Resumo Objetivo Investigar a presença de infecção cervical pelo papilomavírus humano (HPV, human papillomavirus) em mulheres idosas e fatores relacionados. Método Trata-se de um estudo transversal, retrospectivo e descritivo, com abordagem quantitativa. A amostra foi constituída por 106 mulheres com idade igual ou superior a 60 anos atendidas em serviços de saúde pública de uma cidade do Sul do Brasil, as quais realizaram coleta de material cervical para análise citológica e detecção molecular do DNA do HPV, bem como levantamento de dados clínicos e sociodemográficos por meio de um questionário padronizado e requisição do exame citopatológico. Resultados A idade das pacientes variou entre 60 e 82 anos, com média de 64,9 ± 5,1. O HPV foi detectado em 14 (13,2%) idosas avaliadas no estudo e 8 tipos virais foram identificados, a maioria (n=7; 87,5%) de alto risco oncogênico. Observou-se, por análise de qui-quadrado, que casos HPV positivos possuem associação com maior número de parceiros sexuais (p= 0,018). Na citologia, a maioria das mulheres (n=102; 96,2%) apresentou resultado negativo para lesão intraepitelial ou malignidade e duas (1,8%) apresentaram citologia alterada, mas destas, nenhuma apresentou infecção por HPV no teste molecular. Das 10 mulheres avaliadas em duas visitas, sete (70%) não apresentaram infecção pelo HPV em ambas as avaliações, duas (20%) eliminaram a infecção pelo HPV e uma (10%) apresentou conversão para positividade. Nenhuma delas apresentou infecção persistente. Conclusão Mulheres idosas estão suscetíveis à infecção por HPV e às lesões causadas por esse vírus, por isso devem manter o rastreamento citológico.

Resumo Objetivo Analisar os fatores associados ao comportamento sedentário em pessoas idosas. Método Estudo transversal, com dados da Pesquisa Nacional de Saúde, 2019 com 22.728 pessoas idosas do Brasil. O desfecho foi o comportamento sedentário e as exposições: características sociodemográficas, estilo de vida, características do domicílio e doenças crônicas. Foi empregada a regressão logística múltipla e um nível de significância de 5%. Resultados A prevalência do comportamento sedentário foi 32,8% (IC95%: 31,8-33,8).Verificou-se maior chance para o desfecho no sexo feminino (OR =1,20; IC 95%: 1,08-1,34), entre as faixas etárias de 70 a 79 anos (OR = 1,22; IC 95%: 1,09-1,36) e 80 anos ou mais (OR=1,18; IC 95%: 1,02-1,36); entre pessoas idosas quem não tem companheiro (OR= 1,27; IC95%: 1,14-1,41); diabéticos (OR =1,17; IC 95%: 1,06-1,30), hipertensos (OR =1,34; IC 95%: 1,18-1,51), naqueles que tiveram Acidente Vascular Cerebral (OR = 1,61; IC 95%: 1,32-1,96) e naqueles que não têm lugar para praticar atividade física próximo do domicilio (OR =1,16; IC95%:1,05-1,29). Pessoas idosas com baixa escolaridade (OR = 0,71; IC 95%: 0,61- 0,82), e residentes em zona rural (OR = 0,53; IC 95%: 0,47-0,61) possuem menores chances de comportamento sedentário. Conclusão Mulheres, maiores faixas etárias (a partir dos 70 anos), pessoas com diabetes, hipertensão e que já tiveram AVE, e que não possuem locais para prática de atividade física próximo à residência foram associados à elevada exposição ao comportamento sedentário. Enquanto, viver em zonas rurais e possuir menor escolaridade apresentaram associação inversa a esse comportamento de risco.

