Em 2019 e 2020, coordenamos dois projetos de Extensão que se voltavam à temática antirracista no (nome do local do projeto). Os projetos tiveram como base metodológica a análise da literatura de escritoras negras brasileiras. Este artigo é resultado de reflexões advindas com os projetos. Defendemos que há a construção de uma tradição literária feminina negra a partir da escrita de Carolina Maria de Jesus, esta antecedida por outras escritoras negras que lançaram a semente dessa tradição. Argumentamos que, a partir da escrita de Carolina, cria-se uma estética negra feminina que se baseia em quebrar o silenciamento imposto às mulheres pretas no nosso país. Nossa hipótese é que a escrita poderosa de escritoras negras brasileiras se apresenta como força motriz no combate ao racismo.

Introduction. In modern therapy of patients with atrial fibrillation, which belongs to the group particularly at risk of stroke, prophylactic anticoagulation is of primary importance. The initiation and subsequent proper monitoring of long-term anticoagulation therapy is very important for this group of patients. The use of oral anticoagulants significantly reduces the risk of ischemic stroke, and thus ensures longer survival and avoidance of permanent disability among patients with atrial fibrillation. Aim. Assessment of the level of knowledge of patients with atrial fibrillation on thromboprophylaxis in internal departments and cardiology of the Provin-cial Specialist Hospital in Włocławek. Materials and methods. The study group consisted of 100 people (63 men and 37 women) with diagnosed atrial fibrillation, taking oral anticoagulants. The research tool was the author's questionnaire. To assess the risk of ischem-ic stroke in this group of patients, the CHA2DS2-VASc scale was used and ques-tions about these factors were included in the survey. Results. Studies show that anticoagulant prophylaxis in the form of oral anti-coagulants is used in every patient with diagnosed atrial fibrillation. Most pa-tients use new generation drugs (NOAC) that do not require dose adjustment based on a normalized INR. Persistent atrial fibrillation was found in 51% of the patients. The most numerous group were patients in the 65-74 age range. The annual risk of stroke in my subjects was on average 11%. In most cases, patients correctly answered questions about the rules of conduct when using oral anticoagulants, factors that increase and weaken the effects of these drugs and the symptoms of their overdose. There were no significant differences in the level of knowledge between the women and men studied, while younger, better educated patients who declared a very good or satisfactory material situ-ation showed more knowledge. Conclusions. The study showed that the level of patients' knowledge about antithrombotic prophylaxis in atrial fibrillation is at a good level and corresponds to current medical knowledge.
Organ transplantation and chronic disturbances in the health condition of the population – challenges and perspectives
Authors:   University of Health Sciences in Istanbul, Kader Harmanci Seren Arzu
Published: August 2021

End-stage organ failure cases are increasing around the World. Especially chronic kidney failure has been becoming a worldwide epidemic. Although available medical technology and human health resources capacity is enough to transplant organs and tissues to patients diagnosed with end-stage organ fail-ure, many people cannot access the transplantation services because of eco-nomic reasons and organ shortage. Thus, health care professionals should fo-cus on preventing chronic organ failures besides increasing the organ donor pool.

Authors: Ab Rani Nur Izzati , Ismail Syuhaida , Mohamed Zainai , Mat Isa Che Maznah
Published: August 2021

Despite the benefits, globalisation and liberalisation impose challenges to local contractors. Main problem statement: The local contractors’ lack of competitive advantages provides opportunities to their competitors, limiting chances to secure local projects. This study aims to appraise local contractors’ competitiveness with the objective to assess the challenges to compete in the globalisation and liberalisation. Data from the questionnaire surveys on 60 Malaysian international contractors were analysed using the RASCH model. Three challenges assessed are: unstable economic situation, stiff local competition, and building reputation difficulties. The findings are aligned with the 2021-2025 Strategic Plan to encourage local contractors to venture overseas.

