Published: June 2022

Background.  Bigorexia is an eating disorder and obsessive-compulsive disorder where the subject has an incorrect perception of their body image with exercise addiction. This study aims to determine whether there is a relationship between body mass index (BMI), food supplement consumption, dietary adherence, gender and risk of muscle dysmorphia in the individual and to provide information to build recommendation systems to monitor the health and mental state of the population.

Methods. A cross-sectional descriptive observational study was conducted in Barranquilla (Colombia) between February – May 2020. A face-to-face survey of 200 individuals of both sexes was used in which users evaluated different variables that helped to identify their risk of muscle dysmorphia.  

Results. Of the 200 participants, 105 men: N=48, 45.7% vs. women: N=57, 54.3%) consume nutritional supplements. There is no relationship in the total population with the risk of muscle dysmorphia with the consumption of nutritional supplements nor with the feeling of guilt for non-adherence to the diet, nor with age, gender, or BMI (p<0.05). In contrast, gender, age and BMI are related to nutritional supplement consumption, and gender is related to feelings of guilt for non-adherence to the diet. In the population that consumes nutritional supplements the risk of muscle dysmorphia is increased and the frequency varies by risk group: low risk: N=16, 15.2%; medium risk: N=46, 43.8%; high risk: N=28, 26.7%; and very high risk: N=15, 14.3%. The consumption of food supplements is higher in the female gender (57, 54.3% vs. 48, 45.7%), and moderate the feeling of guilt for not completing the diet, BMI and the risk of muscle dysmorphia.

Conclusions.  Women consume more food supplements, but gender does not determine the risk of muscle dysmorphia. Food supplement consumption influences the feeling of guilt for not completing the diet, BMI and the risk of muscle dysmorphia.
Investigating the effect of e-cigarette use on quitting smoking in adults aged 25 years or more using the PATH study
Authors: Lee Peter N. , Fry John S.
Published: June 2022

Background: The evidence on harms and benefits of e-cigarettes partly concerns whether their use encourages smokers to quit.  We addressed this using data from the nationally representative PATH study, with detailed accounting for potential confounding variables.

Methods: We considered adults aged 25+.  Our original analyses, reported in version 1 of this paper, used data for Waves 1 to 3, separate analyses considering Waves 1 to 2, 2 to 3 and 1 to 3.  These related baseline ever e-cigarette use (or e-product use at Wave 2) to quitting at follow-up, adjusting for confounders derived from 55 candidates.  Sensitivity analyses omitted ever other product users, linked quitting to current e-cigarette use, and used values of some predictors modified using follow-up data.  Additional analyses used data for Waves 1 to 4, separately considering sustained, delayed and temporary quitting during Waves 1 to 3, 2 to 4 and 1 to 4.  Sensitivity analyses considered 30-day quitting, restricted attention to smokers attempting to quit, and considered ever smokeless tobacco or snus use.

Results: In the original analyses, unadjusted odds ratios (ORs) of quitting smoking for ever e-cigarette use were 1.29 (95% CI 1.01-1.66), 1.52 (1.26-1.83) and 1.47 (1.19-1.82) for the Wave 1 to 2, 2 to 3, and 1 to 3 analyses.  These reduced after adjustment, to 1.23 (0.94-1.61), 1.51 (1.24-1.85) and 1.39 (1.11-1.74).  Quitting rates remained elevated in users in all sensitivity analyses.  The additional analyses found associations of e-cigarette use with sustained, delayed and temporary quitting, associations little affected by considering 30-day quitting, and only slightly reduced restricting attention to quit attempters.  Ever use of smokeless tobacco or snus also predicted increased quitting.  

Conclusions: As does most evidence from clinical trials, other analyses of PATH, and other epidemiological studies, our results suggest using e-cigarettes helps adult smokers to quit.