Abstract Objective To verify the prevalence of potentially inappropriate medications (PIM) in use and possible associated factors in older adults and the agreement between two assessment tool in Primary Health Care (PHC) contex Methods Cross-sectional study. The prevalence of older adults in use of PIM and associated factors were estimated. First of all was calculated the frequency of drugs, among those used, considered PIM. Classification as PIM was based on the 2019 Beers Criteria and the 2016 Brazilian Consensus on Potentially Inappropriate Medications 2016 (BCPIM) for the older adults. The agreement between the two classifications was also evaluated. Multivariate logistic regression models were estimated. Association was evaluated by Odds Ratio (OR). Kappa was calculated for agreement between both classifications. Results The prevalence of older adults using MPI was 32.9%, according to Beers Criteria and 27.6% according to the BCPIM. The reports of diabetes (OR=1.96), depression (OR=2.25) and polypharmacy (OR=4.11) were associated (p<0.001) with the use of inappropriate medication, according to the Beers Criteria. Older adults who were very satisfied with their own health were less likely to use inappropriate medication both according to the Beers Criteria (OR=0.02) and the BCPIM (OR=0.09). Agreement between classifications was considered good (k=0.75, p<0.001). Conclusion Reports of diabetes and depression, polypharmacy and negative self-rated health and satisfaction were associated with PIM’s use. The associations were similar between the two classifications, indicating that both are relevant in identifying PIM use in older adults in the context of PHC.

Abstract Objective: This qualitative, cross-sectional study aimed to understand the social representations of obesity and the weight loss process in women who underwent bariatric surgery. Methods: Sixteen post-bariatric surgery (between 3 and 12 months post-surgery) women participated in semi-structured, face-to-face and individual interviews. The Thematic Analysis of Braun and Clarke (2006) was carried out to evaluate the data. Results: It were identifying 15 codes, 11 sub-themes, grouped into 3 themes: 1) Obesity: “The monster of contemporary society”; 2) “Today is different from what it was before”: Re-signifying eating; and 3) I’m happy, very happy”: The emergence of a new life. It was observed that the low tolerance to obesity in contemporary times implies the perception that people with obesity not worthy living in society. Thus, bariatric surgery is seen as the solution to the problem, as a way to feel ‘normal’ and visible, through a more socially accepted body. Conclusion: The discourse on health, linked to physical limitations, as the main justification for performing the surgery, seems to be overlaid by esthetic issues in the weight loss process.

Abstract Objective: Aimed to map the constructs used in articles to discuss the mental health of undergraduate nursing students in a positive perspective. Methods: A scoping review was carried out with a search in the electronic databases: Scopus, Latin American and Caribbean Health Sciences Literature and Cumulative Index to Nursing and Allied Health Literature, in April 2020, which allowed retrieval of 286 articles. Data selection and extraction was performed in a double check by the group investigators and were assessed using the continuous data comparison technique. Results: We selected 53 articles that allowed detecting a set of 13 constructs associated with positive mental health that are continuously investigated by this audience. Conclusion: It was found that the mental health of undergraduate nursing students is a supportive set of characteristics conditioned to the inter-retroactive circuit, in which each component retroacts on each part of a set of strengths, fostering a dynamic state of internal balance.

Abstract Brazil is among the countries that most use pesticides in the world. These chemicals cause undesirable changes in ecosystems, particularly the contamination of non-target native forest species through drift. The nuisances caused by pesticides go beyond environmental damage and include public health problems. The objective of this work was to evaluate the effects of glyphosate on leaf gas exchange, photosynthetic pigments and morphoanatomy of seedlings of Eugenia dysenterica. The visual toxicity, physiological and morphoanatomical characteristics of E. dysenterica, when exposed to concentrations of 0, 550, 1110 and 2220 g a.e. ha-1 of glyphosate, were analyzed. The results indicate that the herbicide caused toxicity in the leaves in all treatments. Reductions in photosynthesis (A), stomatal conductance (gs), and transpiration (E) at 47 DAA, were also identified. Glyphosate caused damage to the anatomical structures of E. dysenterica leaves. From the data analyzed it is possible to affirm that plants of E. dysenterica are sensitive to the action of glyphosate. Visible symptoms such as chlorosis and necrosis in the leaf edge are indicators that can be used by rural communities as a warning of the risk of contamination.

