Authors: Antoine Colette M. , Morrison Belinda F. , Brooks Michael E. 
Published: February 2021

Aims: This study aimed to determine the prevalence rates of transrectal ultrasound-guided prostate biopsy-related complications among patients receiving treatment at the large tertiary-care urology clinic of Kingston Public Hospital (KPH), Jamaica.
Study Design: Prospective cohort study.
Place and Duration of Study: Kingston Public Hospital (KPH), Jamaica from July 2018 to April 2019.
Methodology: Our study population included men who underwent prostate biopsy at KPH. Data on demographics and clinical characteristics were collected using purpose-designed questionnaires from consenting patients who underwent prostate biopsy during the stated period. Patients were then followed up for complications 30 days post biopsy. Details regarding hospitalization due to biopsy-related complications were obtained from the medical records.
Results: Data from 185 men were included in the final analysis. Among the patients biopsied, 49% were diagnosed with prostate cancer, while 72% experienced at least one complication, mainly non-infectious complications such as hematuria (46%), lower urinary tract symptoms (24%), rectal bleeding (23%), hematospermia (9%), and urinary retention (16%). Overall, a 15% risk of developing infectious complications was observed, with 9% experiencing fever and 3% experiencing both urinary tract infection and epididymo-orchitis. Our data showed a 6% hospitalization rate within 30 days, with all available records suggesting infectious complications. One death from a prostatic abscess was noted. The present study showed that most prostate biopsy complications were minor. Moreover, although bleeding and infectious complications as well as hospitalization rates were consistent with those reported in larger series, our population experienced a slightly higher mortality and urinary retention rate.
Conclusion: Overall, our results showed that prostate biopsies performed within our institution are generally safe and well tolerated. Nonetheless, further studies are needed to determine whether morbidity of the procedure remains acceptable.

Authors: Souiyah Miloud 
Published: February 2021

Finite Element Method (FEM) of failure analysis was developed on automobile crankshaft, to determine the stress distribution and the fatigue life, by using ANSYS software. Further, an analytical analysis is applied, Measure the crankshaft stress life. A study was performed on some of the Honda CR-V engine components, specifically are crankshaft, the connecting rod, and the piston. Upon the finite element analysis, it was found that the fillet areas of the crankshaft are the most critical locations where high stresses were generated in these areas. Moreover, with/without considering torsional force acting on the crankshaft does not appear to have any major effects on the stress experience by the crankshaft. In addition, the location where the crack initiated, and fatigue failure starts is located at one of the crankpin journal fillet areas. Indeed, the crankshaft critical areas are mostly affected by uniaxial stress. Moreover, the prediction of the crankshaft fatigue life by using the strain-life theory gives the overall most conservative fatigue life results.
Human Resource Management Practices, Organisation Citizenship Behaviour and Turnover Intentions in Public Universities: The Mediating Role of Job Satisfaction
Authors: Tumwesigye Godfrey , Onen David , Musaazi John C. S. 
Published: February 2021

Aims: The purpose of this paper was to examine the relationships between human resource management practices (HRMPs) and employee outcomes of organizational citizenship behaviour (OCB) and turnover intentions among employees of Public Universities in Uganda, mediated by job satisfaction.
Design/Methodology: The study adopted a cross-sectional, quantitative approach. A sample of 479 academic and non-academic staff was drawn from three public universities in Uganda. SPSS (v20) and AMOS (v20) were used to conduct correlation and structural equation modelling techniques to test the hypotheses.
Results: The results show that job satisfaction is positively related with HRMPs (β =.588, p<.001). The results also show that OCB is positively related to HRMPs (β =.226 p<.01) and job satisfaction (β =.210; p<.01) while turnover intention is negatively influenced by HRM practices (β = -.124, p<.05). The results further show that job satisfaction partially mediates the positive relationship between HRMPs and OCB. Job satisfaction also partially mediates the negative relationship between HRMPs and turnover intentions. This study contributes to the HRM body of knowledge by finding further support for the mediation effects of job satisfaction on the relationships between HRMPs and OCB and between HRMPs and turnover intentions in public universities in Uganda.
Conclusion: The implication of this study is that in order to boost OCB and reduce turnover intentions among employees of public universities in Uganda, managers should employ HRMPs practices that lead to job satisfaction. Limitations and directions for future research are outlined.