Published: June 2022

This data note aims to present a dataset with values for financing conditions for renewable energy projects in Europe. This includes weighted average cost of capital, cost of debt, cost of equity, debt share, debt service coverage ratio and loan tenors. The dataset was elaborated in the framework of the "Auctions for Renewable Energy Support II" project (AURES II). The main goal of the AURES II project is to provide policy support to the Member States of the European Union in order to improve the effectiveness and cost-efficiency of auctions for renewable energy support. As part of the AURES II project, an extensive survey (structured interviews) was conducted between September 2019 and April 2020 with different stakeholders involved in the renewable energy industry, such as banks, project developing companies, and investment funds, among others. The technologies covered were solar photovoltaics (PV), wind onshore, and wind offshore. Interviewees were asked to provide values for financing conditions for specific projects (for certain cases, country estimates or ranges of values were provided). Spain, Portugal, Greece, Germany, and Denmark were selected as focus countries, for which the interviews also included qualitative questions to discuss the observed quantitative data in these countries. The presented data has been used as the main input to elaborate an AURES II report on renewable energy financing conditions in Europe.
Induction-phase treatment costs for cryptococcal meningitis in high HIV-burden African countries: New opportunities with lower costs

Published: June 2022

Introduction: Access to and the cost of induction treatment for cryptococcal meningitis (CM) is rapidly changing. The newly-announced price for flucytosine ($0.75 per 500 mg pill) and possibly lower prices for liposomal amphotericin B (AmB-L) create opportunities to reduce CM treatment costs compared to the current standard treatment in low- and middle-income countries.

Methods: We developed an Excel-based cost model to estimate health system treatment costs for CM over a two-week induction phase for multiple treatment combinations, newly feasible with improved access to flucytosine and AmB-L. CM treatment costs include medications, laboratory tests and other hospital-based costs (bed-day costs and healthcare worker time). We report results from applying the model using country-specific information for South Africa, Uganda, Nigeria, and Botswana.

Results: A 14-day induction-phase of seven days of inpatient AmB-D with flucytosine, followed by seven days of high-dose fluconazole as an outpatient, will cost health systems less than a 14-day hospital stay with AmB-D and fluconazole. If daily AmB-L replaces AmB-D for those with baseline renal dysfunction, with a cost of $50 or less per 50 mg vial, incremental costs would still be less than the AmB-D with fluconazole regimen. Simple oral combinations (e.g., seven days of flucytosine with fluconazole as an inpatient) are practical when AmB-D is not available, and treatment costs would remain less than the current standard treatment.

Conclusions: Improved access to and lower prices for flucytosine and AmB-L create opportunities for improving CM treatment regimens. An induction regimen of flucytosine and AmB-D for seven days is less costly than standard care in the settings studied here. As this regimen has also been shown to be more effective than current standard care, countries should prioritize scaling up flucytosine access. The cost of AmB-L based regimens is highly dependent on the price of AmB-L, which currently remains unclear.
Status i funkcje rosyjskiej inteligencji w społeczeństwie posttotalitarnym

Status and Functions of the Russian Intelligentsia in Post-totalitarian Society Transition from totalitarian to post-totalitarian type of society requires profound changes not only within institutional frames but also in the mentality of a society. In the case of Russia it is not the matter of coming back to the civil society mechanisms but creating them from anew, as the kind of citizen – state relations had not been spread to the whole society before the Soviet Union times. Intelligentsia could be an agent of the changes towards post-totalitarian state and social order. In this paper questions about the intelligentsia’s status and role in the Russian society were posed. The idea of civil society coined in the times of the Decembrist was confronted with the mobilized type of governing. Intelligentsia, as perceived by the Russian society and experts on the one hand and its selfportrait on the other hand were discussed. An important question concerned the role of the Russian political opposition as the intelligentsia’s ethos continuation. The conclusions were that the intelligentsia repeats the pattern which was first developed at the beginning of the 19th century: its idealistic members are ready to struggle for the common good but without common social support. The status of intelligentsia is perceived as high if about education and morality, but it diminishes when its leadership is concerned. In the Russian post-totalitarian society the state is still an agent to be followed. It takes Russians towards totalitarianism.
Upolitycznienie procesów depopulacji i migracji na Węgrzech po 1989 roku

POLITICIZATION OF DEPOPULATION AND MIGRATION PROCESSES IN HUNGARY AFTER 1989 Hungary’s population count has been declining since 1981. And if this trend continues, the country will have only 6 million inhabitants by 2070. The Fidesz administration, which has been in power continuously since 2010, has taken decisive steps to act against this trend. The population of Hungary is dropping by 40,097 people annually, which corresponds to the disappearance of a mediumsized city in one year. Hungary was the first country in Europe after the Second World War where the fertility rate fell below the level of simple population replacement, i.e. below 2.1 births per woman. Since the end of the 1980s, the population number has been declining by around 0.15-0.20 percent per year, and today the fertility rate in Hungary is one of the lowest in Europe. The Hungarian age structure will become more and more problematic as the fertile age group of the population continues to shrink. The explanation of these phenomena is the significant emigration of the native population and the complicated immigration policy. The authorities are trying to reverse this trend by introducing many legal and fiscal facilitations to encourage young people to have many children (in 2012, Hungary registered the lowest employment rate among women in the entire European Union).