Abstract The relocation of epiphytes contributes to biodiversity conservation. In this sense, studies that aim to promote the success of the process are necessary. Therefore, the objective of this work was to analyze the effects of initial fresh mass and fertilization on the propagation of two species of Rhipsalis, thus ensuring their success after relocation to a protected area. Therefore, fertilized and unfertilized plants of Rhipsalis puniceodiscus and Rhipsalis trigona initially with one or two cladodes were propagated in a greenhouse for 25 months. After relocation to a forest area, their survival was monitored for 16 months. Survival percentage, shoot length and root length were analyzed every four months. Fresh mass, dry mass and photosynthetic pigment were analyzed before relocating to a native forest. During the protected propagation stage, for both species, individuals presenting more branches and those that were fertilized exhibited more intense overall development. The propagation of R. puniceodiscus and R. trigona in a greenhouse with two cladodes is better than with one cladode. In general, R. puniceodiscus displayed better development under controlled conditions than R. trigona. Propagation using fertilization increased fresh mass and favors growth and survival rate of R. puniceodiscus and R. trigona. It is possible to relocate both species to a preserved area of the Atlantic Forest, but R. trigona presented more potential.

Published: August 2023

RESUMO Introdução: A resposta imune a diferentes vacinas contra a doença do coronavírus 2019 (COVID-19) é pouco investigada em pacientes com doença renal em estágio terminal (DRET), especialmente no Oriente Médio e norte da África. Realizamos esta pesquisa para estimar a eficácia da imunização contra a COVID-19 em pacientes com DRET em hemodiálise regular (HD). Métodos: Nesse estudo observacional prospectivo, inscrevemos 60 pacientes com DRET em HD regular que haviam concluído o esquema de vacinação contra a COVID-19 e 30 participantes saudáveis vacinados. Os níveis séricos de imunoglobulina G da síndrome respiratória aguda grave do coronavírus 2 (SARS-COV2 IgG) foram quantificados um mês após a conclusão do esquema vacinal, e todos os participantes foram acompanhados de outubro de 2021 a março de 2022. As vacinas utilizadas no estudo eram da Pfizer-BioNTech, AstraZeneca e Sinopharm. Resultados: O nível mediano de SARS-COV2 IgG foi menor em pacientes em HD do que em participantes saudáveis (p < 0,001). Com relação ao tipo de vacinação contra a COVID-19, não houve diferença estatística nos níveis de SARS-COV2 IgG entre pacientes em HD. Durante o período de observação, nenhum dos pacientes em HD teve COVID-19. Conclusão: A vacinação contra a COVID-19 pareceu ser eficaz na proteção de pacientes em HD por 6 meses e os efeitos colaterais das vacinas foram toleráveis.

Evaluation of shear rate formulations through steady uniform non-Newtonian fluid flows in the context of shallow-water equations
Authors: Sáo Yuri Taglieri , Pereira João Batista , Maciel Geraldo de Freitas
Published: August 2023

ABSTRACT Non-Newtonian rheology effects, such as pseudoplasticity and viscoplasticity, are understood as shear stresses, incorporated to the energy slope term in the Shallow-Water Equations (SWE). However, non-Newtonian shear stresses are dependent of the shear rate, whose formulation is a function of the gradient of the velocity profile in the bottom. This study investigated two shear rate formulations that are commonly applied in the SWE literature: 1) a non-parameterized function; and 2) a function based on the Herschel-Bulkley rheological model. Their influence in steady uniform flows of non-Newtonian fluids was evaluated through numerical-theoretical comparisons. A Lax-Friedrichs scheme was implemented to solve the SWE system and allowed employing the shear rate formulations. Experimental tests were carried out and numerical simulations of hypothetical scenarios were performed. It was found that the non-parameterized formulation presented deviation in normal depth up to 14% in comparison with theoretical solution, while the formulation based on the Herschel-Bulkley model provided a good agreement, corroborated by punctual Computational Fluid Dynamics simulations (deviation less than 2%) and experimental data. The ratio of both shear rate formulations is strongly correlated to the deviation of normal depth, indicating that the non-parameterized shear rate function does not provide an acceptable result in the steady uniform flow.
Comparing and measuring the practice-based performance and competence of occupational therapy students between traditional and role emerging placements: a retrospective cohort study
Authors: Thew Miranda , Cruz Daniel Cezar da , Thomas Yvonne
Published: August 2023

