RESUMEN

Cagarras Islands Archipelago, a no-take MPA in Southeast Brazil, was designated as Natural Monument (MONA Cagarras) and, more recently, recognized as Hope Spot for biodiversity conservation. This study aimed to assess plastic contamination by analyzing marine litter and microplastics in MONA Cagarras and surrounding waters. Marine litter (34.12 kg) was caught by artisanal fishermen in MONA Cagarras proximities, and plastics represented ∼79 %. Personal hygiene items and strains of hair were found, suggesting sewage-derived contamination from Ipanema SSO. Microplastics were detected in MONA Cagarras surface waters. Fragments and black particle were the most frequently found microplastic shape and color, respectively. µ-FTIR analysis identified, in descending order of occurrence, polystyrene-PS, polyethylene-PE, polyvinyl chloride-PVC, polypropylene-P, and polyamide-PA. Our integrated results of macro and microplastic contamination highlight an issue of effective conservation and health of marine biodiversity in MONA Cagarras and surrounding waters and a concern for better management of Brazilian MPAs.

RESUMEN

ABSTRACT Purpose: This study investigates the protective effect of cilostazol on the development and evolution of diabetic retinopathy in rats. Methods: Sixty male rats were divided into four groups: untreated nondiabetic rats, untreated diabetic rats, cilostazol-treated nondiabetic rats, and cilostazol-treated diabetic rats. The thickness of the internal limiting membrane to the outer limiting membrane, inner plexiform layer, inner nuclear layer, and outer nuclear layer were measured. The number of cell nuclei per 50-μm length in retinal sections was counted to quantify the degree of retinal cell loss. Results: The number of nuclei in the ganglion cell layer was significantly higher in untreated nondiabetic rats (p<0.05). The mean number of nuclei in the cilostazol-treated nondiabetic rats was significantly higher than that in the cilostazol-treated diabetic rats (p<0.05). The cilostazol-treated nondiabetic rats had a significantly higher mean nuclei count in the inner nuclear layer and inner plexiform layer as compared with the other groups (p<0.05). The total mean retinal thickness of the cilostazol-treated nondiabetic rats was significantly higher than that of cilostazol-treated diabetic rats and untreated diabetic rats (p<0.05). Conclusion: By decreasing the loss of ganglion cells and reducing the sensorineural atrophy in the internal retinal layers, cilostazol had a protective effect against changes caused by diabetic retinopathy in diabetic rats.

RESUMO Objetivo: O objetivo deste estudo foi investigar o efeito protetor do cilostazol no desenvolvimento e na evolução da retinopatia diabética em ratos. Métodos: Sessenta ratos machos foram divididos em 4 grupos: ratos não-diabéticos não-tratados, ratos diabéticos não-tratados, ratos não-diabéticos tratados com cilostazol e ratos diabéticos tratados com cilostazol. A espessura da membrana limitante interna à membrana limitante externa, a camada plexiforme interna, a camada nuclear interna e a camada nuclear externa foram medidas. Para quantificar o grau de perda de células da retina, foi contado o número de núcleos de células por 50 μm de comprimento em secções retinianas. Resultados: O número de núcleos no GCL foi significativamente maior em Ratos não-diabéticos não-tratados com cilostazol (p<0,05). O número médio de núcleos em Ratos não-diabéticos tratados com cilostazol foi significativamente maior do que em Ratos diabéticos tratados com cilostazol (p<0,05). A contagem média de núcleos em camada nuclear interna e camada plexiforme interna de ratos não-diabéticos tratados com cilostazol foi significativamente maior do que nos outros grupos (p<0,05). A espessura retiniana média total de Ratos não-diabéticos tratados com cilostazol foi significativamente maior do que em Ratos diabéticos tratados com cilostazol e Ratos diabéticos não-tratados (p<0,05). Conclusão: Os resultados demonstraram que o cilostazol teve um efeito protetor contra as alterações causadas pela retinopatia diabética em ratos diabéticos, diminuindo a perda de células ganglionares e reduzindo a atrofia neurossensorial nas camadas retinianas internas.