SOME PROBLEMS ASSOCIATED WITH THE MAJORITY OF VOTES REQUIRED FOR AMENDING THE 1997 CONSTITUTION OF POLAND
The aim of this paper is to supplement the findings made by the doctrine of constitutional law regarding the requirements of the majority of votes for amending the 1997 Constitution of Poland at the parliamentary stage of that procedure. The following issues will be analysed in particular: the significance of constitutional amendment rules in a democratic system of government and their impact on its rigidity and durability; the role of the quorum as a factor contributing to the majority of votes’ requirements and some political dilemmas associated with that matter; the reasons and consequences of adopting different levels of the majority of votes for amending the Constitution in the Sejm and the Senate and their relation to the form of the relationships between those chambers. Regulations regarding amending the 1997 Constitution of Poland will be presented against a background of contemporary constitutions of European states. The important interpretative context will be constituted by the issues of axiology of democracy, parliamentary bicameralism and legitimization of power.
Temporary Accommodation Facilities for People Affected by an Emergency or Humanitarian Disaster
Authors: Cygańczuk Krzysztof , Roguski Jacek , Tępiński Jarosław
Published: June 2022

Aim: This article attempts to provide an insight into the planning and construction of temporary accommodation for those affected by warfare and hu- manitarian disasters. The damage to housing infrastructure is often very extensive and its reconstruction takes up to several years, during which time it is necessary to provide refugees and disaster victims with minimum living conditions until they are able to move into permanent housing facilities. The article further describes the planning process that should be followed before disasters, as well as the types of temporary accommodation and the use of local resources in disaster recovery. Introduction: In recent years, we have seen a significant increase in the occurrence of natural disasters and local armed conflicts. In most cases in- frastructure in disaster areas is severely damaged or completely destroyed. Houses and residential buildings are very vulnerable to damage and are the most visible consequence after disasters. At the same time, for the people affected by these disasters, they are very traumatic experiences. The article describes the key role of temporary housing during the recovery from humanitarian disasters, identifies common problems and provides some suggestions on how to overcome them. Methodology: The paper mainly uses theoretical research methods, including literature analysis and the opinions of international experts who have conducted studies of many humanitarian disasters and warfare. The analysis which was carried out made it possible to establish and present directions for the construction methodology and optimal solutions in the refugee accommodation project. It discusses elements that can be classified as common patterns of temporary accommodation and reviews of both successful and unsuccessful solutions. Conclusions: The article discusses important factors related to humanitarian disaster preparedness and management. In order to assess the prepared- ness of planning and disaster management, the article answers the following questions: what is good planning and management and what is the role of temporary housing? The answer is based on the results of empirical and behavioural research conducted by international experts and UNDRO – the United Nations Disaster Relief Organization and the United Nations High Commissioner for Refugees (UNHCR).

Possibilities of Using Mobile Fans and the Parameters Conditioning the Effectiveness of Tactical Mechanical Ventilation
Authors: Kaczmarzyk Piotr , Janik Paweł , Klapsa Wojciech , Bugaj Grzegorz
Published: June 2022