Abstract Introduction Increasingly occupational therapy programmes have complemented traditional practice placements with Role Emerging Placements (REPs) in settings with no existing occupational therapy provision. Previous research has predominantly explored the student experience of such placements with largely favorable findings. However, there is a lack of understanding regarding the professional practice-based skills students develop within REPs. Objective To measure and compare students’ competencies for occupational therapy practice developed within Role Emerging Placements (REP) to those in ‘traditional’ practice placements. Method A retrospective cohort study design was used to analyze data extracted from the Competency Based Fieldwork Evaluation for Occupational Therapists (CBFE-OT) of MSc pre-registration occupational therapy UK students (n=181). Descriptive and inferential statistical analysis measured and compared student fieldwork competency scores between four placements, one of which was a Role Emerging Placement (REP). Results Students scored significantly higher in ‘Communication’ and ‘Professional Interactions’ compared to all other practice competencies but scored significantly less well in ‘Clinical Reasoning’ and ‘Practice Knowledge’ regardless of placement model. However, in a REP, students scored significantly higher in ‘Performance Management’ compared to traditional placements (z=-2.222 p=0.026). Conclusion Students can develop similar skills of competence to practise in a REP as traditional placements and may better develop leadership and time management skills. These additional skills may advantage students in developing their careers and scoping the profession.

Published: August 2023

Abstract This study aimed to redescribe two species of Ozolaimus, parasites of free-living green iguanas native to Marajó Island. The gastrointestinal system of four iguana specimens was evaluated for the presence of helminths. Altogether, 12,028 nematodes were found, with a prevalence of 100%, an infection range of 780 to 7,736 nematodes, an infection intensity of 3.007, and a mean abundance of 3,007. Light microscopy and scanning electron microscopy were used to determine the species of nematodes found. The cecum was the site of infection that had the highest parasitic load. Morphologically, the nematodes were compatible with the genus Ozolaimus Dujardin, 1844, with the species Ozolaimus megatyphlon (Rudolphi, 1819) Dujardin, 1845, and Ozolaimus cirratus Linstow, 1906. Scanning electron microscopy showed the presence of small structures (serrated in Ozolaimus cirratus and rounded in Ozolaimus megatyphlon) located below the esophageal leaves. We also evidenced the phasmids in both species; this is the first record of these structures in nematodes of the genus Ozolaimus. In addition, this work expands the records on the geographic distribution of these parasites.

Abstract The aim of this study was to determine the presence of deoxyribonucleic acid (DNA) from Toxoplasma gondii, Sarcocystis spp. and Neospora caninum, in tissues of wild boars slaughtered in southern Brazil. A total of 156 samples were collected from different organs of 25 wild boars, and DNA from at least one of the protozoa investigated was detected in 79 samples. To differentiate between infectious agents, restriction fragment length polymorphism was performed using the restriction enzymes DdeI and HpaII. For N. caninum, conventional PCR was performed with specific primers. The DNA of at least one of the studied pathogens was detected in each animal: 26.58% for T. gondii, 68.36% for Sarcocystis spp. and 5.06% for N. caninum. Coinfection between T. gondii and Sarcocystis spp. occurred in 14 animals, between T. gondii and N. caninum in only one male animal, between Sarcocystis spp. and N. caninum in a female, while co-infection with the three agents was equally observed in only one male animal. Considering the high frequency of detection and its zoonotic risk, especially T. gondii, it appears that wild boars can be potential sources of transmission of infectious agents and the adoption of monitoring measures in these populations should be prioritized.

Abstract The objectives of this work were to investigate the occurrence of parasites in feces of cats, compare different coproparasitological techniques for their diagnosis and determine associations with parasitism. The samples were processed using three different coproparasitological techniques: centrifugal flotation in sucrose, centrifugal flotation in ZnSO4 and simple sedimentation. The parasitic association between parasitism and variables such as age, sex and fecal consistency was performed using the chi-square test or the G test with a significance level of 5%. A total of 237 samples were analyzed, of which 93 (39.2%) were positive, being Ancylostoma spp. (17.3%), Giardia intestinalis (12.2%), Platynosomum illiciens (8.0%), Cystoisospora spp. (6.3%), Toxoplasma gondii/ Hammondia hammondi (3.4%), Diphyllobothriidae (2.1%), Toxocara spp. (1.7%), Dipylidium caninum (1.3%) and Mesocestoides spp. (0.8%). In the parasitism association analysis, it was possible to verify a statistical difference in the age category for Cystoisospora spp. (p=0.001) observing a strong relationship between parasitism and young animals, the association with sex proved to be important for P. illiciens (p<0.001) with a higher frequency of parasitized females and fecal consistency revealed to be related to the parasites G. intestinalis (p=0.007) and P. illiciens (p=0.033) showing a higher number of positive animals for these parasites with normal fecal consistency. In conclusion, we observed a higher occurrence of Ancylostoma spp. and G. intestinalis in fecal samples from domestic cats received in routine diagnoses and the presence of other parasites with zoonotic potential, as well as the relationship of these diagnosed parasites with the categories sex, age and fecal consistency.