RESUMEN

OBJECTIVE: Areas of the foot with diabetic ulcers have been observed to have greater plantar pressures compared to non-ulcerated. Pressures play an essential role in the mechanism of lesion, and their reduction is effective in prevention. We conducted a systematic review to evaluate pedobarography as a predictive tool for ulcer development, since there is still no consensus on this aspect. METHODS: We searched PUBMED (MedLine), EMBASE, Scopus, Web of Science, CINAHL and Scielo for cohort studies that measured plantar pressure at baseline and verified ulcer development on follow-up. Pooled effects of accuracy, sensitivity, specificity and relative risk were calculated using the inverse variance method. Risk of bias was assessed using the QUADAS-2 tool. RESULTS: Three studies (n = 2000) had enough information on accuracy to be included into a meta-analysis, and 4 (n = 2651) were analyzed using qualitative methods. Pooled sensitivity and specificity were found to be 0.63 (Confidence Interval (CI) 0.58-0.68) and 0.42 (CI 0.27-0.58), respectively. Pooled relative risk was 1.95 (CI 1.09-3.51). Risk of bias was low to uncertain. CONCLUSIONS: Pedobarography in itself appears to have low accuracy in evaluating risk of ulceration. Several methodological heterogeneities were found, and the most optimal cut-off value is yet to be determined.

RESUMEN

A retrospective cohort study of hospital-acquired pressure injuries (HAPI) reported an incidence rate of 34.3% based on 582 medical records of adult patients admitted to the intensive care unit (ICU) of a medium-complexity public hospital in 2017 and 2018. Sixty percent of the patients used respirators, 49.3% presented hypotension, and 48.1% used norepinephrine. The main individual predictors of HAPI in the ICU were "days of norepinephrine" with an odds ratio (OR) of 1.625 (95% CI: 1.473-1.792) and concordance statistic (AUC) of 0.818 (95% CI: 0.779-0.857), "days of mechanical ventilation" with an OR of 1.521 (1.416-1.634) and AUC of 0.879 (0.849-0.909), "ICU stay (days)" with an OR of 1.279 (1.218-1.342) and AUC of 0.846 (0.812-0.881), and "Braden's sensory perception" with an OR of 0.345 (95% CI: 0.278-0.429) and AUC of 0.760 (0.722-0.799). The duration of mechanical ventilation, norepinephrine administration, and ICU length of stay presented significant discriminative capacity for HAPI prediction.

RESUMEN

O objetivo deste estudo foi compreender a inserção e a atuação do profissional de Educação Física no NASF em Santos-SP. Trata-se de uma pesquisa de abordagem qualitativa, na qual participaram 3 profissionais de Educação Física. A coleta de dados se deu por entrevista semiestruturada, e os dados foram interpretados à luz da análise de conteúdo. Como resultado, compreende-se que a inserção dos profissionais no NASF é inerente ao cargo ocupado. A atuação se dá num cenário limitante em número de profissionais e legitimação, trabalho anterior isolado e uma prática pedagógica instrumental, entretanto, aberta aos ideários críticos. Assim, embora haja um potencial alinhamento da atuação em relação às diretrizes do NASF, conclui-se que ainda existem limites a superar (AU)

The aim was to comprehend the insertion and performance of the Physical Education professional in the Family Health Support Centers (NASF) in the city of Santos-SP. It is a qualitative research in which three Physical Education professionals participated as volunteers. For this, semi-structured interviews were carried out and the data were analyzed through content analysis. As a result, the insertion of these professionals in the NASF is inherent to the position held. The performance is developed in a limiting context in terms of number of professionals and legitimacy, previous separate work, and an instrumental pedagogical practice; however, it opens to critical framework. Although the performance is potentially aligned with the NASF, we concluded there are limits to surpass yet (AU).

RESUMEN

BACKGROUND: Chronic venous insufficiency (CVI) is a common disease that causes calf muscle pump dysfunction and has repercussions for the hemodynamics of the structures involved. OBJECTIVES: To analyze the effects on venous hemodynamics of exercises to strengthen the calf muscles in patients with CVI. METHODS: The study analyzed 25 lower limbs with CVI, classified from C1 to C5 according to the Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) classification, in 13 patients recruited from a Lymphedema and Angiodysplasia Clinic at the Hospital Universitário Regional dos Campos Gerais (Brazil). The variables analyzed were collected by isometric dynamometry, goniometry, leg circumference measurement, and adipometry at baseline, after 1 month and 2 months and at the end of the exercise protocol. RESULTS: Dorsiflexion and plantar flexion measurements increased by 5º (p < 0.001). Adipometry detected a reduction in 5 mm (p < 0.001). When grouped by CEAP class, C2 exhibited 5º increases in dorsiflexion (p = 0.02) and plantar flexion (p < 0.001); C3 exhibited a 5ºincrease in dorsiflexion (p = 0.003) and a 1mm reduction in adipometry (p < 0.004); and C1 exhibited a 1.2cm increase in leg circumference (p = 0.04). CONCLUSIONS: Administration of exercise protocols should be considered as a treatment option for CVI, since it has a positive impact on risk factors and on the functions that are impaired by this pathology.

