Effects of pine (Pinus densiflora) sawdust on cordycepin yield from medicinal fungus Cordyceps militaris in submerged culture
Authors: Ha Si Young , Jung Ji Young , Park Jai Hyun , Yu Chan Yeol , Park Jae-Hyeon , Yang Jae-Kyung
Published: November 2021

Cordycepin (3′-deoxyadenosine) is a nucleoside analog that exhibits a broad spectrum of biological activity. The effects of different tree sawdust on cordycepin as bioactive substances for mycelium growth were investigated. Pine sawdust was essential for increasing cordycepin content. Furthermore, a 1% NaOH-pretreated pine sawdust produced the highest cordycepin yield. The cordycepin yield of mycelium in submerged culture was significantly increased when the particle size was 100-mesh and the weight was 20 g/L of 1% NaOH-pretreated pine sawdust, with an increase of up to 38% compared to the control (only sabouraud dextrose broth (SDB)). The results demonstrated the effects of different tree sawdust on the biosynthesis of cordycepin as bioactive substances and that replacing traditional medium (SDB medium) with 1% NaOH-pretreated pine sawdust can increase the yield of cordycepin. After optimization of cordycepin production from Cordyceps militaris cultivated in medium containing 1% NaOH-pretreated pine sawdust using RSM (response surface methodology) BBD (Box-Behnken design) in its canonical form, the optimum combination was: particle size, 113.7-mesh; input weight, 11.9 g/L; and incubation time, 67.8 h. The model predicted a maximum yield of 922.6 μg/mL for cordycepin.

Published: November 2021

The effects of two total solids contents (TS) and two inocula were studied for the semi-continuous high-solids anaerobic digestion (HS-AD) of cassava pulp under mesophilic conditions (35 ± 2 °C). In the 1.0-L bioreactors, two TS of 15% and 20% with digestate as a sole inoculum were chosen to run the HS-AD, and two inocula (the digestate from the AD of cassava pulp and sewage sludge) were used separately under TS 20%. All treatments were carried out at the organic matter loading rates (OLRs) of from 3.0 to 10.0 kg volatile solids (VS)/(m3·d), with each phase of 6 days followed by two 3-days phases of no feeding and then low OLR of 6.5 kg VS/(m3·d). Compared with TS 15%, the bioreactors of TS 20% with the digestate had a higher buffering capability to alleviate the rapid acidification and a higher level of the specific methane yields (SMYs) of from 0.212 to 0.233 m3/(kgVSadded) at the OLRs of 4.0 to 6.5 kgVS/(m3·d), while TS 15% obtained the highest SMY of from 0.152 to 0.182 m3/(kgVSadded) at the OLR of 4.0, 6.5, and 8.0 kgVS/(m3·d). In contrast, sewage sludge did not restrain the rapid acidification and only yielded quite small SMYs under TS 20%.

Published: November 2021

This study aimed to investigate the influence of moisture content variation on 12 mechanical properties of the Cedrelinga catenaeformis species. Of the 12 properties, four were significantly affected (based on analysis of variance at 5% significance level), and the compression and shear strengths in the direction parallel to the fibers exhibited the greatest difference in values from the saturated moisture condition of up to 12% (approximately 34% increase). Toughness exhibited a behavior different from that predicted by the normative equation, in which increase in moisture content implied increase (approximately 59%) of the property studied. Because a good part of the properties was not significantly affected and Brazilian standard ABNT NBR 7190 (1997) considers expressions that lead to a considerable increase in mechanical properties with the reduction of moisture content, this approach was unfavorable to the safety of the project, motivating the development of other studies to collaborate in revisions of this normative document.
H2O2 bleaching of brown pulp with adsorbed xylan and its modifying effects on the mechanical properties of paper
Authors: Zhang Xue , Li Lizi , Tian Junfei , Li Nanhua , Zuo Leigang , Yan Luming , He Jiang , Du Xianyong
Published: November 2021

Xylan is the primary hemicellulose in most hardwood species, especially in birch. Research has highlighted the exploitation of xylans as a strength-enhancing additive to paper due to the current trend for the effective utilization of biomass. In this paper, a new pulping process was proposed, which involved the extraction of xylan prior to pulping, followed by the re-adsorption of the pulp after the final stage in the digester, followed by a suitable bleaching process. The aim of this work was to bleach hardwood kraft pulp (brown pulp) with adsorbed birch xylan via hydrogen peroxide and study the effect of the bleaching parameters on the paper properties. The results showed that the optical properties of paper decreased; however, the mechanical properties increased after the brown pulp adsorbed birch xylan. During the bleaching process, better mechanical properties were obtained with shorter bleaching times and lower bleaching temperatures, initial pHs, and MgSO4 dosages. However, the optical properties were improved as the bleaching time, temperature, initial pH, and MgSO4 dosage were increased. The adsorption of birch xylan could effectively modify the mechanical properties of paper made from brown pulp under various phases.
Carbon footprint accounting and low-carbon path optimization for imported timber-based wooden furniture supply chains
Authors: Wang Hui , Wu Jinzhuo , Chen Zhili
Published: November 2021