Aim: The aim of the article is to indicate the possible scope of application of mobile fans during the execution of rescue actions and identification of the parameters conditioning the effectiveness of using this type of units. Method Design: Mobile overpressure fans are a tool used during rescue operations mainly to remove hot gases and smoke, which accumulate in confined spaces covered by fire – primarily within the evacuation routes, but also in the rooms. In literature there are examples of other uses of the considered fans, e.g. to support the liquidation of fire hazards of free-standing objects (i.e. fires of cars or containers) and the rescue of trapped people in inaccessible spaces by supplying fresh air. This paper, which is based on literature review, is devoted to providing an approximation of the above applications. The effective use of mobile fans requires specialized theoretical and practical preparation. Therefore, the study also identified factors that may determine the successful implementation of the adopted tactical intent, which include in particular: the selection of appropriate openings (outlet and inlet), the selection of the gas exchange path and the proper positioning of a mobile fan. Conclusions: Literature analysis of the problem presented in this paper will be a fundamental point of reference for the research work carried out in subsequent stages related to the evaluation of the efficiency of mobile fans. As part of this work, large-scale tests will be carried out using appropriately designed and constructed test benches to evaluate the effectiveness of mobile units in real conditions. The knowledge gained in this way is intended to serve as material for further considerations on the creation of concepts of both subsequent methodologies and test stands required for their implemen- tation, enabling the verification of parameters characterizing the efficiency and reliability of mobile fans.

Fire Resistance of Aluminum-Glass Partitions with a Parallel Structure of Intumescent Layers
Authors: Gwóźdź Marian , Marcinowski Michał
Published: June 2022

Aim: The aim of the article is to verify the fire resistance of aluminum-glass construction partitions with a parallel structure. The paper presents the results of tests in a fire chamber of a selected partition, a leading national manufacturer of aluminum-glass systems. The results of the fire tests were used to validate a simple parallel model of the reliability of non-renewable systems. Introduction: Fire-retardant properties of partitions made of glass and aluminum profiles determine their ability to stop the spread of fire by clos - ing the fire in separate zones. Fire resistance of such partitions is measured according to various criteria, in particular the requirements concern: stability R (glass does not break), tightness E, radiation limitation W and insulation I. The tightness requirement E means that the partition effectively protects the fire compartment against flames, smoke and hot gases. The insulating postulate I means that the average temperature of glass and the profiles on the surface of the partition on the protected side does not exceed the contractual value during the nominal duration of the fire. The measure of fire resistance of a partition is time t, expressed in minutes, in which the structure of an aluminum-glass partition meets one or more of the criteria listed. Methodology: The experimental database consists of the results of routine fire resistance tests of system building partitions obtained in the certification process of selected facade systems. Interpretation of the obtained results of laboratory tests was based on simple models of reliability of non-renewable systems. Conclusions: The graphs of average temperature increase on the outer surface of the tested glass are the same in each case in terms of quality and quantity. Up to about 70% of the nominal fire resistance, the temperature increase is linear, followed by a non-linear phase according to a concave curve. The course of the temperature-rise curves on the outer surface of aluminum profiles is qualitatively different. The graphs are non-linear, convex from the beginning of heating, with the inflection point reached after about 20 minutes of the test. The obtained results may indicate that the multi-chamber structure of aluminum profiles does not ensure a parallel reliability structure, because the object has a quasi-parallel structure. The presented results of the temperature-rise curves and their reliability interpretation require confirmation in further laboratory tests of aluminum-glass partitions with a different structure of panes and profiles.

Published: June 2022

Introduction: The transport of patients by airplanes or helicopters reduces treatment time, while improving the chances of survival and the quality of life. Due to its costly maintenance and operation service, the air transport of victims depends on appropriate triage criteria for patients eligible for this type of transport. The Air Medical Prehospital Triage (AMPT) Score for Helicopter Transport of Trauma Patients quickly classifies the likelihood of trauma victims benefiting or not from helicopter transport. Objectives: The aim of this study was to translate the AMPT Score and cross-culturally adapt it to Brazilian Portuguese. Methods: This study followed international guidelines for standardized translation processes and was developed from: translation, synthesis, back translation, assessment of equivalences by the expert committee, proposal of the previous version of AMPT Score, application of pre-test/post-test and proposition of the final version of the translated scale. Results: The Wilcoxon Test comparing the experts’ assessment with the positive expected resulted in a p-value = 0.0625 (General) CI 95%. The Content Validity Index (CVI) of the experts committee was calculated as 0.9479. The pre-test data resulted in a Cronbach’s Alpha of 0.920 ± 7.26. The free-marginal Kappa coefficient of pre-test data was 0.89 (95% CI for 0.86, 0.93).The post-test data resulted in a Cronbach’s Alpha of 0.925 ± 5.36. The Wilcoxon Test comparing pre-test with post-test resulted in a p-value of 0.0942. Conclusions: The process resulted in a translation of the AMPT Score with the appropriate equivalences proposed by the literature that is statistically reliable and will be of great value to professionals who work with transporting trauma victims in helicopters. Keywords: Prehospital care; Air ambulances; Helicopter; Triage; Translation.