Published: August 2023

The handheld drill has been used as a conventional surgical tool for centuries. Alongside the recent successes of surgical robots, the development of new and enhanced medical drills has improved surgeon ability without requiring the high cost and consuming setup times that plague medical robot systems. This work provides an overview of enhanced handheld surgical drill research focusing on systems that include some form of image guidance and do not require additional hardware that physically supports or guides drilling. Drilling is reviewed by main contribution divided into audio-, visual-, or hardware-enhanced drills. A vision for future work to enhance handheld drilling systems is also discussed.

Published: August 2023

Conserving the dwindling energy sources and preserving the environment are pertinent twain sustainable development issues in climes where renewable energy techniques have not matured. While the use of viable alternative sources of fuels has been identified as being able to minimize the occurrences of power outages caused by short supply and non-availability of the primary fuel for generating
electricity in the thermal power plants, the use of operating conditions which are favorable from both thermodynamic and environmental viewpoints is equally essential for the preservation of energy sources and the environment. In this work, air-fuel parametric studies on low-pour fuel oil (LPFO) as an alternative to natural gas in electricity generation were conducted based on environmental impacts. Typical emissions from a boiler designed to fire both fuels were simulated with HYSYS 8.8. The
potential environmental impacts (global warming, eutrophication, acidification, air smog, and human
health particulate) were simulated using GaBi. The outcomes of the studies show that an air-fuel ratio of 16.1 previously prescribed in earlier work from a thermodynamic viewpoint was not favorable to all the environmental indicators considered. A more informed decision on the choice of air-fuel ratio for fuel combustion can be achieved by developing a robust and encompassing pollution tax.

Published: August 2023

Mushrooms have two components, the fruiting body, which encompasses the stalk and the cap, and the mycelium, which supports the fruiting body underground. The part of the mushroom most commonly consumed is the fruiting body. Given that it is more time consuming to harvest the fruiting body versus simply the mycelia, we were interested in understanding the difference in metabolite content between the fruiting bodies and mycelia of four widely consumed mushrooms in Taiwan: Agrocybe cylindracea (AC), Coprinus comatus (CC), Hericium erinaceus (HE), and Hypsizygus marmoreus (HM). In total, we identified 54 polar metabolites using 1H NMR spectroscopy that included sugar alcohols, amino acids, organic acids, nucleosides and purine/pyrimidine derivatives, sugars, and others. Generally, the fruiting bodies of AC, CC, and HM contained higher amounts of essential amino acids than their corresponding mycelia. Among fruiting bodies, HE had the lowest essential amino acid content. Trehalose was the predominant carbohydrate in most samples except for the mycelia of AC, in which the major sugar was glucose. The amount of adenosine, uridine, and xanthine in the samples was similar, and was higher in fruiting bodies compared with mycelia, except for HM. The organic acid and sugar alcohol content between fruiting bodies and mycelia did not tend to be different. Although each mushroom had a unique metabolic profile, the metabolic profile of fruiting bodies and mycelia were most similar for CC and HE, suggesting that the mycelia of CC and HE may be good replacements for their corresponding fruiting bodies. Additionally, each mushroom species had a unique polar metabolite fingerprint, which could be utilized to identify adulteration.