Using an imported timber-based solid wood box bed (2000 mm × 1800 mm) as the functional unit, the ILCD 2011 midpoint assessment method was used to measure the life cycle carbon emissions of the product. Using this assessment, the Dijkstra algorithm was adopted to determine the shortest supply chain path and to obtain the minimum carbon footprint of the supply chain. Results showed that the total carbon footprint of the wood bed was 464 kg for the control case. For experimental cases, the carbon footprint ranged from 456 kg to 517 kg CO2-eq. The upstream process was identified as the primary contributor to the carbon footprint, accounting for 74.6% to 80.7% of the total carbon footprint, followed by the downstream and the core-stream processes. Configuration of a timber harvesting system with lower fuel consumption, purchasing timber from areas within shorter transportation distance, and reducing the proportion of incineration for waste treatment were feasible solutions to reduce the carbon footprint of the product. A case study optimizing the low-carbon path for the wooden furniture supply chain determined the shortest path for the participants in each link, such that the minimum total carbon footprint of the supply chain was 463 kg CO2-eq.

Based on the solubility parameter theory, the Hansen solubility parameters of various solvents were calculated and compared to predict the solubility of cellulose in various solvents, which illustrates the feasibility of Hansen solubility parameters to predict the solubility of cellulose in solvents. This paper aims to make a more accurate prediction in advance when finding suitable cellulose solvent system, and then to reduce the burden of cellulose solvent selection.
Effect of uniaxial stress on bursting energy absorption of paper
Authors: Olejnik Konrad , Stanisławska Anna , Bloch Jean-Francis
Published: November 2021

The overall usefulness of the bursting energy absorption (BEA) was studied for a better analysis of paper strength properties. Additionally, the changes of the BEA during more complex deformations of paper products, e.g., preliminary or simultaneous tensile and burst, were determined. For the purpose of the research, an experimental setup was designed. The results showed that the correlation between BEA and bursting strength was linear, but the proportionality strongly depended on paper grade. Thus, a more accurate method to characterize the bursting resistance (BR) of paper was proposed. The BR parameter is described by the three following parameters: average bursting strength, average bursting energy absorption, and the slope of the fitted linear regression curve (relationship between the bursting energy absorption and the bursting strength). This method revealed new mechanical behaviors of papers related to their preloading.
Estimating wooden prefabricated building export potential from the Province of Quebec to the northeastern United States
Authors: Cid Allan , Blanchet Pierre , Robichaud François , Kinuani Nsimba
Published: November 2021

The import activity of wooden prefabricated buildings in the Northeastern US region was over CAD 41.8 million during 2019, according to the US Census Bureau. This amount was growing at a 12.5% annual rate on average since 2017. There is evidence of a continued shortfall in supply for the construction market to be overcome in the region. The objective of this study was to estimate the export potential of wooden prefabricated buildings from the Province of Quebec to the Northeastern US region for the next decade in relation to the export activity and production capacity of the industry. The value of annual production of wooden prefabricated buildings in Quebec was up to CAD 578 million in 2019, according to iCRIQ. Export activities from Quebec are mainly directed to the Northeastern US, and were of CAD 18.8 million in 2019, or 81% of Quebec’s wooden prefabricated building exports. Results suggest that potential for wooden prefabricated building exports from the Province of Quebec to the US Northeastern region is important in terms of market share. The study also suggests that by drastically increasing the production capacity of the industry there is no chance that supply will overcome demand.

Published: November 2021

The present study was performed during two successive seasons 2019 and 2020 to investigate the effect of the soil application of fulvic acid (FA), seaweed extract (SE), and their different combinations on vegetative growth, yield, and fruit quality of six-years-old guava (Psidium guajava L.) cv. ‘Maamoura’. The trees were planted 4 × 4 m2 apart in clay soil under a flood irrigation system. They were treated three times starting from mid-March with one-month intervals with the following treatments: Control (water only), 3 and 4 g/L FA, 3 and 4 g/L SE, and their different combinations; 3 g/L FA + 3 g/L SE, 3 g/L FA + 4 g/L SE, 4 g/L FA + 3 g/L SE, and 4 g/L FA + 4 g/L SE. The results clearly showed that the application of FA or SE solely or in combinations increased shoot length and diameter, as well as leaf chlorophyll compared with the control. The treatments also increased fruit set percentage, fruit yield, and fruit physical and chemical characteristics such as fruit weight, size, TSS%, total reduced and non-reduced sugars, as well as leaf mineral content, while they decreased the fruit acidity compared with the control in the two seasons.
The Story of Stenka Razin and the Persian Princess in Direct and Inverse Projections: Yevgeny Zamyatin and Anna Barkova
Authors: Zuseva-Özkan Veronika
Published: November 2021