Incidence and severity of major diseases of coffee in highland of eastern Ethiopia
Authors: Adem Abdi , Amin Mohammedsani
Published: August 2021

This study was conducted with the objective to assess the incidence and severity of coffee berry disease (CBD) and coffee leaf rust (CLR) in the highland of Eastern Ethiopia. In the east Hararge Zone of Eastern Ethiopia, coffee was grown by 331,651 holders on 7,584 ha with a production output of 3,722 tons and a yield of 0.5 ton/ha in 2017. Bedeno is the leading coffee producer district in the Zone followed by Melka-ballo, Deder and Meta districts. In Bedeno, coffee is mainly grown in altitudes ranging from 1690 to 2260 masl. Coffeeberry disease and leaf rust are the two major diseases of coffee in the area. A total of 34 representative coffee farms at nine study sites (3-4 coffee farms at the interval of 3-5 kilometers) were selected through discussion with Bedeno district’s coffee experts. The study sites were selected using sequential sampling techniques through discussions with the district’s coffee experts. Incidence of coffee berry disease and leaf rust was determined as percentage of diseased trees. Disease severity was determined as percentage of diseased coffee berries per plot. Data were analyzed using descriptive statistics. The result of this study revealed the incidence of CBD in Bedeno district ranged from 30.0 to 93.3% with a mean of 70.19%. The severity of the CBD was from 13.3% to 44.4% with an average severity of 28.53%. Both incidence and severity of CBD were high at Barkalle followed by Barakat and Hindhessa areas. On the other hand, the incidence of coffee leaf rust varied from 18.9 to 87.4% with a mean of 52.7%. The high mean incidence of CLR at highland areas of eastern Ethiopia is clear evidence for the occurrence of climate change in the area. Hence, it is advisable to introduce improved coffee varieties that are resistant to coffee berry disease and leaf rust for production in the area. Training farmers to implement proper cultural disease management practices such as prunning and sucker management will also help alleviate the constraint.

We demonstrate the experimental study of the axial intensity distribution of a quasi-Bessel beam with a droplet structure of the central core, formed by an axicon with the round-tip, and the results of the theoretical calculations. We show that the period of ‘droplet’ quasi-Bessel beam is determined by the shape of the surface rounding and the angle at the top of the axicon lens and depends on the distance to it. The analysis of this dependence makes it possible to restore the shape of the round-tip of the axicon without 3D scanning.

Authors: Gielis Karsten , Vanden Abeele Marie-Elena , De Croon Robin , Dierick Paul , Ferreira-Brito Filipa , Van Assche Lies , Verbert Katrien , Tournoy Jos , Vanden Abeele Vero
Published: August 2021

Background

Mild cognitive impairment (MCI), the intermediate cognitive status between normal cognitive decline and pathological decline, is an important clinical construct for signaling possible prodromes of dementia. However, this condition is underdiagnosed. To assist monitoring and screening, digital biomarkers derived from commercial off-the-shelf video games may be of interest. These games maintain player engagement over a longer period of time and support longitudinal measurements of cognitive performance.

Objective

This paper aims to explore how the player actions of Klondike Solitaire relate to cognitive functions and to what extent the digital biomarkers derived from these player actions are indicative of MCI.

Methods

First, 11 experts in the domain of cognitive impairments were asked to correlate 21 player actions to 11 cognitive functions. Expert agreement was verified through intraclass correlation, based on a 2-way, fully crossed design with type consistency. On the basis of these player actions, 23 potential digital biomarkers of performance for Klondike Solitaire were defined. Next, 23 healthy participants and 23 participants living with MCI were asked to play 3 rounds of Klondike Solitaire, which took 17 minutes on average to complete. A generalized linear mixed model analysis was conducted to explore the differences in digital biomarkers between the healthy participants and those living with MCI, while controlling for age, tablet experience, and Klondike Solitaire experience.

