The results of SMT, osmolarity, TFT, SDS-PAGE, and tear biochemistry may serve as a reference baseline for CM, and the data may serve as a basis for future experimental model evaluations.

This study aimed to assess the birefringent properties of corneal stromal collagen fibrils in birds of the orders Falconiformes (diurnal) and Strigiformes (predominantly nocturnal) to compare their supramolecular organizations. Twenty-two corneas of Falconiformes (Caracara plancus, n = 8; Rupornis magnirostris, n = 10; and Falco sparverius, n = 4) and 28 of Strigiformes (Tyto furcata, n = 16; Pseudoscops clamator, n = 6; and Athene cunicularia, n = 6) were processed histotechnically into 8 μm thick sections. Corneal optical retardation values related to the form and intrinsic fractions of the total birefringence of collagen fibrils were measured using a polarized light microscope equipped with phase compensators. In addition, the coherence coefficients that inform the local orientation of the fibrils were calculated through video image analysis. All assessments were conducted both in the anterior and posterior stroma of the cornea. Differences were significant when p < 0.05. The results showed supraorganizational differences between fibrils in the anterior stroma of Falconiformes and Strigiformes. The optical retardation values were greater (p < 0.0001) for Falconiformes, indicating that the corneas of these birds contain more collagen fibrils or more aggregated collagen fibrils. In contrast, the coherence coefficients were higher (p = 0.016) for Strigiformes, indicating that the collagen fibers in these birds are highly aligned and have few undulations. A multivariate data matrix constructed for Euclidean distance calculations showed that the dissimilarity between Falconiformes and Strigiformes corneas, in terms of the supraorganization of stromal collagen fibrils, was 4.56%. In conclusion, it is possible that the supraorganizational differences reported in this study may be sources of variation in the visual quality of Falconiformes and Strigiformes. This study provides the necessary evidence to encourage further research associating corneal optical performance to supramolecular characteristics of corneal stromal collagen.

These results, showing differences in the conjunctival bacterial flora of free-living and captive animals, may be helpful for diagnosis and treatment of ocular disorders in sea turtles.

This article aims to describe a case report of an immunocompetent adult patient with rotavirus infection, highlighting the points to be reviewed and the conducts performed, in order to include in the routine of health professionals more appropriate actions in cases of diarrhea. acute. The research was conducted qualitatively, with the direct collection of patient data, describing the events chronologically, aiming at a better understanding of the clinical picture and medical actions. The patient presented with diarrhea and colic, with worsening in 24 hours, being seen at the emergency room and later with specialist in infectology. Routine examinations, water and food support were performed during hospitalization, as well as symptomatic therapy and antibiotic therapy. Complementary examinations showed fecal rotavirus positivity, anti-HIV 1 - 2 negatives, co-culture and negative Clostridium difficile screening, and presence of liquid cecum-ascending dilation on computed tomography. During the evaluation period, a deficit in conduct points and decision-making concerns was visualized in patients with acute diarrheal diseases in a hospital environment. Thus, it is concluded that some protocols performed in ADD patients, such as the use of antibiotic therapy, should be closely monitored, as well as the need for greater attention to biosecurity and, consequently, the risk of new infections in the environment. in addition to the need for data to accompany the occurrence of rotavirus in adult patients, which target not only public units, which may serve to leverage preventive methodologies.

Objetivo: Analisar e descrever através de uma revisão sobre quais são os possíveis impactos, metodologias de prevenção e soluções dentro dos parâmetros pandêmicos da Covid-19, de uma maneira clara e destinada ao público, com intuito de promover conscientização e ampliar o conhecimento. Revisão bibliográfica: A pesquisa foi realizada de forma exploratória e qualitativa no contexto dos acontecimentos atuais, e nas opiniões científicas encontradas na atualidade sobre dados epidemiológicos do COVID-19. Demonstrou-se o aumento nocivo da doença de forma descontrolada e seus reflexos recorrentes devido à falta efetiva de uma incursão educacional, legislativa e nutricional. O despreparo em enfrentar e prevenir as mazelas da sociedade ocasionadas pela fácil transmissão e propagação de doenças infecto-agressivas, e sua abrangência nos vários setores da sociedade brasileira. Notou-se também que manobras emergenciais esbarraram nos entraves burocráticos. Considerações finais: Após a consecução da pesquisa houve um vislumbre ainda das falhas governamentais e da própria população frente as suas possíveis ações para evitar e combater casos excepcionais de perigo iminente.

Health professionals are commonly exposed to risks associated with their craft; however, although their health is guaranteed by the Organic Health Law, there are several times if inappropriate, inefficient or neglected biosafety behaviors are observed. This article aimed to evaluate the facilities and working conditions of employees in a emergency unit, to identify the main occupational risks and to assist the perception of the competent bodies in the identification and reduction of risks of health promoting institutions. Through forms prepared from NR 32, the 112 employees of a emergency unit in the state of São Paulo were evaluated. The study was conducted with 82/112 (73.21%) of employees, with the distribution of positions among nursing technicians (70.7%), nurses (14.6%), and x-ray technicians (6, 1%) pharmacy technicians (4.9) and radiologists (3.7%). Structural disabilities in some sectors were identified during the evaluation, physical constraints compared to the number of attendances, restrictions on material collection and structural maintenance planning, as well as lack of staff preparation for some functions such as the use of fire extinguishers, or negligence regarding the use of personal protective equipment and deficiencies in sanitary protocols. Biosafety actions can prevent and reduce the risks associated with their craft, while also ensuring population and environmental health. This study can serve to guide projects and institutional protocols, with the purpose of reducing risks inherent to professionals and patients of health facilities.

Background Environmental changes contribute to the development of ophthalmic diseases in sea turtles, but information on their eye biometrics is scarce. The aim of this study was to describe ophthalmic ultrasonographic features of four different sea turtle species; Caretta caretta (Loggerhead turtle; n = 10), Chelonia mydas (Green turtle; n = 8), Eretmochelys imbricata (Hawksbill turtle; n = 8) and Lepidochelys olivacea (Olive ridley; n = 6) under human care. Corneal thickness, scleral ossicle width and thickness, anterior chamber depth, axial length of the lens, vitreous chamber depth and axial globe length were measured by B-mode sonography with a linear transducer. Carapace size and animal weight were recorded. A sonographic description of the eye structures was established. Results The four species presented an ovate eyeball, a relatively thin cornea, and a small-sized lens positioned rostrally in the eye bulb, near the cornea, resulting in a shallow anterior chamber. The scleral ossicles did not prevent the evaluation of intraocular structures, even with a rotated eye or closed eyelids; image formation beyond the ossicles and measurements of all proposed structures were possible. B-mode sonography was easily performed in all animals studied. The sonographic characteristics of the eye were similar among the four species. Since there was a correlation between the size of the eye structures and the size of the individual, especially its carapace size, the differences found between E. imbricata and Caretta caretta are believed to be due to their overall difference in size. Conclusions Sonography is a valuable tool in ophthalmic evaluation of these species. Only minor differences were found between the species in this study, reinforcing their phylogenetic proximity and their similar functions and habitats.
