Background: As the incidence of COVID-19 is increasing, the Bangladesh government has announced a countrywide shutdown instead of a lockdown. Consequently, front-line healthcare workers, particularly nurses, are confronting more challenging situations at work.
Objective: This study aimed to explore front-line nurses’ experiences caring for patients with COVID-19 in Dhaka, Bangladesh.
Methods: A qualitative descriptive study was conducted among front-line nurses caring for patients with COVID-19. Twenty nurses were purposively chosen from January to March 2021 to participate in semi-structured online interviews. Interviews on audio and video were collected, analyzed, interpreted, transcribed verbatim, and verified by experts. Thematic analysis was used.
Results: Nine themes emerged and were grouped into negative and positive experiences. The themes of negative experiences include lack of necessary medical equipment, use of non-standard personal protective equipment, work overload, long working hours, poor working environment, and lack of quality of nursing care. The positive experiences include feeling self in a patient position, nurses’ coping strategy in COVID-19 patient care, and establishing emotional control.
Conclusion: The study results encourage national and international health care professionals to cope with adverse working environments. Also, the findings provide nurses with techniques for dealing with any critical situation, controlling patients’ emotions, and how empathy increases self-confidence and patient care. The research should also be used to enhance government policy, nursing council policy, ministry of health policy, and other healthcare agencies.
Brewing Efficacy of Non-Conventional Saccharomyces Non-cerevisiae Yeasts
Authors: Bruner James , Marcus Andrew , Fox Glen 
Published: September 2021

Consumer demands for new sensory experiences have driven the research of unconventional yeasts in beer. While much research exists on the use of various common Saccharomyces cerevisiae strains as well as non-Saccharomyces yeasts, there exists a gap in knowledge regarding other non-cerevisiae Saccharomyces species in the fermentation of beer, in addition to S. pastorianus. Here, five distinct species of Saccharomyces from the UC Davis Phaff Yeast Culture Collection, as well as one interspecies hybrid from Fermentis, were chosen to ferment 40 L pilot-scale beers. S. kudriavzevii, S. mikatae, S. paradoxus, S. bayanus, and S. uvarum yeasts were used to ferment wort in duplicate pairs, with one fermenter in each pair receiving 10 g/L dry-hop during fermentation. Analytical measurements were made each day of fermentation and compared to controls of SafAle™ US-05 and SafLager™ W 34/70 for commercial brewing parameters of interest. Finished beers were also analyzed for aroma, taste, and mouthfeel to determine the flavor of each yeast as it pertains to brewing potential. All beers exhibited spicy characteristics, likely from the presence of phenols; dry-hopping increased fruit notes while also increasing perceived bitterness and astringency. All of the species in this study displayed great brewing potential, and might be an ideal addition to beer depending on a brewery’s desire to experiment with flavor and willingness to bring a new yeast into their production environment.

High-fat diet (HFD) consumption has been linked to dyslipidemia, low-grade inflammation and oxidative stress. This study investigated the effects of a mixed formulation with Limosilactobacillusfermentum 139, L. fermentum 263 and L. fermentum 296 on cardiometabolic parameters, fecal short-chain fatty acid (SCFA) contents and biomarkers of inflammation and oxidative stress in colon and heart tissues of male rats fed an HFD. Male Wistar rats were grouped into control diet (CTL, n = 6), HFD (n = 6) and HFD with L. fermentum formulation (HFD-Lf, n = 6) groups. The L.fermentum formulation (1 × 109 CFU/mL of each strain) was administered twice a day for 4 weeks. After a 4-week follow-up, biochemical parameters, fecal SCFA, cytokines and oxidative stress variables were evaluated. HFD consumption caused hyperlipidemia, hyperglycemia, low-grade inflammation, reduced fecal acetate and propionate contents and increased biomarkers of oxidative stress in colon and heart tissues when compared to the CTL group. Rats receiving the L. fermentum formulation had reduced hyperlipidemia and hyperglycemia, but similar SCFA contents in comparison with the HFD group (p < 0.05). Rats receiving the L. fermentum formulation had increased antioxidant capacity throughout the colon and heart tissues when compared with the control group. Administration of a mixed L. fermentum formulation prevented hyperlipidemia, inflammation and oxidative stress in colon and heart tissues induced by HFD consumption.
Fifty Generations of Amitosis: Tracing Asymmetric Allele Segregation in Polyploid Cells with Single-Cell DNA Sequencing
Authors: Vitali Valerio , Rothering Rebecca , Catania Francesco 
Published: September 2021