Results

All intraclass correlations for player actions and cognitive functions scored higher than 0.75, indicating good to excellent reliability. Furthermore, all player actions had, according to the experts, at least one cognitive function that was on average moderately to strongly correlated to a cognitive function. Of the 23 potential digital biomarkers, 12 (52%) were revealed by the generalized linear mixed model analysis to have sizeable effects and significance levels. The analysis indicates sensitivity of the derived digital biomarkers to MCI.

Conclusions

Commercial off-the-shelf games such as digital card games show potential as a complementary tool for screening and monitoring cognition.

Authors: O'Campo Patricia , Velonis Alisa , Buhariwala Pearl , Kamalanathan Janisha , Hassan Maha Awaiz , Metheny Nicholas
Published: August 2021

Background

The popularity of mobile health (mHealth) technology has resulted in the development of numerous apps for almost every condition and disease management. mHealth and eHealth solutions for increasing awareness about, and safety around, intimate partner violence are no exception. These apps allow women to control access to these resources and provide unlimited, and with the right design features, safe access when these resources are needed. Few apps, however, have been designed in close collaboration with intended users to ensure relevance and effectiveness.

Objective

The objective of this paper is to discuss the design of a suite of evidence-based mHealth and eHealth apps to facilitate early identification of unsafe relationship behaviors and tailored safety planning to reduce harm from violence including the methods by which we collaborated with and sought input from a population of intended users.

Methods

A user-centered approach with aspects of human-centered design was followed to design a suite of 3 app-based safety planning interventions.

Results

This review of the design suite of app-based interventions revealed challenges faced and lessons learned that may inform future efforts to design evidence-based mHealth and eHealth interventions.

Conclusions

Following a user-centered approach can be helpful in designing mHealth and eHealth interventions for marginalized and vulnerable populations, and led to novel insights that improved the design of our interventions.
Patterns for Patient Engagement with the Hypertension Management and Effects of Electronic Health Care Provider Follow-up on These Patterns: Cluster Analysis
Authors: Wu Dan , An Jiye , Yu Ping , Lin Hui , Ma Li , Duan Huilong , Deng Ning
Published: August 2021

Background

Hypertension is a long-term medical condition. Electronic and mobile health care services can help patients to self-manage this condition. However, not all management is effective, possibly due to different levels of patient engagement (PE) with health care services. Health care provider follow-up is an intervention to promote PE and blood pressure (BP) control.

Objective

This study aimed to discover and characterize patterns of PE with a hypertension self-management app, investigate the effects of health care provider follow-up on PE, and identify the follow-up effects on BP in each PE pattern.

Methods

PE was represented as the number of days that a patient recorded self-measured BP per week. The study period was the first 4 weeks for a patient to engage in the hypertension management service. K-means algorithm was used to group patients by PE. There was compliance follow-up, regular follow-up, and abnormal follow-up in management. The follow-up effect was calculated by the change in PE (CPE) and the change in systolic blood pressure (CSBP, SBP) before and after each follow-up. Chi-square tests and z scores were used to ascertain the distribution of gender, age, education level, SBP, and the number of follow-ups in each cluster. The follow-up effect was identified by analysis of variances. Once a significant effect was detected, Bonferroni multiple comparisons were further conducted to identify the difference between 2 clusters.

Results

Patients were grouped into 4 clusters according to PE: (1) PE started low and dropped even lower (PELL), (2) PE started high and remained high (PEHH), (3) PE started high and dropped to low (PEHL), and (4) PE started low and rose to high (PELH). Significantly more patients over 60 years old were found in the PEHH cluster (P≤.05). Abnormal follow-up was significantly less frequent (P≤.05) in the PELL cluster. Compliance follow-up and regular follow-up can improve PE. In the clusters of PEHH and PELH, the improvement in PE in the first 3 weeks and the decrease in SBP in all 4 weeks were significant after follow-up. The SBP of the clusters of PELL and PELH decreased more (–6.1 mmHg and –8.4 mmHg) after follow-up in the first week.