Published: February 2021

Arenaviruses are enveloped viruses containing a segmented, negative, and ambisense single‐stranded RNA genome wrapped with a nucleoprotein (NP). The NP is the most abundant viral protein in infected cells and plays a critical role in both replication/transcription and virion assembly. The NP associates with RNA to form a ribonucleoprotein (RNP) complex, and this implies self‐assembly while the exact structure of this polymer is not yet known. Here, we report a measurement of the full‐length Mopeia virus NP by negative stain transmission electron microscopy. We observed RNP complex particles with diameter 15 ± 1 nm as well as symmetric circular heptamers of the same diameter, consistent with previous observations.

Published: February 2021

ObjectiveAlthough hydroxychloroquine/chloroquine (HCQ/CQ) form the cornerstone of systemic lupus erythematosus (SLE) treatment, not all patients receive this, which may contribute to disparities in outcomes. The present study was undertaken to investigate factors associated with first dispensing of HCQ/CQ.MethodsUsing Medicaid insurance claims from 2000 to 2010, we identified individuals ages 18–65 years with incident SLE (≥3 SLE International Classification of Diseases, Ninth Revision codes separated by ≥30 days without prior SLE codes or HCQ/CQ use for 24 months). The primary outcome was first dispensing of HCQ/CQ within 24 months of the first SLE code. We used Cox proportional hazards regression models to examine the association between sociodemographic factors, comorbidities, health care utilization, and medication use and HCQ/CQ dispensing within 24 months of diagnosis.ResultsWe identified 9,560 Medicaid beneficiaries with incident SLE; 41% received HCQ (n = 3,949) or CQ (n = 14) within 24 months of diagnosis. Younger patients were more likely to receive HCQ/CQ. Black, Asian, Hispanic, and American Indian/Alaska Native individuals were more likely to receive HCQ/CQ than White individuals. Alcohol and nicotine use, chronic pain, diabetes mellitus, and end‐stage renal disease were associated with lower dispensing. Appointments and preventive care services were associated with higher rates, and more hospitalizations with lower rates.ConclusionOnly 41% of Medicaid beneficiaries with SLE received HCQ/CQ within 24 months of diagnosis. Greater outpatient and preventive care increased receipt. All non‐White race/ethnicities had higher rates of first dispensing. Time to initial HCQ/CQ dispensing may not explain racial/ethnic disparities in adverse outcomes, highlighting the need to consider other care quality‐related issues and medication adherence challenges.

Published: February 2021

AbstractAqueous hybrid Na–Zn ion batteries (ASZIBs) are promising for large‐scale energy storage due to their low cost and potential for high output voltage. However, most ASZIBs show limited discharge voltage (<2.0 V) and capacity (<100 mAh g–1) due to inefficient usage of the dual ions. In this study, a novel large‐electrochemical‐window “water‐in‐gel” electrolyte based CuHCF‐CNT/Zn Na–Zn hybrid battery is proposed, which achieves a high extraction voltage of Na ion (2.1 V vs Zn/Zn2+), together with a large discharge specific capacity (260 mAh g–1) thanks to the Zn‐ion insertion, delivering a superior energy density of 440 Wh kg–1. The hybrid battery also shows a high capacity retention of 96.8% after 450 cycles. Moreover, an ultrahigh discharge capacity of 1250 mAh g–1 is achieved when further coupled with the Zn‐O2 reaction, delivering the promising application of ion intercalation and metal–air hybrid battery.

