared with the Friedman test followed by pairwise Wilcoxon with bootstrapping. Multivariate Poisson regression was performed to test for interaction effects between potential predictors.

Results:

52 members of an academic radiology department participatedin the study (January – March 2021) . 65.4% of survey participants did not think or were not sure whether mask wearing could affect dictation process. Treating the no-mask condition as baseline, our study found that mean error rates significantly increased up to 2 times the baseline rate when a surgical mask, surgical visor, N-95 or a combination of 2 masks was donned (p < 0.0001). No significant differences in error rates were found between the different mask types (p > 0.05). Error rates were higher for participants with shorter VR training time (p < 0.0001) or who were non-native English speakers (p < 0.0001). There were no interaction effects between mask type, VR training time or English nativity, suggesting these variables to be independent predictors for error rate. Academic rank did not significantly affect the error rate.

Conclusion:

radiologists underestimate the influence of masks on dictation accuracy. mask wearing may lead to significant increase in dictational errors
Phytopathogen transmitted from plant to human causing peritoneal dialysis-associated peritonitis
Authors: Jaroenpattrawut Bunpring , Poonvivatchaikarn Ussanee , Kanjanabuch Talerngsak , Eiam-Ong Somchai
Published: September 2021

We report the first case of peritoneal dialysis (PD)-associated peritonitis due to Sporothrix schenckii, a thermally dimorphic black fungus transmitted from epiphytotic disease. The patient presented with PD-associated peritonitis and fungal colonisation inside the PD catheter’s lumen after an exposing ‘wet contamination’ event with a phytopathogen 11 days prior to the onset of infection. The human pathogen and phytopathogen were confirmed the same species by nucleotide sequences of the internal transcribed spacer and large subunit regions of the ribosomal RNA gene. A ‘wet contamination’ should be closely monitored for an extended period, and a broader spectrum of organisms might lead to peritonitis, particularly in centres with a high prevalence of fungal infection. PD patients and their caregivers should have periodic retraining of aseptic technique and personnel hygiene. We also recommend a long course of antifungal medication in eradicating peritoneal sporotrichosis to prevent unfavourable outcomes and relapsing peritonitis from this organism.

Published: September 2021

Background

Bladder cancer (BCa) is a common genitourinary malignancy with higher incidence in males. Long intergenic non-protein coding RNA 265 (LINC00265) is identified as an oncogene in many malignancies, while its role in BCa development remains unknown.

Purpose

To explore the functions and mechanism of LINC00265 in BCa

Research Design

Reverse transcription quantitative polymerase chain reaction was performed to examine LINC00265 expression in BCa cells. Cell counting kit-8 assays, colony formation assays, TdT-mediated dUTP Nick-End Labeling assays, and Transwell assays were conducted to examine BCa cell viability, proliferation, apoptosis, and migration. Luciferase reporter assays and RNA immunoprecipitation assays were carried out to explore the binding capacity between miR-4677-3p and messenger RNA fibroblast growth factor 6 (FGF6) (or LINC00265). Xenograft tumor model was established to explore the role of LINC00265 in vivo.

Results

LINC00265 was highly expressed in BCa cells. LINC00265 knockdown inhibited xenograft tumor growth and BCa cell viability, proliferation and migration while enhancing cell apoptosis. Moreover, LINC00265 interacted with miR-4677-3p to upregulate the expression of FGF6. FGF6 overexpression reversed the suppressive effect of LINC00265 knockdown on malignant phenotypes of BCa cells.

Conclusions

LINC00265 promotes the viability, proliferation, and migration of BCa cells by binding with miR-4677-3p to upregulate FGF6 expression.
Knowledge of students of the exceptions and limitations clause in copyright administration in academic libraries in Ghana
Authors: Adu Theresa L. , Van der Walt Thomas B.
Published: September 2021