The article considers two cases of the creative reception of the legend about Stenka Razin and the Persian princess in Russian literature of the 1920s – in Yevgeny Zamyatin’s tragedy Atilla (1925–1928) and screenplay Stenka Razin (1932–1933), on the one hand, and in the play by A. Barkova Nastasya Kostyor (1923), on the other hand. The direct and inverse projections of Razin’s plot are represented: in Zamyatin’s case the roles of Razin and the princess are distributed in the traditional way, as they are typical for the long history of this plot in Russian culture – both in folklore and in literature, and in Barkova’s case these roles are reversed in the gender aspect. This peculiarity is considered as connected to Barkova’s interest toward “woman question”, the problem of female emancipation, women’s equality. The plot of Stenka Razin and the Persian princess is analyzed in the article together with another one – the plot featuring the woman warrior, since they are closely interrelated in Russian literature of the 1920s. The hypothesis is that this relationship is due to the active demolition of the old gender order during this period.
The Image of Syrian Refugees in the Lebanese Press: Case of Al-Akhbar Newspaper
Authors: El Zein Hatem
Published: November 2021

This paper investigates how Syrian refugees are portrayed in the Lebanese press, namely in Al-Akhbar Newspaper.

Although there are existing studies that focus on the media representation of Syrian refugees, they allot significant attention to negative images of Syrian refugees presented by a number of Lebanese media outlets. In addition, there is a dearth of studies that scrutinise positive representation of Syrian refugees in the Lebanese press.

Owing to these problems, this paper bridges the gap in the current literature through paying further attention to the positive media representation of Syrian refugees in the Lebanese press taking the case of Al-Akhbar Newspaper.

In answering the question: how Al-Akhbar depicts Syrian refugees who fled to Lebanon, this paper analyses samples of articles published in Al-Akhbar to highlight the discourse of this Newspaper relating to Syrian refugees. The paper draws on qualitative analysis to arrive at its conclusion.

The findings of the paper are significant because they reveal journalistic practices and agenda towards one of the serious issues in Lebanon which suffers from political turmoil and severe economic crisis. As this paper distinguishes between what it calls antagonist and protagonist discourses in reporting Syrian refugees in the Lebanese press, it recommends paying further attention to the protagonist discourse because it reflects good journalistic practice.
„Atgimimo banga“ Challenge to Soviet Mass media: Reform Movement of Lithuania (Sąjūdis) Telecast as „Open Protest Field“ in Time of Political Changes (1988 June– 1990 March)
Authors: Vaitelė Tomas
Published: November 2021

During the Soviet occupation, the whole Lithuanian SSR media was regarded as one of the key propaganda tools based on pure ideological content and socialist-communist messages. In such a media setting television played an essential role; together with radio (as in Moscow’s example) the latter felt under control of a committee ruled by the Council of Ministers (CM), Central Committee (CC) and Moscow patrons itself. But this situation was about to change when Sąjūdis (Reform Movement of Lithuania) came to public and tried to established its right to uncensored broadcast time via television for its own dissemination of information, which sometimes had a strong political message and was not in favour of ruling regime and party. Sąjūdis had a purpose which was totally new during Lithuanian SSR times since the start of television broadcasts in 1957 – it was uncensored broadcasting time. Based on archive sources, memoirs and press articles, this research focuses on the telecast “Atgimimo banga“ as one of the essential informational channels for Sąjūdis. This article tries to disclose its history, influence and conflicts between Sąjūdis and ruling regime, which tried to control and censor telecast’s content. Eventually, the sporadic telecast’s format had another effect: when in 1989 Sąjūdis became important part of the Lithuanian SSR political system, telecast’s popularity came to decline. One of the most popular perestroika time TV programs had some unfulfilled expectations, and, during the time, it made it as one of the most unpopular. The chronological boundaries of this research start at June of 1988, when Sąjūdis was created, and ends in March of 1990, when Lithuania declared its independence from Soviet Union.

Published: November 2021

OBJECTIVES

At the onset of the coronavirus disease 2019 pandemic, disruptions to pediatric care and training were immediate and significant. We sought to understand the impact of the pandemic on residency training from the perspective of pediatric residents.