RESUMEN

OBJETIVO: Avaliar a influência das palmilhas customizadas na pressão plantar de diabéticos com neuropatia em comparação ao grupo sham. MÉTODOS: O método do estudo, devidamente registrado no Registro Brasileiro de Ensaios Clínicos ­ REBEC (Clinical Trial Brazilian Register) (http://www.ensaiosclinicos.gov.br/) RBR-5NQK4K, incluiu um ensaio clínico randomizado, controlado, prospectivo, duplo-cego, com uma amostra de 46 voluntários que serão randomizados aleatoriamente numa razão de 1: 1 para serem direcionados aos grupos intervenção e controle. O grupo intervenção receberá palmilhas customizadas, com barra retrocapital e placa de etil vinil acetato (EVA) no mesmo formato da barra retrocapital, com a finalidade de reduzir a pressão no antepé. No grupo controle, as palmilhas planas serão confeccionadas sem nenhum objetivo terapêutico. Este projeto foi conduzido de acordo com o padrão de protocolo para ensaios clínicos randomizados (SPIRIT). Junto com a avaliação clínica, serão coletados dados demográficos da amostra para identificar e confirmar a presença de neuropatia periférica, em seguida, será avaliada a podobarografia e, por fim, os pacientes responderão ao questionário FAAM para avaliação da funcionalidade do pé. O desfecho primário será a análise dos pontos de pressão em KiloPascal (kPa) no pé dos pacientes com neuropatia diabética por meio da podobarografia nos pacientes do grupo intervenção e controle. O desfecho secundário será a funcionalidade do pé nas atividades de vida diária através do questionário FAAM (Foot and Ankle Ability Measure), considerando os voluntários na avaliação inicial, 3º e 6º meses. CONSIDERAÇÕES FINAIS: os futuros resultados deste estudo nos mostrarão principalmente se há ou não uma alteração estrutural na análise da pressão plantar decorrente do uso contínuo da palmilha, além de avaliar se o uso da palmilha terapêutica é eficaz na funcionalidade do pé nos mesmos portadores quando comparado à palmilha sham.

| OBJECTIVE: To evaluate the influence of customized insoles in the plantar pressure of diabetes patients with neuropathy in comparison to the sham group. METHODS: The work method, duly registered at the Registro Brasileiro de Ensaios Clínicos ­ REBEC (Clinical Trial Brazilian Register) (http://www.ensaiosclinicos.gov.br/) RBR-5NQK4K, includes a randomized, controlled, prospective, doubleblinded clinical trial, with a sample of 46 volunteers that will be randomly randomized in a 1: 1 ratio to be referred to intervention and control groups. The intervention group will receive customized insoles, with a retrocapital bar and an ethyl vinyl acetate plaque (EVA) in the same shape as the retrocapital bar, in order to reduce the pressure on the forefoot. In the control group, flat insoles will be prepared without any therapeutic objective. This project was developed according to the standard protocol for randomized clinical trials (SPIRIT). Along with the clinical evaluation, demographic data of the sample will be collected to identify and confirm the presence of peripheral neuropathy, next, the pedobarographic will be evaluated, and finally, the patients will answer the FAAM questionnaire to assess foot functionality. The primary outcome will be analyzing pressure points in KiloPascal (kPa) in the patients' feet through pedobarographic of the patients in the intervention and control groups. The secondary outcome will be the foot functionality in activities of daily living through the FAAM (Foot and Ankle Ability Measure), considering the volunteers in the initial evaluation, third and sixth months. FINAL CONSIDERATIONS: Mainly, results of this study will show whether there is a structural alteration in the analysis of the plantar pressure due to the continuous use of insoles and present the evaluation of whether the use of therapeutic insoles improves the foot functionality of the same users when compared to sham insoles.

RESUMEN

This study comprises the first record of a juvenile Giant Devil Ray specimen for Rio de Janeiro, Southeastern Brazil, and its metal and metalloid contents. A scientometric assessment was also performed for the Manta and Mobula genera. Only five records were found, and only As, Cd, Pb, Hg, Pt, Pd and Rh have been assessed. All studies but one concerned human consumption. A significant knowledge gap on metal and metalloid ecotoxicology for mobulid rays is noted, indicating the emergence of a new field of research that th may be applied for wildlife conservation and management in response to anthropogenic contamination. Our study is also the first to provide Al, Cr, Cu, Fe, Mn, Sr, Ti, V and Zn contents for muscle, liver, brain and kidney for a mobulid ray and one of the scarce reports concerning As, Cd, Hg and Pb in muscle, liver and kidney.