Published: June 2022

Background: Myelodysplastic syndrome (MDS) comprises a heterogeneous group of clonal hematopoietic stem cell diseases, characterized by dysplasias and apoptosis in bone marrow (BM) and cytopenias in peripheral blood. In this study, we analyzed apoptosis in MDS to verify associations with patient age, bone marrow cellularity and karyotypes and to investigate the role of apoptosis in MDS pathogenesis. Methods: Bone marrow cells were collected from 81 patients with primary MDS, of which 60 were adults and 21 children. BM cells were also collected from 10 healthy donors for bone marrow transplants, 5 adults and 5 children, as controls. The patients and controls came from public onco-hematology institutions in Rio de Janeiro. The percentage of apoptotic BM cells was assessed by flow cytometry using two combinations: annexin V-FITC/CD34PE/CD45PerCP and annexin V-FITC/CD14PE/CD45PerCP in BM cells. Cytogenetic analysis was performed by G-banding. Results: The comparison between adult and pediatric patients showed that these patients show a similar behavior with regard to apoptotic cells percentages in BM samples. Apoptosis occurs independently of BM cellularity, being more prominent in patients with hyper/normocellular BM. Patients with normal karyotypes, del(5q), del(17p) had higher apoptosis rates than patients with del(11q) and complex karyotypes. Cells committed to a differentiation program were associated with high rates of apoptosis, suggesting that apoptosis may be a consequence of inefficient hematopoiesis, such that the hematopoietic system may eliminate dysplastic cells at the beginning of the disease. Conclusions: Our results suggest that apoptosis is an important characteristic of BM cells from adult and pediatric MDS patients and may be a consequence of inefficient hematopoiesis. In addition, we suggest that apoptosis is not the main mechanism associated with hypocellular MDS, and it occurs preferentially in MDS cases of hyper/normocellular BM and is associated with a good prognosis. Keywords: Myelodysplastic Syndrome; Apoptosis; Patient age; Bone marrow cellularity; Karyotypes.

Published: June 2022

Objective: To determine the serum level of C-reactive protein (CRP) with greater accuracy for diagnosing acute periprosthetic infection after total knee arthroplasty (TKA). Method: Case-control study evaluating serum levels of CRP after TKA in infected and uninfected groups. The serum levels of CRP were assessed in patients submitted to TKA who had been readmitted in the acute phase for surgical debridement with implant retention and had their diagnosis of periprosthetic infection confirmed. These values were compared with a control group, which did not present infectious complications. Results: Between March 2014 and March 2016, 1,373 TKAs were performed in the institution, and 28 patients (0.49%) were readmitted in the acute phase with a diagnosis of periprosthetic infection. Sixteen patients met the inclusion criteria. Gender, skin color, age, and body mass index (BMI) were similar between the groups. The patients in the acute periprosthetic infection group had significantly higher mean serum levels of CRP than the control group (p<0.001). For CRP levels = 30.615, the test's highest sensitivity (75%) and specificity (77%) were achieved, with an accuracy of 77.3% for the diagnosis of infection. The area under the 0.762 Receiver Operating Characteristics (ROC) curve showed satisfactory performance of the proposed test. Conclusion: Serum levels of CRP greater than 30.615 mg/L in the third week after TKA associated with clinical signs are highly suggestive of acute periprosthetic infection.Keywords: Knee; Osteoarthritis; Arthroplasty; Infection; CRP.*Study performed at the Centro de Cirurgia do Joelho, Instituto Nacional de Traumatologia e Ortopedia (INTO), Rio de Janeiro, RJ, Brazil.
Expenditures on the treatment of encephalon malignant neoplasia by the Brazilian public health system (2008-2017)
Authors: Garcia Carlos G. , Nespoli Joice
Published: June 2022