Background: In the Postmenopausal phase, there is a drastic reduction in estrogen levels which may alter tendon metabolism and production of different growth factors, resulting in chronic tendon disorders or tendon rupture. Achilles tendinopathy predominantly affects athletes, but it may also impact individuals with sedentary lifestyles, especially women in their postmenopausal stage. We studied the effectiveness of eccentric exercise training on chronic Achilles tendinopathy in postmenopausal women. Methods: 31 females (aged 45-60, average age 51, BMI 27.6 ± 4.7, range 22.9- 32.3) in their postmenopausal phase with clinical diagnosis of chronic unilateral Achilles tendinopathy both insertional and mid-portion were assessed for pain and functional outcomes with VAS (on rest and on activity ) and VISA-A questionnaire before commencing the exercise and after completion of the training after a duration of 4 weeks. Results: Participants showed an acute improvement in pain on rest and activity and the VISA-A score post-intervention. There was no significant difference in the pre- and post-score on the VAS scale and the VISA- Questionnaire. The mean VAS scale score on rest was 3.580 pre-intervention and 2.903 post-intervention, while the VAS scale score (on activity) was 7.451 pre-intervention which reduced to 6.096 post-intervention. The mean VISA-A score pre-intervention was 39.80, and post-intervention was 46.35. Conclusion: Postmenopausal women suffering from chronic Achilles tendinopathy showed a significant result through training with an eccentric exercise program KEYWORDS: Achilles tendon, Postmenopausal women, Eccentric exercises.
Drink-Music: The ‘ól’ in Brian Ua Nualláin’s ‘!CEÓL!’ (1932)
Authors: LaBine Joseph , Harris Tobias W
Published: August 2023

In the illustration accompanying ‘!CEÓL!’ (!Music!), Brian Ua Nualláin’s 1932 Irish-language story about radio and gramophone music, Ua Nualláin uses an established but outdated spelling of ‘ceol’ to suggest a polysemantic pun. This pun is significant given the story’s subtitle – ‘Eachtra an Fhir Ólta’ (The Tale of the Drunkard) – because it places ‘ól,’ the Irish word for drink, inside the word for music, ‘ceol.’ The resulting portmanteau in Ua Nualláin’s illustration is interfusional in Thomas King’s sense, because it blends the textual with the oral. The orthography Ua Nualláin uses for his visual representation of ‘!CEÓL!’ draws attention to how the word is spoken, and the stress on the second half of the word makes it sound drunken. We argue that the story’s implied title, ‘Drink-Music,’ thematises intertextual play in ways that anticipate Ua Nualláin’s Middle Irish Joycean pastiche ‘Pisa bec oc Parnabus’ (1935/1938). This note provides the first critical discussion of the ‘!CEÓL!’ illustration, observing the presence of Ua Nualláin’s initials in the bottom right-hand corner of the image.

Yenilikçi çözüm için kanal giriş uzunluğu, kanat sayısı ve kanat türü parametrelerinin soğutma ve basınç kaybı üzerindeki etkisi Taguchi analizinde incelenmiştir. Kanal içi akış problemi sonuçları Comsol programında nümerik olarak gerçekleştirilmiştir. Maksimum ısı yayılımı ve basınç kaybı için en etkili parametrenin kanat sayısı (%83,11-%87,27) olduğu görülmüştür. Isı yayılımı açısından TRIZ analizi ile sonuç tasarımında, mevcut durumuna göre %6,6, basınç kaybı açısından %14,14 iyileşme gerçekleşmiştir. Ayrıca doğrulama çalışması için simülasyon ile Taguchi analizi sonuçları karşılaştırılmıştır. Sonuçların birbirine yakın olduğu tespit edilmiştir.

Bu çalışmada, harç ve örgü tipinin yığma duvarların mekanik parametrelerine olan etkisi araştırılmıştır. Buna bağlı olarak içeriğinde farklı karışım oranlarında çelik lif bulunan dört farklı harç tipi (%0, %1, %2 ve %3 oranında çelik lif içeren harç), üç farklı derz kalınlığı (10 mm, 20 mm ve 30 mm) ve üç farklı örgü tipi (düz, 1/2 şaşırtmalı ve 1/3 şaşırtmalı örgü tipleri) için toplamda 108 adet duvar elemanı oluşturulmuştur. Daha sonra ilgili duvar elemanları diyagonal basınç testine tabi tutulmuştur. Testler sonucunda, her bir duvar elemanının göçme biçimleri ve süneklik kapasitesi, maksimum kayma mukavemeti, maksimum yer değiştirme miktarı ve göçme yükü gibi mekanik parametreleri elde edilmiştir. Bu mekanik parametreler bakımından en iyi davranışı gösteren duvar elemanı (optimum duvar elemanı) belirlenmiştir.