Conclusions

Four distinct PE patterns were identified for patients engaging in the hypertension self-management app. Patients aged over 60 years had higher PE in terms of recording self-measured BP using the app. Once SBP reduced, patients with low PE tended to stop using the app, and a continued decline in PE occurred simultaneously with the increase in SBP. The duration and depth of the effect of health care provider follow-up were more significant in patients with high or increased engagement after follow-up.

Published: August 2021

Background

Cardiovascular diseases (CVDs) pose a significant health threat and reduce both people’s life expectancy and quality of life. Healthy living is a key component in the effective prevention and treatment of CVD. However, health care professionals (HCPs) experience difficulties in supporting lifestyle changes among their patients. eHealth can provide a solution to these barriers.

Objective

This study aims to provide insights into the factors HCPs find important in the support of patients with CVD in the uptake of and adherence to a healthy lifestyle and the perceived facilitators of and barriers to using eHealth to provide lifestyle support to patients with CVD.

Methods

In-depth interviews were conducted with 16 Dutch HCPs specializing in lifestyle support in cardiac care.

Results

We identified 13 themes, of which the first 12 concerned lifestyle support in general and were related to intervention, patient, or health care. Throughout these themes, the use of eHealth reoccurred as a potential facilitator of or solution to barriers to lifestyle support. Our final theme specifically concerned barriers to the adoption and usability of eHealth.

Conclusions

HCPs do recognize the potential advantages of eHealth while experiencing barriers to using digital tools. Incorporating their needs and values in the development of lifestyle support programs, especially eHealth, could increase their use and lead to a more widespread adoption of eHealth into health care.

Background

The COVID-19 pandemic has resulted in a high degree of psychological distress among health care workers (HCWs). There is a need to characterize which HCWs are at an increased risk of developing psychological effects from the pandemic. Given the differences in the response of individuals to stress, an analysis of both the perceived and physiological consequences of stressors can provide a comprehensive evaluation of its impact.

Objective

This study aimed to determine characteristics associated with longitudinal perceived stress in HCWs and to assess whether changes in heart rate variability (HRV), a marker of autonomic nervous system function, are associated with features protective against longitudinal stress.

Methods

HCWs across 7 hospitals in New York City, NY, were prospectively followed in an ongoing observational digital study using the custom Warrior Watch Study app. Participants wore an Apple Watch for the duration of the study to measure HRV throughout the follow-up period. Surveys measuring perceived stress, resilience, emotional support, quality of life, and optimism were collected at baseline and longitudinally.

Results

A total of 361 participants (mean age 36.8, SD 10.1 years; female: n=246, 69.3%) were enrolled. Multivariate analysis found New York City’s COVID-19 case count to be associated with increased longitudinal stress (P=.008). Baseline emotional support, quality of life, and resilience were associated with decreased longitudinal stress (P<.001). A significant reduction in stress during the 4-week period after COVID-19 diagnosis was observed in the highest tertial of emotional support (P=.03) and resilience (P=.006). Participants in the highest tertial of baseline emotional support and resilience had a significantly different circadian pattern of longitudinally collected HRV compared to subjects in the low or medium tertial.

Conclusions

High resilience, emotional support, and quality of life place HCWs at reduced risk of longitudinal perceived stress and have a distinct physiological stress profile. Our findings support the use of these characteristics to identify HCWs at risk of the psychological and physiological stress effects of the pandemic.
Doctoral Students' Educational Needs in Research Data Management: Perceived Importance and Current Competencies
Authors: Rantasaari Jukka
Published: August 2021

Sound research data management (RDM) competencies are elementary tools used by researchers to ensure integrated, reliable, and re-usable data, and to produce high quality research results. In this study, 35 doctoral students and faculty members were asked to self-rate or rate doctoral studentsâ€™ current RDM competencies and rate the importance of these competencies. Structured interviews were conducted, using close-ended and open-ended questions, covering research data lifecycle phases such as collection, storing, organization, documentation, processing, analysis, preservation, and data sharing. The quantitative analysis of the respondentsâ€™ answers indicated a wide gap between doctoral studentsâ€™ rated/self-rated current competencies and the rated importance of these competencies. In conclusion, two major educational needs were identified in the qualitative analysis of the interviews: to improve and standardize data management planning, including awareness of the intellectual property and agreements issues affecting data processing and sharing; and to improve and standardize data documenting and describing, not only for the researcher themself but especially for data preservation, sharing, and re-using. Hence the study informs the development of RDM education for doctoral students.