Amitosis is a widespread form of unbalanced nuclear division whose biomedical and evolutionary significance remain unclear. Traditionally, insights into the genetics of amitosis have been gleaned by assessing the rate of phenotypic assortment. Though powerful, this experimental approach relies on the availability of phenotypic markers. Leveraging Paramecium tetraurelia, a unicellular eukaryote with nuclear dualism and a highly polyploid somatic nucleus, we probe the limits of single-cell whole-genome sequencing to study the consequences of amitosis. To this end, we first evaluate the suitability of single-cell sequencing to study the AT-rich genome of P. tetraurelia, focusing on common sources of genome representation bias. We then asked: can alternative rearrangements of a given locus eventually assort after a number of amitotic divisions? To address this question, we track somatic assortment of developmentally acquired Internal Eliminated Sequences (IESs) up to 50 amitotic divisions post self-fertilization. To further strengthen our observations, we contrast empirical estimates of IES retention levels with in silico predictions obtained through mathematical modeling. In agreement with theoretical expectations, our empirical findings are consistent with a mild increase in variation of IES retention levels across successive amitotic divisions of the macronucleus. The modest levels of somatic assortment in P. tetraurelia suggest that IESs retention levels are largely sculpted at the time of macronuclear development, and remain fairly stable during vegetative growth. In forgoing the requirement for phenotypic assortment, our approach can be applied to a wide variety of amitotic species and could facilitate the identification of environmental and genetic factors affecting amitosis.

The objects of research are oligomers-hardeners obtained by aminolysis of secondary polyethylene terephthalate (PET) and polycarbonate (PC) household waste with an aliphatic amine (PEP).The epoxy-diane resin of the ED-20 brand was chosen as the binder cured by the obtained oligomers due to its availability, good properties, acceptable viscosity, and wide applicability. The study of some parameters of the curing of thermosetting resin by industrial and synthesized hardeners is carried out.The gelation times at elevated temperatures (in the range from 50 to 100°C) and the activation energies of epoxy compositions were determined, and the conversion of epoxy groups during curing at room temperature was studied. The analysis of the obtained data showed that the structural features of macromolecules caused by the introduction of PET and PC fragments have a negligible effect on the activation energy and affect only when cured at room temperature and increase the viability of the compositions, while the gelation time at elevated temperatures in the case of all the studied hardeners is almost the same.
Proactive Alliance: Combining policing and counselling psychology
Authors: Gill Charlotte , Mastoras Molly C. 
Published: September 2021

The philosophy of community-oriented policing (COP) has been widely adopted by police departments around the world and has important benefits, such as improving community members’ satisfaction with police and their perceptions of police legitimacy. However, implementing COP is challenging. Police departments report difficulties obtaining the support of officers on the ground and knowing how best to engage communities—which often contain multiple, overlapping, and sometimes competing groups within the same geographic area—in effective problem-solving and crime prevention.
This article describes Proactive Alliance, an innovative training program that draws from criminological theory andevidence-based principles in counselling psychology to teach police officers specific, immediately applicable techniques to establish rapport and long-term working relationships with community stakeholders. The training addresses two key challenges of COP: building meaningful collaboration across diverse communities and empowering frontline officers to become change agents in pursuit of the “co-production” of public safety. It builds on the original theory of broken windows policing, which emphasized the importance of harnessing police officers’ personalities to facilitate successful community engagement and crime prevention, and provides practical tools based on those used by mental health professionals to enable officers to engage in active listening, to connect, and to problem-solve with the community while protecting their own well-being. We conclude by describing the potential of Proactive Alliance to strengthen COP and evidence-based policing more broadly.

Published: September 2021

Introduction: To address the increase in opioid-related overdoses and deaths in Canada the Good Samaritan Drug Overdose Act (GSDOA) was enacted in May 2017. The GSDOA aims to reduce concerns of police attending overdose events and encourage bystanders to call emergency services. This study explores GSDOA awareness and understanding and the factors associated with GSDOA awareness among people who use drugs (PWUD).
Methods: A cross-sectional drug and harm reduction service use survey containing GSDOA-specific questions wasconducted from October to December 2019 at 22 harm reduction supply distribution sites across British Columbia.Descriptive analysis and multivariable logistic regression were conducted to assess correlates of GSDOA awareness.
Results: Overall, 54.2% (n = 315) of the eligible study sample (n = 581) reported being aware of the GSDOA. Of respondents reporting awareness, 45.2% and 61.3%, respectively, had a full understanding of when and to whom the GSDOA provides legal protection. In the multivariable model, GSDOA awareness was significantly associated with respondents identifying as cis-men (adjusted odds ratio (AOR) = 2.03 [95% CI: 1.30–3.19]); and those who obtained harm reduction supplies frequently (at least a few times/week) compared with those who did not obtain supplies or obtained them less frequently (AOR = 1.78 [95% CI: 1.14–2.76]).
Conclusion: More than 2 years after its introduction, approximately half of harm reduction site clients reported being aware of the GSDOA, and, of these, less than two-thirds had a complete understanding of who is legally protected by the GSDOA. Future GSDOA knowledge dissemination should target PWUD who are less engaged with harm reduction services to improve GSDOA awareness and understanding.
