RESUMO

Infections caused by Candida spp. are frequent in critically hospitalized patients, especially among premature neonates, representing one of the most common healthcare-related infections. Although there is considerable production of current knowledge about the mechanisms of immune response, aspects involved in the newborn's innate defense are not fully understood. The aim of this study was to describe the innate immune mechanisms involved in the defense of neonates against invasive candidiasis. This is an integrative literature review from the Scopus, Scifinder, Medline, Web of Science databases and the electronic libraries ScienceDirect and Scielo, in the period between 2002 and 2020, with rescue based on primary descriptor Immunity Innate plus secondary descriptors Candidiasis Invasive AND Infant Newborn. We have observed the involvement of various mechanisms in the neonatal response against invasive candidiasis, including the recognition, signaling, recruitment, and initiation of an effective immune response. These mechanisms encompass the presence of antimicrobial peptides, phagocytosis, synthesis of reactive oxygen species, inflammatory mediators, and complex cell signaling systems mediated by Pattern Recognition Receptors (PRRs). With this study, it is expected to contribute to the expansion of knowledge about the immunological mechanisms involved in the innate immune response of the newborn against disseminated infections caused by Candida species, and in the same sense, highlight the importance of this knowledge as a reflex in the decrease in mortality in the neonatal period.

RESUMO

The presence of fungi in healthcare settings, including hemodialysis units, represents a significant risk for immunocompromised patients. This study aimed to investigate the occurrence of fungi in the air and water of a hemodialysis unit located in a tertiary public hospital in Maceió, Alagoas, Brazil. Over a period of three consecutive months, monthly air samples were collected and analyzed using the spontaneous sedimentation technique on Petri dishes containing Sabouraud Dextrose Agar (SDA). Simultaneously, water samples (100 mL) were collected from four specific water distribution points and subjected plating on SDA. Fungi were phenotypically identified based on their macroscopic and microscopic characteristics. In total, 498 colony-forming units (CFUs) of fungi were isolated, with 86 CFUs originating from the air and 412 CFUs from the water. Regarding the water samples, a higher concentration of fungal CFUs was observed in the potable water from the supply network (229 CFUs). Unexpectedly, 23 CFUs were identified in the reverse osmosis samples and 11 CFUs in the storage tank, which are post-treatment points where the presence of microorganisms is not desired. The fungus Cladosporium spp. was the most prevalent in both air and water samples, followed by Penicillium spp. in the air and Rhodotorula spp. in the water. These findings underscore the need to implement effective control and monitoring measures for fungi in the hemodialysis unit to ensure patient safety.

RESUMO

The aim was to evaluate smoked blood sausage prepared using goat blood (50%), viscera (10%) and meat fragments (20%). Microbiological, chemical and sensory evaluations were conducted. The quality analyses showed that smoked goat blood sausage is rich in high biological value proteins, amino acids, essential fatty acids, and iron (26.65mg/100g). The smoked goat blood sausage was rated to have a sensory acceptance of greater than 80%. The use of edible by-products from the slaughter of goats in the formulation of smoked blood sausage is viable because it uses low-cost raw materials; furthermore, the utilisation of these by-products can generate income for producers, allowing them to offer a meat product of high nutritional and sensory quality.

RESUMO

The objective of this work was to study the morphology and biometry of the infraorbital foramen (FIO), variations in its shape, size and number as well as to obtain measurements of its location. 60 dry skulls were analyzed. The test of Qui-quadrant and the T Test were used in measurements with a 5 percent significance. On the right side, the FIO was measured at a distance of 6.49(+/-1.68) mm from the lower, 39.65(±3) mm from the upper, 17.7(+/-2.97) mm from the medial and 20.46(+/-2.9) mm from the lateral margin of the orbit; its pear-shaped opening distance was 13.67(+/-2.17) mm. On the left side, the distance of the FIO to the lower margin of the orbit was 6.52(+/-1.82) mm; to the upper margin was 39.9(+/-2.62) mm and to the lateral and medial margin were 17.93(+/-2.58) mm and 21.12(+/-3) mm, respectively; its distance to the pear-shaped opening was 14.26(+/-1.83) mm. It was found predominately in an oval shape, in 39 (65 percent) of the skulls, on both sides. Accessory foramens were present in 11 samples on the right and in 15 samples on the left side. The FIO was most frequently found on the side of, or laterally to the sagittal plane that passes through the middle of the supraorbital foramen/ incisures, in 38 skulls (63.3 percent) on the right side and in 45 skulls (75 percent) on the left and middle to the zigomatic-maxillary suture, in 41 skulls (68.3 percent) on right and in 42 skulls (70 percent) on the left side, besides being most frequently found in a region between the first and second premolars, in 22 skulls (36.7 percent) on the right side and in 17 skulls (28.3 percent) on the left...

La distancia de apertura fue 13,67 (+/- 2,17) mm.En el lado izquierdo, la distancia del FIO al margen inferior de la órbita fue 6,52 (+/- 1,82) mm; al margen superior fue 39,9 (+/- 2,62) mm y a los márgenes lateral y medial fue 17,93 (+/- 2,58) mmy 21,12 (+/- 3) mm, respectivamente. La distancia a la abertura piriforme fue 14,26 (+/- 1,83) mm. Su forma era predominantemente ovalada, en 39 (65 por ciento) de los cráneos. Forámenes accesorios estaban presentes en 11 muestras en el lado derechoy en 15 muestras en el lado izquierdo.El FIO estaba localizado más frecuentemente lateral al plano sagital que pasa por el centro del foramen supraorbital. De estos casos, en 38 cráneos (63,3 por ciento) en el lado derecho y en 45 cráneos (75 por ciento) en el lado izquierdo.Los FIO estaban en el punto medio de la sutura cigomática-maxilar en 41 cráneos (68,3 por ciento) en el lado derecho y en 42 cráneos (70 por ciento) en el lado izquierdo. Los FIO estaban más frecuentemente localizados en relación al primer y segundo premolares, en 22 cráneos (36,7 por ciento) en el lado derecho y en 17 cráneos (28,3 por ciento) en el lado izquierdo...