Authors: Górecka Aleksandra , Perłowska Anna
Published: August 2021

W artykule podjęto problematykę jakości usług transportu zbiorowego w Warszawie. Na początku rozważań przedstawiono wybrane, dotychczasowe wyniki badań autorów publikowane w literaturze naukowej i branżowej. Wykorzystanie metody luki jakościowej pozwoliło na zweryfikowanie hipotezy badawczej oraz wskazanie wad transportu zbiorowego w mieście. Wyniki potwierdziły trendy przedstawiane w krajowych i zagranicznych publikacjach. Punktualność, częstotliwość kursowania i cena za przejazd, to zdaniem warszawskich pasażerów najważniejsze cechy transportu zbiorowego. W przypadku ceny występowała największa luka jakościowa w odniesieniu do każdego środka transportu. Ogólna ocena wskazała natomiast, że oczekiwana jakość w stosunku do otrzymywanej jest najniższa w przypadku transportu kolejowego.

Lithium carbonate sedimentation using flocculants with different ionic bases
Authors: Morales Yam , Herrera Nelson , Pérez Kevin
Published: August 2021

Lithium has become a metal of enormous interest worldwide. The extensive use of recharge-able batteries for a range of applications has pushed for rapid growth in demand for lithium carbonate. This compound is produced by crystallization, by reaction with lithium chloride (in solution) and by adding sodium carbonate. Low sedimentation rates in the evaporation pools present a problem in the crystallization process. For this reason, in this work, mineral sedimen-tation tests were carried out with the use of two flocculant types with different ionic charges. The tests were carried out at a laboratory level using different dosages for each flocculant and measurements were performed to obtain the increase in the content of solids in the sediment. The anionic flocculant had better performance as compared to that of the cationic flocculant, increasing the sedimentation rate of lithium carbonate by up to 6.5. However, similar solids contents were obtained with the use of the cationic flocculant at 3.5 times lower dosage making it the flocculant of choice regarding the economic point of view.
Endocannabinoid System: Overview and Therapeutic Relevance
Authors: Tagne Alex Mabou
Published: August 2021

The endocannabinoid system (ECS) modulates a variety of physiological processes, attracting considerable attention as a potential target for therapeutic intervention. This complex system is activated by the lipid-derived mediators anandamide and 2-arachidonoyl-sn-glycerol (2-AG), which mainly engage the cannabinoid receptor subtypes 1 (CB1) and 2 (CB2). The biological actions of anandamide and 2-AG are terminated by internalization and intracellular enzymatic hydrolysis catalyzed primarily by the serine hydrolases fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MGL), respectively. Here, we provide an overview of ECS and discuss the implications for advancing pharmacological tools that interfere with such a system as next-generation therapeutics.

Stem cell–derived β-like cells (sBC) carry the promise of providing an abundant source of insulin-producing cells for use in cell replacement therapy for patients with diabetes, potentially allowing widespread implementation of a practical cure. To achieve their clinical promise, sBC need to function comparably with mature adult β-cells, but as yet they display varying degrees of maturity. Indeed, detailed knowledge of the events resulting in human β-cell maturation remains obscure. Here we show that sBC spontaneously self-enrich into discreet islet-like cap structures within in vitro cultures, independent of exogenous maturation conditions. Multiple complementary assays demonstrate that this process is accompanied by functional maturation of the self-enriched sBC (seBC); however, the seBC still contain distinct subpopulations displaying different maturation levels. Interestingly, the surface protein ENTPD3 (also known as nucleoside triphosphate diphosphohydrolase-3 [NDPTase3]) is a specific marker of the most mature seBC population and can be used for mature seBC identification and sorting. Our results illuminate critical aspects of in vitro sBC maturation and provide important insights toward developing functionally mature sBC for diabetes cell replacement therapy.