Copyright exceptions and limitations, which allow information consumers the right to use copyrighted materials without necessarily obtaining permission from or payment to the rightsholder, promote advances in the arts and sciences. Poor knowledge of copyright laws results in improper use of copyrighted materials. However, the extent to which academic library users in Ghana know about the exceptions and limitations, as well as their understanding of permissible use of information in the Copyright Act 690, 2005 of Ghana are not known. The sequential mixed methods approach was employed to collect data from 530 postgraduate students from two public and two private universities in Ghana to assess their knowledge of copyright exceptions and limitations, as well as their understanding of permissible use of information in Copyright Act 690, 2005 whilst using the services of their libraries. The study shows that students were poorly knowledgeable about the various applications of the exceptions and limitations clause in the copyright laws of Ghana: students were either indifferent (i.e. ‘neutral’), or ‘disagree’, and ‘strongly disagree’ on whether the Copyright Act 690, 2005 had clauses on exceptions and limitations on various uses of information such as for ‘Private copying’, for ‘Quotations’ or ‘For the benefit of persons with disability’. Over 50% of respondents were not sure that the copyright laws of Ghana had provisions for permissible use of information. Age and gender of respondent significantly influenced these responses: older students 46 years and above, and females, were more knowledgeable compared to younger students and males respectively about exceptions and limitations for ‘Private copying’, and ‘For the benefit of people with disability’ in the copyright laws of Ghana. Policymakers in Ghana should therefore adopt youth- and gender-focus strategies in copyright education for efficient administration of copyright laws in academic libraries.

Published: September 2021

Background

Breast cancer survivor goes through a period of needs in their post-treatment daily life. Relatively few studies have been conducted to understand the unmet needs among breast cancer survivors in Bangladesh. Recognize and measure patterns and predictors of unmet needs of breast cancer patients was the aim of the study.

Objective

To identify and measure patterns and predictors of unmet needs of breast cancer patients in Bangladesh.

Method

A cross-sectional study among 138 breast cancer patients; conveniently selected from two public and two private cancer institutes. Face-to-face interview for data collection and medical record review for checklist was done. Unmet needs have been determined by the supportive care needs survey short form 34 scale. Logistic regression analyses were performed to identify the predictors of unmet needs.

Results

The study indicated the top 10 moderate-to-high needs; among which the top five needs were from the information need domain. Surprisingly, private cancer treatment centers were identified as a significant predictor for unmet needs. Patients from private cancer institutes reported more explanation needs as well as needs with their physical and daily living and sexuality. Furthermore, the type of treatment like patient receiving combine treatment therapy reported more need for help compared to the patient receiving chemotherapy alone. Moreover, housewives reported the low need for patient care and support systems as a result of their reluctant behavior towards their health.

Conclusion

Individual’s unmet need assessment should be a part of every treatment protocol of breast cancer for a better treatment outcome.

Published: September 2021

Purpose:

To study inner retinal neurodegeneration in Diabetes Mellitus using spectral domain optical coherence tomography (OCT).

Methods:

This cross-sectional study included 40 eyes of age matched healthy subjects (group N), 40 eyes of diabetic patients without diabetic retinopathy (group D) and 160 eyes with diabetic retinopathy (group R) having 40 each in subgroups R1 (mild), R2 (moderate), R3 (severe/very severe) non-proliferative stages and R4 (proliferative stage). Spectral domain OCT was used to measure the ganglion cell-inner plexiform layer (GC-IPL) thickness and retinal nerve fibre layer (RNFL) thickness.

Results:

The average GC-IPL thickness was significantly lower, both in groups D ( p = 0.005) and R ( p = 0.009), when compared with group N. The minimum GC-IPL thickness was also significantly lower in groups D ( p < 0.001) and R ( p < 0.001). There was no statistically significant difference in the average RNFL thickness among the groups. The minimum RNFL thickness was significantly lesser in group D ( p = 0.027). The minimum RNFL thickness had a strongly negative correlation with the severity of DR ( R = −0.828; p = 0.042). The thinning of both GC-IPL and RNFL was most pronounced in subgroup R4.

Conclusion:

There is a significant reduction in the GC-IPL thickness and the RNFL thickness in diabetes even before the onset of DR. The changes in both GC-IPL thickness and RNFL thickness are most pronounced after the onset of PDR. There is a strongly negative correlation between the minimum RNFL thickness with the severity of DR.