Bu çalışmada zeminden gelen istenmeyen etkileri (yolculara iletilen titreşimi) ortadan kaldırmaya yönelik bir manyetik süspansiyon sisteminin tasarımı ve kontrolü amaçlandı. Tasarlanan manyetik süspansiyon sisteminde klasik süspansiyon sistemlerinden farklı olarak yay yerine mıknatıs kullanıldı. Mıknatısların manyetik kuvvetleri kullanılarak (itme ve çekme) titreşim kontrolü daha hassas bir şekilde gerçekleştirildi. Yürütülen bu çalışmanın özgünlüğü, zeminden gelebilecek her türlü farklı bozucu etkilere karşı manyetik alan etkisi altında doğal pasif mıknatıslarla çalışan bir süspansiyon tasarımını içermesidir. Bu sistemde kontrolcü bulunduğu konumu denge noktası kabul eder ve bu sayede zeminden gelen bozucu kuvvetlere rağmen döner mıknatısların açısını değiştirerek denge konumunda kalmaya çalışır. Böylece yolculara iletilen ivme değerleri geliştirilen manyetik titreşim kontrol sistemi sayesinde azaltılmıştır.
THE EFFECT OF FATTY LIVER DISEASE ON PORTAL VEIN FLOW IN OBESE ADOLESCENTS

Objective

The increase in obesity in children has caused

nonalcoholic fatty liver disease to become the most

important chronic liver disease in the pediatric age

group. In this study, we aimed to evaluate the portal

diameter and blood flow velocity in obese children with

fatty liver (NAFLD) and to compare them with normal

healthy children.

Material and Method

71 obese adolescent patients aged 10-18 years were

divided into two groups (NAFLD group and non-

NAFLD group) according to the presence of elevated

transaminases and the presence of hepatosteatosis

on ultrasound. 30 healthy adolescents were included

in the study as the control group. Blood samples

were taken from each patient for fasting glucose,

insulin, transaminases, and thyroid functions. Insulin

resistance was calculated using the HOMA index.

Portal vein measurements were performed from the

main portal vein before bifurcation.

Results

The portal vein diameter (8.5 ± 0.9 mm) of the NAFLD

group was statistically significantly wide compared

to both the control group (7.8 ± 2.0 mm) and the

non-NAFLD obese group (7.6 ± 1.1 mm) (p= 0.004)

and (p= 0.002). There was no significant difference

between the non-NAFLD obese group and the control

group (p=0.460, p=0.214). There was no significant

difference between the groups in terms of portal vein

Vmax, Vmin, RI, S/D. Although there was no difference

in portal vein diameter in the obese groups classified

according to insulin resistance, Vmax (33.9 ± 10.3 and

28.6 ± 10.6 cm/sec, p= 0.03) and Vmin (24.8 ± 6.2 and

20.5 ± 5.5 cm/sec) were significantly different in the

insulin resistance group.

Conclusion

In this study, it was determined that portal vein diameter

and flow velocities (Vmax and Vmin) increased in

obese adolescents with NAFLD. Thus, we suggest

that resistance develops in hepatic venous flow due

to hepatic portal vein steatosis, especially in obese

patients with insulin resistance in adolescence. This

finding suggests that when fatty liver continues, portal

diameter will increase in adulthood, leading to portal

hypertension.

The Seahorse XFp Extracellular Flux Analyzer is designed to compare two different cultures or treatments. Culture cells as usual in either cell culture dishes or flasks as preferred. It is best to compare two cultures of a similar passage number, cell density, time that the cells have been in culture and time since the medium was changed as all this influences mitochondrial respiration. Culture cells until they are almost/just confluent. Cell should have been fed recently before use.

Published: August 2023

The purpose of the study. Demonstration of differential diagnostic search for the causes of acute kidney injury (AKI) in a young man.

Materials and methods. Clinical observation of a patient with Takayasu arteritis (TAK).