METHODS

We conducted a cross-sectional survey of categorical pediatric residents at US training programs at the end of the 2019–2020 academic year. This voluntary survey included questions that explored the impact of the coronavirus disease 2019 pandemic on resident training experiences, postresidency employment plans, and attitudes and perceptions. Data were analyzed by using descriptive statistics and mixed-effects regression models. We performed a sensitivity analysis using respondents from programs with a >40% response rate for questions regarding resident attitudes and perceptions.

RESULTS

Residents from 127 of 201 training programs (63.2%) completed the survey, with a response rate of 18.9% (1141 of 6032). Respondents reported multiple changes to their training experience including rotation schedule adjustments, clinic cancellations, and an increase in the use of telemedicine. Respondents also reported inconsistent access to personal protective equipment and increased involvement in the care of adult patients. Graduating resident respondents reported concerns related to employment. Respondents also noted a negative impact on their personal wellness.

CONCLUSIONS

Responding residents reported that nearly every aspect of their training was impacted by the pandemic. Describing their experiences may help residency program and hospital leaders supplement missed educational experiences, better support residents through the remaining months of the pandemic, and better prepare for extraordinary circumstances in the future.
Follow-Up Blood Cultures in Young Infants With Bacteremic Urinary Tract Infections
Authors: Franz-O’Neal Erika , Olson Jared , Thorell Emily A. , Cipriano Frank A.
Published: November 2021

BACKGROUND AND OBJECTIVES

Researchers in previous studies suggest that the clinical yield of follow-up blood cultures (FUBCs) is low in infants with bacteremic urinary tract infection (UTI) because persistent bacteremia is rare; however, no researchers have analyzed the practice of routinely obtaining FUBCs. In our study, we evaluate outcomes in infants with FUBCs, examine opportunities for improvement of blood culture practices, and add important information to inform both clinical practice as well as further study.

DESIGN

This retrospective cohort study included infants <90 days of age with bacteremia and UTI with the same pathogen at 22 hospitals that make up Intermountain Healthcare between 2002 to 2020. Infants with culture proven meningitis, osteomyelitis, central line infection, and infections occurring during NICU hospitalization were excluded.

RESULTS

Total number of patients with bacteremic UTI was 174, 153 (88%) patients had at least 1 FUBC, 14 of 153 (9%) had a positive FUBC with same organism, and 4 of 153 (3%) were contaminants. The length of stay was longer for patients with positive FUBCs. Patients with Escherichia coli are more likely to have a negative FUBC. Readmissions within 30 days were similar among infants with positive FUBCs, negative FUBCs, and no FUBCs.

CONCLUSIONS

FUBCs in infants with bacteremic UTI should not be routinely performed, especially for E coli, and it is unclear whether FUBCs improve outcomes.

Published: November 2021

OBJECTIVES

Coronavirus disease 2019 (COVID-19) has had a significant impact on adult residents and staff in long-term care facilities. Little is known, however, about the impact of COVID-19 and the uptake of COVID-19 vaccination in pediatric long-term care facilities (pLTCFs).

METHODS

A survey was designed, piloted, and e-mailed to facilities participating in the Pediatric Complex Care Association, an organization consisting of 43 pLTCFs. Respondents were sent 1 reminder and given 1 month (April 2021) to report retrospective data from March 2020 to March 2021. In the survey, pLTCFs were asked to report data on COVID-19 infections and outcomes among residents and staff as well as COVID-19 vaccination status among residents and staff.

RESULTS

Twenty-five centers participated, representing a 56% survey response rate. Of the residents, 7.0% (117 cases) were infected with COVID-19. The proportion of residents with COVID-19 by site varied from 0% to 41%. Among staff members, 22% (1665 cases) were infected with COVID-19, with a range of 8% to 44% of staff by site. Of residents, 1.3% were transferred to acute care. There were 3 resident deaths and 4 staff deaths. Early uptake of COVID-19 vaccination was common for residents (76%), whereas for staff, the rate was lower at 62%. At individual pLTCFs, vaccination ranged from 5 to 83 residents and 46 to 499 staff.

CONCLUSIONS

Pediatric residents and staff of long-term care facilities were impacted by COVID-19, but mortality was low. COVID-19 vaccination rates among the children and staff were similar and higher than that reported from early national data in skilled nursing facilities.