RESUMEN

Our aim was to analyze and compare the effects of three different long-term treatments on anthropometric profiles, eating behaviors, anxiety and depression levels, and quality of life of groups of adults with obesity. Methods: The 43 participants in the study were randomly assigned to one of three groups: the education and health group (EH, n = 12), which received lectures on health topics; the physical exercise group (PE, n = 13), which underwent physical training; and the interdisciplinary therapy plus cognitive behavioral therapy (IT + CBT) (n = 18) group, which received physical training, nutritional advice, and physical and psychological therapy. Results: Total quality of life increased significantly in the EH group (△ = 2.00); in the PE group, body weight significantly decreased (△ = -1.42) and the physical domain of quality of life improved (△ = 1.05). However, the most significant changes were seen in the IT + CBT group, in which the anthropometric profile improved; there were an increase in quality of life in all domains (physical, psychological, social, and environmental), an improvement in eating behaviors [Dutch Eating Behavior Questionnaire (DEBQ), total △ = -8.39], and a reduction in depression [Beck Depression Inventory (BDI), △ = -10.13). Conclusion: The IT + CBT program was more effective than the PE and EH programs. Clinical Trial Registration Number: NCT02573688.

RESUMEN

Resumo Contexto A insuficiência venosa crônica (IVC) é uma doença comum, uma disfunção da bomba muscular da panturrilha que repercute na hemodinâmica das estruturas. Objetivos Analisar os efeitos dos exercícios de fortalecimento muscular da panturrilha na hemodinâmica venosa em pacientes com IVC. Métodos O estudo contou com a participação de 13 pacientes e 25 membros inferiores com IVC, classificados entre C1 e C5 da classificação Clínica, Etiologia, Anatomia e Fisiopatologia (CEAP), oriundos do ambulatório de cirurgia vascular do Hospital Universitário Regional dos Campos Gerais. As variáveis analisadas foram dinamometria isométrica, goniometria, perimetria, adipometria no início, primeiro mês, segundo mês e final da aplicação do protocolo de exercícios. Resultados Os valores da dorsiflexão e da plantiflexão aumentaram 5º (p < 0,001). Na adipometria notou-se uma redução de 5 mm (p < 0,001). Quando separados em grupos pela CEAP, na C2 houve aumento de 5º na dorsiflexão (p = 0,02) e na plantiflexão (p < 0,001); na C3 houve aumento de 5º na dorsiflexão (p = 0,003) e redução de 1 mm na adipometria (p < 0,004); na C1 houve aumento da perimetria de 1,2 cm (p = 0,04). Conclusões A aplicação de protocolos de exercícios deveria ser considerada como uma forma de tratamento para IVC, pois impacta positivamente em fatores de risco e nas funções que estão deterioradas pela patologia.

Conclusions Administration of exercise protocols should be considered as a treatment option for CVI, since it has a positive impact on risk factors and on the functions that are impaired by this pathology.

RESUMEN

The objective of this study was to evaluate the feeding and agonistic behavior of Quarter Horses kept in different types of stalls in the semiarid region of Minas Gerais. A completely randomized design with two treatments (two types of stalls) and seven replicates (seven days of evaluation) was used. Four Quarter Horse mares and four stallions were used per treatment. Behavioral observations were made at 10-minute intervals for 24 hours. The stall environment was characterized by the following variables: air temperature, relative humidity, and black globe temperature for subsequent estimation of the wet-bulb globe temperature. Feeding behavior variables included: time spent eating concentrate and time spent eating roughage (hours), bite rate (bites/min), and the number of daily bites (bites/day). Zinc-roofed stalls had higher air temperatures than clay-roofed stalls and the external environment, averaging 28.2, 27.0, and 27.4 ºC, respectively, while relative humidity was significantly lower in the external environment (65.80%). Horses housed in zinc-roofed stalls had longer feeding times (8.32 h) than animals kept in clay-roofed stalls (7.22 h). Approximately 94% of the total feeding time was spent eating roughage and 73% of the time was spent resting and walking, regardless of the covering type. Although environmental variables showed thermal discomfort, the roofing material did not alter the feeding behavior of stabled horses in the semiarid region of Minas Gerais, suggesting an adaptation to the studied conditions. The feeding frequency should be increased to avoid a long resting time.(AU)