OBJECTIVE Trends in cardiac risk and death have not been examined in
patients with incident type 2 diabetes and no prior cardiovascular disease.
Therefore, we aimed to examine trends in cardiac risk and death in relation to
use of prophylactic cardiovascular medications in patients with incident
type 2 diabetes without prior cardiovascular disease.

RESEARCH DESIGN AND METHODS In this population-based cohort study, we
included patients with incident type 2 diabetes between 1996 and
2011 through national health registries. Each patient was matched by age and
sex with up to 5 persons without diabetes from the general population. All individuals
were followed for 7 years.

RESULTS We identified 209,311 patients with incident diabetes. From 1996-1999
to 2008-2011, the
7-year risk of myocardial infarction decreased from 6.9% to 2.8% (adjusted hazard ratio [aHR] 0.39, 95% CI 0.37-0.42), cardiac
death from 7.1% to 1.6% (aHR 0.23, 95% CI 0.21-0.24), and all-cause death from
28.9% to 16.8% (aHR 0.68, 95% CI 0.66-0.69). Compared to the general
population, 7-year risk differences decreased from 3.3% to 0.8% for myocardial
infarction, from 2.7% to 0.5% for cardiac death, and from 10.6% to 6.0% for all-cause
death. Use of cardiovascular medications within ±1 year of diabetes
diagnosis, especially
statins (5% users in 1996-1999 vs. 60% in 2008-2011), increased during the
study period.

CONCLUSIONS From 1996 to 2011, Danish patients with incident type 2
diabetes and no prior cardiovascular disease experienced major reductions in
cardiac risk and mortality. The risk reductions coincided with increased use of
prophylactic cardiovascular medications.

The mammalian focal
adhesion proteins Pinch1/2 activate integrins and promote cell-ECM adhesion and
migration; however, their roles in adipose tissue and metabolism are unclear. Here
we find that high fat diet (HFD) feeding dramatically increases expression of
Pinch1/2 proteins in white adipose tissues (WAT)
in mice. Furthermore, expression of
Pinch1 is largely up-regulated in WAT in the Leptin-deficient ob/ob type 2
diabetic mice and obese humans. While mice with the loss of Pinch1 in
adipocytes or global Pinch2 do not display any notable phenotypes, deleting
Pinch1 in adipocytes and Pinch2 globally significantly decreases body weight
and WAT, but not brown adipose
tissue (BAT), mass in HFD-, but not normal chow diet (NCD)-, fed mice. Pinch
loss ameliorates HFD-induced glucose intolerance
and fatty liver. After HFD challenge, Pinch loss slightly, but
significantly, accelerates energy expenditure. While
Pinch loss decreases adipocyte size and alters adipocyte size distribution, it greatly accelerates cell apoptosis primarily in epididymal WAT and to a less extent
subcutaneous WAT. In vitro studies demonstrate that Pinch loss accelerates adipocyte apoptosis by activating the
Bim/Caspase-8 pathway. In
vivo, genetic ablation of Caspase-8 expression in adipocytes essentially abolishes
the ameliorating effects of Pinch deficiency on obesity, glucose intolerance
and fatty liver in mice. Thus, we demonstrate a
previously unknown function of Pinch in control of adipose mass, glucose and
fat metabolism via modulation of adipocyte apoptosis. We may define a novel
target for the prevention and treatment of metabolic diseases, such as obesity
and diabetics.

Published: August 2021

The main result states that each positive polynomial p in N variables with coefficients in a unital Archimedean f-ring K is representable as a sum of squares of rational functions over the complete ring of quotients of K provided that p is positive on the real closure of K. This is proved by means of Boolean valued interpretation of Artin's famous theorem which answers Hilbert's 17th problem affirmatively.