The aim of the present study is to establish the extent to which natural resources are used and how traditional livelihood practices are exercised at a regional level. The object of this study is a region with developed mass tourism - Bansko Municipality. The subject addresses traditional livelihood practices and opportunities for expanding alternative forms of tourism.
The revival of traditional livelihood models, which directly corresponds to current trends in bioeconomy, can make alternative forms of tourism an important part of the local development strategies in the forthcoming programming period after 2020, including regions established as mass tourism ones. The study has been conducted by applying the survey method in the municipality of Bansko in the period of February-March 2020 coinciding with the onset of the epidemic situation related to COVID-19 in Bulgaria. Taking into account the results from the survey, it is possible to draw conclusions about the extent to which certain conditions for the development of alternative forms of tourism have been created when facing new challenges.
TRENDS IN THE REGIONAL DEVELOPMENT OF BULGARIA
Authors: Petrov K.
Published: November 2021

The report examines the socio-economic condition of the Republic of Bulgaria. Some sectors of the Bulgarian economy have been analysed, taking into account their regional peculiarities and revealed serious structural weaknesses. The problem of the effectiveness of the country's financial management was also highlighted, reflecting the dependence on the country's external financing. Another major drawback in the economic development of the country is the state of the transport infrastructure and the maximum utilization of its potential, which inevitably affects the regional integration and local socio-economic development. The report shows the evolution of understandings for rural regions in Bulgaria. They are unified by the area in which they develop – rural regions. They offer opportunities for rest and recovering in environment which is absolutely opposite to the one in their urban and industrial area. In this scope are examined the economic structure of regional development and rural areas in these territories, territorial differences (variety) in the change of employment and unemployment, the role of the demographic situation as a factor in the sustainable development.

Purpose of the research is to formulate proposals for improving the local financial system by strengthening/enhancing the relationship between local revenues and expenditures and the economic development of the municipality. The study uses large data sets for economic development at municipal level, financial data for municipal budgets and comparative data on local finances in the European countries. The Results show the stronger connection between local revenues and expenditures and the economic development of the municipality is, the more local problems will be solved at a local level, whereas the population will be aware of the cost of local services, and local government will depend on its taxpayers, will be guided and controlled by them, i.e. business and living conditions for the local population will be improved. Мain inferences from the analysis are drawn and recommendations for changes in the local financial system are justified.
JIHAD BUKAN HANYA PERANG SUCI: Telaahan Teoritik Terhadap Ayat-Ayat Jihad dalam Al-Quran
Authors: Sefriyono Sefriyono
Published: November 2021

Of the 114 surahs in the Qur'an, there are 24 surahs with 164 verses that talk about jihad in various variations of words. Of the 164 verses, there are 22 verses that have the potential for acts of violence if understood literally and coupled with the dominance of qital words in these verses. The qital verses are said to have been revealed more in the Medina period, when compared to the Mecca period, which talked a lot about self-control. The dynamics of the Muslims at that time also contributed to the change in the terminology of jihad. Jihad is not only defined by war or acts of violence. The invitation of parents to polytheism, for example, as contained in chapter 29 paragraph 8 and letter 31 paragraph 15 does not have to be fought with violence. This verse even continues to recommend to continue to do good to the parents in question. In other Surahs such as Sura 45 verse 15 there is also a recommendation with wealth, not carrying weapons. This has given rise to various forms of meaning about jihad, such as greater jihad (al-jihad al-akbar)—the struggle against self and lesser jihad (al-jihad al-asghar)—fighting those who are hostile to the way of Allah. On the one hand, jihad can also be interpreted in an esoteric way—mujahadah, namely a genuine effort to draw closer to Allah, on the other hand, it can also be interpreted exoteric—the holy war.

Published: November 2021

ABSTRACT Background: Multiple sclerosis progression and disability can be rated differently by healthcare professionals. Therefore, how physicians perceive the disease can impact treatment decisions. There are no previous studies on this matter. Objective: To translate and transculturally validate the Revised Illness Perception Questionnaire for Healthcare Professionals (IPQ-R HP), for use in Brazilian Portuguese. Methods: The process used to validate the IPQ-R HP was based on the steps presented in the guide proposed by Dorcas Beaton. The final version of the IPQ-R HP had 38 questions, divided into seven different dimensions to assess the patient's disease. Also, two clinical cases that were representative of real-life patients with multiple sclerosis (MS) were assembled to consider the two main profiles of the disease. We applied the questionnaire to neurologists at the Federal University of São Paulo (UNIFESP) to assess their perception of MS. These doctors also answered a brief survey to establish the profile of the interviewees. For statistical analysis, we used Bayesian CFA models and kappa statistics. Conclusions: The kappa statistics showed a general agreement of 0.4. For the Bayesian CFAs with seven-factor correlation solution, we had a poor fit for case 1 with a 95% confidence interval ranging from -52.893 to 273.797 and a PPP of 0.107. Regarding case 2, the model did not converge even after 50,000 iterations, which indicated that the specified model (i.e. seven-factor correlation solution) for case 2 was inadmissible. Thus, the IPQ-R HP questionnaire in Brazilian Portuguese has not been validated.
Association between headache and tinnitus among medical students