Results. The presented clinical observation describes the late diagnosis of TAK at the stage of severe ischemic lesions of the internal organs (myocardial infarction, cerebral infarction, occlusion of the lumen of the arteries of the left lower limb with the development of gangrene, occlusion of the renal arteries with the outcome of left kidney shrive­ling). Most likely, thrombotic occlusion of the right renal arteries caused the development of severe AKI. During the examination, the diagnosis of TAK was made, other possible nosologies were excluded. Taking into account the late diagnosis of the disease, the minimal severity of the inflammatory process, the high risk of complications, therapy with glucocorticoids in a small dose, anticoagulants was carried out. Against this background, recovery of intrarenal blood flow and diuresis was noted, but high rates of azotemia remained, requiring continued dialysis. After 3 months, the loss of renal functions was detected.

Conclusions. The development of vascular lesions of internal organs with signs of critical ischemia (heart, brain, vessels of the lower extremities, kidneys, etc.) in young patients, dictates the need for a differential diagnostic search for the cause, first of all, the exclusion of the systemic process (systemic vasculitis, antiphospholipid syndrome, diffuse con­nective tissue diseases). It is important to accumulate experience in managing patients with TAK in order to timely diagnose, start therapy early and prevent the development of irreversible lesions of internal organs.
Acute rheumatic fever and rheumatic heart disease: what's new?

Published: August 2023

Rheumatic heart disease (RHD) is a preventable heart disease that remains endemic in developing countries. More than 30 million people in the world suffer from RHD, of which approximately 300,000 die every year, despite the fact that this disease is preventable and treatable. After a period of relative neglect of rheumatic heart diseases due to a decrease in the incidence in developed countries, interest in this problem has increased again over the past decade, due, apparent­ly, to an underestimation of its true prevalence due to the subclinical course of carditis. Research over the past two decades has demonstrated the advantage of diagnosing RHD with echocardiographic screening based on World Heart Federation echocardiographic criteria, which is 10 times greater than the clinical auscultatory picture only and it allowsearly detection of it in patients, while prevention is to be more likely to be effective. Although understanding of the pathogenesis of the disease has advanced in recent years, key issues remain unresolved. Preventing or providing early treatment for streptococcal infections is the most important step in reducing the burden of this disease. The manage­ment of women with rheumatic heart disease before, during and after pregnancy remains a serious task requiring the efforts of a multidisciplinary team. In 2015, a civil society movement was launched aimed at raising awareness and supporting countries seeking to solve the RHD problem. In May 2018, the World Health Organization adopted a resolu­tion aimed at intensifying global and national efforts to prevent and combat acute rheumatic fever/RHD. Ultimately, a combination of treatment options, research and advocacy based on existing knowledge and science provides the best opportunity to cope with the burden of rheumatic heart disease. The article summarizes the latest achievements in the science of RHD and presents priorities for current actions and future research.

Published: August 2023

The article examines the association of aphids along with their food plants, parasitoids and predators in varying ecological conditions for the possible use in biological control programs. Aphids are small, sap-sucking insects and they are considered an important pest of agricultural and horticultural plants due to sucking of vital nutrients and transmitting viral diseases. During the survey, 41 species of aphids were recorded on 122 plant species in northeast Bihar. Three species of Myzus viz., M. ascalonicus, M. persicae and M. variants were recorded.  M. persicae was recorded on 36 food plants from December to April but its peak population was observed during February and March. Five species of parasitoids (Aphelinus albipodus, Aphelinus gossypii, Aphidius colemani, Binodoxys indicus, Diaeretiella rapae, Lipolexis oregmae), five species of coccinellid predators (Cheilomenes sexmaculata, Coccinella septempunctata, Coccinella transversalis, Micraspis discolor, Scymnus pyrocheilus) and three species of syrphid predators (Dideopsis aegrota, Ischiodon scutellaris, Melanostoma orientale) were recorded on M. persicae. Among these, three parasitoids (B. indicus, L. oregmae, A. gossypii), four coccinellids predators (C. sexmaculata, C. septempunctata, C. transversalis, S. pyrocheilus) and two syrphid predators (D. aegrota, I. scutellaris) were observed abundantly in all localities with a high rate of parasitization/predation on M. persicae.
