O Crescimento das vilosidades e criptas intestinais de galinhas e ratos durante o desenvolvimento embrionário e pós-natal. Um estudo comparativo usando parâmetros morfométricos

The development of the villi and crypts determines the functionality of the small intestinal mucosa of birds and mammals. This work aimed to carry out a comparative study of the growth of the villi and crypts in chickens and rats during development. The measurements of the villus height and crypt depth were carried out using the Image J program. The results demonstrated that the growth of the villi occurred faster in chickens than in rats. The villi were well-formed on the 17^th in chicken embryos, reaching a maximum height of 1000 µm on the 10^th day after hatching. The villi emergence occurred later in the embryonic period of rats, and their growth was gradual, reaching a maximum height of 500 µm on the 25^th postnatal day. The formation and growth of the crypts was equally faster in chickens than in rats. The chicken crypts were already differentiated at hatch, and their growth occurred until the 10^th posthatching day. However, rats exhibited crypts with greater depth than chickens in adulthood. Chicks on the third posthatch day had approximately 92% of the villus height and 42% of the crypt depth above 250 µm and 90 µm, respectively. In contrast, rats on the third postnatal day had about 13% of the villus height and 4% of the crypt depth above 250 µm and 60 µm, respectively. These differences in the emergence and growth of the villi and crypts between chickens and rats could be related to the distinct nutritional requirements soon after birth.

EXPERIÊNCIAS PSICÓTICAS DE ADOLESCENTES CONSUMIDORES DE DROGAS, CASO DE ALUNOS DO ENSINO MÉDIO

2022-09-13T13:22:17+00:00

Introduction: Drug consumption by adolescents in school environments in recent times tends to increase more and more. Objective: To evaluate the psychotic experiences of adolescents and young drug users. Method: it is a qualitative study with a phenomenological focus using the semi-structured interview, applied to four young adolescents in the city of Nampula-Mozambique, of these three were male and one was female, all over 18 years old. The interviews were conducted over the phone, after the first attempts failed due to the Covid-19 pandemic. The analysis and processing of the interviews was carried out using Saldaña's (2013) coding method. Results: A prevalence of alcohol and other drug consumption by adolescents and young people was observed, even in a school environment. These experiences negatively affect and disrupt the health of the young adolescent and society. Conclusion: It is opportune that schools and government entities provide strategies for preventing and combating drugs in school environments. It is also suggested the need to develop projects and programs that ensure preventive actions, incorporating psychologists and similar professionals into the school environment to ensure school and community health.

DENTAL IMPLANT IDENTIFICATION THROUGH RADIOGRAPHIC IMAGES SUBTITLE: IDENTIFICATION OF DENTAL IMPLANTS BY X-RAY

2024-10-29T19:35:32+00:00

The identification of dental implants by clinicians may be achieved through morphometric measurements and may be used in the field of forensic dentistry. This study compares the real measurements and the measurement of digital radiography of dental implants to establish their respective correlations with the use of software. The study was performed with six implants from five different manufacturers. All images were obtained using dental films with different angles. Thus, the dental films were measured using a specific software developed. These measurements were then compared with the dental implant measurements. The results showed that the comparison of the measures of the platforms of the implants with the measures of their images at different angulations resulted in no statistical difference. With the horizontal calibration of the images, comparisons between the measurements of the lengths at 20 and 40 degrees and the measurements of the implants were statistically significant. The comparison between implant lengths and their images, performed with the system vertically calibrated, did not reveal a statistically significant difference for any of the three angular comparisons. The software presented accurate measurements in angular variations in relation to the implant, proving that although parallelism is important, it is
not indispensable in the identification of implants.

RELATIONSHIP OF INTESTINAL DYSBIOSIS AND THE TRIGGER OF RHEUMATOID ARTHRITIS: A LITERATURE REVIEW

2024-10-29T20:03:22+00:00

The comprehension of the correlation between intestinal dysbiosis and rheumatoid arthritis (RA) could introduce new perspectives in the treatment of this autoimmune disease. Through a literature review, evidence correlating intestinal dysbiosis with the triggering of RA was sought. A review was carried out through a search in the MEDLINE/PubMed, Biblioteca Virtual em Saúde (BVS) and Embase databases between 2020/2023, in Portuguese and English, using the methodology was employed, where: P=individuals with RA; I=analysis of intestinal microbiota with dysbiosis; C=analysis of healthy intestinal microbiota; O=laboratory analysis; T=literature review. It was observed that intestinal dysbiosis causes local and systemic immunological alterations and changes in the intestinal epithelium’s resistance to the passage of antigens. The pathophysiological mechanisms are: A) Damage to the intestinal barrier integrity caused by the bacterium Collinsella aerofaciens (C. aerofaciens) in the stage I of RA; B) Decreased metabolism of glycosaminoglycans, bone loss, increase of pro-inflammatory cytokines caused by bacteria such as Escherichia coli (E. coli), Bacteroides uniformis (B. uniformis), Bifidobacterium dentium (B. dentium), Veillonella parvula (V. parvula), and Bacteroides plebeius (B. plebeius) in the stages II
e III; C) In the stage IV, in addition to changes from the stages II and III, there is cellular mimicry provoked by bacteria including Eggerthella lenta (E. lenta), Bifidobacterium longum (B. longum), B. dentium, B. plebeius, and Prevotella copri (P. copri). Managing the intestinal microbiota of patients with RA may be differential in the adequate management of this disease.

INFORMATIZAÇÃO DE IMAGENS DE INSTRUMENTAIS CIRÚRGICOS NO CENTRO DE MATERIAL E ESTERILIZAÇÃO

2024-02-02T14:00:36+00:00

O Centro de Material e Esterilização (CME) é considerado uma unidade de assistência indireta, responsável pelo reprocessamento de produtos para saúde. Objetiva-se relatar a inclusão do descritivo e imagens de instrumentais cirúrgicos no sistema informatizado para gestão de materiais. Trata-se de relato de experiência no CME de um hospital universitário no interior do Paraná, no período de março a junho de 2023. Foram acrescentadas imagens de 702 instrumentais cirúrgicos, sendo 74 caixas cirúrgicas e 626 materiais avulsos, de diversas especialidades, como ortopedia, cirurgia geral, otorrinolaringologia, odontologia, urologia, vascular e ginecologia. Espera-se que a implementação dos descritivos e imagens no sistema informatizado facilite o reconhecimento dos instrumentais reprocessados, minimizando os erros no processo e aumentando a eficiência e segurança dos serviços prestados. A adesão à tecnologia na saúde, aliada à educação permanente, é fundamental para o aprimoramento contínuo dos processos e serviços prestados.

Rights of patients undergoing dental treatment: beyond the Dental Code of Ethics

2024-03-25T13:54:37+00:00

Patients' Rights are the specific rights of people undergoing health treatment arising from the professional-patient relationship. These rights are derived from Human Rights based on the patient's intrinsic dignity in respect for their self-determination and bodily integrity. The purpose of this work is to identify and specify the rights of patients undergoing dental treatment. A normative theoretical research was carried out, under the theoretical framework of Aline Albuquerque's works that deal with Patients' Rights, also involving analysis of international legislation and Brazilian legislation that dealt with these rights. The following rights of patients undergoing dental treatments, arising from Human Rights, were identified and specified: 1) right to life; 2) right to privacy; 3) right not to be discriminated against; 4) right to freedom; 5) right to health; 6) right to information and 7) right not to be subjected to inhuman and degrading treatment.