Published: November 2021

ABSTRACT Background: Headache is a very common complaint and it is increasingly prevalent among university students. Tinnitus consists of subjectively perceived sounds that occur in the absence of an external auditory signal. Presence of headache and tinnitus in association has implications for therapy and prognosis, because this describes the temporality of the symptoms. Recognition of the epidemiological profile of symptomatic students might contribute to interventions. Objective: To investigate the prevalence of the association between headache and tinnitus, and to describe the epidemiological profile of the study population and the chronological order of appearance of these symptoms. Methods: Cross-sectional, observational and analytical study on a sample representative of an academic center. Data referring to the epidemiological and clinical profile of headache and tinnitus among medical students were collected through an online questionnaire built using the Google Forms tool. Results: Out of the 234 participants, 26.1% reported having tinnitus and headache (p < 0.001). The participants with headache were more likely to be women (p = 0.045), white (p = 0.009) and 21-25 years old (p = 0.356). Among right-sided, left-sided and non-unilateral headaches, tinnitus was present predominantly in the non-unilateral type, but without statistical significance. Regarding timing, 18.0% of the students said that tinnitus started before headache, 57.4% said that headache started before tinnitus and 24.6% said that they started simultaneously. Conclusions: An important association between headache and tinnitus regarding lateralization and temporality was demonstrated. Thus, these data match the presumption that headache and tinnitus have a physiopathological connection.

ABSTRACT Objective: to describe the implications of the diagnosis and treatment of non-inflammatory pancreatic cysts in a series of patients. Methods: we included patients with pancreatic cysts ≥1.0 cm, excluding those with a presumptive diagnosis of a pseudocyst. Imaging tests, echoendoscopy, and histopathology determined the diagnosis of the type of cyst. We applied the guidelines of the International Association of Pancreatology, with some modifications, in patients with mucinous or indeterminate lesions. Results: 97 adult patients participated in the study. A cystic neoplasm of the pancreas was diagnosed in 82.5% of cases. Diagnosis was mainly made by magnetic resonance (46% of cases). The two most common diagnoses were intraductal papillary mucinous neoplasm (43.3%) and serous cystadenoma (26%). Twenty-nine patients underwent surgery (33.3%). The most common surgical procedure was distal pancreatectomy associated with splenectomy in 19 cases (65.5%). Among the operated patients, 11 were diagnosed with cancer. None of the followed, non-operated patients had a diagnosis of cancer. Conclusions: magnetic resonance showed good accuracy, particularly in the diagnosis of intraductal papillary mucinous neoplasm. The guidelines of the International Association of Pancreatology, as applied in this study, showed a negative predictive value for cancer of 100%. A development of better diagnostic tests can reduce the number of unnecessary operations.

ABSTRACT Introduction: obstructive Sleep Apnea Syndrome (OSAS) is a serious confition that compromises the quality of life and survival of patients. Its main risk fator in adults is obesity and the gold standard test for diagnosis is polysomnography (PSG), mainly through the apneia-hypopnea index (AHI). Objective: to analyze the sleep pattern of obese patients with indication for bariatric surgery, determining the main polisomnographic parameters compromised by obesity. Methods: This work is a cross-sectional study with analysis of polysomnography perfomed in patients with obesity in the peroperative period of bariatric surgery at a clinic in Vitória da Conquista/BA during 2017. The Epi Info 7 platform was used for analysis of the data. Results: 58 polysomnographic reports were analyzed, with 56,9% morbdly obese and 43,1% non-morbid. The prevalence of OSAS was 70,68% and de AHI ranged from zero to 84,6 with a mean of 19,47±22,89 e/h. morbidly obese, compared to “non-morbid”, had a longer saturation time below 80% and 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectively; p-value=0,02 in both), worse index respiratory disorders ((29,24±25,36 vs. 16,88±16,21; p-value=0,02), higher AHI (24,71±25,68 vs. 12,56±16,67; p-value=0,02), higher hypopnea index values (16,41±17,10 vs. 6,99±8,52; p-value=0,006) and lower minimum saturation (78,24±9,80 vs. 85,24±6,33; p-value=0,004). Conclusions: the high prevalence of OSAS found confirms its indication in the preoperative period of bariatric surgery. The main respiratory event involved in most individuals with OSAS was the hypopnea index.