Introduction: Encephalon malignant neoplasia (EMN) is a harmful type of cancer and its most aggressive phenotypes lead to the demise of patients in 12-18 months despite the use of state-of-the-art therapies, which remain inefficient and expensive for patients, families and health systems. Objectives: The aim of this work was to analyze the expenditures of the Brazilian Sistema Único de Saúde (SUS), the national public health system, on EMN patients compared to all neoplasia patients over a span of ten years (2008 to 2017). Methodology and resources: Monthly data were collected from the SUS data base DATASUS from 2008 to 2017 and analyzed with regard to EMN and general neoplasia for the following categories: value of total expenditures; number of hospitalizations; mean value of hospitalizations; mean of monthly permanence time and death rate. Results: More than 0.3% of SUS costs were directed to EMN patients, although they represented 0.1% of total hospitalizations. The mean value of hospitalization of EMN patients was almost 80% that of general neoplasia patients and hospitalization time was twice that of general neoplasia patients. Moreover, EMN patients had a death rate almost four times higher than that of general neoplasia patients. Discussion and conclusion: EMN therapies remained expensive and lacked efficacy in the time period under analysis, with a disproportionate share of SUS expenditure being dedicated to these patients. Improving the effectiveness of treatment requires drug repurposing and adjuvant chemotherapy—in addition to radiotherapy and the use of monoclonal antibodies.Keywords: Encephalon malignant neoplasia; Cancer treatment costs; SUS.

Introduction: The emergence of a new coronavirus has changed the world and caused one of the biggest global health crises of the past 100 years. The protagonist of the pandemic, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is responsible for the coronavirus disease 2019 (Covid-19), which leads to dysfunctions in a plethora of systems, especially in severe cases. Therefore, researchers and healthcare professionals are making great efforts to develop a therapy that helps the many organs affected by the disease, for which mesenchymal stem cells (MSCs) arise as promising candidates. MSCs can offer benefits at different phases of Covid-19, since they have important anti-inflammatory and tissue repair properties. Objective: This review aims to elucidate how MSCs can contribute in the Covid-19 scenario by considering their properties and mechanisms of action. Methods: A review of the scientific literature was conducted on electronic databases, such as PubMed, Scielo and Web of Science, in the period of 2020-2021. Results: Therapeutic effects of MSCs in preclinical models of respiratory, nervous, renal, and cardiovascular systems were observed. Conclusion: MSCs can be a therapeutic resource for patients with severe Covid-19.Keywords: SARS-CoV-2; Covid-19; Mesenchymal stem cells; Immunomodulation; Cell therapy.

Published: June 2022

Introduction: Communication is important to ensure safety in demands regarding patients, processes and staff in intensive care units (ICUs), a complex area that requires good communication and dynamism in order to achieve positive results for patients. Hence, the identification of tools that may provide improvements in communication among professionals working in the ICU in the scientific literature is essential. Objective: To map in the literature the types of tools for improving communication among professionals in intensive care. Method: Rand integrative vision performed between April and May 2021, with searches in the medline, LILACS and BDENF databases. We used the descriptors: “Patient Safety”; “Intensive Care Units”; “Applications of Medical Informatics”, with Boolean operator “AND”. The search covered articles published between 2016 and 2021, full texts, in the Portuguese, English and Spanish languages. Duplicates, case reports, annals, editorials, letters to the editor, dissertations and theses were excluded. Results: We identified two categories: tools for changes of shift and tools for transfers of care. Conclusions: Communication tools are effective because they reduce the incidence risk of errors in direct patient care.Keywords: Patient safety; Health communication; Intensive Care Units; Applications of medical informatics.

Resumo: Este artigo constitui um ensaio que tem por objetivo refletir sobre a educação inclusiva e seus preceitos, estabelecendo uma relação com alguns pressupostos teóricos do educador Paulo Freire e oferecendo espaço para uma releitura da educação inclusiva em seu sentido mais amplo. Aponta-se que as contribuições de Paulo Freire para a Educação não ficam restritas apenas à alfabetização de jovens e adultos, mas oferecem suporte teórico e prático para reflexões profundas em quaisquer outros contextos educacionais, nos quais o processo ensino/aprendizagem seja visto como elemento possível de constituição de sujeitos autônomos e de novos e diferentes saberes. Encontra-se em Paulo Freire possibilidades de articulação com a educação inclusiva à medida que o autor questiona todo e qualquer processo de exclusão escolar e social e referenda que a escola é direito de todos e deve ser um espaço democrático e dialógico.Palavras-chaves: Educação.