Published: February 2021

AbstractChimeric antigen receptor (CAR) T cells exhibit promising results for cancer immunotherapy. However, the clinical success is still restricted to certain types of blood cancers, while in solid tumors the clinical activity is modest and potential toxicities remain a concern. There are various barriers that prevent CAR T cells from combating solid tumors. Therefore, distinct strategies have been explored to augment CAR T cell proliferative capacity, persistence, and effector function. Altering the tumor microenvironment, and in particular its physiochemical properties and immunosuppressive milieu, is of great significance to facilitate CAR T cell therapy. In this article, emerging strategies implemented to overcome the barriers of CAR T cell therapy in solid tumors are reviewed. Enhancing infiltration, activation, and persistence of CAR T cells has been addressed in several preclinical models. The future development of this field to promote innovation and clinical translation is also discussed.

AbstractLayered MoO3 represents a promising cathode for aqueous rechargeable Zn‐ion batteries, but the implementation of this material is limited due to the low conductivity and poor structural stability. A 30 m ZnCl2 water‐in‐salt electrolyte (WISE) is introduced to a MoO3 nanobelt cathode for the first time, significantly increasing the stability of MoO3 cathodes compared to those in 3 m ZnSO4 and 3 m ZnCl2. The Zn/MoO3 cell in WISE unambiguously demonstrate significantly improved rate performance delivering 349, 253, and 222 mAh g−1 at 100, 500, and 1000 mA g−1, denoting a 12× capacity increase of those achieved in 3 m electrolytes at 1000 mA g−1. A capacity retention rate of 73% is achieved after (dis)charging at 100 mA g−1 for 100 cycles, and no obvious capacity fading is observed at higher current densities of 500 mA g−1 and 2 A g−1. Specifically, the data suggest that the drastic fading in 3 m electrolytes can be attributed to the parasitic surface deposits on Zn originated from Mo dissolution and H2 formation due to Zn corrosion and hydrogen evolution reaction, which are significantly suppressed in the WISE. The direct visualization of these side reactions is achieved for the first time in the Zn‐MoO3 system, using an in situ optoelectrochemical measurement.

AbstractIn the era of the Internet of Things, wearable technologies are expected to become an indispensable part of daily life. In recent times, highly sensitive, flexible, and stretchable electronic gas sensors are gaining tremendous interest due to their applicability in wearable electronics applications. The construction of wearable gas sensors are reviewed for real‐time, highly sensitive, and selective detection of hazardous gases at room temperature (RT) that can be laminated onto a human body or integrated with body‐worn textile or other consumer products, utilizing carbon nanomaterials, conductive polymers, 2D nanostructured materials, and their composites. Sensing materials, transduction techniques, and substrates for high‐performance wearable gas sensing are discussed in detail. The critical challenges for future development of wearable gas sensors are presented. Wearable gas sensors are believed to have great potential in environmental monitoring, healthcare, public safety, security, as well as food quality monitoring.
MCaHxF3−x (M = Rb, Cs): Synthesis, Structure, and Bright, Site‐Sensitive Tunable Eu2+ Luminescence

Published: February 2021

AbstractWith increasing interest in mixed‐anionic hydrides, a number of interesting properties have been reported. Here, the structural and optical properties of (Eu2+‐doped) MCaH3–MCaF3 (M = Rb, Cs) are investigated. For M = Rb, a complete hydride–fluoride solid solution series is found and for M = Cs, the known solid solution series (0 ≤ x ≤ 1.70) can be extended to x = 3. In case of Cs, a very bright luminescence emission is observed in Eu2+‐doped samples, whereas the luminescence is fairly weak in Rb based compounds. With increasing hydride content, a shift of the emission color from cyan‐green to red can be observed. In contrast to earlier reports for mixed fluoride–hydride host, the redshift is not a gradual shift of a single broad emission band, but the appearance of new narrow emission bands on the low energy side, which are assigned to the occupation of sites with higher hydride content. Consequently, this finding represents the first example in a mixed anionic hydride with a site‐sensitive emission for sites with locally varying hydride content in the first coordination sphere and may serve as a general example for emission color tuning taking advantage of mixed‐anionic compounds.