Em 2015, houve um aumento de casos de más-formações congênitas entre recém-nascidos no Brasil associado ao vírus Zika, com repercussões sociais e econômicas para as famílias. O objetivo deste estudo foi estimar a prevalência de gasto catastrófico para famílias de crianças com síndrome congênita do vírus Zika (SCZ) grave, leve/moderada em comparação com famílias de crianças sem diagnóstico de SCZ, no Estado do Rio de Janeiro. O termo gasto catastrófico ocorre quando o gasto excede determinada proporção da renda da família devido à doença. Os cuidadores de crianças com SCZ grave eram mais jovens, com menor escolaridade e renda. A prevalência de gasto catastrófico foi maior em famílias de crianças com SCZ. Dentre os cuidadores de crianças com SCZ grave, identificou-se que a prevalência de gasto catastrófico foi mais elevada entre aqueles que apresentaram graus de depressão, ansiedade e estresse graves ou muito graves. O baixo apoio social entre os cuidadores também foi determinante para o aumento da prevalência do gasto. A carga que incide sobre os cuidadores de crianças com SCZ grave potencializa uma situação de vulnerabilidade que demanda a amplificação do acesso aos mecanismos de proteção financeira e social, através da articulação de diferentes políticas que sejam capazes de alcançar efetivamente esse grupo.

O presente estudo avaliou o efeito de determinantes contextuais e individuais da utilização da triagem auditiva neonatal no Distrito Federal e capitais brasileiras. O modelo teórico conceitual proposto por Andersen & Davidson (2014) orientou as análises mediante modelagem logística multinível, com dados da Pesquisa Nacional de Saúde, 2013. A população observada (n = 585) é representativa de 230.112 duplas de mulheres/responsáveis acima de 18 anos e respectivas crianças menores de 2 anos de idade. No nível contextual (Distrito Federal e capitais), a utilização da triagem auditiva neonatal foi determinada pela proporção de indivíduos extremamente pobres (razão de chances - RC = 0,91; intervalo de 95% de confiança - IC95%: 0,83-0,99) e pela cobertura mensal da triagem auditiva neonatal (RC = 1,02; IC95%: 1,01-1,02). No nível individual, verificou-se maior uso de triagem auditiva neonatal na faixa etária entre 25 e 39 anos, em comparação às < 25 anos. A chance de utilização de triagem auditiva neonatal foi menor em respondentes com raça/cor da pele parda (RC = 0,47; IC95%: 0,26-0,83) em comparação com brancas. Quanto à escolaridade, verificou-se que possuir Ensino Superior completo quase triplicou a chance de uso de triagem auditiva neonatal, em contraste com Ensino Fundamental de estudo formal (RC = 2,99; IC95%: 1,15-7,79). O pré-natal predominantemente privado aumentou em 2,18 vezes a chance de utilizar a triagem auditiva neonatal , em comparação ao público (RC = 2,18; IC95%: 1,02-4,64). A aplicação efetiva de leis e políticas de saúde auditiva já existentes e a priorização de práticas de atenção básica e educação em saúde com foco em neonatos em maior vulnerabilidade, conforme as características identificadas nesse estudo, são iniciativas para ensejar um sistema de proteção social equânime.

RESUMO A partir de referenciais do feminismo negro, da perspectiva interseccional e dos estudos étnicoraciais no Brasil, problematizam-se o racismo e o sexismo na academia brasileira com base na caracterização e análise da presença/ausência de professoras negras em programas de pós-graduação em ciências da saúde de duas universidades federais fluminenses, UFRJ e UFF. Utilizando informações de sites de 31 Programas de Pós-Graduação (PPG), reconstruíram-se quantitativamente os perfis de gênero e étnico-raciais por universidade e área de avaliação. Identificaram-se 23 professoras negras que ocupam 26 vagas docentes nos PPG analisados. Com base em informações da Plataforma Lattes, também se abordou longitudinalmente a dimensão de estudo. Os resultados assinalam que a presença de professoras negras é de 2% na UFRJ e de 6% na UFF; que ela é maior em áreas relativas aos cuidados e ínfima em áreas de maior prestígio científico e socioeconômico, como medicina. Constata-se o racismo como principal sistema de poder, operando no contexto institucional e disciplinar. Neste último, associado ao sexismo que determina as hierarquias de gênero nas áreas de saúde. Observa-se, também, que as desigualdades de raça se sobrepõem às de gênero no contexto desta pesquisa, confirmando as teses que apontam o epistemicídio dos saberes negros.
Da violência epistemológica a epistemologias próprias: experiências de narrativas com mulheres cis periféricas, mulheres trans e travestis