It is pointed out in this text that Paulo Freire's contributions to education are not only restricted to youth and adult literacy. But offer theoretical and practical support for deep reflections in any other educational context where the teaching/learning process is seen as an element autonomous subjects and new and different knowledge. We find in Paulo Freire possibilities of articulation with inclusive education as the author questions any and all processes of school and social exclusion and says that school is the right of all and should be a democratic and dialogical space.Keywords: Education.

Aims

Hip and knee arthroplasty is commonly performed for end-stage arthritis. There is limited information to guide golfers on the impact this procedure will have postoperatively. This study aimed to determine the impact of lower limb arthroplasty on amateur golfer performance and return to play.

Methods

A retrospective observational study was designed to collect information from golfers following arthroplasty. Data were collected from 18 April 2019 to 30 April 2019 and combined a patient survey with in-app handicap data.

Results

A total of 2,198 responses were analyzed (1,097 hip and 1,101 knee). Of the respondents, 1,763 (80%) were male and the mean age was 70 years (26 to 92). Hip arthroplasty was associated with a mean increase in handicap of 1.03 (95% confidence interval (CI) 0.81 to 1.25). No difference was seen between isolated leading or trailing leg (p = 0.428). Bilateral hip arthroplasty increased handicap (p < 0.001). Overall, 1,025 (94%) maintained or increased the amount of golf played, 258 (23.5%) returned to iron shots at six weeks, 883 (80%) returned to club competitions at six months, 18 (1.6%) had persistent pain, and 19 (1.7%) were unable to return to play. Knee arthroplasty was associated with a mean increase in handicap of 1.18 (95% CI 0.99 to 1.38). Trailing leg arthroplasty alone was associated with higher postoperative handicap (p = 0.002) as was bilateral surgery (p = 0.009). Overall, 1,009 (92%) maintained or increased the amount of golf played, 270 (25%) returned to iron shots at six weeks, 842 (76%) returned to club competition at six months, 66 (6%) had persistent pain, and 18 (1.6%) were unable to return to play.

Conclusion

Hip and knee arthroplasty enables patients to maintain or increase the amount of golf played. The majority return to competitions within one year. Return to iron shots occurs from six weeks. A small increase in handicap following surgery is expected and is larger in patients undergoing bilateral surgery or those with knee arthroplasty to their trailing leg. Patients may still experience pain when playing golf. Cite this article: Bone Jt Open 2022;3(6):510–514.
Aerial images to monitor grapevine vegetative growth
Authors: Pereira Janielle Souza , Ferraz Gabriel Araújo e Silva , Santana Lucas Santos
Published: June 2022

Images obtained by Remotely Piloted Aircraft (RPA) used to monitor the crop can help evaluate leaf mass, plant formation, and plant population. In this context, the objectives of this study were to analyze plant growth in a grapevine crop trained in the trellis system, detect failures and determine the plant covered area using images obtained by RPA. The flight was parameterized with frontal overlap of 75%, lateral overlap of 70%, Ground Sample Distance (GSD) of 60 m, and flight speed of 5 m.s-1, using a sensor in the visible range. Processed images showed a stand 3% smaller than projected, an area covered by vine branches occupying 60.8%, undergrowth and invasives represented 5.3%, and exposed soil 33.9%. Vines were identified in the vegetation indices as green points, invasive plants as yellow points, and exposed soil as red points. Image processing obtained with RPA allowed identification of plants in various stages of development, with predominance of vines in the formation process. It was possible to identify the plants and quantify the leaf mass using the MPRI vegetation index, as well as to differentiate exposed soil from plant material. It was also observed that the plot had an incomplete stand at the time the flight was performed.
New-World Spread of the Old-World Robust Crazy Ant, Nylanderia bourbonica (Forel) (Hymenoptera: Formicidae)
Authors: Wetterer James Kelly