Published: February 2021

AbstractRemoving SO2 and NOx released from middle and small‐scaled coal‐burning boiler is one important strategy for air pollution control. Herein, we first report a novel process on simultaneous eliminating SO2 and NOx at low temperature, by employing large scale and cheap sources of phosphorus sludge and phosphate rock slurry. The results showed that 100% desulfurization and denitrification efficiency can be obtained, and there exhibited a significant mutual‐promoting effect between SO2 and NOx abatement processes. Based on characterizations and theoretical calculation results, it was found that the active substances produced by the interaction of sulfur and nitrogen species played a significant role in promoting the removal of SO2 and NOx. Compared with traditional purification technology, this process can achieve simultaneous desulfurization and denitrification with no discharge of secondary pollutants, and can be regarded as a new and economic technology for efficient removal of SO2 and NOx in industrial scale.
Condensed tannins in the diet of folivorous diademed sifakas and the gap between crude and available protein
Authors: Thurau Emma G. , Rahajanirina Andry Narcisse , Irwin Mitchell T. 
Published: February 2021

AbstractTannins, a type of plant secondary metabolite, are well‐known for their ability to precipitate proteins and thereby reduce the protein available to consumers. Most primate studies have focused on condensed tannins (CTs) as they were thought to be the most effective type of tannin at preventing protein acquisition, but there is growing recognition that other types of tannins can bind to proteins, suggesting the division among tannin types is not as clear‐cut as previously thought. Although previous studies have documented the presence of CTs in primate diets and primates' behavioral responses to them, our understanding of tannins remains limited because few researchers have used Sephadex column purification to accurately determine tannin concentrations, and few have used in vitro assays to determine available protein content and the tannins' effectiveness in binding protein. In this study, we documented diademed sifaka (Propithecus diadema) diet from June to August 2018 at Tsinjoarivo, Madagascar (in two forests with varying degrees of habitat disturbance) and quantified CT concentration and actual available protein in foods. Eleven of the fourteen top foods tested contained CTs (concentrations: 4.8%–39.3% dry matter). An in vitro assay showed available protein was strikingly low in six of the eleven top foods (e.g., little to no apparent available protein, despite high crude protein). Overall, our findings suggest sifakas acquire less protein than previously recognized and probably have adaptations to counteract tannins. Such studies of available protein are critical in understanding dietary constraints on sifaka populations and the evolution of their diet choice strategies; despite the conventional wisdom that leaves are protein‐rich, folivorous primates may indeed be protein‐limited. However, further studies are necessary to determine if sifakas have counter‐adaptations to tannins, and if they absorb more protein than our analyses suggest, perhaps receiving protein that we were unable to detect with the current techniques (e.g., pollen).
Passive acoustic monitoring of the diel and annual vocal behavior of the Black and Gold Howler Monkey
Authors: Pérez‐Granados Cristian , Schuchmann Karl‐Ludwig 
Published: February 2021

AbstractPassive acoustic monitoring, when coupled with automated signal recognition software, allows researchers to perform simultaneous monitoring at large spatial and temporal scales. This technique has been widely used to monitor cetaceans, bats, birds, and anurans but rarely applied to monitor primates. Here, we evaluated the effectiveness of passive acoustic monitoring and automated signal recognition software for detecting the presence and monitoring the roaring behavior of the Black and Gold Howler Monkey (Alouatta caraya) over a complete annual cycle at one site in the Brazilian Pantanal. The diel pattern of roaring activity was unimodal, with high vocal activity around dawn. The howler monkey showed a clear seasonal pattern of roaring activity, with most of the roars detected during the wet season (74.9%, peak activity during November and December). The maximum vocal activity occurred during the period of maximum flowering and fruit production in the study area, suggesting a potential role of roaring in defending major feeding sites, which is in agreement with the findings of previous studies on the species. However, we cannot rule out the possibility that roaring may serve different purposes. Vocal activity was negatively associated with relative air humidity, which might be related to lower vocal activity on wetter and rainy days, while vocal activity was not related to minimum air temperature. Automated signal recognition software allowed us to detect the species in 89% of the recordings in which it was vocally active, but with a reduced time cost, since the time investment for data analyses was 2% of recording time. The good performance of the recognizer might be related to the long and loud roars of the howler monkey. Further research should be performed to evaluate the effectiveness of automated signal recognition for detecting the calls of different species of primates and under different environmental conditions.