RESUMO Este artigo apresenta compreensão de problemáticas enfrentadas por mulheres cis periféricas, mulheres trans e travestis na construção de epistemologias próprias no campo das ciências. Para tal, baseia-se no campo construído por três teses de doutorado, cujos autores são os mesmos deste artigo. As teses, embora não tenham como foco principal e central o mesmo do presente artigo, evidenciam, a partir do campo construído, que pouco conhecimento a respeito das populações trans, travesti e periférica é produzido por seus integrantes. Identifica-se, a partir da releitura do material produzido pelos pesquisadores, a existência de trincheiras, que se interpõem no caminho percorrido por mulheres trans, travestis e mulheres cis periféricas para produzir conhecimento. São elas: a própria sobrevivência, a permanência no ensino e a validação do conhecimento produzido por corpos e existências não hegemônicas. Discute-se, por fim, que há um descompasso entre as políticas de educação vigentes e as experiências vividas, indicando uma fissura em práticas de saúde e no cuidado integral dessa população. A isso, somam-se violências e iniquidades em saúde que acabam interferindo na comunicação e na potência do saber popular como estratégia de resistência e saber científico, contrapondo-se ao saber acadêmico hegemônico.
Viralizando Lygia Clark: sopros para contagiar de encanto a experiência do cuidado

Published: November 2021

RESUMO Esta escrita é desdobramento de um percurso investigativo comum das autoras a partir da obra da artista brasileira Lygia Clark, especialmente no que tange às interfaces arte-vida, arte-clínica, arte-política, implicadas em suas obras e proposições. Temos a psicologia e a dança como territórios profissionais-existenciais de partida e nos interessamos pelas experiências tecidas em uma trama transdisciplinar. No ano de centenário da artista, 2020, acordamos a memória inscrita no corpo da trajetória de Lygia Clark nos indagando sobre as possíveis contribuições de seu legado na contemporaneidade. Compreendemos que a violência colonial, que insiste nos tempos de agora, incide sobre o corpo, anestesiando sua dimensão sensível e absorvendo sua dimensão criadora, e se estabelece por meio de uma política de desencantamento da vida. O movimento de produção de saúde, que a trajetória de Lygia inspira, faz-nos afirmar seu percurso como possibilidade de ativação da dimensão sensível do corpo e de restauração do sentido de encanto. Por meio da partilha de algumas memórias de experimentações que foram criadas no contágio com a sua obra, desejamos criar sopros que liberem sentidos à aventura do viver e teçam espaços de ativação de uma saúde poética.

RESUMO O risco iminente de desabastecimento de ventiladores pulmonares nos serviços de saúde acarretou diversas frentes de trabalho para disponibilizar o maior número possível desses equipamentos para o tratamento dos pacientes acometidos. O agravamento da crise sanitária colapsou serviços de saúde com busca isocrônica por leitos. Em meio ao colapso, foi detectada nova variante da linhagem Sars-CoV-2 e confirmado o primeiro caso de reinfecção. Entre os pontos críticos, foi destaque a escassez caótica de oxigênio e taxas de ocupação de leitos acima de 90%. Pretende-se relatar a participação das autoras nas iniciativas para o enfrentamento da pandemia de relevância internacional. Destacar a participação de mulheres em atividades que são cruciais para responder, em tempo oportuno, às demandas oriundas de emergências sanitárias. Por meio de método de pesquisa de abordagem descritiva e exploratória, buscou-se verificar o perfil das mulheres atuantes na gestão de tecnologias no enfrentamento da pandemia. Destaca-se a pesquisa recente da Associação Brasileira de Engenharia Clínica que verificou que apenas 19% dos associados respondentes eram mulheres, enquanto 81% eram do sexo masculino. Assim, divulgar e dar amplo conhecimento das ações de mulheres nessa área pode colaborar para o alcance da igualdade de gênero e empoderar todas as mulheres e meninas.
Root system architecture and seed weight relations in forage pea (Pisum sativum ssp. arvense L. Poir.)

ABSTRACT: Forage pea (Pisum sativum ssp. arvense (L.) Poir.) is an important legume crop for fresh and dry herbage production with high input costs as irrigation and fertilization. Selection and breeding of accessions for improved drought tolerance, water, and mineral uptake efficiency become a necessity, rather than a choice. This study evaluated a set of forage pea accessions for the seedling root system architecture diversity and seed reserve utilization, under controlled conditions. Eight cultivars and an elite breeding line were evaluated for the first time in a plexiglass system. The number and lengths of the roots in each depth zone (0, 5, 10, 15+ cm) were evaluated and significant diversity was identified. The cultivar Livioletta had the highest number of roots and total root length. There was a significant correlation between seed weight, seed reserve utilization ratio, and root system vigor. Accessions with the highest seed reserve utilization had the highest total root length and numbers. Seedling root system vigor seems to be effective in predicting the fate of the accessions through maturity. The results suggested a possibility of “seedling root selection” for forage crop breeding.