The robust crazy ant, Nylanderia bourbonica (Forel) (formerly Paratrechina bourbonica), is native to the Old-World tropics and subtropics. Its earliest known record in the New World was collected in 1924 in Miami, Florida. Here, I examine the subsequent spread of this species to other parts of North America and the West Indies. I compiled published and unpublished New World N. bourbonica specimen records from 446 sites, documenting the earliest known records for 24 geographic areas (countries, island groups, major islands, and US states), including nine for which I found no previously published records: Anguilla, Antigua, Barbuda, British Virgin Islands, Jamaica, Turks and Caicos Islands, Missouri, New York, and Washington. The vast majority of New World site records for N. bourbonica (89%) come from Florida, where this species is now known from 37 counties. Most, if not all, of the 14 site records of N. bourbonica in North American north of 30.5°N come from indoors. Although the earliest record of N. bourbonica from Cuba dates to 1933, the spread of N. bourbonica to many West Indian islands appears to be much more recent. In Florida, N. bourbonica is a widespread, though relatively minor household and agricultural pest, and also is common in some more natural environments. It remains to be seen whether N. bourbonica will become a significant pest in the West Indies or elsewhere in the New World.
First record of Temnothorax convexus (Forel, 1894) in Portugal (Hymenoptera: Formicidae) with an updated checklist of the ants from the country

The Iberian Peninsula holds one of the richest myrmecofauna of the Mediterranean basin, but some regions such as Portugal remain comparatively undersampled. Although new unrecorded species have been regularly found and published during the last two decades, the sum is still far from approaching the more than 300 species known to occur in the Iberian Peninsula. In this context, the arboreal ant Temnothorax convexus (Forel, 1894) is reported here for the first time in Portugal. A complete society was found nesting inside an abandoned gall of Andricus quercustozae (Bosc, 1792) near Lisbon. A full morphometric evaluation of the specimens is provided, including a small sample from the recently discovered population in South Iberia. High-definition photographs of the worker caste are presented, together with a comparison with the most similar species in Iberia. Finally, a critical update of the Portuguese ant checklist is provided, discussing the most recent nomenclatural changes and taxonomic issues, rising the final species number to 132.
Photonics based frequency hopping spread spectrum system for secure terahertz communications

Terahertz (THz) spectrum (100 GHz-10 THz) is considered the next frontier in the design of high-speed wireless communication systems. While the high-power THz sources have commercially become available, it increases the possibility of developing THz jammers to disrupt the THz communication link. Therefore, the development of novel anti-jamming solutions is the need of the hour. In this work, we present the photonics-based THz communication system and demonstrate the frequency hopping spread spectrum (FHSS) technique which acts against the single/multi-tone jamming attack in the frequency window of 110 GHz-170 GHz. By tuning the output wavelength of the distributed feedback lasers, the THz carrier frequencies are swept back and forth within the scanning window. The frequency tuning range was measured for different scanning rates of the laser which decreases rapidly with the increase in the scanning rate. Next, we demonstrate the THz FHSS technique in a real-time communication system by transmitting a 6 Gbps NRZ signal in both wireless and THz-fiber-based links within the link distance of 1.75 m. We experimentally found that the measured bit error rate in the THz FHSS system is the time average of the measured BER for individual carrier frequencies within the hopping frequency window. By combining with the forward error correction codes and by using the tunable filter in the receiver, we believe that the proposed technique will offer a novel and compact solution against the single/multi-tone jammer for high-bit rate THz communications.
In-orbit geometric calibration of multi-linear array optical remote sensing satellites with tie constraints

When some sub-images lack ground control points (GCPs) or GCPs are not evenly distributed, the estimated camera parameters are often deviated in in-orbit geometric calibration. In this study, a feasible in-orbit geometric calibration method for multi-linear array optical remote sensing satellites with tie constraints is presented. In the presented method, both GCPs and tie points are employed. With the help of tie constraints provided by tie points, all charge coupled devices (CCDs) are logically connected into a complete CCD. The internal camera parameters of all CCDs can then be simultaneously and precisely estimated, even if sufficient evenly distributed GCPs in some sub-images are unavailable. Three GaoFen-6 images and two ZiYuan3-02 images were tested. Compared with the conventional method, the experimental results showed that the deviations of the estimated camera parameters could be effectively eliminated by the presented method. The average geometric stitching accuracy of the adjacent sub-images of all the tested images were improved from approximately 0.5 pixel to 0.1 pixel. The geometric quality of the stitched images was thereby improved.
